从php获取回显消息
我正在使用httppost方法向php发送3个参数。这3个参数在mysql查询中用于检索特定记录。 但是，我的json.getInt（）指向null。有没有办法让我收到回音信息从php获取回显消息,php,android,json,Php,Android,Json,我正在使用httppost方法向php发送3个参数。这3个参数在mysql查询中用于检索特定记录。 但是，我的json.getInt（）指向null。有没有办法让我收到回音信息 protected String doInBackground(String... args) { // updating UI from Background Thread List<NameValuePair> params =

此代码是否在浏览器中回显？此外，还可以提供此方法jParser.makeHttpRequest（）。这个json文件位于哪里？您的本地主机？是的，它在浏览器中回显，这是回显消息。{“records”：[{“booking_ID”：“15”，“booking_Title”：“abc”}]，“success”：1}是的，在localhost中。我已经上传了jparser.makeHttpRequest（）@internal_class7你是在模拟器上还是在手机上进行测试？发布你的日志，它看起来jsonobject是空的。我在手机上进行测试，但是应用程序会因为空指针而停止。我尝试在高级Rest客户机上运行php，效果很好@我把同样的WiFi也放进去了。在我的手机上，所有其他从php插入或检索记录的功能都在工作，只是这个方法我无法读取响应。
