我是Retrofit的新手并尝试使用Retrofit发出POST请求.我的POST请求有一个复杂的JSON正文,如下所示：

负载：

{
    "user": {
        "personal_info": {
            "first_name": "Walter",
            "last_name": "White",
            "date_of_birth": "1972-01-03 00:00:00 PST"
        },
        "address_info": {
            "address_1": "308 NEGRA ARROYO LANE",
            "address_2": "#",
            "city": "ALBUQUERQUE",
            "state": "NM",
            "zip_code": "87104"
        },
        "contact_info": {
            "email": "wwhite@test.com",
            "telephone": "88888888888",
            "telephone_type_id": 1
        },
        "employment_info": {
            "employer_name": "SELF",
            "employment_status_id": 7,
            "annual_income": 9000000000000000,
            "monthly_income": 750000000000,
            "employment_start_year": 0,
            "employment_start_month": 0
        }
      }
    }

我将接口定义为

    @POST("/users")
    void registerUser(@Body User User, Callback<User> cb);

我不确定我的User类应该是什么样的,我希望有效负载与上面提到的相同,到目前为止我的User类为

public class User {


    @SerializedName("personal_info")
    private PersonalInfo personalInfo;
    @SerializedName("address_info")
    private AddressInfo addressInfo;
    @SerializedName("contact_info")
    private ContactInfo contactInfo;
    @SerializedName("employment_info")
    private EmploymentInfo employmentInfo;

}

我不确定Personalinfo,ContactInfo等应该是JSON请求中提到的所有字段的单独类,还是我应该将它们作为User类中的内部类以及如何使用User类进行Retrofit调用.服务器响应与上面提到的JSON请求完全类似,有1个附加字段,即用户ID.我准备好了POJO课程以获得响应.

我对如何发出POST请求很困惑.在此先感谢您的帮助.

解决方法:

序列化时的User对象将具有此JSON表示：

{
    "personal_info": {
        "first_name": "Walter",
        "last_name": "White",
        "date_of_birth": "1972-01-03 00:00:00 PST"
    },
    "address_info": {
        "address_1": "308 NEGRA ARROYO LANE",
        "address_2": "#",
        "city": "ALBUQUERQUE",
        "state": "NM",
        "zip_code": "87104"
    },
    "contact_info": {
        "email": "wwhite@test.com",
        "telephone": "88888888888",
        "telephone_type_id": 1
    },
    "employment_info": {
        "employer_name": "SELF",
        "employment_status_id": 7,
        "annual_income": 9000000000000000,
        "monthly_income": 750000000000,
        "employment_start_year": 0,
        "employment_start_month": 0
    }
}

为了按照问题中的说明构建有效负载,您需要另一个类：

public class UserRequest {

    @SerializedName("user")
    private User user;
}

在使用Retrofit执行请求时使用它：

@POST("/users")
void registerUser(@Body UserRequest User, Callback<User> cb);
