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
这里简单介绍一下esp32轻量级webserver的框架的使用,此框架必须有TF卡支持,所以HTML文件和static文件都存在TF卡中,此框架的所有数据返回都采用chunked编码方式传输。 使用指南: typedef struct { char* url; vo…

In this article, we are going to learn aboutESP32 MicroPython Based Web Server. We willinterface DS18B20 Waterproof Temperature Sensor with ESP32& read the temperature. We will thencreate a Web Server&Send the DS18B20 Temperature Data to the Web Server. Using theIP Addresswe will monitor the ...
一、ESP32IDF创建WEB SERVER的流程 1. 配置web服务器 在ESP-IDF中,Web服务器使用httpd组件实现。我们需要先创建httpd_config_t结构体,指定服务器的端口、最大并发连接数、URI匹配处理器等选项。然后,我们通过调用httpd_start函数来启动Web服务器。 httpd_config_tconfig =HTTPD_DEFAULT_CONFIG();httpd_handle_tser...
xhttp.open("POST", "/wifi_data", true); xhttp.onreadystatechange = function() { if (xhttp.readyState == 4) { if (xhttp.status == 200) { console.log(xhttp.responseText); } else if (xhttp.status == 0) { alert("Server closed the connection abruptly!"); ...
the clients (The Web Browser and the ESP32 board) can send and receive information to the server without a request, and if configured correctly, the server can request the client to send or receive data. As we have said earlier, this process stays true if the client is a web bro...
