浏览器端获取短信验证码java实现——阿里云短信服务

需求：浏览器端输入手机号，获取验证码。点击登录，验证验证码是否输入错误、是否超时等情况，一旦校验通过，将用户数据保存到数据中（业务逻辑）。

前提：注册阿里用户，开通短信服务，申请key、秘钥、签名、短信模板。参考：https://help.aliyun.com/document_detail/55284.html?spm=a2c4g.11174283.3.2.8d482c42qxWRYA

实现：

1、pom.xml文件添加阿里云短信服务的依赖

<!--阿里云短信发送start-->
    <dependency>
      <groupId>com.aliyun</groupId>
      <artifactId>aliyun-java-sdk-core</artifactId>
      <version>4.0.</version>
    </dependency>
    <dependency>
      <groupId>com.aliyun</groupId>
      <artifactId>aliyun-java-sdk-dysmsapi</artifactId>
      <version>1.1.</version>
    </dependency>

    <!--阿里云短信发送end-->

此处可能会报错，官网也说了，好像这个版本的不是很稳定吧。异常可能是：

Java.lang.NoClassDefFoundError:com/aliyuncs/exceptions/ClientException

　　解决：

（1）方法一：检查lib文件下是否有aliyun-java-sdk-core包，没有的话就手动先添加上吧。

（2）方法二：将版本号改为3.3.1，即低版本

<dependency>
      <groupId>com.aliyun</groupId>
      <artifactId>aliyun-java-sdk-core</artifactId>
      <version>3.3.</version>
    </dependency>

2、下载官方demo，这个是发送短信的工具。

3、controller层

 /**
   * app登录，附加：验证码时效性
   * @param conditionStr
   * @return
   */
  @RequestMapping(value = "/anLogin", method = RequestMethod.POST)
  @ResponseBody

  public ResponseModel anLogin(@RequestBody String conditionStr){
    return androidLoginService.anLogin(conditionStr);
  }

  /**
   * 点击发送验证码
   * @param conditionStr
   * @return
   */
  @RequestMapping(value = "/getVerificationCode", method = RequestMethod.POST)
  @ResponseBody
  public ResponseModel getVerificationCode(@RequestBody String conditionStr) {
    return androidLoginService.getVerificationCode(conditionStr);
  }

4、service实现层

}

特别注意的是，此处我们使用的是session保存验证码的格式，浏览器会自动保存sessionId，我们则方便获取。换做app的话，就不一样了，因为移动端没有sessionId，需要我们传输数据时候讲sessionId先传到移动端，再在登录时候，利用移动端传输过来的sessionId获取目标session的值。下节出代码。
