A、用 esp_http_client_config_t 结构体初始化 HTTP 客户端,如请求的 URL,请求方式(GET、POST 等),随后用 esp_http_client_init 函数初始化,会返回 esp_http_client_handle_t 类型的句柄,它就是个符号,后面调用的 HTTP 有关的函数需要用到它。 B、esp_http_client_open 函数打开连接; C、esp_http_clie...
does it mean that instead of calling the esp_http_client_perform, we have to instead do the following? 1. esp_http_client_open 2. esp_http_client_write 3. esp_http_client_fetch_headers 4. esp_http_client_read 5. esp_http_client_close ...

一、HTTP简介 HTTP(Hyper Text Transfer Protocol) 超文本传输协议,是一种建立在 TCP 上的无状态连接,整个基本的工作流程是客户端发送一个 HTTP 请求,说明客户端想要访问的资源和请求的动作,服务端收到请求之后,服务端开始处理请求,并根据请求做出相应的动作访问服务器资源,最后通过发送 HTTP 响应把结果返回给客户端...
