在普通函数中调用暂停函数 [英] call a suspend function inside a normal function

问题描述

我想在普通函数中调用阻止暂停函数，但不阻止线程完成暂停函数，然后返回 Response

I want to call blocking a suspend function in a normal function, but does not block Thread to finishing suspend function and then return Response

override fun intercept(chain: Interceptor.Chain): Response {

    // getSession is a suspend function
    val session = sessionProvider.getSession()

    return chain.proceed(
        chain
            .request()
            .newBuilder()
            .addHeader("Authorization", "${session.token}")
            .build()
    )
}

推荐答案

这似乎是在实现OkHttp拦截器，所以我希望 intercept（）

This looks like you are implementing an OkHttp interceptor, so I am hoping that intercept() is being called on a background thread.

如果是这样，使用 runBlocking（） ：

If so, use runBlocking():

override fun intercept(chain: Interceptor.Chain): Response {

    // getSession is a suspend function
    val session = runBlocking { sessionProvider.getSession() }

    return chain.proceed(
        chain
            .request()
            .newBuilder()
            .addHeader("Authorization", "${session.token}")
            .build()
    )
}

runBlocking（）将执行 suspend 函数，阻塞当前线程，直到该工作完成。

runBlocking() will execute the suspend function, blocking the current thread until that work is complete.
