angularjs - AngularJS中的全局错误处理

Question

我使用AngularJS和typescript，我还调用Rest服务以从后端检索数据。我的问题是对所有 Controller 全局处理调用错误的最佳方法是什么。

Answer 1

全局处理错误的最好方法是覆盖

'$exceptionHandler'

这是文件链接
“ https://docs.angularjs.org/api/ng/service/ $ exceptionHandler”

(function () {
    'use strict';

    var app = angular.module('app');

    // Configure by setting an optional string value for appErrorPrefix.
    // Accessible via config.appErrorPrefix (via config value).

    app.config(['$provide', function ($provide: ng.auto.IProvideService) {
        $provide.decorator('$exceptionHandler',
            ['$delegate', 'config', 'logger', extendExceptionHandler]);
    }]);

    // Extend the $exceptionHandler service to also display a toast.
    function extendExceptionHandler($delegate: ng.IExceptionHandlerService, config: config, logger: logger) {
        var appErrorPrefix = config.appErrorPrefix;
        var logError = logger.getLogFn('app', 'error');
        return function (exception: Error, cause: string) {
            $delegate(exception, cause);
            if (appErrorPrefix && exception.message.indexOf(appErrorPrefix) === 0) { return; }

            var errorData = { exception: exception, cause: cause };
            var msg = appErrorPrefix + exception.message;
            logError(msg, errorData, true);
        };
    }
})();
