android 中的 HttpUrlConnection 中的 statusCode 500 或 400

Question

我试了一个星期也没找到解决方法

总是出错

HttpUrlConnection

状态代码 500，有时状态代码 400

我试试

JsonCallBack

但没有返回数据

myurl 与浏览器配合良好并获取数据

但是 android 我的代码没有什么问题

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;

这个例子和我的 Url 在浏览器中运行良好

Answer 1

您可以使用 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。

Answer 2

尝试这样使用这将解决你的问题

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;
}
