Question

我正在发出GET请求：

public interface CheckUserInDBRequest {
@GET("api/checkUserInDB.php")
Call<ResponseBody> searchForUser(
        @Query("login") String login,
        @Query("pass") String pass
);
}

我的答案是真的|| json中的false，根据数据库中是否有用户。

Retrofit.Builder builder = new Retrofit.Builder().baseUrl("https://kurusa.zhecky.net/").addConverterFactory(GsonConverterFactory.create());

Retrofit retrofit = builder.build();

CheckUserInDBRequest client = retrofit.create(CheckUserInDBRequest.class);
Call<ResponseBody> call = client.searchForUser (
        UserLogin.getText().toString(),
        UserPass.getText().toString()
);

call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(@NonNull Call<ResponseBody> call, @NonNull Response<ResponseBody> response) {

        Toast.makeText(MainActivity.this, response.body().toString(), Toast.LENGTH_LONG).show();
    }

    @Override
    public void onFailure(@NonNull Call<ResponseBody> call, @NonNull Throwable t) {

        Toast.makeText(MainActivity.this, "no ", Toast.LENGTH_SHORT).show();
    }
});

以下是okHttp3的输出。我不明白如何得到正常答案。

首先，创建一个代表JSON对象

的类

public class UserResult {
    public boolean isSet;
}

以这种方式重组Retrofit来电

@GET("api/checkUserInDB.php")
Call<UserResult> searchForUser(
        @Query("login") String login,
        @Query("pass") String pass
);

然后在你的代码中：

call.enqueue(new Callback<UserResult>() {
    @Override
    public void onResponse(@NonNull Call<UserResult> call, @NonNull Response<UserResult> response) {
        if (response.isSuccesfull()) {
            UserResult result = response.body();
            //use the value result.isSet where you need it
        } else {
            //something is broken
        }
    }

    @Override
    public void onFailure(@NonNull Call<UserResult> call, @NonNull Throwable t) {

        Toast.makeText(MainActivity.this, "no ", Toast.LENGTH_SHORT).show();
    }
});
