用CI作为android的server
我做了一个手机端，实现简单的登陆注册，采用通过json通信，参照http://www.androidhive.info/2012/01/android-login-and-registration-with-php-mysql-and-sqlite/ 不过我用CI作为server端。可是在执行httpClient.execute(httpPost);总是报一堆错误，不用CI作为server就正常~ 请问有人了解这是什么原因吗？是不是ci的url问题？能把问题 贴出来么，这么说有个毛线用，再者这些问题跟框架有什么关系。。。。。。。。 先用get測看看吧!

java部分代码，运行到HttpResponse httpResponse = httpClient.execute(httpPost);就出错了

你有没有做rewrite？
没有的话就要带上index.php
http://www.zhaoxi.me/auth/regist/app_login这个打开就是not found

rewrite了~
加Q349703434吧
http://www.zhaoxi.me/auth/regist/app_login
这个应该要做路由吧，默认的controller是神马 gogogo1027 发表于 2013-7-2 14:38 static/image/common/back.gif

不好意思，刚才代码贴错了，是login/app_login
不过这个问题不影响，原来在regist路径下也是不行~
你先检查一下你返回的json数据是什么。 查看一下url正確性,
還有檢查一下環境設定,
比如檢查能不能跨網域請求有沒有關閉.
在android端請輸出所有錯誤碼,
這樣可以更清礎錯誤的原因.
