全国快递物流查询接口如何用C#进行调用

一、引言

在电子商务和物流行业快速发展的今天，提供即时的快递物流信息对于提升客户满意度至关重要。通过全国快递物流查询接口，您可以轻松获取包裹的实时状态更新。本文将指导您如何使用C#语言来调用这类接口，并给出一个简单的示例代码，帮助开发者快速上手。

二、如何用C#进行调用？

下面我们来以探数API在阿里云的接口代码为例

接口地址：https://market.aliyun.com/detail/cmapi00065859
//using System.IO;
//using System.Text;
//using System.Net;
//using System.Net.Security;
//using System.Security.Cryptography.X509Certificates;

private const String host = "https://tsexpress.market.alicloudapi.com";
private const String path = "/exp/index";
private const String method = "GET";
private const String appcode = "你自己的AppCode";

static void Main(string[] args)
{
String querys = "no=78792812069699&phone=phone&com=com";
String bodys = "";
String url = host + path;
HttpWebRequest httpRequest = null;
HttpWebResponse httpResponse = null;

if (0 < querys.Length)
{
url = url + "?" + querys;
}

if (host.Contains("https://"))
{
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);
httpRequest = (HttpWebRequest)WebRequest.CreateDefault(new Uri(url));
}
else
{
httpRequest = (HttpWebRequest)WebRequest.Create(url);
}
httpRequest.Method = method;
httpRequest.Headers.Add("Authorization", "APPCODE " + appcode);
if (0 < bodys.Length)
{
byte[] data = Encoding.UTF8.GetBytes(bodys);
using (Stream stream = httpRequest.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
}
try
{
httpResponse = (HttpWebResponse)httpRequest.GetResponse();
}
catch (WebException ex)
{
httpResponse = (HttpWebResponse)ex.Response;
}

Console.WriteLine(httpResponse.StatusCode);
Console.WriteLine(httpResponse.Method);
Console.WriteLine(httpResponse.Headers);
Stream st = httpResponse.GetResponseStream();
StreamReader reader = new StreamReader(st, Encoding.GetEncoding("utf-8"));
Console.WriteLine(reader.ReadToEnd());
Console.WriteLine("\\n");

}

public static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
return true;
}
