C#如何使用HttpWebRequest获取JSON字符串

有人帮我从gitlab网站获取JSON.我编写了我的代码但是当我编译代码时,我The remote server returned an error: (401) Unauthorized.在控制台应用程序(C#)中收到了异常.

在我的浏览器中,当我在浏览器中登录时,我运行相同的URL,我可以获得JSON字符串.如果我从浏览器退出后运行相同的URL,我会{"message":"401 Unauthorized"}在浏览器中收到消息.

由于同样的例外,我认为我没有将用户名和凭证传递给我HttpWebRequest.

我在线上得到了例外 HttpWebResponse response = request.GetResponse() as HttpWebResponse;

我的代码:

            string URL = "http://gitlab.company.com/api/v3/users?per_page=100&page=1";  
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
            request.ContentType = "application/json; charset=utf-8";
            request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("userName:passWord"));
            request.PreAuthenticate = true;
            HttpWebResponse response = request.GetResponse() as HttpWebResponse;
            using (Stream responseStream = response.GetResponseStream())
            {
                StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
                Console.WriteLine(reader.ReadToEnd());
            }

我的问题:

我犯了什么错误？

我知道我必须使用GET动词来获取API中的数据,但我不知道我必须在哪里使用GET动词？

提前致谢.

在您的请求中使用编码,凭证需要在ISO-8859-1中编码

        string URL = "http://gitlab.company.com/api/v3/users?per_page=100&page=1";
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
        request.ContentType = "application/json; charset=utf-8";
        request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.GetEncoding("ISO-8859-1").GetBytes("username:password"));
        request.PreAuthenticate = true;
        HttpWebResponse response = request.GetResponse() as HttpWebResponse;
        using (Stream responseStream = response.GetResponseStream())
        {
            StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
            Console.WriteLine(reader.ReadToEnd());
        }

如果这不起作用,请删除标题行并将其替换为以下内容:

request.Credentials = new NetworkCredential("username", "password");
