使用OkHttp请求短信验证服务接口

使用OkHttp请求短信验证服务接口

最近在写比赛项目,登录,注册界面可能都会用到短信验证这个功能,其实这个功能后端并不难去实现,我们只需要满足对应服务商规定的API规则,请求接口给指定手机号发送验证码,然后再获取验证码加上手机号去请求 验证验证码的接口,就可以实现了.这里我用的是Bmob的短信验证服务

• 请求短信验证码
  
• 验证短信验证码
  

首先要在pom.xml中导入OkHttp和json转换相关的依赖

		<dependency>
            <groupId>com.squareup.okhttp</groupId>
            <artifactId>okhttp</artifactId>
            <version>2.5.0</version>
        </dependency>
		<dependency>
            <groupId>com.google.code.gson</groupId>
            <artifactId>gson</artifactId>
            <version>2.8.5</version>
        </dependency>

在后台创建PhoneUtil类,封装相关方法

public class PhoneUtil {

    private final static ObjectMapper MAPPER = new ObjectMapper();

    public static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
    /**
     * 获取手机验证码
     * @param phoneNumber
     * @return
     */
    public static String getVerificationCode(String phoneNumber) {
        System.out.println(phoneNumber);
        String url = "https://api2.bmob.cn/1/requestSmsCode";
        OkHttpClient client = new OkHttpClient();

        PhoneRequest phoneRequest = new PhoneRequest(phoneNumber,"AppModel");


        Gson gson = new Gson();
        String json = gson.toJson(phoneRequest);
        System.out.println(json);
        RequestBody  jsonBody = RequestBody.create(JSON,json);


        Request request = new Request.Builder()
                .url(url)
                .addHeader("X-Bmob-Application-Id","4527189a38e9393bebbaaf3940982580")
                .addHeader("X-Bmob-REST-API-Key","6449d52f810bf605698ff865f5017929")
                .addHeader("Content-Type","application/json")
                .post(jsonBody)
                .build();

        try {
            Response response = client.newCall(request).execute();
            String result = response.body().string();
            System.out.println("获取到响应:" + result);
            System.out.println("开始请求....");
            if ( !response.isSuccessful()) {
                System.out.println("请求失败...");
                return null;
            }
            System.out.println("请求成功...");
            System.out.println("获取到响应:" + result);
            return bodyToJson(result);

        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }


    /**
     * 验证用户验证码是否正确
     * @param code
     * @return
     */
    public static boolean judgeCodeIsTrue(String code,String mobilePhoneNumber) {
        String url = "https://api2.bmob.cn/1/verifySmsCode/" + code;
        OkHttpClient client = new OkHttpClient();


        PhoneNumber phoneNumber = new PhoneNumber(mobilePhoneNumber);

        Gson gson = new Gson();
        String json = gson.toJson(phoneNumber);
        System.out.println(json);
        RequestBody  jsonBody = RequestBody.create(JSON,json);


        Request request = new Request.Builder()
                .url(url)
                .addHeader("X-Bmob-Application-Id","4527189a38e9393bebbaaf3940982580")
                .addHeader("X-Bmob-REST-API-Key","6449d52f810bf605698ff865f5017929")
                .addHeader("Content-Type","application/json")
                .post(jsonBody)
                .build();

        try {
            Response response = client.newCall(request).execute();
            String result = response.body().string();
            System.out.println("获取到响应:" + result);
            System.out.println("开始请求....");
            if ( !response.isSuccessful()) {
                System.out.println("请求失败...");
                return false;
            }
            System.out.println("请求成功...");
            System.out.println("获取到响应:" + result);
            return true;

        } catch (IOException e) {
            e.printStackTrace();
        }
        return false;
    }

    /**
     * 请求体转Json
     * @param result
     * @return
     */
    private static String bodyToJson(String result) {

        JsonNode root = null;
        try {
            root = MAPPER.readTree(result);
        } catch (IOException e) {
            e.printStackTrace();
        }

        JsonNode code = root.path("smsId");
        System.out.println("验证码:"+code);
        return code.toString();
    }

}

首先这里要注意的第一个就是,文档要求请求体是application/json;格式,所以我们需要导入json转化相关的jar来将请求体中的数据转化为json格式,再发送请求.

然后就是OkHttp中 请求的发送和响应的接收了:

//新建OkHttpClient对象
OkHttpClient client = new OkHttpClient();

//新建request
Request request = new Request.Builder()
                .url(url)
                .addHeader("X-Bmob-Application-Id","4527189a38e9393bebbaaf3940982580")
                .addHeader("X-Bmob-REST-API-Key","6449d52f810bf605698ff865f5017929")
                .addHeader("Content-Type","application/json")
                .post("相关数据")
                .build();

我们首先需要知道所请求的url,紧接着可以使用addHeader()方法去加入请求头信息,这里我们是以post方式放松的,参数中可以填上相关请求体数据(RequestBody类型).在Request对象build好之后,就可以调用OkHttpClient对象的newCall()方法,并excute().就可以获取响应了

除此之外,OkHttp还可以以Get的方式请求接口,也可以Post提交表单,字符串,流数据等.还有一些异步,同步的方式,这些以后再细看
