I'm working on a project that reads online data from sensors and sends them to a webserver(with post.req) 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 someo...

I have a requirement where I need to upload a file which is in SPIFFS to my web server using HTTP. I could not find any example for it. It would be of great help if I can get a example code of how to do that. Thanks,

remote_addr.sin_addr.s_addr = inet_addr(SERVER_IP);returnESP_OK; } ④. 发送和接收的方法函数: 发送方法:sendto(mysocket, sendBuff, 1024, 0, (struct sockaddr *) &remote_addr, sizeof(remote_addr));,其中sendBuff是发送的数据。
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: multipart/form-data Accept: / Content-Disposition: form-data; name="file"; ...
我设计的是让esp32启动Ap或者链接已有wifi,然后启动webserver功能。 首先你需要一块esp32的开发板,然后搭建arduino支持esp32的开发环境,这个arduino开发esp32真的非常好, 既能支持arduino语法,也支持c、c++的esp32开发语音,还可以支持python,这些开发混着用也都支持esp32开发板,真实太方便太爽了。 1、下面图示...
