【问题描述】：

https://api.mojilala.com/v1/stickers/trending?api_key=dc6zaTOxFJmzC

data class RootApi(val data : List<AllData>)
data class AllData(val images : ImageSticker)
data class ImageSticker(val fixed_height : ActualImage)
data class ActualImage(val url : String)

根据给定的 api，这是否是正确的 POJO 类

【问题讨论】：

不要公开密钥，否则可能会被滥用。
它是公共 API :)
API 是公开的，但您确定密钥吗？
github.com/mojilala/sticker-api 是的，它是公开的

标签： android json database retrofit rest

【解决方案1】：

首先，在问题中隐藏您的 API 密钥。即将生成 JSON 的数据类。我建议您使用以下插件

https://plugins.jetbrains.com/plugin/9960-json-to-kotlin-class-jsontokotlinclass-

不，这不是正确的数据类。事实上，它非常大。我什至无法将其全部粘贴到答案中。使用插件。粘贴 JSON 响应并自己生成。

【讨论】：

它是一个公共 API，也是免费的 :)

按照@che10 的回答，您应该得到以下结果：

data class Data(
    // Assuming you are using Moshi https://github.com/square/moshi
    // Use @SerializedName("data") if you're using Gson
    @Json(name="data")
    val stickers: List<Sticker>,
    val meta: Meta,
    val pagination: Pagination
)

data class Sticker(
    val designer: String,
    val id: String,
    val images: Images,
    val is_animated: Boolean,
    val rating: String,
    val tags: List<String>,
    val url: String
)

data class Pagination(
    val offset: String,
    val total: Int,
    val total_count: Int
)

data class Meta(
    val msg: String,
    val status: Int
)

// Different fields but of two types so we can reuse the classes
// Difference between AnimatedImage and StillImage is the two webp fields
data class Images(
    // Animated images
    val fixed_height: AnimatedImage,
    val fixed_height_downsampled: AnimatedImage,
    val fixed_height_medium: AnimatedImage,
    val fixed_height_medium_downsampled: AnimatedImage,
    val fixed_height_small: AnimatedImage,
    val fixed_width: AnimatedImage,
    val fixed_width_downsampled: AnimatedImage,
    val fixed_width_medium: AnimatedImage,
    val fixed_width_medium_downsampled: AnimatedImage,
    val fixed_width_small: AnimatedImage,
    // Still images
    val fixed_height_still: StillImage,
    val fixed_height_medium_still: StillImage,
    val fixed_height_small_still: StillImage,
    val fixed_width_still: StillImage,
    val fixed_width_medium_still: StillImage,
    val fixed_width_small_still: StillImage,
)

data class StillImage(
    val url: String,
    val size: Int,
    val height: Int,
    val width: Int,
)

data class AnimatedImage(
    val url: String,
    val size: Int,
    val height: Int,
    val width: Int,
    val webp: String,
    val webp_size: Int
)
