APNS Notifications: Python HTTP/2 POST request returning 404 ({"reason":"BadPath"})

I am developing a watchOS app and I want to send push notifications to my users. I have enabled "Push Notifications" in signing and capabilities and a file called "app_name WatchKit Extension" was generated containing one entitlement called APS environment whose value is set to "development".
I have also generated a .p8 file in the Apple Developer Website with the authentication key and that also gives me the key id.
I have created a Swift class called App Delegate that conforms to UNUserNotificationCenterDelegate. I have implemented the method applicationDidFinishLaunching from where I call WKExtension.shared().registerForRemoteNotifications(). Then I implemented the didRegisterForRemoteNotifications where I receive the device token and convert it into a string by executing these lines of code:
let tokenParts = deviceToken.map { data in String(format: "%02.2hhx", data) }
let token = tokenParts.joined()
Then I send the token to the server. In the server I have a Python script that makes the post request to https://api.sandbox.push.apple.com:443 with the headers and notification payload. However, I always get a 404 error ({"reason":"BadPath"}).
I don't know what I am doing wrong. Am I configuring anything wrong? This is the Python script I am using:
import time
import httpx
import asyncio
import jwt
ALGORITHM = 'ES256'
APNS_AUTH_KEY = "path to .p8 file"
f = open(APNS_AUTH_KEY)
secret = f.read()
apns_token = jwt.encode(
{
'iss': 'cert_id',
'iat': time.time()
},
secret,
algorithm=ALGORITHM,
headers={
'alg':ALGORITHM,
'kid':'key_id'
}
)
dev_server = "https://api.sandbox.push.apple.com:443"
device_token = "9fe2814b6586bbb683b1a3efabdbe1ddd7c6918f51a3b83e90fce038dc058550"
headers = {
'method': 'POST',
'path': '/3/device/{0}'.format(device_token),
'autorization': 'bearer {0}'.format(apns_token),
'apns-push-type': 'myCategory',
'apns-expiration': '0',
'apns-priority': '10',
}
payload = {
"aps" : {
"alert" : {
"title" : "Hello Push",
"message": "This is a notification!"
},
"category": "myCategory"
}
}
async def test():
async with httpx.AsyncClient(http2=True) as client:
client = httpx.AsyncClient(http2=True)
r = await client.post(dev_server, headers=headers, data=payload)
print(r.text)
print(r)
asyncio.run(test())
Is there anything wrong with the way I am setting things up or performing the post request?
Thank you for your help!

Swift HTTP session not sending actual Request

So I have some Swift code that send a request to my local host
//
// ContentView.swift
// Shared
//
// Created by Ulto4 on 10/23/21.
//
import SwiftUI
struct ContentView: View {
var body: some View {
VStack{
Text("Hello, world!")
.padding()
Button(action : {
self.fu()
}, label: {
Image(systemName: "pencil").resizable().aspectRatio(contentMode:.fit)
})
}
}
func fu(){
let url = URL(string: "http://127.0.0.1:5000/232")
guard let requestUrl = url else { fatalError() }
var request = URLRequest(url: requestUrl)
request.httpMethod = "GET"
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
if let error = error {
print("Error took place \(error)")
return
}
if let response = response as? HTTPURLResponse {
print("Response HTTP Status code: \(response.statusCode)")
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
}
However, on my Flask app there are no get requests coming in and the function isn't running. There also isn't anything printing to the console.
I am fairly new to swift so I don't really know how to fix this.
Is there any other way to send requests in swift, if not, How would I fix this?

You are creating the URLSessionDataTask, but you never start it. Call task.resume(), e.g.
func performRequest() {
guard let url = URL(string: "http://127.0.0.1:5000/232") else {
fatalError()
}
let task = URLSession.shared.dataTask(with: url) { data, response, error in
if let error = error {
print("Error took place \(error)")
return
}
if let response = response as? HTTPURLResponse {
print("Response HTTP Status code: \(response.statusCode)")
}
}
task.resume() // you must call this to start the task
}
That having been said, a few caveats:
You are doing http rather than https. Make sure to temporarily enable insecure network requests with app transport settings, e.g.
You didn’t say if this was for macOS or iOS.
If running on physical iOS device, it will not find your macOS web server at 127.0.0.1 (i.e., it will not find a web server running on your iPhone). You will want to specify the IP number for your web server on your LAN.
If macOS, make sure to enable outbound network requests in the target’s “capabilities”:
You asked:
Is there any other way to send requests in swift?
It is probably beyond the scope of your question, but longer term, when using SwiftUI, you might consider using Combine, e.g., dataTaskPublisher. When running a simple “what was the status code” routine, the difference is immaterial, but when you get into more complicated scenarios where you have to parse and process the responses, Combine is more consistent with SwiftUI’s declarative patterns.
Let us consider a more complicated example where you need to parse JSON responses. For illustrative purposes, below I am testing with httpbin.org, which echos whatever parameters you send. And I illustrate the use of dataTaskPublisher and how it can be used with functional chaining patterns to get out of the mess of hairy imperative code:
struct SampleObject: Decodable {
let value: String
}
struct HttpBinResponse<T: Decodable>: Decodable {
let args: T
}
class RequestService: ObservableObject {
var request: AnyCancellable?
let decoder = JSONDecoder()
#Published var status: String = "Not started yet"
func startRequest() {
request = createRequest().sink { completion in
print("completed")
} receiveValue: { [weak self] object in
self?.status = "Received " + object.value
}
}
func createRequest() -> AnyPublisher<SampleObject, Error>{
var components = URLComponents(string: "https://httpbin.org/get")
components?.queryItems = [URLQueryItem(name: "value", value: "foo")]
guard let url = components?.url else {
fatalError("Unable to build URL")
}
return URLSession.shared.dataTaskPublisher(for: url)
.map(\.data)
.decode(type: HttpBinResponse<SampleObject>.self, decoder: decoder)
.map(\.args)
.receive(on: DispatchQueue.main)
.eraseToAnyPublisher()
}
}
struct ContentView: View {
#ObservedObject var requestService = RequestService()
var body: some View {
VStack{
Text("Hello, world!")
.padding()
Button {
requestService.startRequest()
} label: {
Image(systemName: "pencil").resizable().aspectRatio(contentMode:.fit)
}
Text(requestService.status)
}
}
}
But, like I said, it is beyond the scope of this question. You might want to make sure you get comfortable with SwiftUI and basic URLSession programming patterns (e.g., making sure you resume any tasks you create). Once you have that mastered, you can come back to Combine to write elegant networking code.
FWIW, like workingdog said, you could also use the new async-await rendition of data(for:delegate:). But when in the declarative world of SwiftUI, I would suggest Combine.

C# Post Request Problem Comparing To Python

i have problem making post request in c#, i'm trying to make post request using c#
var values = new Dictionary<string, string>{
{ "email", "hello" },
{ "password", "world" }
};
var content = new FormUrlEncodedContent(values);
var response = await client.PostAsync("myapilink", content);
var responseString = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseString);
then i get 403 forbidden error code with message [ access denied], so when i try this request in python with the same api, same data, same every thing, using requests library
url = 'myapi.com'
data = F"email={email}&password={password}"
req = requests.post(url, data=data)
src = req.text
print(src)
i got another source, [ invalid username or password ] and that is the right source [ that should appear to me ] not like c#, so idont know is that c# problem or problem in httpclient in c#, what can i do with this ?

Parsing JSON feed with Ruby for use in Dashing Dashboard

First post here, so ya know, be nice?
I'm setting up a dashboard in Dashing (http://dashing.io/) using a JSON feed on a server, which looks like:
{
"error":0,
"message_of_the_day":"Welcome!",
"message_of_the_day_hash":"a1234567890123456789012345678901",
"metrics":{
"daily":{
"metric1":"1m 30s",
"metric2":160
},
"monthly":{
"metric1":"10m 30s",
"metric2":"3803"
}
},
I have been experimenting with grabbing the data from the feed, and have managed to do so by Python with no issues:
import json
import urllib2
data = {
'region': "Europe"
}
req = urllib2.Request('http://192.168.1.2/info/handlers/handler.php')
req.add_header('Content-Type', 'application/json')
response = urllib2.urlopen(req, json.dumps(data))
print response.read()
However I haven't yet been successful, and get numerous errors in Ruby.
Would anyone be able to point me in the right direction in parsing this in Ruby?
My attempts to write a basic script, (keeping it simple and outside of Dashing) don't pull through any data.
#!/usr/bin/ruby
require 'httparty'
require 'json'
response = HTTParty.get("http://192.168.1.2/info/handlers/handler.php?region=Europe")
json = JSON.parse(response.body)
puts json

In python code you are sending a JSON and adding a header. I bet it makes sense to do that in ruby as well. The code below is untested, since I can’t test it, but it should lead you into the right direction:
#!/usr/bin/ruby
require 'httparty'
require 'json'
response = HTTParty.post(
"http://192.168.1.2/info/handlers/handler.php",
headers: {'Content-Type', 'application/json'},
query: { data: { 'region' => "Europe" } }
# or maybe query: { 'region' => "Europe" }
)
puts response.inspect

Need Example of passing Jasper Reports Parameters for REST v2 API using JSON

When I look at the documentation for passing parameters to the Jasper Report REST 2 API here: http://community.jaspersoft.com/documentation/jasperreports-server-web-services-guide/v550/running-report-asynchronously I see that I need to have a "parameters" dict. The example in the link shows the XML which is not all that useful since it's unclear exactly what the equivalent JSON should look like. The closest I could find is in this link: http://community.jaspersoft.com/documentation/jasperreports-server-web-services-guide/v56/modifying-report-parameters. Now, I am sending the equivalent of that to the server (and every other permutation I can think of), and I continue to get a "400 Client Error: Bad Request" back. I could really use an exact example of the python code to generate the required "parameters" parameter for say "my_parameter_1="test_value_1".
Here is my current POST data (with a few params missing for brevity). I know this is correct since the report works fine if I omit the "parameters" parameter:
{
'outputFormat': 'pdf',
'parameters': [{'name': 'ReportID', 'value': ['my_value_1']}],
'async': 'true',
'pages': '',
'interactive': 'false'
}

Nice Job there Staggart. I got it now. Because I wasn't reading with max. scrutinity, I wasted some additional time. So the interested coder is not only advised to be aware of the nested, syntactictally interesting reportParameter-property, but especially that the value-property inside that is an array. I suppose one could pass some form of Lists/Arrays/Collections here?
What irritated me was, if I should construct more than one "reportParameter" property, but that would be nonsense according to
Does JSON syntax allow duplicate keys in an object.
So just for the record, how to post multiple parameters:
{
"reportUnitUri": "/reports/Top10/Top10Customers",
"async": true,
"freshData": true,
"saveDataSnapshot": false,
"outputFormat": "pdf",
"interactive": false,
"ignorePagination": true,
"parameters": {
"reportParameter": [
{
"name": "DATE_START_STRING",
"value": ["14.07.2014"]
},
{
"name": "DATE_END_STRING",
"value": ["14.10.2014"]
}
]
}
}
If someone accidently is struggling with communicating with jasper via REST and PHP. Do yourself a favour and use the Requests for PHP instead of pure CURL. It even has a fallback for internally using Sockets instead of CURL, when latter isn't available.
Upvote for you Staggart.

OK, thanks to rafkacz1 # http://community.jaspersoft.com/questions/825719/json-equivalent-xml-post-reportexecutions-rest-service who posted an answer, I figured it out. As he report there, the required format is:
"parameters":{
"reportParameter":[
{"name":"my_parameter_1","value":["my_value_1"]}
]
}
Pay particular attention to the plurality of "reportParameter".

Here is an example that worked for me. Im using Python 2.7, and the community edition of Jaspersoft. Like the C# example above, this example also uses the rest v2 which made it very simple for me to download a pdf report quickly
import requests
sess = requests.Session()
auth = ('username', 'password')
res = sess.get(url='http://your.jasper.domain:8080/jasperserver/', auth=auth)
res.raise_for_status()
url = 'http://your.jasper.domain:8080/jasperserver/rest_v2/reports/report_folder/sub_folder/report_name.pdf'
params = {'Month':'2', 'Year':'2017','Project': 'ProjectName'}
res = sess.get(url=url, params=params, stream=True)
res.raise_for_status()
path = '/path/to/Downloads/report_name.pdf'
with open(path, "wb") as f:
f.write(res.content)

Here's a full example about generate a report using Rest V2, in my case it's running on C#:
try {
var server = "http://localhost:8080/jasperserver";
var login = server + "/rest/login";
var report = "/rest_v2/reports/organization/Reports/report_name.pdf";
var client = new WebClient();
//Set the content type of the request
client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
//Set the username and password
NameValueCollection parametros = new NameValueCollection();
parametros.Add("j_username", "jasperadmin");
parametros.Add("j_password", "123456");
//Request to login
client.UploadValues(login, "POST", parametros);
//Get session cookie
string session = client.ResponseHeaders.Get("Set-Cookie");
//Set session cookie to the next request
client.Headers.Add("Cookie", session);
//Generate report with parameters: "start" and "end"
var reporte = client.DownloadData(server + report + "?start=2015-10-01&end=2015-10-10");
//Returns the report as response
return File(reporte, "application/pdf", "test.pdf");
}catch(WebException e){
//return Content("There was a problem, status code: " + ((HttpWebResponse)e.Response).StatusCode);
return null;
}
