我尝试做的是将sailsjs应用程序的快速实施作为策略。
因此我注册了政策bruteForce。
我的bruteForce.js文件包含:
const ExpressBrute = require('express-brute'),
moment = require('moment'),
SequelizeStore = require('express-brute-sequelize'),
Sequelize = require('sequelize');
const failCallback = (req, res, next, nextValidRequestDate) => {
res.status(429).json({
message: 'You\'ve made too many failed attempts in a short period of time, please try again '+moment(nextValidRequestDate).fromNow(),
nextValidRequestDate,
tryAgainIn: moment(nextValidRequestDate).diff(moment)
})
}
const handleStoreError = (error) => {
sails.log.error(error);
throw {
message: error.message,
parent: error.parent
};
}
const store = new ExpressBrute.MemoryStore();
const bruteForceOptions = {
freeRetries: 3,
minWait: 1000*60,
maxWait: 1000*60*15,
failCallback,
handleStoreError
}
const bruteforce = new ExpressBrute(store, bruteForceOptions)
module.exports = async function (req, res, next) {
return bruteforce.prevent(req, res, next)
};
到目前为止这是有效的,但是当我尝试设置另一个商店驱动程序时 - 我现在选择了Sequelize驱动程序。
因此我补充说:
const sequelize = new Sequelize('table', 'root', 'secret', {
host: '127.0.0.1',
dialect: 'mysql',
operatorsAliases: false,
logging: sails.log.debug
});
const getBruteforce = async function(){
new SequelizeStore(sequelize, 'bruteStore', {}, function(store) {
console.log(store)
return new ExpressBrute(store, bruteForceOptions)
});
}
我的新政策功能是:
module.exports = async function (req, res, next) {
const bruteforce = await getBruteforce()
return bruteforce.prevent(req, res, next)
};
但是在这里我总是得到错误bruteforce undefined,然后在新SequelizeStore的回调中调用console.log。
我不明白我是如何解决的。
有人有想法吗?
答案 0 :(得分:1)
因为您的WKWebView
函数实际上没有返回任何内容。
getBruteforce()
执行此操作:
const getBruteforce = async function(){
new SequelizeStore(sequelize, 'bruteStore', {}, function(store) {
console.log(store)
// Below returns from the callback, **not** the async function
return new ExpressBrute(store, bruteForceOptions)
});
}
我建议您阅读有关如何return values from async functions的内容。
