Rest服務讀取客戶端中的zip文件

Question

我想實現讀取zip文件的rest服務。客戶調用此服務，並從響應中生成zip文件。我有這個爲我的服務：

@Produces({ "application/zip" }) 
@GET 
@Path("/fetchZip") 
public Response getZip() { 
try { 
    InputStream theFile = new FileInputStream("test.zip"); 
    ZipInputStream zis = new ZipInputStream(theFile); 
    return Response.ok(zis).build(); 
} catch (Exception e) { 
    e.printStackTrace(); 
} 
return null; 
} 

任何人都可以讓我知道，如果這是正確的方式做到這一點？

嘗試這樣的事情，從響應的InputStream進行讀取和寫入FileOutputstream的文件：

 URL url = new URL("YOUR_URL"); 
    HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
    conn.setDoOutput(true); 
    conn.setRequestMethod("GET"); 
    conn.setRequestProperty("Content-Type", "application/json"); 
    if (conn.getResponseCode() == 200) { 
     InputStream inputStream = conn.getInputStream(); 
     OutputStream output = new FileOutputStream("C:/yourFile.zip"); 
     byte[] buffer = new byte[1024]; 
     int bytesRead; 
     while ((bytesRead = inputStream.read(buffer)) != -1) { 
      output.write(buffer, 0, bytesRead); 
     } 
     output.close(); 
    } 
    conn.disconnect();
