Question

我是nodejs的新手，所以这可能是操作员错误，但我试图向PayPay的测试网址发出POST请求。我尝试在nodejs中使用http请求，但得到了一个奇怪的响应。我能够让命令行上的curl工作，所以我想我在节点中使用curl。

当我在bash中运行以下curl命令时，它可以工作：

curl -v --data "USER=myLogin&VENDOR=myLogin&PARTNER=PayPal&PWD=QQQQQQQQQ&CREATESECURETOKEN=Y&SECURETOKENID=fb7810e9-252b-4613-a53b-6432148bfd97&TRXTYPE=S&AMT=100.00" https://pilot-payflowpro.paypal.com

我得到以下结果（我知道使用了安全令牌，但它是卷曲调用的标志）：

* Rebuilt URL to: https://pilot-payflowpro.paypal.com/
*   Trying 173.0.82.163...
* Connected to pilot-payflowpro.paypal.com (173.0.82.163) port 443 (#0)

然后我使用以下nodejs代码（在通过Express公开的方法中作为GET）：

var newSId = uuid.v4();
var curl = new Curl();
var url = 'https://pilot-payflowpro.payapl.com/';
var data = {
  'USER': 'myLogin',
  'VENDOR': 'myLogin',
  'PARTNER': 'PayPal',
  'PWD': 'QQQQQQQQQQQ',
  'CREATESECURETOKEN': 'Y',
  'SECURETOKENID': newSId,
  'TRXTYPE': 'S',
  'AMT': '100.00'
};

data = qstr.stringify(data);

console.log("Data = " + data);

curl.setOpt(Curl.option.URL, url);
curl.setOpt(Curl.option.POSTFIELDS, data);
curl.setOpt(Curl.option.POST, 1);
curl.setOpt(Curl.option.VERBOSE, true);

curl.perform();

curl.on('end', function(statusCode, body){
   this.close();
});

curl.on('error', curl.close.bind(curl));

当我通过浏览器执行GET时，我将以下信息转储到控制台：

Data = USER=myLogin&VENDOR=myLogin&PARTNER=PayPal&PWD=QQQQQQQQ&CREATESECURETOKEN=Y&SECURETOKENID=4b8f0763-2d09-4c2a-a57e-f5a4dc5be744&TRXTYPE=S&AMT=100.00
*   Trying 209.15.13.134...
* connect to 209.15.13.134 port 443 failed: Connection refused
* Failed to connect to pilot-payflowpro.payapl.com port 443: Connection refused
* Closing connection 0

出于某种原因，我无法解释，在node-libcurl调用中，正在使用不同的IP地址。 curl命令行调用使用：173.0.82.163，但node-libcurl使用：209.15.13.134。我很好奇为什么。如果有一种方法我应该更好地调试，请告诉我。

提前致谢！

看来至少URL中的域名有拼写错误，应该是paypal.com而不是payapl.com（这是一个骗局/垃圾网站）。

node-libcurl在POST上获取错误的IP地址
