语音服务的请求签名有哪些？

tring()); public static String sign(String accessSecret, String stringToSign) throws Exception { javax.crypto.Mac mac = javax.crypto.Mac.getInstance("HmacSHA1"); mac.init(new javax.crypto.spec.SecretKeySpec(accessSecret.getBytes("UTF-8"), "HmacSHA1")); byte[] signData = mac.doFinal(stringToSign.getBytes("UTF-8")); return new sun.misc.BASE64Encoder().encode(signData); }

参数说明：

accessSecret：您的AccessKeyId对应的秘钥AccessSecret，特别说明：POP要求需要后面多加一个“&”字符，即accessSecret + “&”。
stringToSign：即第三步生成的待签名请求串。

签名后的结果打印如下：

aMfgrx8DLS7vLfpeR1c2rrKLr0Q=

步骤五：增加签名结果到请求参数中，发送请求 说明 签名也要做特殊URL编码。

String Signature = specialUrlEncode(sign);// aMfgrx8DLS7vLfpeR1c2rrKLr0Q%3D

最终完整的GET请求HTTP为：

http://dyvmsapi.aliyuncs.com/?Signature=aMfgrx8DLS7vLfpeR1c2rrKLr0Q%3D&AccessKeyId=testId&Action=SingleCallByTts&CalledNumber=13000000000&CalledShowNumber=057112345678&Format=XML&OutId=123&RegionId=cn-hangzhou&SignatureMethod=HMAC-SHA1&SignatureNonce=f7d2d4ef-6d5f-4da4-86ed-88e001a66abb&SignatureVersion=1.0&Timestamp=2017-09-28T14%3A31%3A56Z&TtsCode=TTS_0000000&TtsParam=%7B%22code%22%3A%221234%22%2C%22product%22%3A%22test%22%7D&Version=2017-05-25
