请求access_token时遇到21323错误 报错信息： error":"invalid_request","error_code":21323,"request":"/oauth2/access_token","error_uri":"/oauth2/access_token","error_description":"miss client id or secret“ 解决方案: 参照文档：http://open.weibo.com/wiki/OAuth2/access_token，这里写的是POST提交，但是这里的post的URL为 https://api.weibo.com/oauth2/access_token?client_id=client_id&client_secret=client_secret&grant_type=authorization_code&code=code&redirect_uri=redirect_uri 提交的data应该为空 参考代码： // 获取access_token String url = "https://api.weibo.com/oauth2/access_token?client_id=" + OtherConfig.WEIBO_APP_ID+ "&client_secret=" + OtherConfig.WEIBO_APP_SECRET+ "&grant_type=authorization_code&code="+code+"&redirect_uri="+OtherConfig.WEIBO_BACK_URI; HttpPost httpPost = new HttpPost(url); JSONObject json = new JSONObject(); String response = HttpClientUtils.doPost(httpPost, json.toJSONString()); 成功解决，这里的data必须为空
