Get a Json file that represents device(object) from a specific folder and generating kafka event

I need make tool using Python that takes JSON file(device) from a folder(devices) and generates kafka events for the device.events topic. before generating event it has to check if device exists in folder.
I wrote this but i still dont know how to open file inside the folder.
import json
test_devices = r'''
{
"data": ["{\"mac_address\": null, \"serial_number\": \"BRUCE03\", \"device_type\": \"STORAGE\", \"part_number\": \"STCHPRTffOM01\", \"extra_attributes\": [], \"platform_customer_id\": \"a44a5c7c65ae11eba916dc31c0b885\", \"application_customer_id\": \"4b232de87dcf11ebbe01ca32d32b6b77\"}"],
"id": "b139937e-5107-4125-b9b0-d05d17ad2bea",
"source":"CCS",
"specversion":"1.0",
"time": "2021-01-13T14:44:18.972181+00:00",
"type":"` `",
"topic":"` `"
}
'''
data = json.loads(test_devices)
print(type(test_devices))
print(data)

Kafka is an implementation detail and doesn't relate to your questions.
how to open file inside the folder
import json
with open("/path/to/device.json") as f:
content = json.load(f)
print(content)
has to check if device exists in folder
import os.path
print("Exists? :", os.path.exists("/path/to/device.json"))

I am looking to create an API endpoint route that returns txt in a json format -Python

I'm new to developing and my question(s) involves creating an API endpoint in our route. The api will be used for a POST from a Vuetify UI. Data will come from our MongoDB. We will be getting a .txt file for our shell script but it will have to POST as a JSON. I think these are the steps for converting the text file:
1)create a list for the lines of the .txt
2)add each line to the list
3) join the list elements into a string
4)create a dictionary with the file/file content and convert it to JSON
This is my current code for the steps:
import json
something.txt: an example of the shell script ###
f = open("something.txt")
create a list to put the lines of the file in
file_output = []
add each line of the file to the list
for line in f:
file_output.append(line)
mashes all of the list elements together into one string
fileoutput2 = ''.join(file_output)
print(fileoutput2)
create a dict with file and file content and then convert to JSON
json_object = {"file": fileoutput2}
json_response = json.dumps(json_object)
print(json_response)
{"file": "Hello\n\nSomething\n\nGoodbye"}
I have the following code for my baseline below that I execute on my button press in the UI
#bp_customer.route('/install-setup/<string:customer_id>', methods=['POST'])
def install_setup(customer_id):
cust = Customer()
customer = cust.get_customer(customer_id)
### example of a series of lines with newline character between them.
script_string = "Beginning\nof\nscript\n"
json_object = {"file": script_string}
json_response = json.dumps(json_object)
get the install shell script content
replace the values (somebody has already done this)
attempt to return the below example json_response
return make_response(jsonify(json_response), 200)
my current Vuetify button press code is here: so I just have to ammend it to a POST and the new route once this is established
onClickScript() {
console.log("clicked");
axios
.get("https://sword-gc-eadsusl5rq-uc.a.run.app/install-setup/")
.then((resp) => {
console.log("resp: ", resp.data);
this.scriptData = resp.data;
});
},
I'm having a hard time combining these 2 concepts in the correct way. Any input as to whether I'm on the right path? Insight from anyone who's much more experienced than me?

You're on the right path, but needlessly complicating things a bit. For example, the first bit could be just:
import json
with open("something.txt") as f:
json_response = json.dumps({'file': f.read()})
print(json_response)
And since you're looking to pass everything through jsonify anyway, even this would suffice:
with open("something.txt") as f:
data = {'file': f.read()}
Where you can pass data directly through jsonify. The rest of it isn't sufficiently complete to offer any concrete comments, but the basic idea is OK.
If you have a working whole, you could go to https://codereview.stackexchange.com/ to ask for some reviews, you should limit questions on StackOverflow to actual questions about getting something to work.

Using python and suds, data not read by server side because element is not defined as an array

I am a very inexperienced programmer with no formal education. Details will be extremely helpful in any responses.
I have made several basic python scripts to call SOAP APIs, but I am running into an issue with a specific API function that has an embedded array.
Here is a sample excerpt from a working XML format to show nested data:
<bomData xsi:type="urn:inputBOM" SOAP-ENC:arrayType="urn:bomItem[]">
<bomItem>
<item_partnum></item_partnum>
<item_partrev></item_partrev>
<item_serial></item_serial>
<item_lotnum></item_lotnum>
<item_sublotnum></item_sublotnum>
<item_qty></item_qty>
</bomItem>
<bomItem>
<item_partnum></item_partnum>
<item_partrev></item_partrev>
<item_serial></item_serial>
<item_lotnum></item_lotnum>
<item_sublotnum></item_sublotnum>
<item_qty></item_qty>
</bomItem>
</bomData>
I have tried 3 different things to get this to work to no avail.
I can generate the near exact XML from my script, but a key attribute missing is the 'SOAP-ENC:arrayType="urn:bomItem[]"' in the above XML example.
Option 1 was using MessagePlugin, but I get an error because my section is like the 3 element and it always injects into the first element. I have tried body[2], but this throws an error.
Option 2 I am trying to create the object(?). I read a lot of stack overflow, but I might be missing something for this.
Option 3 looked simple enough, but also failed. I tried setting the values in the JSON directly. I got these examples by an XML sample to JSON.
I have also done a several other minor things to try to get it working, but not worth mentioning. Although, if there is a way to somehow do the following, then I'm all ears:
bomItem[]: bomData = {"bomItem"[{...,...,...}]}
Here is a sample of my script:
# for python 3
# using pip install suds-py3
from suds.client import Client
from suds.plugin import MessagePlugin
# Config
#option 1: trying to set it as an array using plugin
class MyPlugin(MessagePlugin):
def marshalled(self, context):
body = context.envelope.getChild('Body')
bomItem = body[0]
bomItem.set('SOAP-ENC:arrayType', 'urn:bomItem[]')
URL = "http://localhost/application/soap?wsdl"
client = Client(URL, plugins=[MyPlugin()])
transact_info = {
"username":"",
"transaction":"",
"workorder":"",
"serial":"",
"trans_qty":"",
"seqnum":"",
"opcode":"",
"warehouseloc":"",
"warehousebin":"",
"machine_id":"",
"comment":"",
"defect_code":""
}
#WIP - trying to get bomData below working first
inputData = {
"dataItem":[
{
"fieldname": "",
"fielddata": ""
}
]
}
#option 2: trying to create the element here and define as an array
#inputbom = client.factory.create('ns3:inputBOM')
#inputbom._type = "SOAP-ENC:arrayType"
#inputbom.value = "urn:bomItem[]"
bomData = {
#Option 3: trying to set the time and array type in JSON
#"#xsi:type":"urn:inputBOM",
#"#SOAP-ENC:arrayType":"urn:bomItem[]",
"bomItem":[
{
"item_partnum":"",
"item_partrev":"",
"item_serial":"",
"item_lotnum":"",
"item_sublotnum":"",
"item_qty":""
},
{
"item_partnum":"",
"item_partrev":"",
"item_serial":"",
"item_lotnum":"",
"item_sublotnum":"",
"item_qty":""
}
]
}
try:
response = client.service.transactUnit(transact_info,inputData,bomData)
print("RESPONSE: ")
print(response)
#print(client)
#print(envelope)
except Exception as e:
#handle error here
print(e)
I appreciate any help and hope it is easy to solve.

I have found the answer I was looking for. At least a working solution.
In any case, option 1 worked out. I read up on it at the following link:
https://suds-py3.readthedocs.io/en/latest/
You can review at the '!MessagePlugin' section.
I found a solution to get message plugin working from the following post:
unmarshalling Error: For input string: ""
A user posted an example how to crawl through the XML structure and modify it.
Here is my modified example to get my script working:
#Using MessagePlugin to modify elements before sending to server
class MyPlugin(MessagePlugin):
# created method that could be reused to modify sections with similar
# structure/requirements
def addArrayType(self, dataType, arrayType, transactUnit):
# this is the code that is key to crawling through the XML - I get
# the child of each parent element until I am at the right level for
# modification
data = transactUnit.getChild(dataType)
if data:
data.set('SOAP-ENC:arrayType', arrayType)
def marshalled(self, context):
# Alter the envelope so that the xsd namespace is allowed
context.envelope.nsprefixes['xsd'] = 'http://www.w3.org/2001/XMLSchema'
body = context.envelope.getChild('Body')
transactUnit = body.getChild("transactUnit")
if transactUnit:
self.addArrayType('inputData', 'urn:dataItem[]', transactUnit)
self.addArrayType('bomData', 'urn:bomItem[]', transactUnit)

How to accept any key in python json dictionary?

Here's a simplified version of the JSON I am working with:
{
"libraries": [
{
"library-1": {
"file": {
"url": "foobar.com/.../library-1.bin"
}
}
},
{
"library-2": {
"application": {
"url": "barfoo.com/.../library-2.exe"
}
}
}
]
}
Using json, I can json.loads() this file. I need to be able to find the 'url', download it, and save it to a local folder called library. In this case, I'd create two folders within libraries/, one called library-1, the other library-2. Within these folder's would be whatever was downloaded from the url.
The issue, however, is being able to get to the url:
my_json = json.loads(...) # get the json
for library in my_json['libraries']:
file.download(library['file']['url']) # doesn't access ['application']['url']
Since the JSON I am using uses a variety of accessors, sometimes 'file', other times 'dll' etc, I can't use one specific dictionary key. How can I use multiple. Would there be a modular way to do this?
Edit: There are numerous accessors, 'file', 'application' and 'dll' are only some examples.

You can just iterate through each level of the dictionary and download the files if you find a url.
urls = []
for library in my_json['libraries']:
for lib_name, lib_data in library.items():
for module_name, module_data in lib_data.items():
url = module_data.get('url')
if url is not None:
# create local directory with lib_name
# download files from url to local directory
urls.append(url)
# urls = ['foobar.com/.../library-1.bin', 'barfoo.com/.../library-2.exe']

This should work:
for library in my_json['libraries']:
for value in library.values():
for url in value.values():
file.download(url)

I would suggest doing it like this:
for library in my_json['libraries']:
library_data = library.popitem()[1].popitem()[1]
file.download(library_data['url'])

Try this
for library in my_json['libraries']:
if 'file' in library:
file.download(library['file']['url'])
elif 'dll' in library:
file.download(library['dll']['url'])
It just sees if your dict(created by parsing JSON) has a key named 'file'. If so, then use 'url' of the dict corresponds to the 'file' key. If not, try the same with 'dll' keyword.
Edit: If you don't know the key to access the dict containing the url, try this.
for library in my_json['libraries']:
for key in library:
if 'url' in library['key']:
file.download(library[key]['url'])
This iterates over all the keys in your library. Then, whichever key contains an 'url', downloads using that.

upload video file by path on python not working

I tried to upload video file using python, the problem is the system cannot find the file even though i write the path of file. my code is like this:
import os
import requests
#step 1
host = 'https://blablabla.com'
test = {
"upload_phase" : "start",
"file_size" : 1063565
}
params = {
"access_token":my_access_token,
"fields":"video_id, start_offset, end_offset, upload_session_id",
}
vids = requests.post(host, params=params, data=test)
vids = vids.json()
try:
video_id= vids["video_id"],
start_offset= vids["start_offset"],
end_offset= vids["end_offset"],
upload_session_id= vids["upload_session_id"]
except:
pass
print(vids)
###############################################################################
#step 2
###############################################################################
test = {
"upload_phase" : "transfer",
"start_offset" : start_offset,
"upload_session_id": upload_session_id,
"video_file_chunk": os.path.realpath('/home/def/Videos/test.mp4')
}
params = {
"access_token":my_access_token,
"fields":"start_offset, end_offset",
}
vids = requests.post(host, params=params, data=test)
vids = vids.json()
try:
start_offset= vids["start_offset"],
end_offset= vids["end_offset"]
except:
pass
print(vids)
Many way i tried, like os.path.abspath, os.path, os.path.dirname, os.path.basename, os.path.isfile, os.path.isabs, os.path.isdir it's still doesn't work. even i give import os.path or import os.

In your code you just send path to your file as the string to server, but not file itself. You should try something like:
my_file = {'file_to_upload': open(os.path.realpath('/home/def/Videos/test.mp4'),'rb')}
# You should replace 'file_to_upload' with the name server actually expect to receive
# If you don't know what server expect to get, check browser's devconsole while uploading file manually
vids = requests.post(host, params=params, files=my_file)
Also note that you might need to use requests.Session() to be able to handle cookies, access token...
