Question

我正在尝试使用受站点保护的WCF webserice。问题是，当我尝试浏览浏览器中的Web服务URL时，它与我提供的凭据一起工作正常。

但是当我尝试以编程方式执行相同操作时，它会抛出错误 - 错误＃401未经授权。

        CookieContainer cookies = null;
        HttpWebRequest request = null;
        HttpWebResponse response = null;
        string responseString = null;
        NameValueCollection tags = null;
        string url = null;
        url = PROTECTED_URL;
        Debug.WriteLine("Step 1: Requesting page @" + url);
        request = (HttpWebRequest)WebRequest.Create(url);
        request.AllowAutoRedirect = false;
        response = (HttpWebResponse)request.GetResponse();
        ShowResponse(response);
        // Step 2: Get the redirection location
        // make sure we have a valid response
        if (response.StatusCode != HttpStatusCode.Found)
        {
            throw new ApplicationException();
        }
        url = response.Headers["Location"];
        // Step 3: Open a connection to the redirect and load the login form, 
        // from this screen we will capture the required form fields.
        Debug.WriteLine("Step 3: Requesting page @" + url);
        request = (HttpWebRequest)WebRequest.Create(url);
        request.AllowAutoRedirect = false;

        try
        {
            response = (HttpWebResponse)request.GetResponse();
        }
        catch (Exception ex)
        {
            string str = ex.Message.ToString();
        }

我的HtTpClient致电WCF。

 public async Task<string> webClient(string method, string uri)
        {
                try
                {

                    var client = new HttpClient();
                    client.Timeout =new TimeSpan(0,0,0,10);
                    client.BaseAddress = new Uri(uri);
                    client.DefaultRequestHeaders.Accept.Add(
                    new MediaTypeWithQualityHeaderValue("application/json"));
                    var response = client.GetAsync(method).Result;

                    string content = await response.Content.ReadAsStringAsync();
                    return content;

                }
                catch (Exception ex)
                {
                    return "Error";
                }
}

Uri是基地址，方法是你的方法名称。

string response = webClient(uri + "/GetSomething/", uri).Result;
