How to set a global http timeout in AngularJs

小开

最佳答案

UPDATED: $http will not respect default setting for timeout set it in httpProvider (see the comments). Possible workaround: https://gist.github.com/adnan-i/5014277

Original answer:

angular.module('MyApp', [])
.config(['$httpProvider', function($httpProvider) {
$httpProvider.defaults.timeout = 5000;
}]);

This is possible with bleeding-edge angular.js (tested with git master 4ae46814ff).

You can use request http interceptor. Like this.

 angular.module('yourapp')
.factory('timeoutHttpIntercept', function ($rootScope, $q) {
return {
'request': function(config) {
config.timeout = 10000;
return config;
}
};
});

And then in .config inject $httpProvider and do this:

$httpProvider.interceptors.push('timeoutHttpIntercept');

Thanks for the post and update!!

In researching this issue specifically for $resource, I thought I'd elaborate on what I've found:

This issue was logged in the tracker and in angular 1.1.5, there is support for passing the timeout property through to the $http request:

https://github.com/angular/angular.js/issues/2190 http://code.angularjs.org/1.1.5/docs/api/ngResource.$resource

For those of us on earlier versions, specifically I am using angular 1.0.6, it is possible to edit the source file for angular-resource.js on line 396 you will find the call to $http where you can add the timeout property yourself for all resource requests.
Since it wasn't mentioned and I had to test Stewie's solution, when a timeout does occur, the way to tell between an error and an abort/timeout is checking the 'status' argument. It will return 0 for timeouts instead of say 404:
```
$http.get("/home", { timeout: 100 })
.error(function(data, status, headers, config){
console.log(status)
}
```

Since there are only a few cases where I need to use a timeout as opposed to setting it globally, I am wrapping the requests in a $timeout function, like so:

//errorHandler gets called wether it's a timeout or resource call fails


var t = $timeout(errorHandler, 5000);
myResource.$get( successHandler, errorHandler )
function successHandler(data){
$timeout.cancel(t);
//do something with data...
}


function errorHandler(data){
//custom error handle code
}

I've the same requirement and I m using AngularJS 1.0.7. I've come up with the below code as none of the above solutions seems feasible for me (feasible in the sense I want timeout to be global at one place). Basically, I m masking the original $http methods and adding timeout for each $http request and overriding other shortcut methods, like get, post, ... so that they'll use the new masked $http.

JSFiddle for below code:

/**
* @name ngx$httpTimeoutModule
* @description Decorates AngularJS $http service to set timeout for each
* Ajax request.
*
* Implementation notes: replace this with correct approach, once migrated to Angular 1.1.5+
*
* @author Manikanta G
*/
;(function () {
'use strict';


var ngx$httpTimeoutModule = angular.module('ngx$httpTimeoutModule', []);


ngx$httpTimeoutModule.provider('ngx$httpTimeout', function () {
var self = this;
this.config = {
timeout: 1000 // default - 1 sec, in millis
};


this.$get = function () {
return {
config: self.config
};
};
});


/**
* AngularJS $http service decorator to add timeout
*/
ngx$httpTimeoutModule.config(['$provide',  function($provide) {


// configure $http provider to convert 'PUT', 'DELETE' methods to 'POST' requests
$provide.decorator('$http', ['$delegate', 'ngx$httpTimeout', function($http, ngx$httpTimeout) {
// create function which overrides $http function


var _$http = $http;


$http = function (config) {
config.timeout = ngx$httpTimeout.config.timeout;
return _$http(config);
};
$http.pendingRequests = _$http.pendingRequests;
$http.defaults = _$http.defaults;


// code copied from angular.js $HttpProvider function
createShortMethods('get', 'delete', 'head', 'jsonp');
createShortMethodsWithData('post', 'put');


function createShortMethods(names) {
angular.forEach(arguments, function(name) {
$http[name] = function(url, config) {
return $http(angular.extend(config || {}, {
method : name,
url : url
}));
};
});
}


function createShortMethodsWithData(name) {
angular.forEach(arguments, function(name) {
$http[name] = function(url, data, config) {
return $http(angular.extend(config || {}, {
method : name,
url : url,
data : data
}));
};
});
}


return $http;
}]);


}]);


})();

Add dependency on the above module, and configure the timeout by configuring ngx$httpTimeoutProvider, like below:

angular.module('App', ['ngx$httpTimeoutModule']).config([ 'ngx$httpTimeoutProvider', function(ngx$httpTimeoutProvider) {
// config timeout for $http requests
ngx$httpTimeoutProvider.config.timeout = 300000; // 5min (5 min * 60 sec * 1000 millis)


} ]);
