调用网易云短信验证码接口Demo

  最近在开发新的项目,因为需要使用验证码验证这个功能。我选择的是 网易云 的验证码接口。免费使用20条。并且在正式使用的过程中,对比了很多家以后,感觉还是他家的便宜。因为随着你购买的短信包数量的增加,价钱会相应的降低,下发的效率挺高的。

  官方给出的demo已经是很完美了,但是我总有中使用最新插件的强迫症,随着插件的更新,可能有些函数已经被废弃或者将要废弃。给出我写的一个demo。

SendCode.java (调用成功以后,返回的json串中,obj字段对应的值即下发的内容)

public class SendCode {
    public static String send(String mobile) throws Exception {
        CloseableHttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost httpPost = new HttpPost(NeteaseConsts.SERVER_URL);
        String curTime = String.valueOf((new Date()).getTime() / 1000L);
        String nonce = CreateUUID.getUUID();
        String checkSum = CheckSumBuilder.getCheckSum(NeteaseConsts.APP_SECRET, nonce, curTime);

        // 设置请求的header
        httpPost.addHeader("AppKey", NeteaseConsts.APP_KEY);
        httpPost.addHeader("Nonce", nonce);
        httpPost.addHeader("CurTime", curTime);
        httpPost.addHeader("CheckSum", checkSum);
        httpPost.addHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");

        // 设置请求的的参数,requestBody参数
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("mobile", mobile));
        nvps.add(new BasicNameValuePair("codeLen", NeteaseConsts.CODELEN));

        httpPost.setEntity(new UrlEncodedFormEntity(nvps, "utf-8"));

        // 执行请求
        HttpResponse response = httpClient.execute(httpPost);

        String resultStr = EntityUtils.toString(response.getEntity(), "utf-8");
        if (!StringUtils.isEmpty(resultStr)) {
            JsonObject resultData = new JsonParser().parse(resultStr).getAsJsonObject();
            String code = resultData.get("code").getAsString();
            if ("200".equals(code)) {
                String obj = resultData.get("obj").getAsString();
                return obj;
            }
        }
        return "";
    }
}

CheckSumBuilder.java(官方给出的sha1加密方案,已经是写好的)

public class CheckSumBuilder {
    public static String getCheckSum(String appSecret, String nonce, String curTime) {
        return encode("sha1", appSecret + nonce + curTime);
    }

    // 计算并获取md5值
    public static String getMD5(String requestBody) {
        return encode("md5", requestBody);
    }

    private static String encode(String algorithm, String value) {
        if (value == null) {
            return null;
        }
        try {
            MessageDigest messageDigest
                    = MessageDigest.getInstance(algorithm);
            messageDigest.update(value.getBytes());
            return getFormattedText(messageDigest.digest());
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    private static String getFormattedText(byte[] bytes) {
        int len = bytes.length;
        StringBuilder buf = new StringBuilder(len * 2);
        for (int j = 0; j < len; j++) {
            buf.append(HEX_DIGITS[(bytes[j] >> 4) & 0x0f]);
            buf.append(HEX_DIGITS[bytes[j] & 0x0f]);
        }
        return buf.toString();
    }

    private static final char[] HEX_DIGITS = { '0', '1', '2', '3', '4', '5',
            '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f' };
}

NeteaseConsts.java (自己写的静态类,专门放置一些固定参数)

public class NeteaseConsts {
    public static final String SERVER_URL = "https://api.netease.im/sms/sendcode.action";
    public static final String APP_KEY = "XXXXXXXXXXXXXXXXXXXXXXXXX";
    public static final String APP_SECRET = "XXXXXXXXXXXXXXX";
    public static final String CODELEN = "6";
}

pom.xml(搭配的gson版本,以及httpcore、httpclient版本信息)

    <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
