javascript - Angular 拦截器 - 从 500 错误中获取消息

Question

我正在使用 Angular 拦截器，我想从 500 错误(内部服务器错误)中获取消息。

问题是，我在拦截器内的 responseError 中的 rejection.data 中获取了整个 HTML(下面的屏幕截图)。

我读到我必须配置 web.config 但我仍然得到整个 HTML。我只是想收到消息。

这有可能吗？

Angular 拦截器:

app.config(['$httpProvider', function ($httpProvider) {

    $httpProvider.interceptors.push(function ($q, $rootScope) {

        return {
            request: function (config) {

                //the same config / modified config / a new config needs to be returned.
                return config;
            },
            requestError: function (rejection) {

                //Initializing error list
                if ($rootScope.errorList == undefined) {
                    $rootScope.errorList = [];
                }

                $rootScope.errorList.push(rejection.data);

                //It has to return the rejection, simple reject call doesn't work
                return $q.reject(rejection);
            },
            response: function (response) {

                //the same response/modified/or a new one need to be returned.
                return response;
            },
            responseError: function (rejection) {

                //Initializing the error list
                if ($rootScope.errorList == undefined) {
                    $rootScope.errorList = [];
                }

                //Adding to error list
                $rootScope.errorList.push(rejection.data);

                //It has to return the rejection, simple reject call doesn't work
                return $q.reject(rejection);
            }
        };
    });
}]);

Web.Config

<system.webServer>
    <httpErrors existingResponse="PassThrough" errorMode="Detailed"></httpErrors>
</system.webServer>

编辑:我想从异常快照中获取消息

I want to get the message from 500 errors (internal server error).

使用response.statusText获取消息:

responseError: function (errorResponse) {

    //Initializing the error list
    if ($rootScope.errorList == undefined) {
        $rootScope.errorList = [];
    }

    //Adding to error list
    $rootScope.errorList.push(errorResponse.statusText);

    //It has to return the rejection, simple reject call doesn't work
    return $q.reject(errorResponse);
}

来自文档:

The response object has these properties:

• data – {string|Object} – The response body transformed with the transform functions.
• status – {number} – HTTP status code of the response.
• headers – {function([headerName])} – Header getter function.
• config – {Object} – The configuration object that was used to generate the request.
• statusText – {string} – HTTP status text of the response.
