微信支付开发(7) 收货地址共享接口V2，v2

关键字：微信公众平台 JSSDK 发送给朋友收货地址共享接口 openAddress
作者：方倍工作室
原文：http://www.cnblogs.com/txw1958/p/weixin-openaddress.html

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：

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>//</span><span>api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=ACCESS_TOKEN&type=jsapi</span>

成功返回如下JSON：

<span>{
    </span><span>"</span><span>errcode</span><span>"</span>:<span>0</span><span>,
    </span><span>"</span><span>errmsg</span><span>"</span>:<span>"</span><span>ok</span><span>"</span><span>,
    </span><span>"</span><span>ticket</span><span>"</span>:<span>"</span><span>bxLdikRXVbTPdHSM05e5u5sUoXNKd8-41ZO3MhKoyN5OfkWITDGgnr2fwJ0m9E8NYzWKVZvdVtaUgWvsdshFKA</span><span>"</span><span>,
    </span><span>"</span><span>expires_in</span><span>"</span>:<span>7200</span><span>
}</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>Wm3WZYTPz0wzccnW
jsapi_ticket</span>=sM4AOVdWfPE4DxkXGEs8VMCPGGVi4C3VM0P37wVUCFvkVAy_90u5h9nbSlYy3-Sl-<span>HhTdfl2fzFy1AOcHKP7qg
timestamp</span>=<span>1414587457</span><span>
url</span>=http:<span>//</span><span>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>1414587457</span>&url=http:<span>//</span><span>mp.weixin.qq.com?params=value</span>

步骤2. 对string1进行sha1签名，得到signature：

0f9de62fce790f9a083d5c99e95740ceb90c27ed

}</span>

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>php
</span><span>require_once</span> "jssdk.php"<span>;
</span><span>$jssdk</span> = <span>new</span> JSSDK("yourAppID", "yourAppSecret"<span>);
</span><span>$signPackage</span> = <span>$jssdk</span>-><span>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><</span><span>script </span><span>src</span><span>="http://res.wx.qq.com/open/js/jweixin-1.1.0.js"</span><span>></</span><span>script</span><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>
          wx.config({
            debug: </span><span>false</span><span>,
            appId: </span>'<?php echo $signPackage["appId"];?>'<span>,
            timestamp: </span><?php echo $signPackage["timestamp"];?><span>,
            nonceStr: </span>'<?php echo $signPackage["nonceStr"];?>'<span>,
            signature: </span>'<?php echo $signPackage["signature"];?>'<span>,
            jsApiList: [
              </span><span>//</span><span> 所有要调用的 API 都要加到这个列表中</span>
                'checkJsApi'<span>,
                </span>'openAddress'<span>,
              ]
          });
        </span></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>function</span><span> () {
});</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> wx.checkJsApi({
                jsApiList: [
                    </span>'openAddress'<span>,
                ],
                success: </span><span>function</span><span> (res) {
                    alert(JSON.stringify(res));
                }
            });</span>

5.3. 实现收货地址共享

<span>            wx.openAddress({
              trigger: </span><span>function</span><span> (res) {
                alert(</span>'用户开始拉出地址'<span>);
              },
              success: </span><span>function</span><span> (res) {
                alert(</span>'用户成功拉出地址'<span>);
                alert(JSON.stringify(res));
                document.form1.address1.value         </span>=<span> res.provinceName;
                document.form1.address2.value         </span>=<span> res.cityName;
                document.form1.address3.value         </span>=<span> res.countryName;
                document.form1.detail.value           </span>=<span> res.detailInfo;
                document.form1.national.value         </span>=<span> res.nationalCode;
                document.form1.user.value            </span>=<span> res.userName;
                document.form1.phone.value            </span>=<span> res.telNumber;
                document.form1.postcode.value         </span>=<span> res.postalCode;
                document.form1.errmsg.value         </span>=<span> res.errMsg;
                document.form1.qq.value             </span>= 1354386063<span>;
              },
              cancel: </span><span>function</span><span> (res) {
                alert(</span>'用户取消拉出地址'<span>);
              },
              fail: </span><span>function</span><span> (res) {
                alert(JSON.stringify(res));
              }
            });</span>
