Question

我是meteor的新手，我正在关注第一个教程（TODO LIST），但是使用了我自己的例子。所以我能够通过客户端模板将一个表单提交到mongo DB中但不安全。现在，我正在使用此代码在客户端和服务器上定义文件的方法 - cliente.js：

import { Meteor } from 'meteor/meteor';
import {Mongo} from 'meteor/mongo';
import { check } from 'meteor/check';

export const Clientes = new Mongo.Collection('clientes');

Meteor.methods({
  'clientes.insert'(nome, idade,genero,sessao,data,quemPreenche) {
        check(nome, String);
        check(idade, String);
        check(genero, String);
        check(sessao, String);
        check(data, Date);
        check(quemPreenche, String);
        // Make sure the user is logged in before inserting a task
        if (! this.userId) {
          throw new Meteor.Error('not-authorized');
        }

        Clientes.insert({
          nome,
          idade,
          genero,
          sessao,
          data,
          quemPreenche,
          createdAt: new Date(),
          owner: this.userId,
          username: Meteor.users.findOne(this.userId).username,
        });
      },
});

在客户端，我正在调用这样的方法 - novasessao.js：

import { Meteor } from 'meteor/meteor';
import { Template } from 'meteor/templating';
import { Perguntas } from '../api/perguntas.js';
import { Clientes } from '../api/clientes.js';


import './novasessao.html';

Template.novasessao.events({
'keypress form.nova-sessao' : function (event){
    if (event.which === 13) {
            event.preventDefault();
            let dadosclientes = {};
            const target = event.currentTarget;
            const nome = target.nome.value;
            const idade = target.idade.value;
            const genero = target.genero.value;
            const sessao = target.sessao.value;
            const data = target.data.value;
            const quemPreenche = target.quemPreenche.value;
           Meteor.call('clientes.insert',{nome,idade,genero,sessao,data,quemPreenche});
     }
   }
 });

问题是我无法再提交以下错误：

Exception while simulating the effect of invoking 'clientes.insert' errorClass {message: "Match error: Expected string, got object", path: "", sanitizedError: errorClass, errorType: "Match.Error", stack: "Error↵    at exports.check (http://localhost:3000/…983d07ae9423dd57f5b3c9f92b5593d2952f1b86:3717:25)"} Error

有人可以帮忙吗？

谢谢！

当你保存到Mongo时，你需要给它一个JSON对象。

替换部分客户端代码：

target: event.currentTarget;

let dadosclientes = {
    nome: target.nome.value,
    idade: target.idade.value,
    genero: target.genero.value,
    sessao: target.sessao.value,
    data: target.data.value,
    quemPreenche: target.quemPreenche.value
};
Meteor.call('clientes.insert',dadosclientes);

并在服务器中：

  'clientes.insert'(dadosclientes) {
    check(dadosclientes.nome, String);
    check(dadosclientes.idade, String);
    check(dadosclientes.genero, String);
    check(dadosclientes.sessao, String);
    check(dadosclientes.data, Date);
    check(dadosclientes.quemPreenche, String);
    // Make sure the user is logged in before inserting a task
    if (! this.userId) {
      throw new Meteor.Error('not-authorized');
    }

    dadosclientes.createdAt = new Date();
    dadosclientes.owner = this.userId;
    dadosclientes.username = Meteor.users.findOne(this.userId).username;
    Clientes.insert(dadosclientes);
  }

Answer 2

您收到错误是因为您正在将对象类型值传递给方法。您还可以阅读错误＆＃34;匹配错误：预期字符串，获取对象＆＃34;。这是通过支票包发生的。

因此，在发送检查之前，请确保您发送的是正确的类型。

一旦通过所有检查。你的功能仍然会有mongo错误。因为您没有在insert方法中发送有效对象。

Clientes.insert({
    nome,    //This is a string
    idade,   //This is a string
    genero,  //This is a string
    sessao,  //This is a string
    data,    //This is a date
    quemPreenche,  //This is a string
    createdAt: new Date(),  
    owner: this.userId,
    username: Meteor.users.findOne(this.userId).username,
});

所以这不是一个有效的对象。所以你必须创建一个键值对象。喜欢：

Clientes.insert({
    nome:nome,
    idade:idade,
    genero: genero,
    sessao:sessao,
    data:data,
    quemPreenche:quemPreenche,
    createdAt: new Date(),  
    owner: this.userId,
    username: Meteor.users.findOne(this.userId).username,
});

Answer 3

您的初始错误非常简单，您可以使用 6 个别参数的参数列表定义方法：

'clientes.insert'(nome,idade,genero,sessao,data,quemPreenche)

但是您使用以下命令从事件处理程序中调用它：

Meteor.call('clientes.insert',{nome,idade,genero,sessao,data,quemPreenche});

只有一个参数，一个对象。

删除调用中的大括号可以解决最初的问题：

Meteor.call('clientes.insert',nome,idade,genero,sessao,data,quemPreenche);

使用Meteor.call插入多个字段，问题
