为什么这个帖子操作失败？ [英] Why is this Post operation failing?

问题描述

根据这个，我的网站API项目，我使用的客户端上的这code：

Based on this, for my Web API project, I'm using this code on the client:

private void AddDepartment()
{
    int onAccountOfWally = 42;
    string moniker = "Billy Bob";
    Cursor.Current = Cursors.WaitCursor;
    try
    {
        string uri = String.Format("http://platypi:28642/api/Departments/{0}/{1}", onAccountOfWally, moniker);
        var webRequest = (HttpWebRequest)WebRequest.Create(uri);
        webRequest.Method = "POST";
        var webResponse = (HttpWebResponse)webRequest.GetResponse();
        if (webResponse.StatusCode != HttpStatusCode.OK)
        {
            MessageBox.Show(string.Format("Failed: {0}", webResponse.StatusCode.ToString()));
        }
    }
    finally
    {
        Cursor.Current = Cursors.Default;
    }
}

我达到我在这一行code的设置断点：

I reach the breakpoint I set on this line of code:

var webResponse = (HttpWebResponse)webRequest.GetResponse();

...但是当我F10在它（或尝试的以F11为它），它失败的远程服务器返回错误（411）需要长度的

...but when I F10 over it (or try to F11 into it), it fails with "The remote server returned an error (411) Length Required"

中的什么的要求，Compilerobot？！？

The length of what is required, Compilerobot?!?

这是我在服务器的存储库类方法：

This is my method in the server's Repository class:

public void Post(Department department)
{
    int maxId = departments.Max(d => d.Id);
    department.Id = maxId + 1;
    departments.Add(department);
}

控制器code是：

The Controller code is:

public void Post(Department department)
{
    deptsRepository.Post(department);
}

我的GET方法做工精细; POST是下一个步骤，但我碰伤我的脚趾至今。

My GET methods are working fine; POST is the next step, but I'm stubbing my toe so far.

推荐答案

你没有发布任何东西。

当你..你需要提供内容的长度。有点像这样的：

When you do.. you need to supply the length of the content. Somewhat like this:

byte[] yourData = new byte[1024]; // example only .. this will be your data

webRequest.ContentLength = yourData.Length; // set Content Length

var requestStream = webRequest.GetRequestStream(); // get stream for request

requestStream.Write(yourData, 0, yourData.Length); // write to request stream
