php urlencode與java urlencode相同嗎？

Question

在PHP：

php -r "echo urlencode('["IM"]'); " 

結果是%5BIM%5D

但在Java

String text = URLEncoder.encode('["IM"]',"UTF-8"); 
System.out.println("text" + text); 

結果是text%5B%22IM%22%5D

什麼是這兩個函數之間的不同？我怎樣才能實現一個Java代碼來完成相同的功能的PHP？

Answer 1

php -r "echo urlencode('["IM"]'); " 

結果是％5BIM％5D因爲函數進行urlencode實際上只取字符串[IM]作爲其輸入。而在Java

String text = URLEncoder.encode('["IM"]',"UTF-8"); 

被傳遞的字符串實際上是：["IM"]產生所述值%22其是編碼串爲"的引號。

Answer 2

試圖逃跑內部qoutes

php -r "echo urlencode('[\"IM\"]'); " 

Answer 3

String text = URLEncoder.encode('[IM]',"UTF-8"); 
System.out.println("text" + text); 

給%5BIM%5D

echo urlencode('["IM"]'); 

給%5B%22IM%22%5D

echo urlencode('[IM]'); 

給%5BIM%5D

echo urlencode('[\"IM\"]'); 

給%5B%5C%22IM%5C%22%5D
