支付宝SDK使用说明

支付宝SDK说明

<code>$c = new AopClient;
$c->gatewayUrl = "https://openapi.alipay.com/gateway.do";
$c->appId = "app_id";
$c->privateKey = "your private_key";
$c->format = "json";
$c->charset= "GBK";
$c->alipayPulicKey = "alipay_public_key";
//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
$req = 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->bizContent = "{
    "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"
  }"
$response= $c->execute($req);</code>

但是总是返回 缺少签名参数,有没有详细的接口说明？
