如何保存从 HTTP 获取的文件在磁盘文件 java 上获取响应

Question

I am getting a file in response to the HTTP GET request. I tried the following curl command which is providing me the exact output that I want:

curl -X GET <URL> -H 'Authorization: Bearer <token>' --output <Path on local machine>/Test.pdf

Can someone provide a java code to save this file on my local storage without using an external library?

Answer 1

How about trying to write the code and get some practice on java.net and java.io packages?

Please take a look at class URL and method openStream for getting access to content.

You can then save that by leveraging Java File IO, classes of interest would be BufferedInputStream for reading content and BufferedOutputStream for saving content.
