The amount of CURL POST data is too large and the information from the server cannot be received.

1. What I encountered while working on a project today was that when adjusting the interface POST data, the amount of POST data was too large, resulting in no return information being received.

2. After some searching on Baidu, I found out that I need to set a header information. After trying it, it didn’t work. I don’t know if it is a problem with the TP framework?
That’s it: curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));

3. So when the CURL POST data is too large, are there any other methods?

First use the interface debugging tool to test the interface, Google's postman or paw under mac, set the parameters, post, and see if there is return data;
The framework will not affect the curl access interface;
Check the code to make sure curl uses post Data passed
