制作使用Arduino的一个HTTP POST请求 [英] Making a http POST request using Arduino

问题描述

我想发布的信息对我创建和托管的Web项目的API。我不知道确切的格式是HTTP POST请求。每次我尝试，我得到HTTP 400错误与存在无效的动词。

I am trying to post information to an API on a web project that I have created and hosted. I am not sure what the exact format is for the HTTP POST request. Every time I try I get HTTP 400 errors with the message that there is "an invalid verb".

样code：

byte server[] = {"our IP"}
..
..

client(server, 80)
..
..
client.println("POST /Api/AddParking/3");

它连接到没有任何问题提供的IP地址，但我回来在上面提到的HTTP错误code 400，我不知道我是否应该包括我的职务或与内容后，HTTP版本 - 长或任何其他信息。

It connects to the IP address supplied without any problems, but all I get back in the above mentioned HTTP error code 400. I am not sure if I was supposed to include a HTTP version after my POST or and Content-Length or any other information.

推荐答案

原来的问题已经回答了，但只是针对通过谷歌路过的人参考;这里是一个更完整的例子，如何发布数据与一个Arduino web服务器：

The original question is already answered, but just for reference for people passing by via Google; here is a more complete example how to post data to a webserver with an Arduino:

IPAddress server(10,0,0,138);
String PostData = "someDataToPost";

if (client.connect(server, 80)) {
  client.println("POST /Api/AddParking/3 HTTP/1.1");
  client.println("Host: 10.0.0.138");
  client.println("User-Agent: Arduino/1.0");
  client.println("Connection: close");
  client.print("Content-Length: ");
  client.println(PostData.length());
  client.println();
  client.println(PostData);
}
