将 httpie post 请求转换为 python 请求库

Question

I have difficulties converting a post request using htppie to python requests.post. This question is in general about how to do such a conversion, but I will use the specific request I was doing as an example.

So I have the following post request using httpie, which works fine:

http post https://api.thegraph.com/subgraphs/name/graphprotocol/graph-network-mainnet query='{ indexers {
                id
               }
}'

However, when trying to send the same request using pythons requests library, I tried the following:

import requests

url = 'https://api.thegraph.com/subgraphs/name/graphprotocol/graph-network-mainnet'

query = """'{ indexers {
                id
                }
}'"""

print(requests.post(url, data = query).text)

This gives a server error (I tried many versions of this, as well as sending a dictionary for the data variable, and they all give the same error). The server error was GraphQL server error (client error): expected value at line 1 column 1 .

Regardless of what the server error is (which is probably server specific), this at least means that the two requests obviously are not exactly the same.

So how would I go about converting this httpie request to using pythons requests library (or any other python library for that matter)?

Answer 1

To pass request payload, you need pass json as string (I used json.dumps() for conversion). To pass body as form-data, pass just dict.

import json
import requests

url = 'https://api.thegraph.com/subgraphs/name/graphprotocol/graph-network-mainnet'

payload=json.dumps({'query': '{indexers {id}}'})
headers = {
  'Content-Type': 'application/json',
}

response = requests.post(url, headers=headers, data=payload)

Note. I recommend that you try to make this request in Postman and then you can convert the code to Python right in Postman.
