英文:
Is there a way to download a .jar file with a httpurlconnection?
问题
服务器正在发送一个JAR文件，我想将其保存在特定目录中。
我的HttpURLConnection仅在读取文件的内容。
public static String update(String url, String version) throws MalformedURLException, IOException {
HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
return readResponse(con.getInputStream());
}
private static String readResponse(InputStream in){
BufferedReader br = new BufferedReader(new InputStreamReader((in)));
StringBuilder sb = new StringBuilder();
String output;
while ((output = br.readLine()) != null) {
sb.append(output);
}
return sb.toString();
}

The server is sending a jar file and i want to save it in a specific directory.
My HttpURLConnection is only reading the content of the file

return readResponse(con.getInputStream());
}
private static String readResponse(InputStream in){
BufferedReader br = new BufferedReader(new InputStreamReader((in)));
StringBuilder sb = new StringBuilder();
String output;
while ((output = br.readLine()) != null) {
sb.append(output);

为什么将其解析为字符串？
也许尝试一下（https://www.baeldung.com/java-download-file）
InputStream in = new URL(FILE_URL).openStream();
Files.copy(in, Paths.get(FILE_NAME), StandardCopyOption.REPLACE_EXISTING);
英文:
Why are u parsing it as a string?
Maybe try (https://www.baeldung.com/java-download-file)
InputStream in = new URL(FILE_URL).openStream();
Files.copy(in, Paths.get(FILE_NAME), StandardCopyOption.REPLACE_EXISTING);
