W (12405) httpd_txrx: httpd_resp_send_err: 431 Request Header Fields Too Large - Header fields are too long for server to interpret 1. 2. 解决: 如下 配置最大HTTP请求头长度修改为1024就可以了。 Component config ---> HTTP Server ---> (1024) Max HTTP Request Header Length // 默认是 ...
idf.py menuconfig Component config -> HTTP Server -> Max HTTP Request Header Length 将512改成1024。 编译烧写,再测试: 在浏览器输入http://192.168.0.102 串口显示: 浏览器显示 5. 读取URL请求串和参数 请求hello,带3个参数 http://192.168.0.102:80/hello?query1=abc&query2=ABD&query3=123 浏览器...

上述代码分配了一个大小为MAX_HTTP_OUTPUT_BUFFER的8位宽的内存块。三、使用cJSON库 1. 加载cJSON库 在 CMakeLists.txt中添加 json：idf_component_register(SRCS "main.c" "network/wifi.c" "network/tcp_server.c" "network/tcp_client.c" "network/http_request.c" INCLUDE_DIRS "network/include" ...
