建议采用异步的HTTP GET或POST(application/x-www-form-urlencoded)请求方式
设定合理的调用超时时间。如果在指定的时间内没有返回，结束HTTP请求
获取appKey和appSecret

以解密日志接入示例，详细说明日志接入步骤
a.准备请求参数(以UTF-8格式编码)
appKey=your appKey
time=2022-01-14 10:10:10
userId=your userId
userIp=your userIp
ati=your ati
decryptTime=2022-01-14 10:10:10
logTime=2022-01-14 10:10:10
topAppKey=your topAppKey
appName"=your appName
action=your action
orderId=your orderId
topRequestId=your topRequestId
url=your url
b.针对上面准备的参数按照key进行排序(升序)然后拼接字符串

将上面字符串中的红色字体替换成自己对应的值。最前面和最后面的you appSecret替换为自己的appsecret.
c.获取拼接字符串的utf-8编码字节序列，采用md5方式加密，再把加密后的字节转化为16进制，得到sign字符串。签名算法请参考示例代码。并在请求参数中添加sign得到的请求参数中，完整的请求链接如下所示
http://gw-ose.aliyun.com/event/Decrypt?appKey=68757219&sign=328a7d9a1bce2dbdddc7962f6a4ec828&time=2022-01-14 10:10:10&userId=your userId&userIp=your userIp&ati=your ati&decryptTime=2022-01-14 10:10:10&logTime=2022-01-14 10:10:10&topAppKey=your topAppKey&appName=your appName&action=your action&orderId=your orderId&topRequestId=your topRequestId&url=your url
d.使用POST方法请求服务
POST请求的ContentType设置为:application/x-www-form-urlencoded
e.API返回值
所有API返回json字符串，表示调用成功与否，格式如下：
{
"result":"success",
"errMsg":""
}
JAVA签名获取示例
public static void main(String[] args) throws Exception {
Map<String, String> requestParameters = new TreeMap<String, String>(String.CASE_INSENSITIVE_ORDER);
requestParameters.put("appKey", "you appKey");
requestParameters.put("time", "2022-01-14 10:10:10");
requestParameters.put("userId", "your userId");
requestParameters.put("userIp", "your userIp");
requestParameters.put("ati", "your ati");
requestParameters.put("decryptTime", "2022-01-14 10:10:10");
requestParameters.put("logTime", "2022-01-14 10:10:10");
requestParameters.put("topAppKey", "your topAppKey");
requestParameters.put("appName", "your appName");
requestParameters.put("action", "your action");
requestParameters.put("orderId", "your orderId");
requestParameters.put("topRequestId", "your topRequestId");
requestParameters.put("url", "your url");
String appSecret = "you appSecret";
StringBuilder stringBuilder = new StringBuilder();
// 针对上面准备的参数按照key进行排序(升序)然后拼接字符串
stringBuilder.append(appSecret);
Set<Entry<String, String>> entrySet = requestParameters.entrySet();
for (Entry<String, String> entry : entrySet) {
String val = entry.getValue();
stringBuilder.append(entry.getKey() + val);
}
stringBuilder.append(appSecret);
// 获取拼接字符串的UTF-8编码字节序列
byte[] bytesOfMessage = stringBuilder.toString().getBytes("UTF-8");
// 采用MD5方式编码
MessageDigest messageDigest = MessageDigest.getInstance("MD5");
byte[] thedigest = messageDigest.digest(bytesOfMessage);
// 再把编码后的字节转化为16进制，得到sign字符串
StringBuffer stringBuffer = new StringBuffer();
for (int i = 0; i < thedigest.length; i++) {
String temp = Integer.toHexString(thedigest[i] & 0xff);
if (temp.length() == 1) {
// 得到的一位的进行补0操作
stringBuffer.append("0");
}
stringBuffer.append(temp);
}
// 计算得出sign
System.out.println(stringBuffer.toString());
}
