微信支付开发(7) 收货地址共享接口V2

在这篇微信公众平台开发教程中，我们将介绍如何在网页中实现获取收货地址的功能。

收货地址共享接口在2016年4月13日进行过升级，2016年5月20日只能使用新接口，本教程为新版接口的教程！

本文分为以下二个部分：

生成JS-SDK权限验证签名
实现获取共享收货地址

一、微信JS-SDK

1. 获得Access Token

access token的获得方法在前面有介绍，详情见微信公众平台开发(26) ACCESS TOKEN

2. 获取jsapi_ticket

生成签名之前必须先了解一下jsapi_ticket，jsapi_ticket是公众号用于调用微信JS接口的临时票据。正常情况下，jsapi_ticket的有效期为7200秒，通过access_token来获取。由于获取jsapi_ticket的api调用次数非常有限，频繁刷新jsapi_ticket会导致api调用受限，影响自身业务，开发者必须在自己的服务全局缓存jsapi_ticket 。

参考以下文档获取access_token（有效期7200秒，开发者必须在自己的服务全局缓存access_token）：
用第一步拿到的access_token 采用http GET方式请求获得jsapi_ticket（有效期7200秒，开发者必须在自己的服务全局缓存jsapi_ticket），接口地址如下

https:<span style="color: #008000;">//</span><span style="color: #008000;">api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=ACCESS_TOKEN&type=jsapi</span>

成功返回如下JSON：

<span style="color: #000000;">{    </span><span style="color: #800000;">"</span><span style="color: #800000;">errcode</span><span style="color: #800000;">"</span>:<span style="color: #800080;">0</span><span style="color: #000000;">,    </span><span style="color: #800000;">"</span><span style="color: #800000;">errmsg</span><span style="color: #800000;">"</span>:<span style="color: #800000;">"</span><span style="color: #800000;">ok</span><span style="color: #800000;">"</span><span style="color: #000000;">,    </span><span style="color: #800000;">"</span><span style="color: #800000;">ticket</span><span style="color: #800000;">"</span>:<span style="color: #800000;">"</span><span style="color: #800000;">bxLdikRXVbTPdHSM05e5u5sUoXNKd8-41ZO3MhKoyN5OfkWITDGgnr2fwJ0m9E8NYzWKVZvdVtaUgWvsdshFKA</span><span style="color: #800000;">"</span><span style="color: #000000;">,    </span><span style="color: #800000;">"</span><span style="color: #800000;">expires_in</span><span style="color: #800000;">"</span>:<span style="color: #800080;">7200</span><span style="color: #000000;">}</span>

获得jsapi_ticket之后，就可以生成JS-SDK权限验证的签名了。

3. 签名算法实现

签名生成规则如下：参与签名的字段包括noncestr（随机字符串）, 有效的jsapi_ticket, timestamp（时间戳）, url（当前网页的URL，不包含#及其后面部分）。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。这里需要注意的是所有参数名均为小写字符。对string1作sha1加密，字段名和字段值都采用原始值，不进行URL 转义。

即signature=sha1(string1)。示例：

noncestr=<span style="color: #000000;">Wm3WZYTPz0wzccnWjsapi_ticket</span>=sM4AOVdWfPE4DxkXGEs8VMCPGGVi4C3VM0P37wVUCFvkVAy_90u5h9nbSlYy3-Sl-<span style="color: #000000;">HhTdfl2fzFy1AOcHKP7qgtimestamp</span>=<span style="color: #800080;">1414587457</span><span style="color: #000000;">url</span>=http:<span style="color: #008000;">//</span><span style="color: #008000;">mp.weixin.qq.com?params=value</span>

步骤1. 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：

jsapi_ticket=sM4AOVdWfPE4DxkXGEs8VMCPGGVi4C3VM0P37wVUCFvkVAy_90u5h9nbSlYy3-Sl-HhTdfl2fzFy1AOcHKP7qg&noncestr=Wm3WZYTPz0wzccnW&timestamp=<span style="color: #800080;">1414587457</span>&url=http:<span style="color: #008000;">//</span><span style="color: #008000;">mp.weixin.qq.com?params=value</span>

步骤2. 对string1进行sha1签名，得到signature：

0f9de62fce790f9a083d5c99e95740ceb90c27ed

完整代码如下

二、收货地址共享接口

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

2. 绑定域名

先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”。

3. 获取签名包

<span style="color: #000000;">php</span><span style="color: #0000ff;">require_once</span> "jssdk.php"<span style="color: #000000;">;</span><span style="color: #800080;">$jssdk</span> = <span style="color: #0000ff;">new</span> JSSDK("yourAppID", "yourAppSecret"<span style="color: #000000;">);</span><span style="color: #800080;">$signPackage</span> = <span style="color: #800080;">$jssdk</span>-><span style="color: #000000;">GetSignPackage();</span>?>

4. 引入JS文件

在需要调用JS接口的页面引入如下JS文件：

特别注意：JS-SDK版本需使用http://res.wx.qq.com/open/js/jweixin-1.1.0.js

<span style="color: #0000ff;"><span style="color: #800000;">script </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="http://res.wx.qq.com/open/js/jweixin-1.1.0.js"</span><span style="color: #0000ff;">></span><span style="color: #800000;">script</span><span style="color: #0000ff;">></span></span>

5.通过config接口注入权限验证配置

所有需要使用JS-SDK的页面必须先注入配置信息，否则将无法调用。

        <script><span style="color: #000000;">          wx.config({            debug: <span style="color: #0000ff;">false<span style="color: #000000;">,            appId: '<?php echo $signPackage["appId"];?>'<span style="color: #000000;">,            timestamp: <?php echo $signPackage["timestamp"];?><span style="color: #000000;">,            nonceStr: '<?php echo $signPackage["nonceStr"];?>'<span style="color: #000000;">,            signature: '<?php echo $signPackage["signature"];?>'<span style="color: #000000;">,            jsApiList: [              <span style="color: #008000;">//<span style="color: #008000;"> 所有要调用的 API 都要加到这个列表中                'checkJsApi'<span style="color: #000000;">,                'openAddress'<span style="color: #000000;">,              ]          });        </script>

5. 通过ready接口处理成功验证

需要在页面加载时就调用，需要把相关接口放在ready函数中调用来确保正确执行

wx.ready(<span style="color: #0000ff;">function</span><span style="color: #000000;"> () {});</span>

5.1 通过checkJsApi判断当前客户端版本是否支持分享参数自定义

<span style="color: #000000;"> wx.checkJsApi({                jsApiList: [                    </span>'openAddress'<span style="color: #000000;">,                ],                success: </span><span style="color: #0000ff;">function</span><span style="color: #000000;"> (res) {                    alert(JSON.stringify(res));                }            });</span>

5.3. 实现收货地址共享
