本人最近做了微信支付开发,是第一次接触.其中走了很多弯路,遇到的问题也很多.为了让和我一样的新人不再遇到类似的问题,我把我的开发步骤和问题写出来,以供参考.
开发时间是2016/8/2,所以微信支付的版本也是对应此时的版本.
一.前期准备：
首先你们公司开通微信支付功能后，会收到一份邮件，里面有账户相关信息，一般有：微信支付商户号，商户平台登录帐号，商户平台登录密码，申请对应的公众号，公众号APPID。
1.下载demo：用上面信息登陆“微信商户平台”，>>>（右上角开发文档）>>>公众号支付>>>sdk下载>>>选php
2.下载证书：账户中心>>>api安全

3.配置好后去微信公众平台,里面有微信支付功能如下图.在开发配置中设置支付目录和测试目录.这里主要是配置测试目录,支付目录可以先不管(我的域名是www.test.com),然后将自己的微信号加入测试白名单.
4.再去微信公众平台>>>开发>>>接口权限>>>网页服务的第一项`网页账号`,修改它的值为你自己的域名(仅仅是域名).如图:
二.demo代码修改(仅仅针对当前的版本):
1. 修改文件WxPay.Api.php
将curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,TRUE);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,2);//严格校验
改为:
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,FALSE);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,FALSE);//严格校验2

三.开始开发,按大概流程讲述:
1.支付:首先点击支付后,会到jsapi.php文件中去,获取openid,这步我没管,也没出错;
然后是统一下单,他会设置一大堆参数,如图:
将里面的setNotify_url设置为你的notify.php文件所在的位置.
其中的setOut_trade_no和setTotal_fee这两个参数是你可以随便填写的(其他参数默认可以).在支付成功后微信服务器会将这两个参数的值返回给你.我是直接将商品订单号码放到setOut_trade_no中传递过去.在这一步,我遇到的问题是,get过来的字符串参数总是放不到setOut_trade_no中,最后我发现传过来的订单字符串被莫名奇妙的加上了单引号.于是我接收到字符串后先用trim函数处理,然后就能放入了.
此时点击支付,应该可以去支付了.(支付的结果在商户平台中查看)
