我不确定如何继续，因为文档似乎没有太大帮助

更新：
我正在尝试使用 HTTPClient，但我不确定我是否正在这样做
protected void btn_Click(object sender, EventArgs e)
using (var client = new HttpClient())
TelrObj obj = new TelrObj();
obj.ivp_method = "create";
obj.ivp_store = 12345;
obj.ivp_cart = "cardid1234";
obj.ivp_test = 1;
obj.return_auth = "xxxx-xxxx-xxx";
obj.return_can = "";
obj.return_decl = "";
obj.ivp_amount = 10;
obj.bill_fname = "David";
obj.ivp_currency = "USD";
var str = " 'method':'create', 'order': 'ref':'OrderRef', 'cartid':'cardid1234', 'test':1,'amount':10,'currency':'USD', 'url':'https://secure.telr.com/gateway/process.html?o=OrderRef' ";
var response = client.PostAsync("https://secure.telr.com/gateway/order.json",
new StringContent(JsonConvert.SerializeObject(str).ToString(),
Encoding.UTF8, "application/json"))
.Result;
Response.Write(response);
if (response.IsSuccessStatusCode)
dynamic content = JsonConvert.DeserializeObject(
response.Content.ReadAsStringAsync()
.Result);
// Access variables from the returned JSON object
var appHref = content.links.applications.href;
回复
StatusCode: 417, ReasonPhrase: 'Expectation Failed', Version: 1.1, Content: System.Net.Http.StreamContent, Headers: Connection: close Date: Tue, 17 Jan 2017 10:52:30 GMT Server: Apache Content-Length: 364 Content-Type: text/html; charset=iso-8859-1
我已更改 return_auth 和 ivp_store，因为我无法分享。任何正确操作的指针都会有很大帮助。
我对那里的文档感到困惑，所以要以正确的方式去做。他们的网站上似乎没有任何 .net 示例，而是有我不理解的 PHP 插件。
我找到了另一个使用 PHP 的 wooCommerce 插件示例

【问题讨论】：
示例展示了一个使用 cURL 的简单 HTTP 请求，你不知道的到底是什么？ @komo 这是文档中显示的示例，但我需要在基于 asp.net webform 的网站中进行相同的工作。我正在尝试使用 HTTPClient 执行此操作，但我总是收到错误 417。 @komo，我更新了问题 基本上你没有正确地阅读文档并试图在没有正确理解文档的情况下跳入代码。它的逻辑会帮助你而不是技术。 JsonConvert.SerializeObject(str) 应该是 JsonConvert.SerializeObject(obj)，它将序列化对象并为 order.json API 创建所需的 JSON。您在“str”中拥有的值是您将从 API 获得的值。 【参考方案1】：如果我使用 Postman 并向 https://secure.telr.com/gateway/order.json 发送以下请求，我将收到 HTTP 200：
POST /gateway/order.json HTTP/1.1
Host: secure.telr.com
Content-Type: application/x-www-form-urlencoded
Cache-Control: no-cache
Postman-Token: 570a44c1-9c4e-58b2-5d4d-fdd352272235
ivp_method=create&ivp_store=12345&ivp_authkey=12345&ivp_cart=12345&ivp_test=1&ivp_amount=100.00&ivp_currency=AED&ivp_desc=Description&return_auth=https%3A%2F%2Fdomain.com%2Freturn.html&return_can=https%3A%2F%2Fdomain.com%2Freturn.html&return_decl=https%3A%2F%2Fdomain.com%2Freturn.html
所以我猜你是以错误的方式构建你的请求（尤其是Content-Type，应该是application/x-www-form-urlencoded，而不是application/json）。
由于我没有ivp_store参数，我无法对其进行更多测试，因此出现以下响应：
"method": "create",
"trace": "4001/18544/587dfa99",
"error":
"message": "E04:Invalid store ID"
编辑：
以下是工作示例：
static void Main(string[] args)
using (var client = new HttpClient())
client.BaseAddress = new Uri("https://secure.telr.com/");
client.DefaultRequestHeaders.ExpectContinue = false;
var result = client.PostAsync("gateway/order.json",
new FormUrlEncodedContent(new List<KeyValuePair<string, string>>()
new KeyValuePair<string, string>("ivp_method", "create"),
new KeyValuePair<string, string>("ivp_store", "12345"),
new KeyValuePair<string, string>("ivp_authkey", "12345"),
new KeyValuePair<string, string>("ivp_cart", "12345"),
new KeyValuePair<string, string>("ivp_desc", "Desc"),
new KeyValuePair<string, string>("ivp_test", "1"),
new KeyValuePair<string, string>("ivp_amount", "100.00"),
new KeyValuePair<string, string>("ivp_currency", "AED"),
new KeyValuePair<string, string>("return_auth", "https://wwww.google.pl"),
new KeyValuePair<string, string>("return_can", "https://wwww.google.pl"),
new KeyValuePair<string, string>("return_decl", "https://wwww.google.pl"),
)).Result;
Console.WriteLine(result.Content.ReadAsStringAsync().Result);
Console.ReadLine();
注意以下行：
client.DefaultRequestHeaders.ExpectContinue = false;
这是此服务器所必需的。如果您不包含此行并运行我的代码，您将得到以下响应：
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>417 Expectation Failed</title>
</head><body>
<h1>Expectation Failed</h1>
<p>The expectation given in the Expect request-header
field could not be met by this server.
The client sent<pre>
Expect: 100-continue
</pre>
</p><p>Only the 100-continue expectation is supported.</p>
</body></html>
HttpClient 默认发送 Expect: 100-continue 标头，这显然会与您尝试连接的服务器混淆。
【讨论】：
它只是一个 Chrome 扩展程序。我想我可以使用来自.NET 的HttpClient 得到相同的结果。
能否请您分享一段 C# 代码，以便我也可以测试。我试过邮递员我也无法让它工作我不断收到错误的请求
@Learning - 为您的问题发布了解决方案。
感谢我会尝试它
我当然会，我正面临结果集的问题，因为我必须在 KeyValuePair 中传递多个数据类型，因为我返回的框架显示为空白我确信这是由于我传递的单一数据类型.我正在使用`var response = client.PostAsync("https://secure.telr.com/gateway/order.json", new StringContent(JsonConvert.SerializeObject(obj).ToString(), Encoding.UTF8, "application/json")) .Result;以上是关于在 ASP.NET 中集成支付网关的主要内容，如果未能解决你的问题，请参考以下文章
