最近項目須要上線支付寶小程序,同時須要走用戶的受權流程完成用戶信息的存儲,之前作過微信小程序的開發,本覺得實現受權的過程是很簡單的事情,可是再實現的過程當中仍是遇到了很多的坑,所以記錄一下實現的過程

這個方法是獲取用戶信息的接口方法,只須要傳入客戶端傳遞的code,就能夠獲取到用戶的完整信息html
這個方法是獲取支付寶接口的token的方法,是一個公用方法,後面全部的支付寶的口調用,均可以使用這個方法先獲取tokennode
考慮到會調用各個支付寶的接口,所以這裏封裝這個方法是爲了方便截取接口返回成功以後的信息,提升代碼的閱讀性數據庫
這個方法是爲了獲取公共的參數,包括版本號,編碼,appid,簽名類型等基礎業務參數json
這個方法是獲取簽名的內容,入參是一個數組,最後輸出的是參數的拼接字符串小程序
這個是構建api獨立的業務參數部分方法,businessParam參數是支付寶各個接口的業務參數部分(出去公共參數),$apiMethod是對應的接口的方法名稱,如獲取token的方法名爲alipay.system.oauth.token微信小程序
