android - Retrofit Post json 遇到问题

Question

比如这样的接口
http://www.xxx.com/xxx/xxx

post方式传

 token＝"xxx"
 param＝"{user:{id:xxx,name:xxx},order:{id:xxx}}"

用retrofit 该怎么传？

我现在的方法
表单形式上传

@Field("token") string token
@Field("param") string param

Answer 1

將需要請求的資料定義成一個實體類別

public class CustomBody {

    public String token;
    public User user;
    public Order order;

    public CustomBody(String token, User user, Order order) {
        this.token = token;
        this.user = user;
        this.order = order;
    }

    public static class Order {
        public String id;

        public Order(String id) {
            this.id = id;
        }
    }

    public static class User {
        public String id;
        public String name;

        public User(String id, String name) {
            this.id = id;
            this.name = name;
        }
    }

}

Retrofit 的 Service 這樣子寫就可以了，用 @Body 註解

public interface MyService {

    @POST("/")
    Observable<T> access(@Body CustomBody customBody);
}

使用 HttpLoggingInterceptor 可以在 log 中查看 HTTP 請求的詳細情況。

OkHttpClient.interceptors().add(new HttpLoggingInterceptor());
