AngularJS : How to prevent a request

Question

是否可以使用 angularjs 拦截器来阻止请求？

$provide.factory('myHttpInterceptor', function($q, someService) {
  return {
    'request': function(config) {
      // here I'd like to cancel a request depending of some conditions
    }
  }
});

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

在 1.1.5 及更高版本中，您可以使用配置对象的“timeout”属性。

来自documentation :

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

简单的例子:

$provide.factory('myHttpInterceptor', function($q, someService) {
  return {
    'request': function(config) {

        var canceler = $q.defer();

        config.timeout = canceler.promise;

        if (true) {

            // Canceling request
            canceler.resolve();
        }

        return config;
    }
  }
});

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