C#中UriComponents枚举的实现示例

using System;
using UnityEngine;

public class UriComponentsTest : MonoBehaviour
{
    private void Start()
    {
        string uriString = "https://user:password@example.com:8080/api/users?id=123#section1";
        Uri uri = new Uri(uriString);
        UriFormat format = UriFormat.Unescaped;//不转义特殊字符

        //1. SerializationInfoString：内部序列化使用（外部调用无实际意义）
        string serializationInfo = uri.GetComponents(UriComponents.SerializationInfoString, format);
        Debug.Log($"SerializationInfoString: {serializationInfo}");
        //输出：SerializationInfoString: https://user:password@example.com:8080/api/users?id=123#section1

        //2. Scheme：提取协议部分
        string scheme = uri.GetComponents(UriComponents.Scheme, format);
        Debug.Log($"Scheme: {scheme}");
        //输出：Scheme: https

        //3. UserInfo：提取用户信息（用户名:密码）
        string userInfo = uri.GetComponents(UriComponents.UserInfo, format);
        Debug.Log($"UserInfo: {userInfo}");
        //输出：UserInfo: user:password

        //4. Host：提取主机名
        string host = uri.GetComponents(UriComponents.Host, format);
        Debug.Log($"Host: {host}");
        //输出：Host: example.com

        //5. Port：提取端口号（默认端口返回-1）
        string port = uri.GetComponents(UriComponents.Port, format);
        Debug.Log($"Port: {port}");
        //输出：Port: 8080

        //6. SchemeAndServer：协议+用户信息+主机+端口（1|2|4|8=13）
        string schemeAndServer = uri.GetComponents(UriComponents.SchemeAndServer, format);
        Debug.Log($"SchemeAndServer: {schemeAndServer}");
        //输出：SchemeAndServer: https://user:password@example.com:8080

        //7. Path：提取路径部分
        string path = uri.GetComponents(UriComponents.Path, format);
        Debug.Log($"Path: {path}");
        //输出：Path: /api/users

        //8. Query：提取查询字符串（不含?）
        string query = uri.GetComponents(UriComponents.Query, format);
        Debug.Log($"Query: {query}");
        //输出：Query: id=123

        //9. PathAndQuery：路径+查询字符串（16|32=48）
        string pathAndQuery = uri.GetComponents(UriComponents.PathAndQuery, format);
        Debug.Log($"PathAndQuery: {pathAndQuery}");
        //输出：PathAndQuery: /api/users?id=123

        //10. HttpRequestUrl：HTTP请求完整路径（13|48=61）
        string httpRequestUrl = uri.GetComponents(UriComponents.HttpRequestUrl, format);
        Debug.Log($"HttpRequestUrl: {httpRequestUrl}");
        //输出：HttpRequestUrl: https://user:password@example.com:8080/api/users?id=123

        //11. Fragment：提取片段（锚点，不含#）
        string fragment = uri.GetComponents(UriComponents.Fragment, format);
        Debug.Log($"Fragment: {fragment}");
        //输出：Fragment: section1

        //12. AbsoluteUri：完整URI（13|48|64=127）
        string absoluteUri = uri.GetComponents(UriComponents.AbsoluteUri, format);
        Debug.Log($"AbsoluteUri: {absoluteUri}");
        //输出：AbsoluteUri: https://user:password@example.com:8080/api/users?id=123#section1

        //13. StrongPort：强制返回实际端口（包括默认端口）
        string strongPort = uri.GetComponents(UriComponents.StrongPort, format);
        Debug.Log($"StrongPort: {strongPort}");
        //输出：StrongPort: 8080

        //14. HostAndPort：主机+显式端口（4|8|128=132）
        string hostAndPort = uri.GetComponents(UriComponents.HostAndPort, format);
        Debug.Log($"HostAndPort: {hostAndPort}");
        //输出：HostAndPort: example.com:8080

        //15. StrongAuthority：用户信息+主机+显式端口（2|132=134）
        string strongAuthority = uri.GetComponents(UriComponents.StrongAuthority, format);
        Debug.Log($"StrongAuthority: {strongAuthority}");
        //输出：StrongAuthority: user:password@example.com:8080

        //16. NormalizedHost：标准化主机名（小写+IDN处理）
        string normalizedHost = uri.GetComponents(UriComponents.NormalizedHost, format);
        Debug.Log($"NormalizedHost: {normalizedHost}");
        //输出：NormalizedHost: example.com

        //17. KeepDelimiter：保留?分隔符（需与其他成员组合）
        string queryWithDelimiter = uri.GetComponents(UriComponents.Query | UriComponents.KeepDelimiter, format);
        Debug.Log($"Query | KeepDelimiter: {queryWithDelimiter}");
        //输出：Query | KeepDelimiter: ?id=123
    }
