我正在使用irlnathan / ponzicoder的Sailscasts系列作为指南，开发一个网络应用程序。我已经为{＆＃39;用户＆＃39;}创建了条目Ep. 5。使用注册动作的模型。在本教程的这个阶段（链接的精确时间），我们看到他收到的响应页面是刚刚使用注册创建的User的JSON对象。但是，我在我的回复页面中得到以下信息：
{
"error": "E_VALIDATION",
"status": 400,
"summary": "1 attribute is invalid",
"model": "User",
"invalidAttributes": {
"encryptedPassword": [
{
"rule": "string",
"message": "`undefined` should be a string (instead of \"null\", which is a object)"
},
{
"rule": "required",
"message": "\"required\" validation rule failed for input: null"
}
]
}
}
这表明我的加密密码＆＃39;在我返回响应时，参数以某种方式未定义。但是，当我记录json对象时，我将返回到我的控制台中的响应，我得到以下内容（这是我期望看到的而不是E_VALIDATION响应）：
{ firstName: 'First',
lastName: 'Last',
email: 'email@domain.com',
encryptedPassword: '$2a$10$q0TfKWnN47mucsZLybN8WeygPPMpYxp9VMGUgIjA./ipZBn.POuOG',
lastLoggedIn: '2015-08-03T23:45:22.520Z',
gravatarUrl: 'http://www.gravatar.com/avatar/7328fddefd53de471baeb6e2b764f78a?',
createdAt: '2015-08-03T23:45:22.523Z',
updatedAt: '2015-08-03T23:45:22.523Z',
id: 39 }
所以encryptedPassword肯定是正确创建和定义的。
这是一个类似于 THIS 用户面临的问题，除了我的问题不在于缺少HTML名称属性。更奇怪的是，我的问题特别在于加密密码＆＃39;参数，没有其他参数。
我必须承认，由于我没有使用与我的注册表单完全相同的字段作为教程，因此可能存在一些导致问题的差异。但是，经过几个小时的调试后，我仍然无法弄明白。这就是我使用
的内容相关代码：
注册操作（UserController.js＆lt; - 遵循sails.js约定）
作为注册函数中散布的每个console.log语句的注释，我得到了所有的非null值。我这样做是为了验证确实encryptedPassword不是null / undefined
/**
* UserController
*
* @description :: Server-side logic for managing Users
* @help :: See http://sailsjs.org/#!/documentation/concepts/Controllers
*/
module.exports = {
signup: function(req, res) {
var Passwords = require('machinepack-passwords');
// Encrypt a string using the BCrypt algorithm.
Passwords.encryptPassword({
password: req.param('password')
// difficulty: 10,
}).exec({
// An unexpected error occurred.
error: function (err){
return res.negotiate(err);
},
// OK.
success: function (encryptedPassword){
console.log("1", encryptedPassword);
require('machinepack-gravatar').getImageUrl({
emailAddress: req.param('email')
}).exec({
error: function(err) {
return res.negotiate(err);
},
success: function(gravatarUrl) {
console.log("2", encryptedPassword);
console.log("2", gravatarUrl);
User.create({
firstName: req.param('firstName'),
lastName: req.param('lastName'),
email: req.param('email'),
encryptedPassword: encryptedPassword,
lastLoggedIn: new Date(),
gravatarUrl: gravatarUrl
}, function userCreated(err, newUser) {
console.log("NEWUSER", newUser);
console.log("3", encryptedPassword);
console.log("3", gravatarUrl);
if (err) {
console.log("err: ", err);
console.log("err.invalidAttributes: ", err.invalidAttributes)
// If this is a uniqueness error about the email attribute,
// send back an easily parseable status code.
if (err.invalidAttributes && err.invalidAttributes.email && err.invalidAttributes.email[0]
&& err.invalidAttributes.email[0].rule === 'unique') {
return res.emailAddressInUse(); //some error that I have already defined somewhere else in my project
}
return res.negotiate(err);
}
return res.json({
id: newUser.id
});
});
}
});
}
});
}
};
用户模型的属性（User.js＆lt; - 遵循sails.js约定）
/**
* User.js
*
* @description :: TODO: You might write a short summary of how this model works and what it represents here.
* @docs :: http://sailsjs.org/#!documentation/models
*/
module.exports = {
schema: true,
attributes: {
//all the other attributes
// The encrypted password for the user
encryptedPassword: {
type: 'string',
required: true
}
//more attributes
}
};
注册表单的HTML
<form ng-submit="submitSignupForm()" id="sign-up-form" name="signup" class="form" role="form">
<!-- irrelevant html -->
<!-- P A S S W O R D -->
<div class="control-group form-group" ng-class="{'has-error':signup.password.$invalid && signup.password.$dirty}">
<input type="password" name="password" value="" class="form-control input-lg" placeholder="Password" ng-model="signupForm.password" id="password" required ng-minlength="12"/>
<span class="help-block has-error" ng-if="signup.password.$dirty">
<span ng-show="signup.password.$error.required">Password is required.</span>
<span ng-show="signup.password.$error.minlength">Password must be at least 12 characters.</span>
</span>
</div>
<!-- more misc html -->
</form>
和注册控制器
angular.module('SignupModule').controller('SignupController', ['$scope', '$http', 'toastr', function($scope, $http, toastr) {
$scope.signupForm = {
loading: false
}
$scope.submitSignupForm = function() {
$scope.signupForm.loading = true;
console.log("clicked!");
$http.post('/signup', {
firstName: $scope.signupForm.firstName,
lastName: $scope.signupForm.lastName,
email: $scope.signupForm.email,
password: $scope.signupForm.password
})
.then(function onSuccess() {
window.location = '/user';
})
.catch(function onError(sailsResponse) {
var emailAddressAlreadyInUse = (sailsResponse.status == 409);
if (emailAddressAlreadyInUse) {
toastr.error('That email address has already been taken, please try again.', 'Error');
return;
}
})
.finally(function eitherWay() {
$scope.signupForm.loading = false;
});
}
}]);
重申一下，为什么地球上的encryptedPassword被解释为null？
