OutputStreamWriter out=new OutputStreamWriter(uc.getOutputStream(),"UTF-8");
out.write(str);
out.write("\r\n");
out.flush();
return uc.getInputStream();

}
public static void main(String args[]) throws IOException

{
URL url=new URL("https://www.zhihu.com/#signin");
FormPoster poster=new FormPoster();
InputStream in=poster.post(url);
InputStreamReader theHTML=new InputStreamReader(in,"UTF-8");
int c;
while((c=theHTML.read())!=-1)
{
System.out.print((char)c);
}

}
}
下面是报错的信息Exception in thread "main" java.io.IOException: Server returned HTTP response code: 403 for URL: https://www.zhihu.com/#signin
