Question

我正在尝试使用Retrofit2向我们的AWS lambda服务器（https://）发送请求，但服务器无法读取我传递的参数。但是，当我尝试使用指向我们本地网络（http://）的相同代码时，它可以工作。以下是我的代码，请帮助。

Gradle Dependencies：

compile "com.squareup.retrofit2:retrofit:2.3.0"
compile "com.squareup.retrofit2:converter-gson:2.3.0"
compile 'com.squareup.okhttp3:logging-interceptor:3.10.0'

请求类：

public class LoginRequest {

  @SerializedName("login_credential")
  private String credential;
  @SerializedName("password")
  private String password;

  public LoginRequest(String credential, String password) {
    this.credential = credential;
    this.password = password;
  }
}

改造初始化：

public class ServerClient {

    public static Login getClient() {
        HttpLoggingInterceptor logger = new HttpLoggingInterceptor();
        logger.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder()
                .addInterceptor(logger)
                .build();

        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("https://my.server.ap-southeast-1.amazonaws.com/dev/")
                .client(client)
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        return retrofit.create(Login.class);
    }

    public interface Login {
        @Headers("Accept: application/json")
        @POST("login")
        Call<LoginResponse> login(@Body LoginRequest request);
    }

}

我触发请求的方式：

Call<LoginResponse> call = ServerClient.getClient().login(new LoginRequest(email, password));
    call.enqueue(new Callback<LoginResponse>() {
        @Override
        public void onResponse(@NonNull Call<LoginResponse> call, @NonNull Response<LoginResponse> response) {
            if (response.body() != null) {
                Log.e("response", "success");
            }
        }

        @Override
        public void onFailure(@NonNull Call<LoginResponse> call, @NonNull Throwable t) {
            Log.e("response", "failed");
        }
    });

这是日志：

Answer 1

通常还会添加@Expose参数，如：

@Expose
@SerializedName("error")
private ApiErrorNew error;

@Expose
@SerializedName("Status")
private String status;

添加相同并尝试。

Answer 2

我通过在POST请求中添加一些标题来修复此问题：

module.o

服务器无法使用Retrofit2读取HTTPS POST请求参数
