二、开发前准备工作
1、签约：[url]https://openclub.alipay.com/read.php?tid=276&fid=72[/url]
2、创建应用：[url]https://openclub.alipay.com/read.php?tid=1606&fid=72[/url]
3、生成密钥：[url]https://openclub.alipay.com/read.php?tid=1833&fid=69[/url]
4、下载服务端sdk：

检查调用appid的应用功能列表中是否添加“电脑网站支付”并显示已签约。
三、接口集成示例代码
1、参数说明
（1）out_trade_no：商户订单号，由商户自定义设置；
（2）subject：商品标题；
（3）product_code：固定产品码值：FAST_INSTANT_TRADE_PAY；
（4）total_amount：交易订单金额，精确到小数点后2位，最小设置为0.01；
2、JAVA版请求示例
（适用于jdk1.5以上）
//获得初始化的AlipayClient
AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.gatewayUrl, AlipayConfig.app_id, AlipayConfig.merchant_private_key, "json", AlipayConfig.charset, AlipayConfig.alipay_public_key, AlipayConfig.sign_type);
//设置请求参数
AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
//同步通知地址：支付成功后页面自动跳转到传值地址中
alipayRequest.setReturnUrl("https://docs.open.alipay.com/200");
//异步通知地址：支付成功生成之后会post返回订单信息详情到该地址，用于商家做业务逻辑处理
alipayRequest.setNotifyUrl("https://docs.open.alipay.com/200");
AlipayTradePagePayModel model = new AlipayTradePagePayModel();
model.setSubject("电脑网站支付测试");
model.setTotalAmount("0.01");
model.setProductCode("FAST_INSTANT_TRADE_PAY");
//自定义参数请转码后传入该参数内，可以传值逗号，等号之类，但不能传引号，否则会报错，其他特殊符号是否报错以实测为准
String passback_params = "{ab=测试一下;tdst=公共参数;ccsd=gds；dfa=23·12}";
String passback_params2 =URLEncoder.encode(passback_params,"UTF-8");
model.setPassbackParams(passback_params2);
alipayRequest.setBizModel(model);
/**
* BizContent传值模式
alipayRequest.setBizContent("{\"out_trade_no\":\"20150320010101001\","
+ "\"total_amount\":\"88.88\","
+ "\"subject\":\"subject\","
+ "\"qr_pay_mode\":\"4\","
+ "\"timeout_express\":\"1m\","
+ "\"passback_params2\":\"passback_params2\","
+ "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
**/
//get请求方式，返回http链接
AlipayTradePagePayResponse respose = alipayClient.pageExecute(alipayRequest,"get");
//post请求方式，返回from表单
//AlipayTradePagePayResponse respose = alipayClient.pageExecute(alipayRequest);
//打印请求信息
System.out.println(respose.getBody()); 3、PHP版请求示例
（适用于ph5.5以上环境）
<?php
require_once 'AopSdk.php';
$aop = new AopClient ();
$aop->appId = '填写您的appid';
$aop->rsaPrivateKey = '填写您的私钥';
$aop->alipayrsaPublicKey='填写您的支付宝公钥';
$aop->gatewayUrl = 'https://openapi.alipay.com/gateway.do';
$aop->apiVersion = '1.0';
$aop->postCharset='utf-8';
$aop->format='json';
$aop->signType = 'RSA2';
//生成随机订单号
$date=date("YmdHis");
$arr=range(1000,9999);
shuffle($arr);
$request = new AlipayTradePagePayRequest();
//收款方账户类型为：ALIPAY_LOGONID：支付宝登录号，支持邮箱和手机号格式。
$request->setBizContent("{" .
""out_trade_no":"".$date.$arr[0].""," .
""total_amount":"0.1"," .
""subject":"电脑网站支付测试"," .
""product_code":"FAST_INSTANT_TRADE_PAY"" .
"}");
//get请求,返回链接
$result = $aop->pageExecute($request,"get");
//post请求，返回表单
//$result = $aop->pageExecute($request);
print_r(htmlspecialchars($result));
?> 4、.NET版请求示例
注：适用于Visual studio 2010及以上版本、Framework3.5 SP1及以上版本的开发环境
沙箱测试代码示例：
using Aop.Api;
using Aop.Api.Request;
using Aop.Api.Response;
using System;
using System.IO;
/**
* 沙箱电脑网站支付
* 文档地址：[url]https://docs.open.alipay.com/270/alipay.trade.page.pay[/url]
* */
namespace AlipayTradePagePay
{
class Program
{
//沙箱支付宝公钥，查看地址：[url]https://openhome.alipay.com/platform/appDaily.htm[/url]
public static string alipay_public_key = @"支付宝公钥";
//沙箱pkcs1私钥，千万不要用pkcs8格式的 ,如何获取，请查看：[url]https://openclub.alipay.com/read.php?tid=1833&fid=25[/url]
public static string merchant_private_key = @"私钥";
static void Main(string[] args)
{
//初始化
IAopClient alipayClient = new DefaultAopClient("https://openapi.alipaydev.com/gateway.do", "appid", merchant_private_key, "json", "1.0", "RSA2", alipay_public_key, "utf-8", false);
AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
//请求参数设置
request.BizContent = "{"out_trade_no":"201810201450FDSa","subject":"沙箱测试","product_code":"FAST_INSTANT_TRADE_PAY","total_amount":"0.01"}";
//同步跳转地址，用于订单支付成功之后同步跳转
request.SetReturnUrl("https://docs.open.alipay.com/200");
//异步跳转地址，用于接收异步返回结果
request.SetNotifyUrl("https://docs.open.alipay.com/200");
//默认是post请求方式，返回form表单
AlipayTradePagePayResponse response = alipayClient.pageExecute(request);
//get请求方式，返回请求链接
//AlipayTradePagePayResponse response = client.pageExecute(alipayRequest, "", "GET");
//打印返回结果
Console.WriteLine(response.Body);
}
// 私钥文件类型转换成纯文本类型 返回过滤后的字符串类型私钥
public static string getMerchantPriveteKeyStr()
{
StreamReader sr = new StreamReader(merchant_private_key);
string pubkey = sr.ReadToEnd();
sr.Close();
if (pubkey != null)
{
pubkey = pubkey.Replace("-----BEGIN PUBLIC KEY-----", "");
pubkey = pubkey.Replace("-----END PUBLIC KEY-----", "");
pubkey = pubkey.Replace("r", "");
pubkey = pubkey.Replace("n", "");
}
return pubkey;
}
}
} post请求返回结果：
