关于在线支付的（Pay Pal Pro）

Question

由于现在公司在做一个国外的项目
在线支付现在在做的是 Pay pal pro 的接口方式
用到了2种：
Direct Payment 和  Express Checkout
但是要是短短三天内看完文档并集成到系统中
我感觉还是有点紧
所以希望有做过的高人能够在这里提供点经验或是一些相关的代码
最好是自己在实际中用到的
或是用过的朋友遇到的问题以及解决方法
希望都能够贴在这里
这样我就可以少走弯路了
希望大家不要吝啬自己的经验！！
^_^

Answer 2

不用看太多文档
注册paypal账户
在控制面板去“商家工具”
里面有详细说明

Answer 3

难确实不难
只是三天的时间就用进去
担心有什么纰漏
毕竟这个和 dollar 扯上关系了
也会和我的 money 扯上关系
所以不敢随便

Answer 4

刚在这里：https://www.sandbox.paypal.com/玩了半天
在里面可以建立测试账户买家和卖家
在程序中：
//using com.paypal.sdk.core.nvp;
//using com.paypal.sdk.core;
//using com.paypal.sdk.profiles;
//using com.paypal.sdk.util;
//using com.paypal.sdk.services;
       //验证卖家信息，申请后激活开通就有这个了
       IAPIProfile profile = ProfileFactory.createSignatureAPIProfile();
        profile.APIUsername = "sdk-three_api1.sdk.com";
        profile.APIPassword = "QFZCWN5HZM8VBG7Q";
        profile.APISignature = "A21eW1ch..NEqJJ-glaLhqkBMlzeAsWqX0ycck-CTc0tKI4pa1u.rgNF";
        profile.Environment = "sandbox";
        // SSL 证书，还不会玩，只用上面的简单验证（签名方式）
        //profile.CertificateFile = "sdk-seller.p12";      
        //profile.PrivateKeyPassword = "password"; 
        TestConnection test = new TestConnection();
        string result = test.testServerConnection(profile);
        //测试链接，如果正常，应该是返回 successful
        Response.Write("<hr/>"+result+"<hr/>");
NVPCallerServices caller = new NVPCallerServices();
        caller.APIProfile = profile;
        NVPCodec encoder = new NVPCodec();
        encoder["METHOD"] = "DoDirectPayment";
        encoder["PAYMENTACTION"] = "Authorization"; //or "Sale"
        encoder["AMT"] = "99.99";
        encoder["CREDITCARDTYPE"] = "Visa";
        encoder["ACCT"] = "4595258908900506";
        encoder["EXPDATE"] = "082018";
        encoder["CVV2"] = "962";
        encoder["FIRSTNAME"] = "John";
        encoder["LASTNAME"] = "Doe";
        encoder["STREET"] = "123 Fake St";
        encoder["CITY"] = "Omaha";
        encoder["STATE"] = "NE";
        encoder["ZIP"] = "68104";
        encoder["COUNTRYCODE"] = "US";
        encoder["CURRENCYCODE"] = "USD";        string pStrrequestforNvp = encoder.Encode();
        string pStresponsenvp = caller.Call(pStrrequestforNvp);        NVPCodec decoder = new NVPCodec();
        decoder.Decode(pStresponsenvp);        string strAck = decoder["ACK"];
        if (strAck != null && (strAck == "Success" || strAck == "SuccessWithWarning"))
        {
            string pStrResQue = "TRANSACTIONID=" + decoder["TRANSACTIONID"] + "<br>" +
                "AMT=" + decoder["AMT"] + "<br>" +
                "AVSCODE=" + decoder["AVSCODE"] + "<br>" +
                "CVV2MATCH=" + decoder["CVV2MATCH"];
            Response.Write(pStrResQue);
         }
        else
        {
            string pStrError = "ErrorCode=" + decoder["L_ERRORCODE0"] + "<br>" +
                "Desc=" + decoder["L_SHORTMESSAGE0"] + "<br>" +
                "Desc2=" + decoder["L_LONGMESSAGE0"];
            Response.Write(pStrError);
         }至此 DoDirectPayment  基本算是能够用了，不过 
string pStresponsenvp = caller.Call(pStrrequestforNvp) 这个地方要等很长时间，看来还是得用 ajax 做一下，页面放个 waiting for proecessing...
贴出来希望做过这个的给个意见
接下来研究 Express Checkout 
也希望大家能够帮一下！

自己去注册个沙箱做测试。web服务引用是

一小部分代码，里面有很多我自己写的公共层中的类，不能全部解释。希望对楼主有帮助。

谢谢楼上的
    希望能够给一些地址验证，支付金额验证的思路或是代码
再就是客户付款，我在后台该如何去取款？如果是 order，怎么去发货？
