I want to upload a file using REST and python. I am able to do it using Postman. But when I take the Python code from Postman and try to execute it on my own using requests module, I get the below error. Please help.
import requests
url = "https://url******"
payload = "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition:
form-data; name=\"file\"; filename=\"Path to file"\r\n\r\n\r\n------
WebKitFormBoundary7MA4YWxkTrZu0gW--"
headers = {
'content-type': "multipart/form-data; boundary=----
WebKitFormBoundary7MA4YWxkTrZu0gW",
'auth_token': auth_token,
'cache-control': "no-cache",
}
response = requests.request("POST", url, data=payload, headers=headers,
verify=False)
print(response.text)
>>> response.text
u'{"message":"Required request part \'file\' is not
present","detailedMessage":"
","errorCode":-1,"httpStatus":500,"moreInfo":""}'
I faced the same issue when I tried generating the python code from insomnia for a similar request. I fixed it by making the following changes to my python code:
import requests
url = "https://url******"
files = { 'file': ('file.wav', open('/path/to/file.wav', "rb"), 'audio/wave') }
headers = { 'auth_token': auth_token }
response = requests.request("POST", url, files=files, headers=headers)
print(response.text)
This problem is caused by 'Content-Type': 'multipart/form-data; boundary=---- WebKitFormBoundary7MA4YWxkTrZu0gW' setting on the header. When you use files this setting will no longer be necessary.
In my case the file was a wav file, the mime type can be changed accordingly or removed altogether (worked for me).
It seems that the error appear on the server you post to because of getting wrong data.
I don't have the url you post to so i don't know the correct data form.
Try to read the reference clearly will help you.
I have faced the same issue while upload files using requests.
1. By removing content type from headers
2. Don't do json.dumps on payload
will solve the problems.
import requests
file_path='/home/ubuntu/workspace/imagename.jpg'
file_name=os.path.basename(file_path)
namew, extension = os.path.splitext(file_name)
type_dict = {'.pdf': 'application/pdf',
'.jpeg': 'image/jpeg',
'.png': 'image/png',
'.tiff': 'image/tiff', '.jpg': 'image/jpg'}
url = "https://dev.example.com/upload"
filetype = type_dict.get(extension, 'application/octet-stream')
payload={}
files=[
('file',(file_name,open(file_path,'rb'),filetype))
]
headers = {
'Authorization': 'Token',
}
response = requests.request("POST", url, headers=headers, data=payload, files=files)

I want to call POST from micropython to Django webserver.
The POST payload shows up as empty when called from the micropython code.
When the same code is ran with C-Python, it does show up with the filled payload.
Here is the micropython code -
import urequests as requests
url = "http://192.168.0.33:8000/species/"
payload={'name': 'test12',
'classification': 'sheep12',
'language': 'sheep_lang12'}
files=[
]
headers = { 'Content-Type': 'application/x-www-form-urlencoded'}
response = requests.request("POST", url, headers=headers, data=payload)
print('success')
print(response.text)
The output of response.txt is -
{'name':'',classification:'',language:''}
I also tried using an alternative of the payload to use JSON. Here is the JSON payload attempt
import urequests as requests
import ujson as json
url = "http://192.168.0.33:8000/species/"
payload={'name': 'test12',
'classification': 'sheep12',
'language': 'sheep_lang12'}
files=[
]
headers = { 'Content-Type': 'application/x-www-form-urlencoded'}
response = requests.request("POST", url, headers=headers, data=json.dumps(payload))
print('success')
print(response.text)
What did I miss here ?
I'm trying to access the Letterboxd api to get an authentification token but I keep getting Bad Request feedback. Here's my code:
import requests
import urllib
import json
headers = {
'Content-Type': 'application/x-www-form-urlencoded',
'Accept': 'application/json'
}
url = 'https://api.letterboxd.com/api/v0/auth/token'
body = {
'grant_type': 'password',
'username': 'myname',
'password': 'mypassword'
}
response = requests.post(
url+urllib.parse.urlencode(headers), data=json.dumps(body))
print('\n')
print(response.text)
Any idea what I did wrong? The response is just an HTTP document with no info besides the Error message "400 Bad Request". Heres the documentation if it helps https://api-docs.letterboxd.com/#auth
First: I can't test if all code works.
You send headers in url but you should send it as part of headers=.
And when you use module requests then you can use json=body instead of data=json.dumps(body)
response = requests.post(url, headers=headers, json=body)
But header 'Content-Type': 'application/x-www-form-urlencoded' suggests that you will send data as form data, not json data - which needs data=body without converting to json
response = requests.post(url, headers=headers, data=body)
EDIT:
In your link to documentation I see link to python module (in part "Example implementations") - so maybe you should use it instead of writing own code because documentation mentionts something about "All API requests must be signed" (in part "Request signing") - and this may need extra code to create it.
I've been trying to make a Post Request to my CRM API. The CRM API is very vague:
"You can use POST request when you wish to create records. You POST a JSON encoded string to the servers and it will return a single instance of the record."
POST /{object_name}
Example:
Request URL (POST):
/accounts
Request Body (JSON):
{
"name": "testing API"
}
I've had plenty of success making GET requests regularly, but POST is not working out so easily.
url = "https://apiv4.reallysimplesystems.com/accounts?<KEY>"
payload = {"name":"Ziggy","owner":"XYZ","addresscounty/state":"Awe","source":"Space"}
headers = {
'Content-Type': 'application/json',
'Cookie': 'XSRF-TOKEN=<TOK>; really_simple_systems_session=<KEY>'
}
response = requests.post(url, headers=headers, data=payload)
I get a status code 200 when I run this, but I'm really looking for that 201. The only clue that I've got to follow at this point is that when I run:
response.json()
I get the error:
JSONDecodeError: Expecting value: line 1 column 1 (char 0)
I've tried switching the response parameters to json:
response = requests.post(url, headers=headers, json=payload)
I've tried ensuring that my payload is json by using json.dumps():
payload = {"name":"Ziggy","owner":"XYZ","addresscounty/state":"Awe","source":"Space"}
payload = json.dumps(payload)
And I've tried all sorts of other shenanigans that I can't even recall at this point. Does anyone have any idea where I'm going wrong here? The 200 status code makes me feel painfully close.
Replace <AUTH_TOKEN> with your auth token
url = "https://apiv4.reallysimplesystems.com/accounts/"
payload = {"name":"Ziggy"}
headers = {
'Content-Type': 'application/json',
'Authorization': 'Bearer <AUTH_TOKEN>',
}
response = requests.post(url, headers=headers, data=payload)
Problem solved:
import json
import requests
url = "https://apiv4.reallysimplesystems.com/accounts"
payload = {"name":"RSS Test Joe Bloggs","addresscounty/state":"Maryland","source":"Word of Mouth"}
payload = json.dumps(payload)
headers = {
'Content-Type': 'application/json',
'Authorization': 'Bearer <AUTH KEY>'
}
response = requests.post(url, headers=headers, data=payload)
Rather than using Postman's code which included the in the URL and used :
'Cookie': 'XSRF-TOKEN=<TOK>; really_simple_systems_session=<KEY>'
I replaced it with a standard Authorization header. Secondly, I found that using json.dumps(payload) and json = payload was resulting in a Bad Request.
Could someone take a look at this code and let me know if there's something I'm doing wrong:
import requests
url = "https://api-end-point"
payload = {"grant_type": "client_credentials", "client_id":"my_ic", "client_secret": "not_now_please"}
headers = '{"accept": "application/json", "content-type": "application/json"}'
response = requests.request("POST", url, data=payload, headers=headers)
print(response.text)
For some reason it's throwing error.
{"type":"http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html","title":"Bad Request","status":400,"detail":"JSON decoding error: Syntax error, malformed JSON"}
So first use json instead of data, second don't use ' around the headers, or actually you don't need to specify headers:
import requests
url = "https://api-end-point"
payload = {"grant_type": "client_credentials", "client_id":"my_ic", "client_secret": "not_now_please"}
response = requests.request("POST", url, json=payload)
print(response.text)
The page does not contain json/application but html/text. If you remove the headers then it works:
response = requests.request(method="POST", url=url, data=payload)
If you have special needs to specify in the headers add details to your question
I am attempting to access the NJTransit API, I have successfully queried it using the Postman application but no matter what I try I cannot get python to successfully return the desired query.
Using suds:
from suds.client import Client
url = "http://traindata.njtransit.com:8090/NJTTrainData.asmx?wsdl"
client = Client(url, cache = None)
from suds.sax.element import Element
auth = Element('UserCredentials')
auth.append(Element('userName').setText(my_username))
auth.append(Element('password').setText(my_password))
client.set_options(soapheaders = auth)
client = Client(url, cache = None)
result = client.service.getTrainScheduleJSON("NY")
This results in "none".
I've also attempted to use the preformatted request suggested by the Postman app, however I keep getting a 404 error.
import requests
url = "http://traindata.njtransit.com:8090/NJTTrainData.asmx"
querystring = {"wsdl":""}
payload = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n <soap:Header>\n <UserCredentials xmlns=\"http://microsoft.com/webservices/\">\n <userName>---</userName>\n <password>---</password>\n </UserCredentials>\n </soap:Header>\n <soap:Body>\n <getTrainScheduleJSON xmlns=\"http://microsoft.com/webservices/\">\n <station>NY</station>\n </getTrainScheduleJSON>\n </soap:Body>\n</soap:Envelope>"
headers = {
'content-type': "text/xml; charset=utf-8",
'host': "traindata.njtransit.com",
'soapaction': "http//microsoft.com/webservices/getTrainScheduleJSON"
}
response = requests.request("POST", url, data=payload, headers=headers, params=querystring)
print(response.text)
I would greatly appreciate any help/insight.
You never want to set the "Host" header, this is will be done by requests.
The 404 is triggered by the wrong SOAPAction. There is a missing : after http.
The following snippet is working fine for me.
import requests
url = "http://traindata.njtransit.com:8090/NJTTrainData.asmx"
querystring = {"wsdl":""}
payload = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n <soap:Header>\n <UserCredentials xmlns=\"http://microsoft.com/webservices/\">\n <userName>---</userName>\n <password>---</password>\n </UserCredentials>\n </soap:Header>\n <soap:Body>\n <getTrainScheduleJSON xmlns=\"http://microsoft.com/webservices/\">\n <station>NY</station>\n </getTrainScheduleJSON>\n </soap:Body>\n</soap:Envelope>"
headers = {
'content-type': "text/xml; charset=utf-8",
'soapaction': 'http://microsoft.com/webservices/getTrainScheduleJSON'
}
response = requests.request("POST", url, data=payload, headers=headers, params=querystring)
print response
print(response.text)
