好的,以下是一个完整的 C# 示例代码,演示如何使用 HttpClient 类从 ABAP 服务器获取 Gzip 压缩数据,并使用 GZipStream 类解压缩数据:
```
using System;
using System.IO;
using System.IO.Compression;
using System.Net.Http;
using System.Threading.Tasks;
class Program
{
static async Task Main(string[] args)
{
// Create a new HttpClient instance
HttpClient client = new HttpClient();
// Set the Accept-Encoding header to indicate that we can handle gzip-compressed responses
client.DefaultRequestHeaders.AcceptEncoding.Add(new System.Net.Http.Headers.StringWithQualityHeaderValue("gzip"));
// Set the request URI to the ABAP service endpoint
string uri = "http://localhost:8000/sap/opu/odata/sap/ZTEST_SRV/Products?$format=json";
// Send the request and get the response as a byte array
byte[] responseBytes = await client.GetByteArrayAsync(uri);
// Create a MemoryStream from the response byte array
using (MemoryStream compressedStream = new MemoryStream(responseBytes))
{
// Create a GZipStream to decompress the data
using (GZipStream gzipStream = new GZipStream(compressedStream, CompressionMode.Decompress))
{
// Create a MemoryStream to store the uncompressed data
using (MemoryStream uncompressedStream = new MemoryStream())
{
// Copy the uncompressed data from the GZipStream to the MemoryStream
gzipStream.CopyTo(uncompressedStream);
// Convert the uncompressed MemoryStream to a string and print it
string uncompressedString = System.Text.Encoding.UTF8.GetString(uncompressedStream.ToArray());
Console.WriteLine(uncompressedString);
}
}
}
}
}
```
在上面的示例中,我们使用 HttpClient 类发送一个 GET 请求到 ABAP 服务器,并指定 Accept-Encoding 头以请求 Gzip 压缩数据。然后,我们将响应作为字节数组获取,并使用 GZipStream 类解压缩数据。最后,我们将解压缩的数据转换为字符串并输出到控制台。
希望这个完整的示例代码可以帮助您理解如何在 C# 中解析 ABAP 返回的 Gzip 数据。
