RestangularProvider.setErrorInterceptor(
function ( response ) {
if ( response.status == 401 ) {
dialogs.error("Unauthorized - Error 401","You must be authenticated in order to access this content.")
.result.then( function () {
$location.path("/login");
});
}
else {
// Some other unknown Error.
console.log( response );
dialogs.error(response.statusText + " - Error " + response.status,"An unknown error has occurred.<br>Details: " + response.data);
}
// Stop the promise chain.
return false;
}
);
function saveApple( apple ) {
Restangular.all("apple/save").post( apple ).then(
function ( response ) {
console.log("Saved");
},function ( response ) {
// This is not being called.
console.log("Error with status code",response.status);
}
);
}
据我所知,我的“第二个”错误处理程序没有被调用,因为我在ErrorInterceptor上返回false.
但我怎么能解决这个问题呢？我的应用程序中有很多“REST操作”,只有少数几个,我想在出现问题时进行自定义行为.
到目前为止,我想到的唯一解决方法是使ErrorInterceptor返回true,对于其他所有REST操作,我复制粘贴相同的错误处理程序(更常见的一个).但这将是我要做的最后一件事.
现在,像这样流淌：
> ErrorInterceptor>结束.
如果可能的话,我希望它是这样的:(仅适用于特定方法 – 不是全部).
> ErrorInterceptor> Especific_ErrorHandler(如果存在)>结束.
它也可以是这样的：
> Especific_ErrorHandler(如果存在)> ErrorInterceptor>结束.
无论哪种方式都适合我.

你为什么使用拦截器？
– 因为你想要全面的对话框来显示错误信息.
停止承诺链,这是不好的做法？
我不知道.很多人使用错误回调;并且一个用于错误回调的用例是进行一些清理.如果你杀了承诺链,你如何确保清理完成？停止promise链意味着你的错误回调,你的catch块和你的finally块都不会被调用.
在文档中,清理完成后,您可以看到deferred.reject被传递.

也许你误解了文档中的例子.
可能的解决方案#1
// DON'T stop the promise chain.
return true;
可能的解决方案#2
RestangularProvider.setErrorInterceptor(
function ( response ) {
if ( response.status == 401 ) {
dialogs.error("Unauthorized - Error 401","You must be authenticated in order to access this content.")
.result.then( function () {
$location.path("/login");
});
// Stop the promise chain.
// all unauthorized access are handled the same.
return false;
}
// Some other unknown Error.
console.log( response );
dialogs.error(response.statusText + " - Error " + response.status,"An unknown error has occurred.<br>Details: " + response.data);
}
// DON'T stop promise chain since error is not handled
return true;
}
);
可能的解决方案#3
停止承诺链时调用拒绝.
RestangularProvider.setErrorInterceptor(
function ( response,deferred,responseHandler ) {
if ( response.status == 401 ) {
dialogs.error("Unauthorized - Error 401","You must be authenticated in order to access this content.")
.result.then( function () {
// continue promise chain in this callback.
deferred.reject("unauthorized");
$location.path("/login");
});
// Stop the promise chain here
// all unauthorized access are handled the same.
return false;
}
// Some other unknown Error.
console.log( response );
dialogs.error(response.statusText + " - Error " + response.status,"An unknown error has occurred.<br>Details: " + response.data);
}
// DON'T stop promise chain since error is not handled
return true;
}
);
