增加Angular 2+和ASP.NET Core WebAPI应用程序中的超时 [英] Increase timeout in Angular 2+ and ASP.NET Core WebAPI application

问题描述

在我的Angular 2+/ASP.NET Core MVC WebAPI应用程序中，我从客户端UI到服务器进行了长时间运行的API调用. 30秒后，请求超时.我想为此客户端或服务器端的特定API调用定义超时.

In my Angular 2+ / ASP.NET Core MVC WebAPI application I have a long running API-call from the client UI to the server. The request times out after 30 seconds. I would like to define the timeout for this specific API call either client- or server-side.

我只找到了全局配置服务器超时的方法，这不是我想要的，因为30秒的超时对于其他呼叫来说是可以的.我还发现了通过传递RxJS的timeout运算符来减少超时客户端的解决方案.但是，据我了解，这不适合 增加超时时间吗?

I have only found ways to configure the server timeout globally, which is not what I want, as the 30 second timeout is fine for other calls. I've also found solutions to decrease the timeout client side by piping RxJS's timeout operator. However, as I understand, this is not suitable for increasing the timeout?

如何设置此特定请求的超时时间? 30秒默认值是从哪里来的?

How can I set the timeout on this specific request? Where does the 30 second default come from?

(该代码实际上并不重要，因为它是标准的API控制器和标准的Angular HTTP调用):

(The code doesn't actually matter, as it is a standard API controller and a standard Angular HTTP call):

this.http.get('api/xyz').subscribe(d => { ... });

推荐答案

要解决超时问题，您可以使用如下所示的RxJ中的timeout

To solve the timeout issue you can use the timeout from RxJs like below

向timeout运算符

这里我要传递60秒的超时时间，因此60秒后如果服务器没有响应，则会抛出超时错误.

Here I am passing 60 seconds as timeout, so after 60 seconds if there is no response from the server then it will throw timeout error.

import ‘rxjs/add/operator/timeout’; 

...

this.http.get('api/xyz').timeout(60000).subscribe(d => { ... });
