您如何从ac＃客户端发送补丁请求？

Question

I have a powershell script that does this :

    $uri = "$($tfsUri)/$($teamproject)/_apis/build/builds/$($buildID)?api-version=2.0"
    $data = @{keepForever = $keepForever} | ConvertTo-Json
    $response = $webclient.UploadString($uri,"PATCH", $data) 

I'm trying to rewrite this in C#, using a Webclient.

WebClient client = new WebClient();
client.Encoding = System.Text.Encoding.UTF8;
string reply = client.UploadString(url, "keepForever = true");
Console.WriteLine(reply);

But I get : The remote server returned an error: (401) Unauthorized.

This is TFS 2015 VNext, if that helps.

Answer 1

You are missing the METHOD in your call to UploadString .

string reply = client.UploadString(url, "keepForever = true");

should be:

string reply = client.UploadString(url, "PATCH", "keepForever = true");

A 401 is unauthorised, so also see if there is a step before in your Powershell where you are logging in or joining a session, you would need to replicate that in your C#.

Answer 2

In order to send a PATCH request you can use WebClient.UploadData .

string data = "keepForever = true";
WebClient client = new WebClient();
client.Encoding = System.Text.Encoding.UTF8;
string reply = client.UploadData(url, "PATCH", System.Text.Encoding.UTF8.GetBytes(data));
Console.WriteLine(reply);
