我使用slim框架在php中创建了一个restful web服务。其中一个函数返回一个动态创建的多维数组，并将其编码为类似的JSON数组
[{
"hid":100001,
"SubTable":"grpsubs",
"StatTable":"grpstats",
"uid":2,
"Status":"G"
},
{
"hid":100002,
"SubTable":"gtmsubs",
"StatTable":"gtmstats",
"uid":2,
"Status":"R"
}]
在我的android应用程序中，我使用loopj框架来获得像这样的宁静输出
AsyncHttpClient client = new AsyncHttpClient();
client.addHeader("Authorization", key);
client.post("https://mythic-beanbag-106723.appspot.com/v1/mine", params, new AsyncHttpResponseHandler() {
// When the response returned by REST has Http response code '200'
@Override
public void onSuccess(String response) {
// Hide Progress Dialog
hospDialog.hide();
Log.e("Response", response);
try {
JSONArray array = new JSONArray(response);
Log.e("array", String.valueOf(array.length()));
} catch (JSONException e) {
// TODO Auto-generated catch block
Toast.makeText(getApplicationContext(), "Error Occurred [Server's JSON response might be invalid]!", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
使用chrome中的Advanced REST Client，我可以在我的应用程序中看到JSON，但当我尝试在控制台Log.e("Response", response);中输出JSON时，它显示为空数组[]。这段代码适用于我的Login函数，在php中，如果我不使用动态创建的数组，而是使用像array("abc"=>array("def"=>"ghi"), "jkl"=>array("mno"=>"pqr"))这样的静态数组，那么上面的代码确实输出了JSON数组。
更新：
params
RequestParams params = new RequestParams();
params.put("uid", prefs.getInt("uid", 0));
