Question

我正在使用retrofit2 - httpok3以便与Laravel 5.6服务器通信。

我正在尝试＆＃34; GET＆＃34;使用http GET方法的数据帐户。

如果我使用PostMan执行此操作，一切正常。

这是我用来建立android连接的Java类：

界面SvcApi ：

@GET("api/me")
public Call<JSONObject> getMe(@Query("device_id") String device_id);

服务类

public class Svc {


private static SvcApi giftSvc_;



public static synchronized SvcApi initAuth(Context c) {

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }
    DatabaseManager db = new DatabaseManager(c);

    if (db.ExistsUser()) {

        final String token = db.findUser().getToken();

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


        httpClient.addInterceptor(new Interceptor() {
            @Override
            public Response intercept(Chain chain) throws IOException {

                Request original = chain.request();

                Request request = original.newBuilder()
                                .header("Accept", "application/json")
                                .header("Content-Type", "application/json")
                                .header("Authorization", "Bearer " + token)
                                .build();

        });

       Gson gson = new GsonBuilder()
                .setLenient()
                .create();


        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Defaultdata.DEFAULT_IP + ":" + Defaultdata.DEFAULT_PORT + "/")
                .client(httpClient.build())
                .addConverterFactory(GsonConverterFactory.create(gson))
                .build();

        giftSvc_ = retrofit.create(SvcApi.class);

        return giftSvc_;
    } else {
        return null;
    }

}

这是我的Activity类中实现的方法，以便获取数据：

 private void changeActivityTest(){

    svcAth = Svc.initAuth(getApplicationContext());
    Call<JSONObject> call = svcAth.getMe(Settings.Secure.getString(this.getContentResolver(), Settings.Secure.ANDROID_ID));
    call.enqueue(new Callback<JSONObject>() {
        @Override
        public void onResponse(Call<JSONObject> call, Response<JSONObject> response) {

            final JSONObject user = response.body();
            final Response<JSONObject> responsefinal = response;

            Log.e("responsefinal code", responsefinal.code() + "");
            Log.e("responsefinal message", responsefinal.message());
            Log.e("responsefinal headers", responsefinal.headers().toString());
            Log.e("responsef isSuccessful", responsefinal.isSuccessful() + "");
            Log.e("responsefinal raw", responsefinal.raw().toString());
            Log.e("responsefinal body", responsefinal.body().toString());
            if (response.isSuccessful()) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        System.out.println("Success, getMeTest Response body  = " + user.toString());
                        if(responsefinal.code() == 400){

                        }else if(responsefinal.code() == 201 || responsefinal.code() == 200){
                            Log.e("response", user.toString());
                            Log.e("e", responsefinal.toString());
                        }
                    }
                });
            } else {
                try {
                    Log.e("error code :",response.toString() + "");
                    Log.e("error code :",response.code() + "");
                    Log.e("error:",response.message());
                    Log.v("Error ", response.errorBody().string());
                }catch(Exception e){
                    e.printStackTrace();
                }
                if(responsefinal.code() == 500|| responsefinal.code() == 503){
                    Toast.makeText(getApplicationContext(), "O serviço Voado está indisponível neste momento. Por favor, tente mais tarde.", Toast.LENGTH_LONG).show();
                }
            }
        }

        @Override
        public void onFailure(Call<JSONObject> call, Throwable t) {
            t.printStackTrace();
        }
    });

}

正文是一个空的JSONObject {}。

这是我的 LogCat ：

    05-19 18:48:23.268 14659-14659/com.androidsrc.futbolin E/responsefinal body: {}

最后，这是属于这些通信的版本库：

    dependencies {
     [...]
    implementation 'com.google.code.gson:gson:2.8.0'
    implementation 'org.apache:apache:17'
    implementation 'com.google.guava:guava:25.0-android'
    implementation('com.squareup.retrofit2:retrofit:2.3.0') {
        // exclude Retrofit’s OkHttp peer-dependency module and define your own module import
        exclude module: 'okhttp'
    }
    implementation 'com.squareup.okhttp3:okhttp:3.10.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.3.0'
    implementation 'com.squareup.retrofit2:adapter-rxjava2:2.3.0'
    implementation 'io.reactivex:rxandroid:1.2.1'
    implementation 'com.squareup.retrofit2:converter-protobuf:2.3.0'
    implementation 'com.fasterxml.jackson.core:jackson-core:2.9.4'
   [...]

}

与GsonConverterFactory中的Retrofit.Builder()相关，我试图删除gson：

Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Defaultdata.DEFAULT_IP + ":" + Defaultdata.DEFAULT_PORT + "/")
                .client(httpClient.build())
                .addConverterFactory(GsonConverterFactory.create())
                .build();

还使用了另一个gson实现：

  Gson gson = new GsonBuilder().registerTypeHierarchyAdapter(String.class,
                new JsonDeserializer<String>() {

                    @Override
                    public String deserialize(JsonElement json, Type typeOfT,
                                              JsonDeserializationContext context)
                            throws JsonParseException {
                        return null;
                    }
                }).create();

所以，使用具有完全相同的参数，标题和端点的Postman，响应是一个JSONObject，如图所示，但是使用这个android实现，正文是空的。

修改

我尝试使用pojo类：

public class user implements Serializable {

long id;
String first_name;
String last_name;



public user(){}

public long getId() {
    return id;
}

public void setId(long id) {
    this.id = id;
}

public String getFirst_name() {
    return first_name;
}

public void setFirst_name(String first_name) {
    this.first_name = first_name;
}

public String getLast_name() {
    return last_name;
}

public void setLast_name(String last_name) {
    this.last_name = last_name;
}

@Override
public String toString() {
    return "user{" +
            "id=" + id +
            ", first_name='" + first_name + '\'' +
            ", last_name='" + last_name + '\'' +

            '}';
}
}

但结果是一样的。所有值都为null：

responsefinal body: user{id=0, first_name='null', last_name='null'}

啊你试图从响应中获得JSON但是你正在使用转换器我认为这是不可能的。您需要删除addConverterFactory或创建POJO类，并从POJO获取值。例如：

public class MyClass {

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    @SerializedName("user")
    private User user;

    private class User {

        public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }

        public String getFirstName() {
            return firstName;
        }

        public void setFirstName(String firstName) {
            this.firstName = firstName;
        }

        public String getLastName() {
            return lastName;
        }

        public void setLastName(String lastName) {
            this.lastName = lastName;
        }

        @SerializedName("last_name")
        private String lastName;
        @SerializedName("id")
        private String id;
        @SerializedName("first_name")
        private String firstName;
    }
}

将JSONObject替换为MyClass，作为回应，您将能够getUser()和用户信息。

使用Android Retrofit 2 Httpok3的空响应主体
