你怎么做HTTP Put？ [英] How do you do an HTTP Put?

问题描述

我们这个软件有一个webservices组件。

We have this software that has a webservices component.

现在，这个系统的管理员来找我，希望通过使用以下方法将数据导入系统webservices组件。

Now, the administrator of this system has come to me, wanting to import data into the system by using the webservices component.

所以，我去阅读文档试图解决这个问题，我看到这样的事情：

So, I went to read the documentation to try to figure this thing out and I am seeing things like this:

---

点击此处查看我的内容我在谈论（这在firefox，chrome和safari中看起来最好）

---

该文档提供了相互作用的示例系统使用HTTP动词，如GET，POST，PUT，DELETE。但在我有限的经验中，我从未发送过HTTP PUT或DELETE。

That documentation gives examples of interacting with the system using HTTP verbs such as GET, POST, PUT, DELETE. But in my limited experience, I have never had to send neither an HTTP PUT nor a DELETE.

你是怎么做到的？我已经构建了具有method =post或method =get的HTML表单，并且请求被发送到action属性中指定的任何内容（action =someResource）。但我真的不知道如何处理这个PUT事情。

How do you do it? I have built HTML forms that have method="post" or method="get" and the request is sent to whatever is specified in the action attribute (action="someResource"). But I don't really know what to do with this PUT thing.

如果我不得不猜测，我将不得不构建一个创建某种HTTP的应用程序请求对象并设置它的所有属性，并以某种方式包含我想要PUT到RESOURCE的数据（

我正在尝试使用REST术语，这对我来说是一个非常新的东西

---

）。然后我会用我的编程语言发送请求，等等等等。我只是在猜测这一点。请提供一些帮助！

If I had to guess, I would have to build an application that creates some sort of an HTTP Request object and set all the properties of it and somehow include the data I want to PUT to the RESOURCE (

---

I am trying to use REST terminology, which is something else is very new to me

---

). Then I would send the request using my programming language and blah blah blah. I am just speculating on this. Please offer up some assistance!

我认为我是一名网络开发人员，因为我知道像XHTML，CSS，JavaScript等等，但它开始看起来像我根本不了解网络的基础（HTTP）。

I thought that I was a web developer, since I know things like XHTML, CSS, JavaScript, etc. but it's starting to look like I don't know anything about the foundations of the web at all (HTTP).

PS：我主要用.net编程。因此，.net中的任何示例都非常棒。

PS: I program mostly with .net. So, any examples in .net would be pretty awesome.

推荐答案

这是使用HttpWebRequest的C＃示例：

Here's a C# example using HttpWebRequest:

using System;
using System.IO;
using System.Net;

class Test
{
        static void Main()
        {
                string xml = "<xml>...</xml>";
                byte[] arr = System.Text.Encoding.UTF8.GetBytes(xml);
                HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://localhost/");
                request.Method = "PUT";
                request.ContentType = "text/xml";
                request.ContentLength = arr.Length;
                Stream dataStream = request.GetRequestStream();
                dataStream.Write(arr, 0, arr.Length);
                dataStream.Close();
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                string returnString = response.StatusCode.ToString();
                Console.WriteLine(returnString);
        }
}

更新：现在有了System.Net.Http中的HttpClient类（作为NuGet包提供）这使得这更容易：

Update: there's now an HttpClient class in System.Net.Http (available as a NuGet package) that makes this a bit easier:

using System;
using System.Net.Http;

class Program
{
    static void Main()
    {
        var client = new HttpClient();
        var content = new StringContent("<xml>...</xml>");
        var response = client.PutAsync("http://localhost/", content).Result;
        Console.WriteLine(response.StatusCode);
    }
}
