一,微信H5支付只能用在手机浏览器中,比如百度浏览器,UC浏览器等,不可以用在微信中,微信中只可以使用公众号支付.要特别注意.
二,如果你的h5手机版网站加壳打包封装成了APP,根据我们的测试,也可以使用微信h5支付.不过.据微信官方说,可能会提示商家参数格式有误，请联系商家解决,原因. 当前调起H5支付的referer为空导致，一般是因为直接访问页面调起H5支付，请按正常流程进行页面跳转后发起支付，或自行抓包确认referer值是否为空如果是在封装的APP里调起H5支付，需要在webview中手动设referer，如(Map extraHeaders = new HashMap();ex
traHeaders.put(“Referer”, “商户申请H5时提交的授权域名”);//例如 http://www.baidu.com ))
以上是,微信官方的说明,如果你的网站需要打包成APP.可以具体咨询对方技术人员,打包后,是否影响h5支付.以免纠纷.
三,微信支付最麻烦的就是签名失败.很多时候与网站中的中文编码有关,注意转码.
四,支付文件需放到支付授权目录下，可以在微信支付商户平台->产品中心->开发配置中设置。
代码如下,本文的所有代码默认放在muserwxpay目录中,
一.wxpay目录中的H5.config.php 配置文件,这个文件一般是后台保存后.自动生成的文件.内容为
代码语言：javascript复制<? return array( 'APPID' => 'wxc35486954cde','MCHID' => '1496515882','KEY' => '6ac2b9e536763299','APPSECRET' => '6ac2b9e53676328c46e','SSLCERT_PATH' => '','SSLKEY_PATH' => '',' CURL_PROXY_HOST' => '','CURL_PROXY_PORT' => 0,'REPORT_LEVENL' => 1);?>三,h5_pay.php 支付文件.本文件中,需要生成订单并保存到你的数据库中,并跳转到微信,进行支付.
代码语言：javascript复制<?php
