我在httpc库中，在cHTTP_REQUEST_INFO.content = json_data;（代码在41-48）赋值但实际服务器无法收到，请问content中的内容是在body里还是header中，还是我使用方式有问题？
Code: Select all
#include "app_elec_zendure_http.h"
/***********************************************************

http_req_t cHTTP_REQUEST_INFO = {
.type = HTTP_POST,
.resource = APIresource,
.version = HTTP_VER_1_1,
.content = NULL,
.content_len = 0,
};
