请看新版教程 微信支付开发(7) 收货地址共享接口V2
本文介绍微信支付下的收货地址共享接口的开发过程。
微信收货地址共享,是指用户在微信浏览器内打开网页,填写过地址后,后续可以免填写支持快速选择,也可增加和编辑。此地址为用户属性,可在各商户的网页中共享使用。支持原生控件填写地址,地址数据会传递到商户。
地址共享是基于微信JavaScript API 实现,只能在微信内置浏览器中使用,其他浏览器调用无效。同时,需要微信5.0 版本才能支持,建议通过user agent 来确定用户当前的版本号后再调用地址接口。以iPhone 版本为例,可以通过useragent可获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 为用户安装的微信版本号,商户可以判定版本号是否高于或者等于5.0。
地址格式
微信地址共享使用的数据字段包括:
其中,地区对应是国标三级地区码,如“广东省-广州市-天河区”,对应的邮编是是510630。详情参考链接:http://www.stats.gov.cn/tjsj/tjbz/xzqhdm/201401/t20140116_501070.html
获取收货地址之前前需要调用 登录授权接口获取到一次OAuth2.0的Access Token 。所以需要做一次授权,这次授权是不弹出确认框的。
其实质就是在用户访问
http:<span style="color: #008000;">//</span><span style="color: #008000;">www.fangbei.org/wxpay/js_api_call.php</span>
时跳转到
https:<span style="color: #008000;">//</span><span style="color: #008000;">open.weixin.qq.com/connect/oauth2/authorize?appid=wx8888888888888888&redirect_uri=http://www.fangbei.org/wxpay/js_api_call.php&response_type=code&scope=snsapi_base&state=STATE#wechat_redirect</span>
以此来获得code参数,并根据code来获得授权access_token及openid,这个access token将用于收货地址共享接口。
其实现的详细流程可参考 微信公众平台开发(71)OAuth2.0网页授权
生成随机字符串的方法如下
参与addrSign 签名的字段包括:appId、url(调用JavaScript API的网页url)、timestamp、noncestr、accessToken
对所有待签名参数按照字段名的ASCII 码从小到大排序(字典序)后,使用URL 键值对的格式(即key1=value1&key2=value2…)拼接成字符串string1。
这里需要注意的是签名过程中所有参数名均为小写字符,例如appId 在排序后字符串则为appid;
对string1作签名算法,字段名和字段值都采用原始值,不进行URL 转义。具体签名算法为addrSign = SHA1(string1)。这里给出生成addrSign 的具体示例如下:
appId=<span style="color: #000000;">wx17ef1eaef46752cb url</span>=http:<span style="color: #008000;">//</span><span style="color: #008000;">open.weixin.qq.com/</span> timeStamp=<span style="color: #800080;">1384841012</span><span style="color: #000000;"> nonceStr</span>=<span style="color: #800080;">123456</span><span style="color: #000000;"> accessToken</span>=OezXcEiiBSKSxW0eoylIeBFk1b8VbNtfWALJ5g6aMgZHaqZwK4euEskSn78Qd5pLsfQtuMdgmhajVM5QDm24W8X3tJ18kz5mhmkUcI3RoLm7qGgh1cEnCHejWQo8s5L3VvsFAdawhFxUuLmgh5FRA
i:经过a过程键值对排序后得到string1 为:
accesstoken=OezXcEiiBSKSxW0eoylIeBFk1b8VbNtfWALJ5g6aMgZHaqZwK4euEskSn78Qd5pLsfQtuMdgmhajVM5QDm24W8X3tJ18kz5mhmkUcI3RoLm7qGgh1cEnCHejWQo8s5L3VvsFAdawhFxUuLmgh5FRA&appid=wx17ef1eaef46752cb&noncestr=<span style="color: #800080;">123456</span>×tamp=<span style="color: #800080;">1384841012</span>&url=http:<span style="color: #008000;">//</span><span style="color: #008000;">open.weixin.qq.com/?code=CODE&state=STATE</span>
ii:经过b过程签名后可得到:
addrSign=SHA1(accesstoken=<span style="color: #000000;">OezXcEiiBSKSxW0eoylIeBFk1b8VbNtfWALJ5g6aMgZHaqZwK4euEskSn78Qd5pLsfQtuMdgmhajVM5QDm24W8X3tJ18kz5mhmkUcI3RoLm7qGgh1cEnCHejWQo8s5L3VvsFAdawhFxUuLmg h5FRA</span>&appid=wx17ef1eaef46752cb&noncestr=<span style="color: #800080;">123456</span>×tamp=<span style="color: #800080;">1384841012</span>&url=http:<span style="color: #008000;">//</span><span style="color: #008000;">open.weixin.qq.com/?code=CODE&state=STATE)=ca604c740945587544a9cc25e58dd090f200e6fb</span>
