如何使用REST API和.Net下载LiveLink (OpenText)文件(C# /VB)

using System;
using System.IO;
using System.Net.Http;

class Program
{
    static async void DownloadFile()
    {
        string apiUrl = "https://example.com/api/download"; // 替换为LiveLink (OpenText)的文件下载接口URL
        string apiKey = "YOUR_API_KEY"; // 替换为你的API密钥或访问令牌

        HttpClient client = new HttpClient();
        client.DefaultRequestHeaders.Add("Authorization", "Bearer " + apiKey);

        HttpResponseMessage response = await client.GetAsync(apiUrl);
        if (response.IsSuccessStatusCode)
        {
            using (Stream contentStream = await response.Content.ReadAsStreamAsync())
            {
                using (FileStream fileStream = File.Create("path/to/save/file"))
                {
                    await contentStream.CopyToAsync(fileStream);
                }
            }
        }
        else
        {
            Console.WriteLine("Failed to download file. Status code: " + response.StatusCode);
        }
    }

    static void Main(string[] args)
    {
        DownloadFile();
    }
}
