How to solve the problem of php request loss?

php curl post request is lost' 'Problem

Background:

Use a login-free authorization jump with a friend and found that Authorization fails occasionally. After checking the log, it is found that if the password contains the character ' ', the authorization will fail.

Through packet capture, it was found that when php uses curl to send a request, ' ' will be converted into spaces (The reason is unknown...it is suspected that curl does urldecode processing by default)

The solution is:

First urlencode the encrypted string before sending it.

P.S.

In addition, it seems that the packet capture and decoding of https requests on Linux are not easy to handle. Later, I used fiddler to capture packets on Windows. After setting up to capture https, I found that it was out of the php code. The request still failed to be captured. You need to set the proxy in curl to the 8888 port of fiddler to successfully capture

curl_setopt($ch,CURLOPT_PROXY,'127.0.0.1:8888');
