WeChat Pay develops delivery address sharing interface
Mar 06, 2017 am 10:10 AM本文介紹微信支付下的收貨地址共享接口的開發(fā)過程。
一. 簡(jiǎn)介
微信收貨地址共享,是指用戶在微信瀏覽器內(nèi)打開網(wǎng)頁(yè),填寫過地址后,后續(xù)可以免填寫支持快速選擇,也可增加和編輯。此地址為用戶屬性,可在各商戶的網(wǎng)頁(yè)中共享使用。支持原生控件填寫地址,地址數(shù)據(jù)會(huì)傳遞到商戶。
地址共享是基于微信JavaScript API 實(shí)現(xiàn),只能在微信內(nèi)置瀏覽器中使用,其他瀏覽器調(diào)用無效。同時(shí),需要微信5.0 版本才能支持,建議通過user agent 來確定用戶當(dāng)前的版本號(hào)后再調(diào)用地址接口。以iPhone 版本為例,可以通過useragent可獲取如下微信版本示例信息:"Mozilla/5.0(iphone;CPU iphone OS 5_1_1 like Mac OS X)AppleWebKit/534.46(KHTML,like Geocko) Mobile/9B206MicroMessenger/5.0"其中5.0 為用戶安裝的微信版本號(hào),商戶可以判定版本號(hào)是否高于或者等于5.0。
地址格式
微信地址共享使用的數(shù)據(jù)字段包括:
收貨人姓名
地區(qū),省市區(qū)三級(jí)
詳細(xì)地址
郵編
聯(lián)系電話
其中,地區(qū)對(duì)應(yīng)是國(guó)標(biāo)三級(jí)地區(qū)碼,如“廣東省-廣州市-天河區(qū)”,對(duì)應(yīng)的郵編是是510630。詳情參考鏈接:http://www.stats.gov.cn/tjsj/tjbz/xzqhdm/201401/t20140116_501070.html
?
二. OAuth2.0授權(quán)
獲取收貨地址之前前需要調(diào)用 登錄授權(quán)接口獲取到一次OAuth2.0的Access Token 。所以需要做一次授權(quán),這次授權(quán)是不彈出確認(rèn)框的。
其實(shí)質(zhì)就是在用戶訪問
http://www.fangbei.org/wxpay/js_api_call.php
時(shí)跳轉(zhuǎn)到
https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx8888888888888888&redirect_uri=http://m.miracleart.cn/
以此來獲得code參數(shù),并根據(jù)code來獲得授權(quán)access_token及openid,這個(gè)access token將用于收貨地址共享接口。
其實(shí)現(xiàn)的詳細(xì)流程可參考?微信公眾平臺(tái)開發(fā)OAuth2.0網(wǎng)頁(yè)授權(quán)

二、獲取隨機(jī)字符串
生成隨機(jī)字符串的方法如下
?
三、生成簽名
參與addrSign 簽名的字段包括:appId、url(調(diào)用JavaScript API的網(wǎng)頁(yè)url)、timestamp、noncestr、accessToken
對(duì)所有待簽名參數(shù)按照字段名的ASCII 碼從小到大排序(字典序)后,使用URL 鍵值對(duì)的格式(即key1=value1&key2=value2…)拼接成字符串string1。
這里需要注意的是簽名過程中所有參數(shù)名均為小寫字符,例如appId 在排序后字符串則為appid;
對(duì)string1作簽名算法,字段名和字段值都采用原始值,不進(jìn)行URL 轉(zhuǎn)義。具體簽名算法為addrSign = SHA1(string1)。這里給出生成addrSign 的具體示例如下:
appId=wx17ef1eaef46752cb url=http://open.weixin.qq.com/ timeStamp=1384841012 nonceStr=123456 accessToken=OezXcEiiBSKSxW0eoylIeBFk1b8VbNtfWALJ5g6aMgZHaqZwK4euEskSn78Qd5pLsfQtuMdgmhajVM5QDm24W8X3tJ18kz5mhmkUcI3RoLm7qGgh1cEnCHejWQo8s5L3VvsFAdawhFxUuLmgh5FRA
i:經(jīng)過a過程鍵值對(duì)排序后得到string1 為:
accesstoken=OezXcEiiBSKSxW0eoylIeBFk1b8VbNtfWALJ5g6aMgZHaqZwK4euEskSn78Qd5pLsfQtuMdgmhajVM5QDm24W8X3tJ18kz5mhmkUcI3RoLm7qGgh1cEnCHejWQo8s5L3VvsFAdawhFxUuLmgh5FRA&appid=wx17ef1eaef46752cb&noncestr=123456×tamp=1384841012&url=http://open.weixin.qq.com/?code=CODE&state=STATE
ii:經(jīng)過b過程簽名后可得到:
addrSign=SHA1(accesstoken=OezXcEiiBSKSxW0eoylIeBFk1b8VbNtfWALJ5g6aMgZHaqZwK4euEskSn78Qd5pLsfQtuMdgmhajVM5QDm24W8X3tJ18kz5mhmkUcI3RoLm7qGgh1cEnCHejWQo8s5L3VvsFAdawhFxUuLmg h5FRA&appid=wx17ef1eaef46752cb&noncestr=123456×tamp=1384841012&url=http://open.weixin.qq.com/?code=CODE&state=STATE)=ca604c740945587544a9cc25e58dd090f200e6fb
實(shí)現(xiàn)代碼如下
四、獲得收貨地址
編輯并獲取用戶收貨地址editAddress接口,在網(wǎng)頁(yè)前端調(diào)用。
參數(shù)列表:
參數(shù) | 必填 | 說明 |
---|---|---|
appId | 是 | 公眾號(hào)appID |
scope | 是 | 填寫“jsapi_address”,獲得編輯地址權(quán)限 |
signType | 是 | 簽名方式,目前僅支持SHA1 |
addrSign | 是 | 簽名,由各參數(shù)一起參與簽名生成 |
timeStamp | 是 | 時(shí)間戳 |
nonceStr | 是 | 隨機(jī)字符串 |
調(diào)用方法如下
參數(shù)返回:
返回值 | 說明 |
---|---|
err_msg | edit_address:ok獲取編輯收貨地址成功 |
edit_address:fail獲取編輯收貨地址失敗 | |
username | 收貨人姓名 |
telNumber | 收貨人電話 |
addressPostalCode | 郵編 |
proviceFirstStageName | 國(guó)標(biāo)收貨地址第一級(jí)地址 |
addressCitySecondStageName | 國(guó)標(biāo)收貨地址第二級(jí)地址 |
addressCountiesThirdStageName | 國(guó)標(biāo)收貨地址第三級(jí)地址 |
addressDetailInfo | 詳細(xì)收貨地址信息 |
nationalCode | 收貨地址國(guó)家碼 |
