When making a form-data request using OkHttp, a status code of 400 is returned. Here is the captured packet phenomenon.
It seems that when there is a Content-Length field between the boundaries, this situation occurs.

However, when I use curl to make a form-data request, it works fine, as shown below.

I have debugged cpp-httplib using Visual Studio 2019 breakpoints and found that it may be related to the following code snippet.

@yuanqi-pythoner thanks for the report. I fixed it and it will be included in the next release '0.14.3'.
