如何将GSON库中的JSON字符串转换为JSON对象？
我知道有些线程也有类似的问题，但是我找不到适合的解决方案。
我是移动开发的初学者。我有点困惑如何将JSON string转换为普通JSON。
因此我将JSON称为string，如下所示，此json string是由GSON生成的，将Java对象转换为此{ {1}} JSON：

从
生成JSON字符串string并且那个new Gson().toJson(cartItemsList)
是类cartItemsList的实例
CartProduct和类public class CartProduct {
@SerializedName("customers_id")
@Expose

public void setCustomersBasketProductAttributes(List<CartProductAttributes> customersBasketProductAttributes) {

CartProductAttributes这是ProductDetails类

并且我想将该字符串JSON转换为真实的JSON，例如：

@SerializedName("motorist_id")

@Override

}
因此，我可以读取和复制该{
"type": "donut",
"name": "Cake",
"toppings": [
{ "id": "5002", "type": "Glazed" },
{ "id": "5006", "type": "Chocolate with Sprinkles" },
{ "id": "5004", "type": "Maple" }
]
}
，并使用快速编程语言将其作为JSON字符串从我的iOS设备发送到服务器。因为我需要像这样在请求正文中发布JSON字符串：
我从我们的Android开发人员那里得到了JSON JSON。这个string JSON是从Android中的string库生成的，它像这样从Java Object转换为GSON字符串。不幸的是，Android开发人员也不了解如何将其转换为真实的JSON，而不是JSON JSON。
