Hi guys I am using esp32 as http client to send multipart data which is basically a jpg file stored in spiffs. I need to send this file to server with the following information. Host: some url Content-Type: mul
cv2.imshow('server_frame', r_img) if cv2.waitKey(1) & 0xFF == ord('q'): break t1 = t2 # print("接收到的数据包大小:" + str(len(temp_data))) # 显示该张照片数据大小 temp_data = b'' # 清空数据 便于下一章照片使用 server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)...
首先定义tcp服务器的端口号,udp目标接收方的端口号,一个全局变量以保存本地IP地址: #define UDP_SERVER_PORT 8848 #define BROADCAST_PORT 8080 #define BROADCAST_INTERVAL_MS 5000 #define DEVICE_NAME "ESP32_SERVER" esp_ip4_addr_t ip_addr; 1. 2. 3. 4. 5. 6. 在自定义的wifi事件回调函数中获取...
wifi连接到sta,新建socket,连接到tcp server。 2、API函数 1、创建socket 代码语言:javascript 代码运行次数:0 运行 AI代码解释 int socket(int domain,int type,int protocol) domain:为地址族,也就是 IP 地址类型,常用的有 AF_INET 和 AF_INET6; type:数据传输方式/套接字类型,常用的有 SOCK_STREAM(流...

Note that there other methods that we can use to send data to the server, such as thewritemethod. client.print("Hello from ESP32!"); Since this is a simple introductory tutorial, we will not be expecting data from the server, so we can simply finish the connection by calling thestopme...
server发送一批数据，浏览器显示这些数据，同一时候保证与server的连接。当server须要再次发送一批数据时，...

also, the data are saving in an sd card at the same time. now I want to send the file that created in sd card to the webserver is it possible it would be great if someone can help me with the same example or any information ...
