如何在Java中解析此URL

Question

我有這樣的網址

http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=

我需要鍵值對而不是查詢字符串。

我的輸出應該是

mailParams = iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=

由於上面已編碼，我無法解析此字符串。 我已經使用URLEncodedUtils來解析它，但是它返回

mailParams = iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ vx43P4g umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW KjUi3JubtJT 0F7p wPHEpTRwJJ O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA 

哪個根本不相關，有人可以幫助我做到這一點嗎？

Answer 1

嘗試使用java.net.URL

下面的示例代碼。

    URL aURL = new URL("http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=");

    System.out.println("protocol = " + aURL.getProtocol());
    System.out.println("authority = " + aURL.getAuthority());
    System.out.println("host = " + aURL.getHost());
    System.out.println("port = " + aURL.getPort());
    System.out.println("path = " + aURL.getPath());
    System.out.println("query = " + aURL.getQuery());
    System.out.println("filename = " + aURL.getFile());
    System.out.println("ref = " + aURL.getRef());

如果需要拆分鏈接以獲取參數

使用String#split將正則表達式作為參數

String link="http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=";
        String[] mailparams=link.split("\\?");
        System.out.print(mailparams[1]);

您也可以使用URL#getQuery

String link="http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=";
         URL aURL = new URL(link);
        System.out.println( aURL.getQuery());

輸出 ：

mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=

URL aURL = null;
try {
    aURL = new URL("http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=");
} catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

System.out.println(aURL.getQuery());
