在淘宝小程序的框架下，ISV不能直接通过发起http请求的方式与外部服务通信。考虑到用户的实际需求，小程序云提供了一个专有的外联通道，通过云函数发起外部接口调用，所有的外联必须使用该方案执行。
开通云服务，通过云函数发起外联请求调用，云SDK版本 >= 1.1.3（建议：若外联调用失败，尝试把云函数文件夹下的 package.json文件内的 sdkversion 的版本改为 * ）
调用API前需要先申请调用白名单。
出网IP白名单： 203.119.241.* （目前从未变更过，有变更会提前发公告）
GET请求URL长度不得超过256字节，超过部分将会被截断；
POST请求，相对GET请求审核更严格，如无必要请使用GET，申请POST后，GET权限同步开通；
POST请求支持application/json和application/x-www-form-urlencoded两种格式，?传入body参数格式不同，详细见示例
申请时，请务必详细说明需要使用HTTP外联的业务场景和需求，以及需要申请该域名下传输的全部字段信息(包括post请求中的body参数信息），未经过申请的字段将被平台过滤，无法调通。
