deferred.await()，提示suspension functions can be called only within coroutine body,不能通过编译，请问什么原因

挂起函数只能在协程范围内调用

那这应该怎么写？

/**

执行网络请求（结合kotlin 协程使用）
@param deferred 请求的接口
@param isValidateCode 是否验证code，如：登录是否过期
@param context 为null时，登录过期不跳登录页 */ suspend fun request(deferred: Deferred<Response>, isValidateCode: Boolean = false, context: Context? = null): T? = withContext(Dispatchers.Default) { try { val response = deferred.await()===========》此处报错 if (response.isSuccessful) {// 成功 val body = response.body() if (isValidateCode && body != null) { validateCode(context, body.code) } body ?: throw NullBodyException() } else {// 处理Http异常 ExceptionUtil.catchHttpException(response.code()) null } } catch (e: Exception) { // 这里统一处理错误 ExceptionUtil.catchException(e) null } }

你的Presenter文件,有没有从Activity 把协程域传递给Presenter？

参考下： class AddressListPresenter(scope: CoroutineScope) : BasePresenterKt(), CoroutineScope by scope, AddressListContract.Presenter {

override fun deleteAddress(id: String, position: Int) = launch {
    val map = HashMap<String, Any>()
    map["id"] = id
    RetrofitManagerKt.request(RetrofitManagerKt.apiService.requestAsync(map), true, mContext)?.also {
        if (it.code == 0) {
            mView?.deleteAddressSuccess(position)
        } else {
            ToastUtils.showShort(it.message)
        }
    }
}
