改造:使用 JSON 数组发送 POST 请求 [英] Retrofit: Sending POST request with JSON Array

问题描述

我有 JsonElement jsonElement 对象，我从另一个 GET 请求收到它作为响应.jsonElement.toString();看起来像 JSON 数组:

I have JsonElement jsonElement object which I receive as response from my another GET request. jsonElement.toString(); looks like JSON array:

[{"Id":493,"Number":"380936831127","FriendNumber":"380682140976"},{"Id":494,"Number":;380936831127","FriendNumber":"380638254108"}]

我需要使用 Retrofit 通过另一个 POST 请求发送此字符串.如何通过 POST 请求发送 jsonElement 或 String 对象?我的方法的声明应该如何看?例如:

I need to send this string via another POST request using Retrofit. How can I send jsonElement or String object via POST request? How should look declaration of my method? For example:

 @POST("/api/geo/getLoc")
    public void getFriendsLocation(/* something */,  Callback<JsonElement> response);

推荐答案

如果您通过请求正文发送数据，您的实现应该是这样的:

If you are sending data over request body your implementation should be like this:

1. 根据字段定义模型(区分大小写的名称"-> 字符串名称等)

2. 同样设置你的api函数

1. Define model according to fields (CaseSensitive "Name" -> String Name etc )

2. set your api function also like that

@POST("/api/geo/getLoc")
public void getFriendsLocation(@Body YourClass classObject,   Callback<JsonElement> response);

在发布请求时直接使用您创建的类对象

Use directly your created class object on post request

getFriendsLocation(yourClassObjectThatIncludesFields, new Callback .... )

<小时>

如果您通过参数发送数据，您可以使用 Gson 执行此操作.

---

If your sending data over params You can do this with Gson.

1. 假设您有一个包含 id 、 number 和 FriendNumber 等字段的类.定义一个函数:

1. Lets say you have a class that have fields like id , number and FriendNumber.Define a function :

public static Map<String, Object> getMapFromObject(Object o) {
    Gson gson = new Gson();
    Type stringObjectMap = new TypeToken<Map<String, Object>>() {
     }.getType();
    return gson.fromJson(gson.toJson(o), stringObjectMap);
}

同样设置你的api函数

set your api function also like that

@POST("/api/geo/getLoc")
public void getFriendsLocation(@QueryMap Map<String, Object>,     Callback<JsonElement> response);

当您从您的字段发送 post 请求时，请在此处调用此函数，如下所示

When you are sending post request create object from your fields call this function like below here

getFriendsLocation(getMapFromObject(yourClassObjectThatIncludesFields), new Callback .... )

我没有编写包含类定义和回调函数的完整代码，因为它们取决于您的自定义.我假设您需要发送正文，因此请尝试第一种方式.

I didnt write whole code which includes class definition and Callback function because they are up to your customization. I assume that you need to send over body so try the first way.
