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。

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
微信地址共享使用的数据字段包括：

  • 收货人姓名
  • 地区，省市区三级
  • 详细地址
  • 邮编
  • 联系电话

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。
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

 

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
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>&timestamp=<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>&timestamp=<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>

实现代码如下

 

四、获得收货地址

编辑并获取用户收货地址editAddress接口，在网页前端调用。
参数列表：

参数 必填 说明
appId 是 公众号appID
scope 是 填写“jsapi_address”，获得编辑地址权限
signType 是 签名方式，目前仅支持SHA1
addrSign 是 签名，由各参数一起参与签名生成
timeStamp 是 时间戳
nonceStr 是 随机字符串

调用方法如下

参数返回：

返回值 说明
err_msg edit_address：ok获取编辑收货地址成功
edit_address：fail获取编辑收货地址失败
username 收货人姓名
telNumber 收货人电话
addressPostalCode 邮编
proviceFirstStageName 国标收货地址第一级地址
addressCitySecondStageName 国标收货地址第二级地址
addressCountiesThirdStageName 国标收货地址第三级地址
addressDetailInfo 详细收货地址信息
nationalCode 收货地址国家码
