如何使用HttpClient进行身份验证发布
如何使用HttpClient进行身份验证发布
提问于 2015-06-16 12:36:42
我正在尝试使用HttpClient在C#中执行以下curl (对我有效)。
curl -X POST http://www.somehosturl.com \
-u <client-id>:<client-secret> \
-d 'grant_type=password' \
-d 'username=<email>' \
-d 'password=<password>' \
-d 'scope=allC#代码：
HttpClientHandler handler = new HttpClientHandler { Credentials = new
System.Net.NetworkCredential ("my_client_id", "my_client_secret")
};
try
{
using(var httpClient = new HttpClient(handler))
{
var activationUrl = "www.somehosturl.com";
var postData = "grant_type=password&username=myemail@myemail.com&password=mypass&scope=all";
var content = new StringContent(postData, Encoding.UTF8, "application/x-www-form-urlencoded");
var response = await httpClient.PostAsync(activationUrl, content);
if(!response.IsSuccessStatusCode)
return null;
var result = await response.Content.ReadAsStringAsync();
return result;
}
}
catch(Exception)
{
return null;
}在执行时，就会崩溃，甚至不会捕获异常
通常情况下，我可以很好地获取和发布，但让我感到困惑的是如何设置身份验证内容(client-id和client-secret)

首先，你必须用你的<clientid>和<clientsecret>设置Authorization-Header。
您应该使用FormUrlEncodedContent而不是StringContent，如下所示：
var client = new HttpClient();
client.BaseAddress = new Uri("http://myserver");
var request = new HttpRequestMessage(HttpMethod.Post, "/path");
var byteArray = new UTF8Encoding().GetBytes("<clientid>:<clientsecret>");
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));
var formData = new List<KeyValuePair<string, string>>();
formData.Add(new KeyValuePair<string, string>("grant_type", "password"));
formData.Add(new KeyValuePair<string, string>("username", "<email>"));
formData.Add(new KeyValuePair<string, string>("password", "<password>"));
formData.Add(new KeyValuePair<string, string>("scope", "all"));
request.Content = new FormUrlEncodedContent(formData);
var response = await client.SendAsync(request);Stack Overflow用户

尝试将凭据直接放入HttpClient的headers属性中。
using (var client = new HttpClient()) {
var byteArray = Encoding.ASCII.GetBytes("my_client_id:my_client_secret");
var header = new AuthenticationHeaderValue("Basic",Convert.ToBase64String(byteArray));
client.DefaultRequestHeaders.Authorization = header;
return await client.GetStringAsync(uri);

请参阅BasicAuthenticationHeaderValue
httpClient.DefaultRequestHeaders.Authorization
= new BasicAuthenticationHeaderValue("login", "password");页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
