Angular $http 配置超时

Question

如 angular 文档中所述，

timeout – {number|Promise} – timeout in milliseconds, or promise that should abort the request when resolved.

现在我正在设置超时来保证，所以我可以通过promise.resolve()手动取消请求。

现在，我也想让它能够配置超时值，而不是让请求超时为 120 秒。

如何配置它而不影响现有的取消请求功能？

你可以这样做

$scope.qPromiseCall = function()
{
       var timeoutPromise = $timeout(function()
       {       
               //aborts the request when timed out
               canceler.resolve(); 
               console.log("Timed out");
        }, 250); 

//we set a timeout for 250ms and store the promise in order to be cancelled later if the data does not arrive within 250ms

     var canceler = $q.defer();
     $http.get("data.js", {timeout: canceler.promise} )
     .success(function(data)
     {
           console.log(data);
           $timeout.cancel(timeoutPromise);
           //cancel the timer when we get a response within 250ms
    });

  }
