Java實(shí)現(xiàn)發(fā)送短信驗(yàn)證碼+redis限制發(fā)送的次數(shù)功能
更新時(shí)間：2022年04月18日 14:25:15 作者：IamaMartian
這篇文章主要介紹了Java實(shí)現(xiàn)發(fā)送短信驗(yàn)證碼+redis限制發(fā)送的次數(shù),本文通過(guò)示例代碼給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下
java實(shí)現(xiàn)短信驗(yàn)證碼發(fā)送，由于我們使用第三方平臺(tái)進(jìn)行驗(yàn)證碼的發(fā)送，所以首先，我們要在一個(gè)平臺(tái)進(jìn)行注冊(cè)。這樣的平臺(tái)有很多，有的平臺(tái)在新建賬號(hào)的時(shí)候會(huì)附帶贈(zèng)幾條免費(fèi)短信。這里我僅做測(cè)試使用(具體哪個(gè)平臺(tái)見(jiàn)參考三，很簡(jiǎn)單，注冊(cè)賬號(hào)就行，記得添加短信簽名)。
另外，在實(shí)際項(xiàng)目中，如果有人惡意攻擊，不停的發(fā)送短信驗(yàn)證碼，就會(huì)造成很大的損失。故對(duì)發(fā)送次數(shù)做一定的限制就非常必要，這里我們限制一個(gè)手機(jī)號(hào)一天可以發(fā)多少短信和短信平臺(tái)無(wú)關(guān)。
這里采用的是存redis來(lái)實(shí)現(xiàn)這一個(gè)功能。就是每次調(diào)用發(fā)送驗(yàn)證碼這個(gè)接口都會(huì)判斷手機(jī)號(hào)碼是否在redis中存為key了。如果沒(méi)有則創(chuàng)建一個(gè)key為手機(jī)號(hào)碼value是1.因?yàn)閞edis中不支持?jǐn)?shù)字所以將其變?yōu)榱藄tring類型。如果redis中已經(jīng)有這個(gè)key了則將此key的值取出來(lái)加1再存進(jìn)redis中。

項(xiàng)目結(jié)果如下：
結(jié)果展示：
使用postman調(diào)用接口，超過(guò)2次后，顯示如下。
在具體項(xiàng)目中的流程一般如下：
①構(gòu)造手機(jī)驗(yàn)證碼，需要生成一個(gè)6位的隨機(jī)數(shù)字串；
②找短信平臺(tái)獲取使用接口向短信平臺(tái)發(fā)送手機(jī)號(hào)和驗(yàn)證碼，然后短信平臺(tái)再把驗(yàn)證碼發(fā)送到制定手機(jī)號(hào)上；
③將手機(jī)號(hào)驗(yàn)證碼、操作時(shí)間存入Session中，作為后面驗(yàn)證使用；
④接收用戶填寫(xiě)的驗(yàn)證碼、手機(jī)號(hào)及其他注冊(cè)數(shù)據(jù)；
⑤對(duì)比提交的驗(yàn)證碼與Session中的驗(yàn)證碼是否一致，同時(shí)判斷提交動(dòng)作是否在有效期內(nèi)；
⑥驗(yàn)證碼正確且在有效期內(nèi)，請(qǐng)求通過(guò)，處理相應(yīng)的業(yè)務(wù)。
