[1688开放平台](https://open.1688.com/)

#### 安装

使用npm:

```
npm i 1688-open-sdk -S
```

或者yarn:

```
yarn add 1688-open-sdk
```

#### 引入文件

```
import ApiExecutor from "1688-open-sdk"

或者

const ApiExecutor = require("1688-open-sdk")
```

#### 配置

使用1688开放平台的appkey，appsecret进行初始化:

```
const apiExecutor = new ApiExecutor(process.env.APPKEY, process.env.APPSECRET)
```

#### API

##### 使用 code 换取 refreshToken

```
const { refresh_token } = await apiExecutor.code2RefreshToken(code, redirect_uri)
```

##### 使用refreshToken更新AccessToken

```
const { access_token } = await apiExecutor.refreshToken2AccessToken(refresh_token)
```

例如 跨境产品以图搜图：

```
apiExecutor.execute(
    'com.alibaba.linkplus/alibaba.cross.similar.offer.search',
    {
        picUrl:'https://img.alicdn.com/imgextra/i1/O1CN01PwAoB21LuSuZE9Oqx_!!6000000001359-2-tps-1170-597.png',
        page: 1
    },
    access_token
)
```

注意调用api返回的都是promise，因此可使用async/await。

### 授权地址

```
https://auth.1688.com/oauth/authorize?client_id=appKey&site=1688&redirect_uri=http://www.baidu.com/&state=1
```

授权成功后会跳转到你设置的redirect_uri地址，并附带code和state参数。
