"message":"Required request part \'file\' is not present"

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 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 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.
