如何在 android studio 中通过 Retrofit、Coroutine with Kotlin 解析 JSON 数据

Question

我正在为 JSON 解析编写代码，但未检索到 JSON 数据。会是什么问题？

下面是数据对象class

data class UsersItem(
    val avatar_url: String,
    val events_url: String,
    val followers_url: String,
    val following_url: String,
    val gists_url: String,
    val gravatar_id: String,
    val html_url: String,
    val id: Int,
    val login: String,
    val node_id: String,
    val organizations_url: String,
    val received_events_url: String,
    val repos_url: String,
    val site_admin: Boolean,
    val starred_url: String,
    val subscriptions_url: String,
    val type: String,
    val url: String
)

下面是定义的List

class Users : ArrayList<UsersItem>()

下面是 ApiUtilities

object ApiUtilities {
    private val BaseURl = "https://api.github.com/"

    fun getInstance(): Retrofit {
        return Retrofit.Builder().baseUrl(BaseURl)
            .addConverterFactory(GsonConverterFactory.create()).build()
    }
}

下面是ApiInterface

interface ApiInterface {
@GET("/Users")
suspend fun getUsers(): Response<Users>
}

下面是MainActivity，我刚刚测试了获取带有登录 ID 的 JSON 响应，但我没有得到结果。请更正代码或提出任何建议

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val helloTxt = findViewById<TextView>(R.id.txt) as TextView
        val userApi = ApiUtilities.getInstance().create(ApiInterface::class.java)

        GlobalScope.launch {
            val result = userApi.getUsers()
            if (result.isSuccessful && result.body() != null) {
                result.body()?.forEach {
                    Toast.makeText(this@MainActivity, "${it.id}", Toast.LENGTH_LONG).show()
                    Log.d("Manju", "${it.login}")
                    helloTxt.setText("${it.login}")
                }

            }
        }

    }
}

我认为你应该使用带有小写“u”的“/users”：

interface ApiInterface {
@GET("/users")
suspend fun getUsers(): Response<Users>
}

而不是：

interface ApiInterface {
@GET("/Users")
suspend fun getUsers(): Response<Users>
}
