#### 介绍
七牛云图片合成服务

#### 获取api key
**请求URL：** 
- ` http://xx.com/graph/token`
  
**请求方式：**
- GET 

**参数：** 

|参数名|必选|类型|说明|
|:----    |:---|:----- |-----   |
|signature |是  |string |签名   |

 **返回示例**
 
 ```
 {
     "code": "000",
     "message": "success",
     "data": {
         "api_key": "dc3d5706-a9c4-439f-bf27-03ef7a7d427a"
     }
 }
 ```
 
 **返回参数说明** 
 
 |参数名|类型|说明|
 |:-----  |:-----|-----                           |
 |api_key |string   |交互携带密钥(有效期2小时) |
 
 **签名生成算法说明**
 
 第一步: 将服务器ip地址(ip_addr) 约定盐值(salt) 当日零点时间戳(unix_time) 按顺序拼接得到 字符串1(string1)
 
 string1 = ip_addr+salt+unix_time
 
 第二步: 将string1用sha1算法加密得到签名signature
