求对应Python Requests代码的等效curl命令（附代码示例）

Hey there! Let's work out the correct curl command that matches your Python Requests code.

First, let's recap your original Python code:

import requests 
response = requests.request("POST" , url = "https://services27.ieee.org/fellowsdirectory/getpageresultsdesk.html" , data = { 'pageNum': 3 } ) 
print(response.text)

The key thing here is that when you use data with a dictionary in Requests, it sends the payload as form-encoded data (Content-Type: application/x-www-form-urlencoded), not JSON. Your initial curl attempt was sending JSON, which is why it wasn't matching the Python request's behavior.

Correct Equivalent curl Command #

curl -X POST -d 'pageNum=3' https://services27.ieee.org/fellowsdirectory/getpageresultsdesk.html

Alternatively, if you want explicit URL encoding (useful if your values have special characters), you can use:

curl -X POST --data-urlencode 'pageNum=3' https://services27.ieee.org/fellowsdirectory/getpageresultsdesk.html

Quick Explanation #

• Your Python code uses data={'pageNum': 3}: This tells Requests to encode the key-value pair like an HTML form would, setting the appropriate Content-Type header automatically.
• The curl -d flag does exactly this—it sends form-encoded data, matching what your Python code is doing. Your original attempt used JSON syntax ({"pageNum": "3"}), which would set the Content-Type to application/json, which isn't what the Python request is sending.

If you want to double-check that the requests match, add the -v flag to the curl command to view the full request headers and payload, which should align with what Requests generates.
