我卡在这了，不明白问题出在哪里。API在Postman中测试成功，但在我的应用程序中失败。
我的代码如下:
public void posting() {
String title = titleArticle.getText().toString();
// String category = spinnerCat.getCount();
String content = contentArticle.getText().toString();
// Instantiate Http Request Param Object
RequestParams params = new RequestParams();
params.put("title", title);
params.put("content", content);
// Invoke RESTful Web Service with Http parameters
invokeWS(params);
}
/**
* Method that performs RESTful webservice invocations
*
* @param params
*/
public void invokeWS(RequestParams params) {
// Show Progress Dialog
prgDialog.show();
AsyncHttpClient client = new AsyncHttpClient();
client.post("http://openetizen.com/api/v1/articles", params, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
// Hide Progress Dialog
prgDialog.hide();
try {
JSONObject obj = new JSONObject(new String(responseBody));
if (obj.getString("status").equalsIgnoreCase("success")) {
Toast.makeText(getApplicationContext(), "Artikel berhasil diunggah!", Toast.LENGTH_LONG).show();
Intent i = new Intent(PostingActivity.this, MainActivity.class);
startActivity(i);
} else {
errorMsg.setText(obj.getString("error_msg"));
Toast.makeText(getApplicationContext(), obj.getString("error_msg"), Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
// TODO Auto-generated catch block
Toast.makeText(getApplicationContext(), "Error Occured [Server's JSON response might be invalid]!", Toast.LENGTH_LONG).show();
e.printStackTrace();
Log.e("ERROR", "Response");
}
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
// Hide Progress Dialog
prgDialog.hide();
// When Http response code is '404'
if (statusCode == 404) {
Toast.makeText(getApplicationContext(), "Requested resource not found", Toast.LENGTH_LONG).show();
}
// When Http response code is '500'
else if (statusCode == 500) {
Toast.makeText(getApplicationContext(), "Something went wrong at server end", Toast.LENGTH_LONG).show();
}
// When Http response code other than 404, 500
else {
Toast.makeText(getApplicationContext(), "Posting failed", Toast.LENGTH_LONG).show();
// Toast.makeText(getApplicationContext(), "Unexpected Error occcured! [Most common Error: Device might not be connected to Internet or remote server is not up and running]", Toast.LENGTH_LONG).show();
}
}
这里发生了一个错误：
else { Toast.makeText(getApplicationContext(), "Posting failed", Toast.LENGTH_LONG).show();
// Toast.makeText(getApplicationContext(), "Unexpected Error occcured! [Most common Error: Device might not be connected to Internet or remote server is not up and running]", Toast.LENGTH_LONG).show();
}
请问我该怎么做来解决这个问题？谢谢。
