Question

我的synatx中有一个错误，我正在创建忘记密码功能。

我得到的错误就是这个

[TypeError: self._forgotPasswordRouteHelper.sendPasswordResetEmail is not a function]

我的路线如下所示

getRoute(): hapi.IRouteConfiguration {
        const self = this;
        return {
            method: 'POST',
            path: this._config.apiPrefix + 'forgotpassword',
            handler: function(request: hapi.Request, reply: hapi.IReply) {
                let parsedRequest: IForgotPasswordDataRequest = null;
                let uuid: string;
                const result = new Promise<string>(function(resolve, reject) {
                    self._validator.validate(request.payload, ForgotPasswordDataRequestValidator)
                        .then(function(validationResult) {
                            if (validationResult.error) {
                                resolve(responseHelper.getErrorResponse(ResponseErrorCode.invalidRequest));
                                throw null;
                            }
                            parsedRequest = <IForgotPasswordDataRequest> request.payload;
                            return self._forgotPasswordQueries.createEmailResetToken(parsedRequest.email);
                        }
                        , function(error) {
                            console.error(error);
                            resolve(responseHelper.getErrorResponse(ResponseErrorCode.invalidRequest));
                            throw null;
                        })
                        .then(function(newUuid: string) {
                            uuid = newUuid;
                            return self._peopleQueries.getPersonByEmail(parsedRequest.email);
                        })
                        .then(function(person: IPersonModel) {
                            resolve(responseHelper.getSuccessResponse(null, null));
                            self._forgotPasswordRouteHelper.sendPasswordResetEmail(uuid, parsedRequest.email, person.name_to_call_user);
                        })
                        .catch(function(error: any) {
                            console.error(error);
                            resolve(responseHelper.getErrorResponse(ResponseErrorCode.unknownError));
                        });
                });
                reply(result);
            }
        };

在我的forgotPasswordHelper.ts文件中，我有一个像这样的函数

sendPasswordResetEmail(person: any): Promise<void> {
    const token = person.forgot_password_token.dataValues.forgot_password_tokens_id;
    const data: IForgotPasswordEmailEmailData = {
        'resetUrl': this._config.websiteUrl + 'reset_password/confirm/' + token,
        'emailTo': person.contact_detail.value,
        'name': person.person.name_to_call_user
    }
    return this._emailHelper.sendPasswordResetEmail(data);
}

我不确定我哪里出错了？这可能是语法错误吗？当我在邮递员中发布该网址时，我会获得运行此功能并发送电子邮件所需的所有数据，但是我收到了错误

self._forgotPasswordRouteHelper.sendPasswordResetEmail(uuid, parsedRequest.email, person.name_to_call_user);

试试这个：

getRoute(): hapi.IRouteConfiguration {
        const self = this;
        return {
            method: 'POST',
            path: this._config.apiPrefix + 'forgotpassword',
            handler: function(request: hapi.Request, reply: hapi.IReply) {
                const me = self;
                let parsedRequest: IForgotPasswordDataRequest = null;
                let uuid: string;
                const result = new Promise<string>(function(resolve, reject) {
                    me._validator.validate(request.payload, ForgotPasswordDataRequestValidator)
                        .then(function(validationResult) {
                            if (validationResult.error) {
                                resolve(responseHelper.getErrorResponse(ResponseErrorCode.invalidRequest));
                                throw null;
                            }
                            parsedRequest = <IForgotPasswordDataRequest> request.payload;
                            return self._forgotPasswordQueries.createEmailResetToken(parsedRequest.email);
                        }
                        , function(error) {
                            console.error(error);
                            resolve(responseHelper.getErrorResponse(ResponseErrorCode.invalidRequest));
                            throw null;
                        })
                        .then(function(newUuid: string) {
                            uuid = newUuid;
                            return me._peopleQueries.getPersonByEmail(parsedRequest.email);
                        })
                        .then(function(person: IPersonModel) {
                            resolve(responseHelper.getSuccessResponse(null, null));
                            me._forgotPasswordRouteHelper.sendPasswordResetEmail(uuid, parsedRequest.email, person.name_to_call_user);
                        })
                        .catch(function(error: any) {
                            console.error(error);
                            resolve(responseHelper.getErrorResponse(ResponseErrorCode.unknownError));
                        });
                });
                reply(result);
            }
        };

你有嵌套的闭包（这就是为什么我在处理程序中声明了一个新的me变量，处理程序中的匿名函数与处理程序的作用域不同）。尽量避免这种结构。
