php 支付宝 SDK 单笔转账

支付宝单笔转账,记录下使用过程和一些碰到的问题,以便为同样需求的提供一些参考.

官方的一些文档:单笔转账 , SDK,如何生成及配置公钥证书(视频),公钥证书

上面差不多是准备的工作,配置好后把三个证书都下载下来,这里可能有一些用错文件的情况

下载后的文件名称

SDK里面已经写了一个例子,这里贴出来

这里需要注意两个地方
使用证书模式本地必须开始SSL
如果出现SSL certificate: unable to get local issuer certificate错误信息
解决办法：到 curl.haxx.se/ca/cacert.pem 下载pem文件，并将文件拷贝到如下路径(根据自己的实际情况),并在php.ini 增加
curl.cainfo =”E:/wamp64/bin/php/php7.0.10/extras/ssl/cacert.pem”

另外一个就是这个SDK 的alipaySDK中定义的Encrypt()/Decrypt()函数与Laravel中定义的Encrypt()/Decrypt()函数重名了。这里在文件中查找encrypt/decrypt替换为alipayEncrypt/alipayDecrypt即可。
