将不同types的值从Node.js插入到MongoDB集合中

我用Node.js和MongoDB使用sails web框架来创build我自己的网站。 现在，我在创build一个新用户时遇到了一些困难，并且在发送一个post请求的时候向我的'users'集合中插入了值（从不同的types：Number，Array，Object）。 我无法弄清楚，为什么这里唯一的types是'string'，当我改变types为'数字'例如，并通过邮递员发送一个post请求，这是popup的错误：

"message": "Resolver error: \"age\" has wrong type", "name": "PARAMETER_WRONG_TYPE", 

这是用户控制器：

 create: function(req, res){ var expectedInputs = [ { name: 'idsid', type: 'string', required: true } , { name: 'age', type: 'Number', required: true } , { name: 'last_name', type: 'string', required: true } ]; SanitizeService.allReqParams(req.allParams(), expectedInputs) .then(function(sanitizedInputs){ var user = {}; user.idsid = sanitizedInputs['idsid']; user.age = sanitizedInputs['age']; user.last_name = sanitizedInputs['last_name']; return UserService.create(user); }) .then(function(response){ res.ok(response); }) .catch(function(err){ res.badRequest(err); }); } 

这是在UserService中创build的函数：

 create: function(user) { return new P(function(resolve, reject){ sails.log.verbose('API Audit: UserService.create called'); var rejection = new Error('UserService.create Error: '); user.Created = new Date(); user.Modified = new Date(); Users.native(function(err, collection){ if(err){ rejection.message += 'problem connecting to collection'; return reject(rejection); } collection.update({'idsid': user.idsid}, user, {upsert: true}, function(err, results){ if(err){ rejection.message += err; return reject(rejection); } else { return resolve(results); } } ); }); }); } 

请让我知道，如果有什么需要了解这个问题。 感谢你的帮助！

编辑：如下build议，我试图改变types为“ 整数 ”，这是我得到的错误：

 "stack": "Error: Resolver error: wrong type \"integer\"\n at Resolver.addParameter (C:\\workspace\\node_modules\\input-resolver\\index.js:81:13)\n at C:\\workspace\\api\\services\\SanitizeService.js:57:15\n at Array.forEach (native)\n at C:\\workspace\\api\\services\\SanitizeService.js:5 

我不确定这是否有必要，但这是input分解器 ：

 function ResolverError(msg, name) { this.message = msg; this.name = name; } ResolverError.prototype = new Error(); function Resolver() { this.parameters = []; this.asPromise = false; } Resolver.types = ['string', 'boolean', 'number', 'object', 'array']; Resolver.checkType = function(param, type) { return type == 'array' ? Array.isArray(param) : typeof param === type; }; Resolver.prototype.asPromise = function(asPromise) { this.asPromise = (typeof asPromise == 'boolean') ? asPromise : true; }; Resolver.prototype.getParameter = function(name, parent) { if (!this.parameters.length) { return null; } parent = typeof parent == 'string' && '' != parent ? parent : null; for (var i = 0, len = this.parameters.length; i < len; i++) { if (name === this.parameters[i].name) { if (parent && parent != this.parameters[i].parent) continue; return this.parameters[i]; } } return null; }; Resolver.prototype.getAllParameters = function() { return this.parameters; }; Resolver.prototype.addParameter = function(param) { var checkParameter = function(param) { if (typeof param != 'object') { return false; } if (!param.name || typeof param.required != 'boolean') { return false; } return true; }; if (!checkParameter(param)) { throw new ResolverError( 'Resolver error: parameter not valid', 'PARAMETER_NOT_VALID' ); } var paramFound = this.getParameter(param.name, param.parent); if (null !== paramFound) { throw new ResolverError( 'Resolver error: trying to overwrite "' + param.name + '" parameter', 'PARAMETER_OVERWRITE' ); } var p = { name: param.name, required: param.required, parent: null }; if (typeof param.type != 'undefined') { if (Resolver.types.indexOf(param.type) == -1) { throw new Error('Resolver error: wrong type "' + param.type + '"'); } p.type = param.type; } if (typeof param.default != 'undefined') { if (p.required) { throw new Error( 'Resolver error: trying to set default value to required parameter' ); } if (p.type && !Resolver.checkType(param.default, p.type)) { throw new Error( 'Resolver error: default value doesn\'t match the param type' ); } p.default = param.default; } if (typeof param.values != 'undefined') { if (!Array.isArray(param.values)) { throw new Error('Resolver error: available values is not an array'); } if (!param.values.length) { throw new Error('Resolver error: available values array is empty'); } p.values = param.values; } if (typeof param.parent == 'string') { if ('' == param.parent) { throw new Error( 'Resolver error: parent property for "' + param.name + '" is an empty string' ); } var parentParam = this.getParameter(param.parent); if (null !== parentParam) { if (parentParam.type && parentParam.type != 'object') { throw new Error( 'Resolver error: parent for parameter "' + param.name + '"' + ' is defined, but has type of "' + parentParam.type + '" instead of' + ' "object"' ); } parentParam.type = 'object'; parentParam.required = true; } else { this.parameters.unshift({ name: param.parent, required: true, type: 'object', parent: null }); } p.parent = param.parent; } this.parameters.push(p); return this; }; Resolver.prototype._resolve = function(data, callback) { var getKeys = function(obj) { if (typeof obj != 'object') { return []; } var keys = []; for (var k in obj) { keys.push(k); } return keys; }; if (!this.parameters.length) { return callback( new ResolverError( 'Resolver error: no parameters specified', 'NO_RESOLVER_PARAMETERS' ) ); } if (!getKeys(data).length) { return callback( new ResolverError( 'Resolver error: empty data provided', 'EMPTY_DATA' ) ); } var resolved = {}; for (var i = 0; i < this.parameters.length; i++) { var param = this.parameters[i]; var parameterData = param.parent ? data[param.parent][param.name] : data[param.name] ; if (param.required) { if (typeof parameterData == 'undefined') { return callback( new ResolverError( 'Resolver error: "' + param.name + '" required parameter not found', 'NO_REQUIRED_PARAMETER' ) ); } } else { if ( typeof parameterData == 'undefined' && typeof param.default == 'undefined' ) { continue; } parameterData = typeof parameterData == 'undefined' ? param.default : parameterData; } if ( typeof param.type == 'string' && !Resolver.checkType(parameterData, param.type) ) { return callback( new ResolverError( 'Resolver error: "' + param.name + '" has wrong type', 'PARAMETER_WRONG_TYPE' ) ); } if (param.values && param.values.indexOf(parameterData) == -1) { return callback( new ResolverError( 'Resolver error: "' + param.name + '" has wrong value', 'PARAMETER_WRONG_VALUE' ) ); } if (param.parent) { resolved[param.parent][param.name] = parameterData; } else { resolved[param.name] = parameterData; } } return callback(null, resolved); }; Resolver.prototype.resolve = function(data, callback) { this._resolve(data, callback); }; Resolver.prototype.resolvePromise = function(inputData) { var _this = this; return new Promise(function(fulfill, reject) { _this._resolve(inputData, function(err, data) { if (err) return reject(err); return fulfill(data); }); }); }; module.exports = Resolver;

你必须使用帆mongo与mongo db交互，因为你提到这是一个帆项目。

Sails模型不提供Numbertypes，而是提供整数和浮点数。

Sails模型支持的数据types是：

• 串
• 文本
• 整数
• 浮动
• date
• 约会时间
• 布尔
• 二进制
• 排列
• JSON
• MEDIUMTEXT
• LONGTEXT
• OBJECTID

请检查此： http : //sailsjs.com/documentation/concepts/models-and-orm/attributes您可能想要更改从数字的types为int。
