c# - 从 azure devops 服务器下载文件将错误数据写入文件
问题描述
我正在尝试使用 API 从 azure devops 服务器下载 SQL 文件，但是带有注销链接的 html 页面源代码被复制到文件中。
C# 代码
var personalaccesstoken = "wwwwwwwwwwwwwwwwwwy47b7ugkz32bubi64bw7fqdyfpa";
var url = $"https://dev.azure.com/OrgTest/ABCProject/_apis/git/repositories/e9e2f082-99999iii-dummy-869b0bcc737a/items?path=/Versiondata/Datfile/ABC.sql&includeContent=true&api-version=5.1";
var request = (HttpWebRequest)WebRequest.Create(url);
request.UserAgent = "VSTS-Get";
request.Headers.Set(HttpRequestHeader.Authorization, "Bearer " + personalaccesstoken);
request.ContentType = "application/json";
request.Method = "GET";
request.AllowAutoRedirect = true;
var response = (HttpWebResponse)request.GetResponse();
using (var responseStream = response.GetResponseStream())
{
using (var filestream = File.Create(System.IO.Path.Combine("D:\\testFolder\\", "ABC.sql")))
{
responseStream.CopyTo(filestream);
}
}
不幸的是，我在文件中低于 html 内容
内容输出文件

我尝试从下行下载。我面临同样的问题。我们是否应该在 Azure DevOps 服务器中为开发中的应用程序添加授权？
解决方案
最后我找到了解决这个问题的方法。这里我们尝试使用个人访问令牌（PAT）。为了使用 PAT 进行身份验证，我们必须使用授权"Basic"而不是"Bearer".More over 而不是单独将 PAT 添加到我们拥有的请求标头中使用用户名和 PAT 的组合。说用户名的 base-64 编码字符串：PAT。
所需的代码更改
var personalaccesstoken = "wwwwwwwwwwwwwwwwwwy47b7ugkz32bubi64bw7fqdyfpa";
var base64Creds = Convert.ToBase64String(Encoding.ASCII.GetBytes("SPabbbal@ABCTech.com:"+ personalaccesstoken));
request.Headers.Set(HttpRequestHeader.Authorization, "Basic " + base64Creds);
谢谢你的支持。
