我尝试了一周没有找到解决方案
总是会出错
HttpUrlConnection
状态代码500,有时状态代码400
我试试
JsonCallBack
但没有数据回复
myurl正常使用浏览器并获取数据
但是在android中我的代码没什么错误
我的代码:
public class AcceptOrder extends AppCompatActivity {
EditText Names;
EditText No;
EditText Adres;
AQuery aQuery;
Handler handler;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_accept_order);
Names = (EditText) findViewById(R.id.name);
No = (EditText) findViewById(R.id.phoneNo);
Adres = (EditText) findViewById(R.id.adress);
aQuery = new AQuery(this);
handler = new Handler();
// final LocationManager manager = (LocationManager) getSystemService(LOCATION_SERVICE);
// if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
// buildAlertMessageNoGps();}
}
public void FinishedOrder(View view) {
String UserNAme = Names.getText().toString();
String PhoneNo = No.getText().toString();
String Addr = Adres.getText().toString();
if((UserNAme.length()<2 )) {
Operations.DisplayMessage(this, getResources().getString(R.string.AddAllinfo));
return;
} else {
UserSetting.url1=UserSetting.ServerURL+"Sallyer.asmx/Test?UserName="+ UserNAme+
"&UserPhone="+PhoneNo+
"&addres="+Addr+"&TotalPrice="
+UserSetting.TotalPrice;
new MyAsyncTaskgetNews().execute();
}
}

和我的Url这个例子 并在浏览器中工作

尝试这样使用这将解决您的问题
public String getimageurl(String id){
String url="http://www.abc1234.com/wp-json/wp/v2/media/"+id;
RequestQueue requestqueue = Volley.newRequestQueue(getApplicationContext());
StringRequest stringrequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
imageurl=response;
JSONObject jsonObject = new JSONObject(response);
String j = jsonObject.getString("guid");
jsonObject = new JSONObject(j);
imageurl =jsonObject.getString("rendered");
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
requestqueue.add(stringrequest);
return imageurl;
}

你可以使用Android的Volley来请求url并使用GSON库解析它。这是一种更有效的方法。
