如何访问这个Api?

Question

所以我正在玩API的。我正在尝试使用这个API https://rickandmortyapi.com/documentation/#character-schema

我可以调用list 来访问这个

https://rickandmortyapi.com/api/character/1,183
[
{
"id": 1,
"name": "Rick Sanchez",
"status": "Alive",
"species": "Human",
"type": "",
"gender": "Male",
"origin": {
"name": "Earth (C-137)",
"url": "https://rickandmortyapi.com/api/location/1"
},
"location": {
"name": "Earth (Replacement Dimension)",
"url": "https://rickandmortyapi.com/api/location/20"
},
"image": "https://rickandmortyapi.com/api/character/avatar/1.jpeg",
"episode": [
"https://rickandmortyapi.com/api/episode/1",
"https://rickandmortyapi.com/api/episode/2",
// ...
],
"url": "https://rickandmortyapi.com/api/character/1",
"created": "2017-11-04T18:48:46.250Z"
},
{
"id": 183,
"name": "Johnny Depp",
"status": "Alive",
"species": "Human",
"type": "",
"gender": "Male",
"origin": {
"name": "Earth (C-500A)",
"url": "https://rickandmortyapi.com/api/location/23"
},
"location": {
"name": "Earth (C-500A)",
"url": "https://rickandmortyapi.com/api/location/23"
},
"image": "https://rickandmortyapi.com/api/character/avatar/183.jpeg",
"episode": [
"https://rickandmortyapi.com/api/episode/8"
],
"url": "https://rickandmortyapi.com/api/character/183",
"created": "2017-12-29T18:51:29.693Z"
}
]

get all characters调用

出现问题

https://rickandmortyapi.com/api/character
{
"info": {
"count": 671,
"pages": 34,
"next": "https://rickandmortyapi.com/api/character/?page=2",
"prev": null
},
"results": [
{
"id": 1,
"name": "Rick Sanchez",
"status": "Alive",
"species": "Human",
"type": "",
"gender": "Male",
"origin": {
"name": "Earth",
"url": "https://rickandmortyapi.com/api/location/1"
},
"location": {
"name": "Earth",
"url": "https://rickandmortyapi.com/api/location/20"
},
"image": "https://rickandmortyapi.com/api/character/avatar/1.jpeg",
"episode": [
"https://rickandmortyapi.com/api/episode/1",
"https://rickandmortyapi.com/api/episode/2",
// ...
],
"url": "https://rickandmortyapi.com/api/character/1",
"created": "2017-11-04T18:48:46.250Z"
},
// ...
]
}

我这样称呼它

@GET("character")
suspend fun getAll() : Response<Characters>
}

我得到的只是这个

响应{protocol=h2, code=200, message=， url=https://rickandmortyapi.com/api/character}

如何访问"结果"?列表从得到所有字符端点?我还在学习。我已经管理了基本的API，但这一个是在我的头上。

下面是我使用的插件生成的类。

data class Characters(
val created: String,
val episode: List<Any>,
val gender: String,
val id: Int,
val image: String,
val location: Location,
val name: String,
val origin: Origin,
val species: String,
val status: String,
val type: String,
val url: String
)
data class Location(
val name: String,
val url: String
)
data class Origin(
val name: String,
val url: String
)

Answer 1

您将需要另一个POJO类。假设你命名它为AllResponse

data class AllResponse(
val info: Info,
val characters: List<Characters>
)

在你的服务类

@GET("character")
suspend fun getAll() : Response<AllResponse>

访问字符列表

val call = myService.getAll()
call.enqueue(object : Callback<AllResponse> {
override fun onResponse(call: Call<AllResponse>, response: Response<AllResponse>) {
if (response.isSuccessful) {
val allResponse = response.body()
val characters = allResponse.characters
}
}
override fun onFailure(call: Call<Characters>, t: Throwable) {
}
})

Answer 2

我认为Divij Gupta在POJO类方面是正确的。但是既然你用的是suspend。我认为你需要一个协程来从api获取结果。

val call. myService.getAll()
if(call.isSuccessful) {  <-- coroutines's way to get result in sequential.
call.body()?.let {
val characters = it.characters
}
} else {
// handle error here
}

PS:你可以考虑把这些放在存储库中，并得到你的viewModel的值。

Answer 3

@FormUrlEncoded
@POST("xyz")
Call<SamplePojo> getData(
@Field("xyx") String xyz,
);

或

@GET("xyz")
Call<SamplePojo> getData();
