网站或者移动端应用的手机验证码功能，现在应用到的地方非常多，但是具体实现都差不多，也比较简单，正好最近我们网站需要开发这么个功能。所以记录以下： 1 首先选择一家短信服务提供商，大概时六分一条吧，我们选择的是容联云通讯，然后他们会提供接口文档或者demo。 2 接口调用方式，可以使用http方式，就是直接在前端页面中访问某个url，并传入相关参数，也可以将jar文件添加导classpath，，然后使用他们demo里的类即可。使用http方式本质上还是调用远端的sdk，这里选择sdk方式。 3下边是页面上的一些js，主要控制点击后在过60s才可以再次点击。
{var telphone=$(“#tel”).val();if(telphone==””){alert(“请输入手机号”);return;}//1服务器端生成验证码$.post(sendTelCode(telphone,code);//3设置按钮不可用$(“#btnCode”).attr(“disabled”, “disabled”);setMyTimeout();});}{$.post((“success”==message){alert(“短信发送成功”);}else{alert(“短信发送失败”);}});}{$.post((“”!=code){var pageCode=$(“#code”).val();var telphone=$(“#tel”).val();var userId = $(“#userId”).val();if(“”==pageCode){alert(“请输入验证码”);return;}// if(pageCode==code){//修改数据库用户状态：手机已验证$.post((“success”==message){alert(“验证成功，保存配置后可以使用手机号登录了”);}else{alert(“短信验证失败”);}});}});}//设置定时器 var count = 60; {if (count > 0) {setTimeout(setMyTimeout, 1000);$(“#btnCode”).val((count–) + “秒之后点击获取”);}else {count=5;$(“#btnCode”).val(“点击获取验证码”);$(“#btnCode”).attr(“disabled”, “”);} }
2 对于服务器端： 主要生成验证码，发送验证码，不过短信模版需要自己上提供商网站操作。然后将应用id，模版id 账户传进去即可。
