微信支付第三方sdk使用

1、引入依赖：（对于依赖冲突自行解决）

微信支付第三方sdk使用的相关文章

微信支付PHP SDK —— 公众号支付代码详解

在微信支付 开发者文档页面 下载最新的 php SDK http://mch.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1 这里假设你已经申请完微信支付 1. 微信后台配置  如图 我们先进行测试,所以先把测试授权目录和 测试白名单添加上.测试授权目录是你要发起微信请求的哪个文件所在的目录. 例如jsapi 发起请求一般是jsapi.php所在目录 为测试目录,测试白名单即开发人员的微信号. 正式的支付授权目录不能和测试的一样否则会报错.不填

微信支付官方SDK V3 .NET版的坑

我觉得玩微信支付最大的难点和瓶颈并不是微信支付本身,而是能够拿到微信支付的权限.首先微信支付所面向的开发对象不是个人,所以个人开发者不会有这样的权限,另外一方面公司的微信号又不会随便给个人进行开发,这样就陷入了一个比较尴尬的循环! 在好不容易搞到权限后,发现官方的sdk里面竟然有.NET版本,这让小猪欣喜如狂,赶紧下下来研究一番.这也就有了本文. 在设置好开发环境,测试白名单,,回调…确定微信后台设置已经没有问题之后. 接下来看.NET版本中的坑 默认Default.aspx中的链接竟然都是链接

PHP 微信支付-借助SDK

记一次自己亲自走通微信支付流程的过程: 首先拿到需要的公众号Appid.AppSecret.商户id.支付秘钥然后到微信支付的开发文档中下载 需要的SDK版本,第一次是全部使用SDK只是放到服务器上走了一遍.然后自己动手写了一遍 前端页面: <?php header("Content-type:text/html;charset=utf-8"); include './lib/WxPay.Api.php'; include './wxConfig.php'; include '.

Android应用之——微信微博第三方sdk登录分享使用过程中的一些常见问题

前言 近期在使用第三方登录和分享的过程中遇到了非常多问题,一方面能够归结为自己经验的不足,还有一方面事实上也说明了官方文档的含糊不清.这篇博文不会写关于怎样使用第三方登录分享,由于官方文档已经写明了步骤,这里要写的东西是官方文档里面没用说明的一些问题,也是我自己在摸索的过程中发现和解决的问题. 一.微博登录和分享 微博sdk的集成过程官方下载的sdk文档中已经基本说明清楚了.这里不提了,说两个常常遇到过问题. 1.登录后停留在授权页,也就是登录后没有返回我们的应用.排除代码方面的原因后.还有几个

第三方支付之微信支付(扫码支付)

第一步:注册微信支付账户,开通扫码支付 具体流程请参照官方说明 第二步:创建Maven项目 1. 添加微信支付SDK依赖.二维码工具依赖(微信支付需要自己通过二维码工具生成支付二维码) <!-- 微信支付 --> <dependency> <groupId>com.github.wxpay</groupId> <artifactId>wxpay-sdk</artifactId> <version>0.0.3</ver

IOS更换64位支付宝 微信支付 SDK

14年的时候苹果就下发通知:新的上线项目必须适配64-bit,更新的项目在2015年的六月一号以后也必须适配64-bit刚开始的时候没注意到这个问题,当打包完自己项目的时候,居然在适配64-bit的时候出现了一个警告, 看了一下,大概的意思也就是说,我的项目没有适配64-bit,我勒个去,上个版本还没有提示这个,这个版本居然冒出这个警告了.眼看着六月一号也即将到来,十天时间,以苹果的审核进度不一定过的了,万一中间再出个小插曲,估计上线得一个月了,加速审核苹果不一定买帐.迟早要做64bit的适配的

iOS SDK微信支付填坑！（跳转微信支付，只有确定按钮）

这两天接微信支付的SDK,遇到了一个天坑,微信文档里面不写清楚,demo里面也没有,参数少了一个无法支付啊有没有!有没有!有没有! 最后调试成功,得知真相的我眼泪掉下来... 先让我们看看是什么情况: --------------------------------------------------------我是分割线-------------------------------------------------------- 预支付订单那块就不说了,基本上都没问题,服务器会返回一个pre

iOS-关于微信支付

突然发现的一篇文章,这位博主介绍的还是挺详细的,给大家分享一下 不懂的也可以咨询我qq:564702640 1.申请接入 详见 微信支付申请接入 . 创建应用+审核通过,你将得到:APP_ID.APP_SECRET.APP_KEY.PARTNER_ID .那就可以开始实现支付功能的接入. 2.业务流程 不管是客户端还是后台开发者,微信支付开发者文档里面这张交互时序图,都有必要看看.其实很多开发者,当然也包括我,在接入第三方sdk时,一般都是从其官方demo入手,快速了解其api.结果在这里就掉坑
