如何使用 Retrofit 进行同步调用

Question

我正在尝试使用 Retrofit call.enqueue ( DrawCircles() ) 获取数据，当我调试时，值在那里，但我认为它不会等待，我的函数继续执行其余行代码。所以问题是我运行它，结果列表（myListCoord）总是空的，如何进行同步调用。

这是我的代码：

 doAsync {
        var a = DrawCircles()
        myListCoord = a.runCircles()
    }
fun runCircles(): List<Coordinates>? {
    val request = ServiceBuilder.buildService(TmdbEndpoints::class.java)
    val call = request.getCorrdinates()

    call.enqueue(object : Callback<MyList> {
        override fun onResponse(call: Call<MyList>, response: Response<MyList>) {
            if (response.isSuccessful){
                Toast.makeText(this@DrawCircles, "Succès", Toast.LENGTH_LONG).show()

                myListCoord = response.body()!!.locations
            }
        }
        override fun onFailure(call: Call<MyList>, t: Throwable) {

            Toast.makeText(this@DrawCircles, "${t.message}", Toast.LENGTH_SHORT).show()
        }

    })
    return myListCoord
}

Answer 1

您是否尝试过使用 call.execute() 而不是 call.enqueue()？

来自docs：

void enqueue(Callback<T> callback) Asynchronously send the request and notify callback of its response or if an error occurred talking to the server, creating the request, or processing the response.

Response<T> execute() throws IOException Synchronously send the request and return its response.
