微信支付开发收货地址共享接口
本文介绍微信支付下的收货地址共享接口的开发过程。一. 简介微信收货地址共享,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
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
二. OAuth2.0授权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。 http://www.fangbei.org/wxpay/js_api_call.php 时跳转到 https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx8888888888888888&redirect_uri=http://www.php.cn/ 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OAuth2.0网页授权
二、获取随机字符串生成随机字符串的方法如下
三、生成签名参与addrSign 签名的字段包括:appId、url(调用JavaScript API的网页url)、timestamp、noncestr、accessToken appId=wx17ef1eaef46752cburl=http://open.weixin.qq.com/timeStamp=1384841012nonceStr=123456accessToken=OezXcEiiBSKSxW0eoylIeBFk1b8VbNtfWALJ5g6aMgZHaqZwK4euEskSn78Qd5pLsfQtuMdgmhajVM5QDm24W8X3tJ18kz5mhmkUcI3RoLm7qGgh1cEnCHejWQo8s5L3VvsFAdawhFxUuLmgh5FRA i:经过a过程键值对排序后得到string1 为: accesstoken=OezXcEiiBSKSxW0eoylIeBFk1b8VbNtfWALJ5g6aMgZHaqZwK4euEskSn78Qd5pLsfQtuMdgmhajVM5QDm24W8X3tJ18kz5mhmkUcI3RoLm7qGgh1cEnCHejWQo8s5L3VvsFAdawhFxUuLmgh5FRA&appid=wx17ef1eaef46752cb&noncestr=123456×tamp=1384841012&url=http://open.weixin.qq.com/?code=CODE&state=STATE ii:经过b过程签名后可得到: addrSign=SHA1(accesstoken=OezXcEiiBSKSxW0eoylIeBFk1b8VbNtfWALJ5g6aMgZHaqZwK4euEskSn78Qd5pLsfQtuMdgmhajVM5QDm24W8X3tJ18kz5mhmkUcI3RoLm7qGgh1cEnCHejWQo8s5L3VvsFAdawhFxUuLmgh5FRA&appid=wx17ef1eaef46752cb&noncestr=123456×tamp=1384841012&url=http://open.weixin.qq.com/?code=CODE&state=STATE)=ca604c740945587544a9cc25e58dd090f200e6fb 实现代码如下
