Question

当我在解析服务器响应时尝试获取名称时，我得到null。您能帮我获取数据，即姓名，电子邮件和keyskills.name吗？

JSON响应在这里。

这是我的pojo课

public class FreeLancer {
    private List<FreeLancerProfile> freelancer;

    // Constructors, getters and setters are removed for convenience
}

这是我的自由职业者个人资料

public class FreeLancerProfile {
    private int id;

我的Pojo课堂上的关键技能

public class KeySkill {

    Call<FreeLancerProfile> freeLancerMain(
            @Path(value = "fullUrl", encoded = true) String fullUrl,
            @Header("Authorization") String token

    @GET("{fullUrl}/profile")
    Call<KeySkill> keySkillsMain(
            @Path(value = "fullUrl", encoded = true) String fullUrl,
            @Header("Authorization") String token

}

我的主要活动

String BASE_URL = "http://74.207.233.160/api/v1/freelancers/";

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

Retrofit retrofit = builder.build();
final FreeLancerMainApi api = retrofit.create(FreeLancerMainApi.class);

Call<FreeLancerProfile> call = api.freeLancerMain(freelancer_id, token);

call.enqueue(new Callback<FreeLancerProfile>() {
    @Override
    public void onResponse(Call<FreeLancerProfile> call, Response<FreeLancerProfile> response) {
        if (response.code() == 200)
        {
            name = response.body().getName();
            email = response.body().getEmail();
            contactNumber = response.body().getContact_number();
            Toast.makeText(FreelancerActivity.this, name, Toast.LENGTH_SHORT).show();
        }
        else {
        }
    }

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

    }
});

Call<KeySkill> call1 = api.keySkillsMain(freelancer_id, token);
call1.enqueue(new Callback<KeySkill>() {
    @Override
    public void onResponse(Call<KeySkill> call, Response<KeySkill> response) {
        if (response.code() == 200){
            skills = response.body().getName();
        }else {

        }
    }

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

    }
});

freeLancerMainName.setText(name);
freeLancerMainEmail.setText(email);
freeLancerContactNumber.setText(contactNumber);
freeLancerKeySkills.setText(skills);

执行此代码时，我得到的响应为空。请帮助并提前致谢！

Answer 1

正如我从响应中看到的那样，它没有返回数组或列表。但是，据您从代码中了解到的那样，您期望将响应解析为一个列表。

Freelancer pojo应该如下所示。

public class FreeLancer {
    public FreeLancerProfile freelancer;
}

如果其他一切正常，则应该可以正常工作。

更新：

响应应绑定到FreeLancer类，而不是FreeLancerProfile类。我已经显示了一个示例，可能会有所帮助。请检查。

public void onResponse(Call<FreeLancer> call, Response<FreeLancer> response) {
    if (response.code() == 200) {
        FreeLancer freelancer = response.body();

        name = freelancer.getName();
        email = freelancer.getEmail();
        // Others ... 
    }
}

在FreelancerProfile pojo中，还需要从List和key_skills中删除other_skills。这些也不是列表。

private KeySkill key_skills;
private OtherSkill other_skills;

当数据如下所示时，如何从改造中获取数据
