eTower为每一个API客户提供一个API令牌和对应的密钥。密钥只用作MAC SHA-1签名，密钥不会在请求中进行传输。每一个请求必须包含身份认证信息以证实发送方的身份和权限。

入门

根据以下步骤快速完成身份认证。

第一步：获取 Token 和 Key

	测试环境		正式环境
1	Host	http://qa.etowertech.com	Host	http://cn.etowertech.com
2	Token	test5AdbzO5OEeOpvgAVXUFE0A	Token	请于集成商联系
3	Key	79db9e5OEeOpvgAVXUFWSD	key	请于集成商联系

第二步：添加请求报文头部信息

Request Headers
X-WallTech-Date	请求发送时间时间格式为 RFC1123 Format 格式：EEE, DD MM YYYY HH:MM:SS ZZZ 样例：Thu, 04 Nov 2021 03:39:28 GMT 注意：格林威治时间(GMT)，是北京时间(GMT+8)减去8小时。当服务器接收时间与发送时间相差15分钟以上，服务端拒绝请求。
Authorization	签名认证格式：WallTech <Token>:<Base64 Encoded HMAC SHA-1 Hash> 说明： <Token>：API 令牌 Token。 <Base64 Encoded HMAC SHA-1 Hash> ： Java代码描述：通过将API令牌Key，如Key=79db9e5OEeOpvgAVXUFWSD，使用SecretKeySpec类对Key进行HmacSHA1方式的加密，再初始化一个算法为HmacSHA1的Mac对象，然后使用key初始化这个Mac对象。最后将Mac对象处理为Byte，然后对其进行Base64转换操作。具体加密方式请参考：
Content-Type	application/json
Accept	application/json

第三步：开始您的API对接

您现在可以开始将 eTower API集成到您的测试/正式环境中。有关所有 API 操作的完整信息，请参阅通用 API 文档。如需技术帮助，请发送电子邮件至
