It turns out that libcurl has never been used in the project.In the most recent cloud storage project, I used openstack to develop a cloud storage SDK C ++. Communication with the server is based on HTTP/HTTPS. First, use the Windows SDK and gradually port it to the Linux and Mac platforms.On the official website of curl ** http://curl.haxx.se/download.html#*, The libcurl package is compiled. The VC ++ comp

The previous two blogs introduced some of the simplest basic knowledge. Today I will apply it and write an HTTP client.
First, it contains the header file of curl.Next, two variables are defined for transmission. The first variable is wr_buf, which indicates the buffer zone in which incoming data will be written. Wr_index indicates the index currently written to the buffer.
