【Java】通过调用阿里云短信服务给手机发短信

1.先到阿里云的云市场购买短信服务，一般会提供免费调用次数，大概十几二十次

2.下滑查看API接口详情

3.编写代码调用该接口

3.1 导入依赖

        <!--阿里云sdk-->
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
            <version>4.5.3</version>
        </dependency>
        <!--fastjson-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.47</version>
        </dependency>

        <!--httpClient-->
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.2.1</version>
        </dependency>

        <!--redis相关依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

3.2 接口配置(根据你购买的短信服务填写)

3.3 appcode在控制台复制

3.4 代码示例

Controller

     /**
     * 
     * @param sendCodeDTO （type 发送验证码类型  1-注册 2-登录，3-修改手机号）
     * @return
     */
    @PostMapping("/sendCode")
    @ApiOperation("发送短信验证码")
    public CommonResult sendCode(@RequestBody SendCodeDTO sendCodeDTO) {
        return userService.sendCode(sendCodeDTO);
    }

SendCodeDTO

@Data
public class SendCodeDTO {
    /**
     * 手机号
     */
    private String phone;
    /**
     * 验证码类型 ： 1-注册，2-登录，3-修改手机号
     */
    private Integer type;

}

CodeTypeEnum（验证码类型枚举）

public enum CodeTypeEnum {

    /**
     * 验证码类型 ： 1-注册，2-登录，3-修改手机号
     */

    REGISTER(1,"REGISTER"),
    LOGIN(2,"LOGIN"),
    EDIT(3,"EDIT");

    public static String getDescriptionByCode(Integer code){
        for(CodeTypeEnum value : CodeTypeEnum.values()){
            if(value.getCode().equals(code)){
                return value.getDesc();
            }
        }
        return null;
    }


    CodeTypeEnum(Integer code, String desc) {
        this.code = code;
        this.desc = desc;
    }

    private final Integer code;
    private final String desc;

    public Integer getCode() {
        return code;
    }

    public String getDesc() {
        return desc;
    }

}

（单纯发个短信验证码的话照着API文档的请求示例就可以实现了,需要根据验证码做处理的话，一般得存到Redis中）
