Question

我想从我的代码或api中找出错误。

这是我的API类别：

      import retrofit2.Call;
      import retrofit2.http.Body;
      import retrofit2.http.POST;

      public interface Api {


          @POST("/api/Database/NewLocation")
          Call<MapDetails> mapDetailLocation(@Body MapDetails mapDetails);

          @POST("/api/Registration/RegisterDevice")
          Call<RegisterDetails> registerDetails(@Body RegisterDetails                     
           registerAllDetails);

      }

SETTER CLASS：

      import com.google.gson.annotations.SerializedName;

      public class MapDetails {
          @SerializedName("SerialNumber")
          private String serialNumber;
          @SerializedName("Coordinate1")
          private String coordinate1;
          @SerializedName("Coordinate2")
          private String coordinate2;
          @SerializedName("DateTime")
          private String dateTime;
          @SerializedName("Speed")
          private String speed;
          @SerializedName("Port")
          private Integer Port;



          public MapDetails(String serialNumber, String coordinate1, String           
           coordinate2,
                            String dateTime, String speed, Integer port) {
              this.serialNumber = serialNumber;
              this.coordinate1 = coordinate1;
              this.coordinate2 = coordinate2;
              this.dateTime = dateTime;
              this.speed = speed;
              Port = port;
          }

          public String getSerialNumber() {
              return serialNumber;
          }

          public void setSerialNumber(String serialNumber) {
              this.serialNumber = serialNumber;
          }

          public String getCoordinate1() {
              return coordinate1;
          }

          public void setCoordinate1(String coordinate1) {
              this.coordinate1 = coordinate1;
          }

          public String getCoordinate2() {
              return coordinate2;
          }

          public void setCoordinate2(String coordinate2) {
              this.coordinate2 = coordinate2;
          }

          public String getDateTime() {
              return dateTime;
          }

          public void setDateTime(String dateTime) {
              this.dateTime = dateTime;
          }

          public String getSpeed() {
              return speed;
          }

          public void setSpeed(String speed) {
              this.speed = speed;
          }

          public Integer getPort() {
              return Port;
          }

                    public void setPort(Integer port) {
              Port = port;
          }
      }

活动类别：

                    MapDetails mapDetails = new MapDetails("1807200005", 
                    lat,lon, currentDateTimeString, "0", 9090);
                    setLocation(mapDetails);



                   private void setLocation(MapDetails mapDetails) {
                      initializeRetrofit(mapDetails);
                     }

                private void initializeRetrofit(MapDetails mapDetails) {
                    Retrofit.Builder builder = new Retrofit.Builder()
                            .baseUrl("http://undefine.apisecure.data[![enter image description here][1]][1]")
                      .addConverterFactory(GsonConverterFactory.create());

                    Retrofit retrofit = builder.build();

                    Api locate = retrofit.create(Api.class);

                    SetMapLocationApiCaller(locate, mapDetails);


                }

                private void SetMapLocationApiCaller(Api locate, MapDetails 
                mapDetails) {

                    Call<MapDetails> call =                      
                    locate.mapDetailLocation(mapDetails);
                    executeCallAsynchronously(call);
                }

                private void executeCallAsynchronously(Call call) {
                    call.enqueue(new Callback<MapDetails>() {
                        @Override
                        public void onResponse(Call<MapDetails> call, 
                         Response<MapDetails> response) {

                            Snackbar.make(view,""+ response, 
                                    Snackbar.LENGTH_INDEFINITE)
                                    .setAction("Action", null).show();
                        }

                        @Override
                        public void onFailure(Call call, Throwable t) {
                            Snackbar.make(view, ""+t.getMessage(), 
                                      Snackbar.LENGTH_INDEFINITE)
                                    .setAction("Action", null).show();

                        }
                    });


                }

在我的应用上，这是我的应用上的响应：

，但未添加到我的SQL中。但是，如果使用insomia，它将把我创建的数据发送到数据库。

此数据是通过insomia插入的，而不是通过移动设备插入的。

您几乎可以找到解决方案。但是，在将参数传递给API请求时，您几乎没有犯错。

从Insomia应用程序的屏幕截图中可以看到，该API需要JSONArray作为参数，但是您正在发送JSONObject。

示例JSON参数

Api.java

根据上述JSON结构，您需要将import retrofit2.Call; import retrofit2.http.Body; import retrofit2.http.POST; import java.util.List; // add import public interface Api { @POST("/api/Database/NewLocation") Call < MapDetails > mapDetailLocation(@Body List<MapDetails> mapDetails); // ^^^^ changes here @POST("/api/Registration/RegisterDevice") Call < RegisterDetails > registerDetails(@Body RegisterDetails registerAllDetails); }类更改为以下内容：

List<MapDetails>

在mapDetailLocation()方法参数中添加//...... // part of the code MapDetails mapDetails = new MapDetails("1807200005", lat, lon, currentDateTimeString, "0", 9090); List<MapDetails> data = new ArrayList<>(); data.add(mapDetails); Retrofit.Builder builder = new Retrofit.Builder() .baseUrl("<BASE_URL>") // change base URL .addConverterFactory(GsonConverterFactory.create()); Retrofit retrofit = builder.build(); Api locate = retrofit.create(Api.class); Call<MapDetails> call = locate.mapDetailLocation(data); // NOTICE THE CHANGES IN PARAMETER call.enqueue(new Callback<MapDetails>() { @Override public void onResponse(Call<MapDetails> call, Response<MapDetails> response) { // do whatever you want } @Override public void onFailure(Call call, Throwable t) { // log the error message } });。

在Activity或Fragment中使用上述方法，如下所示：

MapDetails

注意：请根据您的要求更改基本URL。

编辑：

将“活动”中的方法参数从List<MapDetails>更改为// prepare data MapDetails data = new MapDetails("1807200005", lat, lon, currentDateTimeString, "0", 9090); // add it to ArrayList List<MapDetails> mapDetails = new ArrayList<>(); mapDetails.add(data); // pass it as an argument private void setLocation(List<MapDetails> mapDetails) { initializeRetrofit(mapDetails); }

initializeRetrofit()

更改private void initializeRetrofit(List<MapDetails> mapDetails) { Retrofit.Builder builder = new Retrofit.Builder() .baseUrl("<BASE_URL>") // change base URL .addConverterFactory(GsonConverterFactory.create()); Retrofit retrofit = builder.build(); Api locate = retrofit.create(Api.class); SetMapLocationApiCaller(locate, mapDetails); }中的方法参数

private void SetMapLocationApiCaller(Api locate, List<MapDetails> mapDetails) {
    Call<MapDetails> call = locate.mapDetailLocation(mapDetails);
    executeCallAsynchronously(call);
}

再次更改方法参数

此改装代码可能出现什么错误？我无法理解我的API和MOBILE的联系
