新浪微博开放平台用code换取accesstoken不成功，错误代码401，请问怎么解决？

我已经获得code了，但是换取accesstoken时，（5个参数我都写了，用AFN发送的POST请求）返回就是
Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: unauthorized (401)"
求高手解决？？？

应该是你的client_ID和client_SERCRET配置错了吧，再次确认一下，注意空格什么的。如果还是不行的话，在微博开放平台中的我的应用的栏的网站信息->测试信息中添加测试账号试试。

希望能帮到你： package weibo4j.examples.timeline; import org.apache.commons.httpclient.header; import org.apache.commons.httpclient.httpclient; import org.apache.commons.httpclient.httpexception; import org.apache.commons.httpclient.methods.postmethod; import org.apache.commons.httpclient.params.httpmethodparams; import weibo4j.oauth; import weibo4j.timeline; import weibo4j.http.accesstoken; import weibo4j.model.weiboexception; import weibo4j.util.weiboconfig; import java.io.ioexception; import java.util.arraylist; import java.util.list; public class sinaweiboul { public static accesstoken gettoken(string username,string password) throws httpexception, ioexception{ string clientid = weiboconfig.getvalue("client_id") ; string redirecturi = weiboconfig.getvalue("redirect_uri") ; string url = weiboconfig.getvalue("authorizeurl"); postmethod postmethod = new postmethod(url); //应用的app key postmethod.addparameter("client_id",clientid); //应用的重定向页面 postmethod.addparameter("redirect_uri",redirecturi); //模拟登录参数 //开发者或测试账号的用户名和密码 postmethod.addparameter("userid", username); postmethod.addparameter("passwd", password); postmethod.addparameter("isloginsina", "0"); postmethod.addparameter("action", "submit"); postmethod.addparameter("response_type","code"); httpmethodparams param = postmethod.getparams(); param.setcontentcharset("utf-8"); //添加头信息 list
