php实现单笔转账到支付宝功能

//实例化客户端
AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", APP_ID, APP_PRIVATE_KEY, "json", CHARSET, ALIPAY_PUBLIC_KEY, "RSA2");
//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.open.public.template.message.industry.modify 
AlipayOpenPublicTemplateMessageIndustryModifyRequest request = new AlipayOpenPublicTemplateMessageIndustryModifyRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数
//此次只是参数展示，未进行字符串转义，实际情况下请转义
request.setBizContent(" {" +
" \"primary_industry_name\":\"IT科技/IT软件与服务\"," +
" \"primary_industry_code\":\"10001/20102\"," +
" \"secondary_industry_code\":\"10001/20102\"," +
" \"secondary_industry_name\":\"IT科技/IT软件与服务\"" +
" }");
AlipayOpenPublicTemplateMessageIndustryModifyResponse response = alipayClient.execute(request); 
//调用成功，则处理业务逻辑
if(response.isSuccess()){
 //.....
