Question

我想从网址

获取数据

http://cloud.traffy.in.th/apis/apitraffy.php?api=get_bus_line_info&appid=51248f9a&bus_line={bus_line}

来自edittext的

和{bus_line}

示例

http://cloud.traffy.in.th/apis/apitraffy.php?api=get_bus_line_info&appid=51248f9a&bus_line=17

但我尝试通过retrofit2获取数据，现在我收到错误

D / Resultttt：Not Found

Bus.java

公共班巴士{

  @SerializedName("bus_line")
  @Expose
  private String busLine;
  @SerializedName("start")
  @Expose
  private String start;
  @SerializedName("end")
  @Expose
  private String end;
  @SerializedName("vehicle_type")
  @Expose
  private String vehicleType;
  @SerializedName("owner")
  @Expose
  private String owner;
  @SerializedName("route_type")
  @Expose
  private String routeType;
  @SerializedName("bus_line_id")
  @Expose
  private String busLineId;

  public String getBusLine() {
    return busLine;
  }

  public void setBusLine(String busLine) {
    this.busLine = busLine;
  }


  ....

}

Getbus.java

      public interface Getbus {
  @GET("apis/apitraffy.php")
  Call<Bus> select(@Query("api") String api, @Query("appid") String appId, @Query("bus_line") String bus_line);
}

和MainActivity.java

    public class MainActivity extends AppCompatActivity {

      Button button;
      EditText editText;
      TextView textView;
      private Getbus getbus;
      private String BASE_URL = "http://cloud.traffy.in.th/";
      private String TAG = "fong";

      @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        button = (Button) findViewById(R.id.button);
        editText = (EditText) findViewById(R.id.editText);
        textView = (TextView) findViewById(R.id.textView);


        Retrofit retrofit = new Retrofit.Builder()
                            .baseUrl(BASE_URL)
                            .addConverterFactory(GsonConverterFactory.create())
                            .build();

        getbus = retrofit.create(Getbus.class);

        button.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View view) {

            String store = editText.getText().toString(); //////store=17
            loadBus(store); 



          }
        });
      }

      private void loadBus(String bus_line){

    Call<Bus> call = getbus.select(api, appId, bus_line);
    call.enqueue(new Callback<Bus>() {
      @Override
      public void onResponse(Call<Bus> call, Response<Bus> response) {
       // displayBus(response.body());
        if (response.isSuccessful()){
          Log.d("Result", response.body().getBusLine());
        }else
        {
          Log.d("Resultttt",response.message());
        }

      }

      @Override
      public void onFailure(Call<Bus> call, Throwable t) {
        Log.e(TAG,"Errorr: " + t.getMessage());
      }
    });
  }

  private void displayBus(Bus showBus){
    if(showBus != null){
      String data = showBus.getBusLine();
      textView.setText(data);
    }else {
      textView.setText("No Busline");
    }
  }
}

我想从edittext获取文本，并将{bus_line}替换为show data

感谢您的帮助！

错误消息告诉您确切的错误。你的界面应该更像这样：

public interface Getbus {
  @GET("apis/apitraffy.php")
  Call<Bus> select(@Query("api") String api, @Query("appid") String appId, @Query("bus_line") String bus_line);
}

如果您不想每次都传递api和app id，请查看请求拦截器。

对于日志记录，请将其添加到build.gradle依赖项：compile 'com.squareup.okhttp3:logging-interceptor:3.6.0'

以及构建改造的地方：

final OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();

            HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
            loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
            clientBuilder.addInterceptor(loggingInterceptor);

final OkHttpClient client = clientBuilder.build();
Retrofit retrofit = retrofitBuilder
                .baseUrl(params.url)
                .client(client)
                .build();

错误通过retrofit2获取数据
