我有一个拦截器来调用我的RESTful服务时捕获http错误:
services.config(function($httpProvider) {
$httpProvider.responseInterceptors.push('globalInterceptor');
var elementsList = $();
// this message will appear for a defined amount of time and then vanish again
var showMessage = function(content, cl, time) {
$('<div/>')
.addClass(cl)
.hide()
.fadeIn('fast')
.delay(time)
.fadeOut('fast', function() { $(this).remove(); })
.appendTo(elementsList)
.text(content);
};
});
services.factory('globalInterceptor', function($q){
//When the interceptor runs, it is passed a promise object
return function(promise){
//In an interceptor, we return another promise created by the .then function.
return promise.then(function(successResponse){
//Do your code here if the response was successful
if (typeof(successResponse) !== 'undefined') {
if (successResponse.config.method.toUpperCase() != 'GET') {
showMessage('Success', 'http-success-message', 5000);
return successResponse;
}
}
}, function(errorResponse){
switch (errorResponse.status) {
case 400: // if the status is 400 we return the error
showMessage(errorResponse.data.message, 'http-error-message', 6000);
// if we have found validation error messages we will loop through
// and display them
if(errorResponse.data.errors.length > 0) {
for(var i=0; i<errorResponse.data.errors.length; i++) {
showMessage(errorResponse.data.errors[i],
'http-error-validation-message', 6000);
}
}
break;
case 401: // if the status is 401 we return access denied
showMessage('Wrong email address or password!',
'http-error-message', 6000);
break;
case 403: // if the status is 403 we tell the user that authorization was denied
showMessage('You have insufficient privileges to do what you want to do!',
'http-error-message', 6000);
break;
case 500: // if the status is 500 we return an internal server error message
showMessage('Internal server error: ' + errorResponse.data.message,
'http-error-message', 6000);
break;
default: // for all other errors we display a default error message
showMessage('Error ' + errorResponse.status + ': ' + errorResponse.data.message,
'http-error-message', 6000);
}
return $q.reject(errorResponse);
});
}
});
我的登录页面在加载时停止。在制作接收器之后出现了问题,在此之前一切正常。
它给了我这个错误消息,实际上没有帮助:

我试图调试/ console.log这个“数据”属性但无法找到它...当应用程序加载时,它获得两个文件OK(200和数据attr)和其中两个错误。
任何帮助将非常感谢:-)
我没有看到你的函数有任何问题(errorResponse)。它似乎正确地传递了链中的错误。
但我的功能有问题(successResponse)。只有当两个IF语句在其他情况下通过未定义时,它才会将值传递给链。
我的猜测是你需要在函数末尾添加$ q.reject()(成功响应)。
