Question

我正在尝试实现一个读取zip文件的休息服务。客户端调用此服务，并从响应中构建zip文件。我有这个用于我的服务：

@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;
}

如果这是正确的方法，有人可以告诉我吗？

尝试这样的方法，从响应的InputStream读取并写入FileOutputstream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();

Rest Service在客户端读取zip文件
