Java URI getPath()方法及示例
getPath()函数是URI类的一部分。函数getPath()返回指定URI的路径名称。
函数签名:
public String getPath()
语法:
url.getPath()
参数 :该函数不需要任何参数
返回类型: 该函数返回字符串类型
下面的程序说明了getPath()函数的使用。
例1: 给定一个URI,我们将使用getPath()函数获得路径。
// Java program to show the
// use of the function getPath()
import java.net.*;
class Solution {
public static void main(String args[])
{
// uri object
URI uri = null;
try {
// create a URI
uri = new URI("https://www.geeksforgeeks.org/url-getprotocol-method-in-java-with-examples/");
// get the Path
String _Path = uri.getPath();
// display the URI
System.out.println("URI = " + uri);
// display the Path
System.out.println(" Path=" + _Path);
}
// if any error occurs
catch (URISyntaxException e) {
// display the error
System.out.println("URI Exception =" + e.getMessage());
}
}
}
输出:
URI = https://www.geeksforgeeks.org/url-getprotocol-method-in-java-with-examples/
Path=/url-getprotocol-method-in-java-with-examples/
例2: getPath()和getRawPath()返回的值是一样的,只是所有转义的八位数序列都被解码了。getRawPath()返回用户提供的字符串的准确值,但getPath()函数对转义八位字节的序列(如果有的话)进行解码。
// Java program to show the
// use of the function getPath()
import java.net.*;
class Solution {
public static void main(String args[])
{
// uri object
URI uri = null;
try {
// create a URI
uri = new URI("https://www.geeksforgeeks.org/url-getprotocol-method-in-java-with-examples%E2%82%AC/");
// get the Path
String _Path = uri.getPath();
// get the Raw Path
String Raw_Path = uri.getRawPath();
// display the URI
System.out.println("URI = " + uri);
// display the Path
System.out.println(" Path=" + _Path);
// display the Raw_Path
System.out.println(" Raw Path=" + Raw_Path);
}
// if any error occurs
catch (URISyntaxException e) {
// display the error
System.out.println("URI Exception =" + e.getMessage());
}
}
}
输出:
URI = https://www.geeksforgeeks.org/url-getprotocol-method-in-java-with-examples%E2%82%AC/
Path=/url-getprotocol-method-in-java-with-examples?/
Raw Path=/url-getprotocol-method-in-java-with-examples%E2%82%AC/
