Question

我正在尝试通过翻新添加JSON请求，因为服务器需要JSON请求才能提取数据。

这是我要添加的请求：

{"VALID_FROM":"2018-01-01","VALID_TO":"2019-03-15"}

如果邮递员没有有效载荷，我会收到此消息

INCORRECT_PAYLOAD_DATA ::::::处理消息有效负载时出错元素“ VALID_FROM”丢失

这是我的API接口 SapRestApi.Java

public interface SapRestApi {       
    @Headers("Accept: application/json")
    @GET("/get_users")
    Call<UserList> getUserList();
}

这是我的用户类，在其中找到了获取器和设置器 User.Java

public class User implements POJO {

    @SerializedName("USERNAME")
    private String USERNAME;
    @SerializedName("VALID_FROM")
    private String VALID_FROM;

    @SerializedName("VALID_TO")
    private String VALID_TO;

    public String getUserName() {
        return USERNAME;
    }

    public String getValidFrom() {
        return VALID_FROM;
    }

    public String getValidTo() {
        return VALID_TO;
    }

    public void setUserName(String USERNAME) {
        this.USERNAME = USERNAME;
    }
    public void setValidFrom(String VALID_FROM) {
        this.VALID_FROM = VALID_FROM;
    }

    public void setValidTo(String VALID_TO) {
        this.VALID_TO = VALID_TO;
    }
}
private String USERNAME;

这是我所谓的getUserList（）

public UserList getUserList() {     
    UserList userAccounts = null;

    OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

    Retrofit retrofit = new Retrofit.Builder()
              .baseUrl(server)
              .addConverterFactory(GsonConverterFactory.create())

              .client(httpClient
                      .addInterceptor(new BasicAuthInterceptor(userName, password))
                      .build())

              .build();

    SapRestApi userAPI = retrofit.create(SapRestApi.class);

    Call<UserList> callSync = userAPI.getUserList();



    try {




        Response<UserList> response = callSync.execute();

        System.out.println("Creating Response after Call Sync Execute Method ");
        System.out.println(response.toString());

        userAccounts = response.body();

    } catch (IOException e) {
        e.printStackTrace();
    }

    return userAccounts;
}

每当没有有效负载时，我都会收到错误500。谢谢！
