Mongoose: RangeError：在 url 中添加 jsonwebtoken 后将数据更新到数据库时超出了最大调用堆栈大小

创建于 2018-03-07 · 3评论 · 资料来源: Automattic/mongoose

在我的应用程序（一个信使应用程序，当我输入新消息时，在消息（字符串）输入中，然后单击提交，节点服务器关闭，出现以下错误
尽管我在输入表单中提交的新消息已保存在数据库中。当我重新启动节点服务器时，它就会出现。

我的 ../models/messages.js 中的内容

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var User = require('./user');

var schema = new Schema({
    content: {type: String, required: true},
    user: {type: Schema.Types.ObjectId, ref: 'User'}
});

schema.post('remove', function (message) {
    User.findById(message.user, function (err, user) {
        user.messages.pull(message);
        user.save();
    });
});

module.exports = mongoose.model('Message', schema);

在我将 jsonwebtoken 的代码插入 ./message/message.service.ts 文件以将令牌添加到我的post url 后，此问题开始发生

addMessage(message: Message) {
        const body = JSON.stringify(message);
        const headers = new Headers({'Content-Type': 'application/json'});
        const token = localStorage.getItem('token')
            ? '?token=' + localStorage.getItem('token')
            : '';
        return this.http.post('http://localhost:3000/message' + token, body, {headers: headers})
            .map((response: Response) => {
                const result = response.json();
                const message = new Message(
                    result.obj.content,
                    result.obj.user.firstName,
                    result.obj._id,
                    result.obj.user._id);
                this.messages.push(message);
                return message;
            })
            .catch((error: Response) => Observable.throw(error.json()));
    }

嗨@rohan-paul，

感谢您使这很容易解决问题。我克隆了您的 repo，需要更改 2 行才能使其正常工作：

进行这些更改后* 我能够添加消息而不会崩溃。
我对 ts 没有任何有意义的经验，我在 npm install 上遇到了一个关于本地编译一些 ts 包的错误，所以我只是编辑了 js，没有深入研究 ts。 希望这可以帮助。
