我已经达到了对这个问题的挫折限制,所以在这个问题上对我很不满意。)
我正在开发一个新的应用程序,它提供与MailChimp的集成。基本上,它使用户能够轻松地将他们的客户联系信息直接导出到MailChimp帐户(即MailChimp内的特定邮件列表)。 这一切都有效,并且与我的问题有些无关。
为了不要求用户每次都输入MailChimp凭据,我即将实施oauth2授权工作流程,如下所述:http://apidocs.mailchimp.com/oauth2/
它在步骤1-3中工作正常,但第4步正在杀了我.. 这是我第一次与oauth合作,但我似乎理解了基础知识。
这是我的问题:
当我对https://login.mailchimp.com/oauth2/token -URI进行POST调用以获取最终访问令牌时,我不断收到JSON结果中的错误:“invalid_grant”
我检查了请求和响应流,我的网址编译正确。
这是我在控制器中的代码:
(GrantEcoAccess只是授予对另一个应用程序的访问权限 - 其余应该是自我解释的)
public class HomeController : ApplicationController
{
private readonly string authorize_uri = "https://login.mailchimp.com/oauth2/authorize";
private readonly string access_token_uri = "https://login.mailchimp.com/oauth2/token";
private readonly string mailchimp_clientid2 = "xxx";
private readonly string mailchimp_secret2 = "xxx
...
public ActionResult GrantEcoAccess()
{
//if exist: use saved token
var user = (Mailchimp_users)Session["user"];
if (!string.IsNullOrWhiteSpace(user.EcoToken))
return RedirectToAction("GrantMailChimpAccess");
// if !
var url = "https://secure.e-conomic.com/secure/api1/requestaccess.aspx?role=superuser&appId=MailChimp&redirectUrl=http://localhost:18017/Home/IncomingToken";
Redirect(url).ExecuteResult(ControllerContext);
return null;
}
public ActionResult IncomingToken(string token)
{
var user = (Mailchimp_users)Session["user"];
user.EcoToken = token;
EcoSession.DataSession.Refresh(System.Data.Objects.RefreshMode.ClientWins, user);
EcoSession.DataSession.SaveChanges();
return RedirectToAction("GrantMailChimpAccess");
}
public ActionResult GrantMailChimpAccess()
{
//if exist: use saved token
var user = (Mailchimp_users)Session["user"];
if (!string.IsNullOrWhiteSpace(user.MailChimpToken))
return RedirectToAction("Index", "Subscribe");
//if !
var url = string.Format("{0}?response_type=code&client_id={1}&redirect_uri=", authorize_uri, mailchimp_clientid2, "http://127.0.0.1:18017/Home/IncomingMailChimpToken");
Redirect(url).ExecuteResult(ControllerContext);
return null;
}
public ActionResult IncomingMailChimpToken(string code)
{
var url = "https://login.mailchimp.com/oauth2/token?grant_type=authorization_code&client_id=XX&client_secret=XX&code=" + code + "&redirect_uri=http://127.0.0.1:18017/Home/AuthComplete";
//var url = string.Format("?grant_type=authorization_code&client_id={0}&client_secret={1}&code={2}&redirect_uri={3}", mailchimp_clientid, mailchimp_secret, code, Url.Action("AuthComplete"));
Response.Clear();
StringBuilder sb = new StringBuilder();
sb.Append("<html>");
sb.AppendFormat(@"<body onload='document.forms[""form""].submit()'>");
sb.AppendFormat("<form name='form' action='{0}' method='post'>", access_token_uri);
sb.Append("<input type='hidden' name='grant_type' value='authorization_code'>");
sb.AppendFormat("<input type='hidden' name='client_id' value='{0}'>", mailchimp_clientid2);
sb.AppendFormat("<input type='hidden' name='client_secret' value='{0}'>", mailchimp_secret2);
sb.AppendFormat("<input type='hidden' name='code' value='{0}'>", code);
sb.AppendFormat("<input type='hidden' name='redirect_uri' value='{0}'>", "http://127.0.0.1:18017/Home/AuthComplete");
// Other params go here
sb.Append("</form>");
sb.Append("</body>");
sb.Append("</html>");
Response.Write(sb.ToString());
Response.End();
return null;
}
public ActionResult AuthComplete(string access_token, string expires_in, string scope)
{
if (string.IsNullOrWhiteSpace(access_token))
throw new Exception("Could not authorize user with MailChimp");
var user = (Mailchimp_users)Session["user"];
user.MailChimpToken = access_token;
EcoSession.DataSession.Refresh(System.Data.Objects.RefreshMode.ClientWins, user);
EcoSession.DataSession.SaveChanges();
return RedirectToAction("Index", "Subscribe");
}
}
有人可以帮帮我吗? :)
提前谢谢!!
编辑:第4步是杀了我 - 不是第5步;)

你应该使用post发送你的请求参数,如果你使用curl php你会这样做:
$value = http_build_query($params); //params is an array
curl_setopt($ch, CURLOPT_POSTFIELDS, $value);
值应如下所示:
grant_type=authorization_code&client_id=635959587059&client_secret=0da3e7744949e1406b7b250051ee1a95&code=1edf2589e664fd317f6a7ff5f97b42f7&redirect_uri=http%3A%2F%2F192.168.1.8%2Foauth%2Fcomplete.php
请注意,您应该以查询字符串的形式创建一个正文请求,不要发送json,他们找不到你的参数。 如果您在执行此操作后收到无效的授权响应或其他内容,请检查您用于获取第一个代码的重定向uri是否与您要发送的代码完全相同。
另外,对于那些使用PHP的人来说,要匹配mailchimp documentation州使用的内容:
curl_setopt($ch, CURLOPT_USERAGENT, 'oauth2-draft-v10');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));

如果您不想自己实现它,那么有一个很好的包装器,它处理对MailChimp的oAuth2和RESTapi调用。
答案 2 :(得分:0)
步骤4是“您的应用程序必须使用代码向access_token_uri发出带外请求”
这里的要点是“带外”。 您必须构建并发送帖子请求服务器端。 客户端不应该有你的mailchimp_secret
您的IncomingMailChimpToken可能如下所示:
public ActionResult IncomingMailChimpToken(string code)
{
string mcPostData = String.Format(
"grant_type={0}&client_id={1}&client_secret={2}&code={3}&redirect_url={4}",
System.Web.HttpUtility.UrlEncode("authorization_code"),
System.Web.HttpUtility.UrlEncode(mailchimp_clientid2),
System.Web.HttpUtility.UrlEncode(mailchimp_secret2),
System.Web.HttpUtility.UrlEncode(code),
System.Web.HttpUtility.UrlEncode("http://127.0.0.1:18017/Home/AuthComplete")
);
WebRequest request = WebRequest.Create(access_token_uri);
// Set the Method property of the request to POST.
request.Method = "POST";
request.ContentType = "application/json";
byte[] byteArray = Encoding.UTF8.GetBytes(mcPostData);
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Cleanup the streams and the response.
reader.Close ();
dataStream.Close ();
response.Close ();
// parse the json responseFromServer to extract token, expires_in and scope
// and call AuthComplete with these params
}
