本文介绍了从空格编码图像URL的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在开发一个RSS阅读器应用程序,但由于它们包含空格,因此我遇到了图像URL的问题。我从这些论坛尝试了几种技术,但都给我不同的错误。我尝试用%20替换空间,但是我找不到文件找不到异常。
这是我获取图像的方法:
I'm developing a RSS reader app, but I'm facing problems with the image URLs becuase they contain spaces. I tried several techniques from these forums but they all give me different errors. I tried replacing the space with %20 but I'm getting file not found exception.This is the method in which I'm fetching the image:
//String ALLOWED_URI_CHARS = "@#&=*+-_.,:!?()/~'%";
//url = Uri.encode(url, ALLOWED_URI_CHARS);
//URL urlnew = new URL(url);
//URI uri = new URI(urlnew.getProtocol(), urlnew.getUserInfo(), urlnew.getHost(), urlnew.getPort(), urlnew.getPath(), urlnew.getQuery(), urlnew.getRef());
//urlnew = uri.toURL();
//url = URLEncoder.encode(url.replace(" ", "%20"), "utf-8");
url = url.replaceAll(" ", "%20");
Bitmap bitmap=null;
URL imageUrl = new URL(url);
HttpURLConnection conn = (HttpURLConnection)imageUrl.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("GET");
Log.i("Code:",conn.getResponseCode()+" "+conn.getResponseMessage());
Log.i("Error Message",conn.getErrorStream()+"");
conn.setConnectTimeout(30000);
conn.setReadTimeout(30000);
conn.setInstanceFollowRedirects(true);
InputStream is=conn.getInputStream();
OutputStream os = new FileOutputStream(f);
Utils.CopyStream(is, os);
os.close();
conn.disconnect();
bitmap = decodeFile(f);
return bitmap;
顶部的注释命令是我从其他人那里得到的一些命令。

如果我将含有%20的编码URL插入到浏览器中,图像将正常打开,以便链接正常工作。
If I insert the encoded URL which contains %20 into the browser the image opens normally so the links are working.
推荐答案
String urlStr = "http://abc.dev.domain.com/0007AC/ads/800x480 15sec h.264.mp4";
URL url = new URL(urlStr);
URI uri = new URI(url.getProtocol(), url.getUserInfo(), url.getHost(), url.getPort(), url.getPath(), url.getQuery(), url.getRef());
url = uri.toURL();
