今天接了一个小活，用asp写阿里云的机器翻译通用版api接口，本以为是小活，没想到搞一天，阿里云的api很变态，说说过程：
1、先看了《《RPC 调用机制》公共请求参数组装方案》，学会阿里云 RPC OpenAPI 向开发者提供的HTTP接口，来构造 HTTP 请求调用对应的 OpenAPI
2、又去了《阿里云 OpenAPI 开发者门户》找到API 版本
3、又去《RAM 控制台》搞AccessKeyId
4、又研究如何按照ISO8601标准表示，并需要使用 UTC时间去搞Timestamp
5、又研究HMAC-SHA1加密方式
6、然后在研究签名机制
7、又绕回去研究URL接口请求构造
8、为了适应他请求参数进行规范化编码。又学了参数编码方式，使用 UTF-8 字符集按照RFC3986规则进行编码
9、构造签名字符串又学了按照RFC2104的定义，用Base64() 为编码计算函数，HMAC_SHA1() 为 HMAC_SHA1 签名函数，返回值为 HMAC_SHA1 加密后原始字节，而非16进制字符串，UTF_8_Encoding_Of() 是 UTF-8 字符编码
10、通过各种文档，被他绕来绕去，终于成功写好：机器翻译通用版

搞了一整天，现在都快哭了，不说了，上代码吧
