Angular6 捕获超时错误 [英] Angular6 catch timeout error

问题描述

使用此代码，我可以捕获所有异常，但服务器不可用时除外.您知道应该如何处理吗?

with this code I can catch all the exceptions, except the when the server is anavailable. Do you have any idea about how should be handle ?

return this.http.post<User>(this._appSetting.ebit.base_url "rested/login/login", JSON.stringify(params), httpOptions)
                  .pipe(catchError(this.handleError));

推荐答案

您可以使用 timeout() 运算符来捕获超时.它以毫秒为单位测量，所以 10000 将是 10 秒.

You can use the timeout() operator to catch a timeout. It's measured in milliseconds so 10000 would be 10 seconds.

return this.http.post<User>(this._appSetting.ebit.base_url "rested/login/login", JSON.stringify(params), httpOptions)
              .pipe(timeout(10000), catchError(this.handleError));
