.NET:发送带有数据和读取响应的 POST 的最简单方法 [英] .NET: Simplest way to send POST with data and read response
本文介绍了.NET:发送带有数据和读取响应的 POST 的最简单方法的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
令我惊讶的是,据我所知,在 .NET BCL 中,我几乎不能做任何像这样简单的事情:
To my surprise, I can't do anything nearly as simple as this, from what I can tell, in the .NET BCL:
byte[] response = Http.Post
(
url: "http://dork.com/service",
contentType: "application/x-www-form-urlencoded",
contentLength: 32,
content: "home=Cosby&favorite+flavor=flies"
);
上面的这个假设代码使用数据创建一个 HTTP POST,并从静态类 Http
上的 Post
方法返回响应.
This hypothetical code above makes an HTTP POST, with data, and returns the response from a Post
method on a static class Http
.
既然我们没有这么简单的东西,那么下一个最佳解决方案是什么?
Since we're left without something this easy, what's the next best solution?
如何发送带有数据的 HTTP POST 并获取响应的内容?
How do I send an HTTP POST with data AND get the response's content?
推荐答案
using (WebClient client = new WebClient())
{
byte[] response =
client.UploadValues("http://dork.com/service", new NameValueCollection()
{
{ "home", "Cosby" },
{ "favorite+flavor", "flies" }
});
string result = System.Text.Encoding.UTF8.GetString(response);
}
您将需要这些包括:
using System;
using System.Collections.Specialized;
using System.Net;
如果您坚持使用静态方法/类:
If you're insistent on using a static method/class:
public static class Http
{
public static byte[] Post(string uri, NameValueCollection pairs)
{
byte[] response = null;
using (WebClient client = new WebClient())
{
response = client.UploadValues(uri, pairs);
}
return response;
}
}
那么简单:
var response = Http.Post("http://dork.com/service", new NameValueCollection() {
{ "home", "Cosby" },
{ "favorite+flavor", "flies" }
});
