二、实战核心代码解析
1. 基础URL解析
实现最基本的URL解析功能。
javascript
import { useState } from 'react';
import { View, Text, TouchableOpacity, StyleSheet, TextInput } from 'react-native';
const URLParser = () => {
const [url, setUrl] = useState<string>('https://example.com/path?name=John&age=30');
// 解析URL
const parseURL = (urlString: string): { protocol: string; host: string; path: string; query: Record<string, string> } => {
try {
// 使用正则表达式解析URL
const urlPattern = /^(https?:\/\/)?([^\/:\?#]+)(?::(\d+))?([^\?#]*)(\?([^#]*))?(#(.*))?$/i;
const match = urlString.match(urlPattern);
if (!match) {
return { protocol: '', host: '', path: '', query: {} };
}
const [, protocol, host, port, path, , queryString, hash] = match;
const query: Record<string, string> = {};
if (queryString) {
queryString.split('&').forEach(param => {
const [key, value] = param.split('=');
if (key) {
query[key] = value || '';
}
});
}
return {
protocol: protocol ? (protocol.includes('https') ? 'https:' : 'http:') : '',
host: host || '',
path: path || '',
query,
};
} catch (error) {
return { protocol: '', host: '', path: '', query: {} };
}
};
// 获取查询参数
const getQueryParam = (urlString: string, param: string): string | null => {
try {
const urlParts = urlString.split('?');
if (urlParts.length < 2) return null;
const queryString = urlParts[1];
const params = queryString.split('&');
for (const param of params) {
const [paramKey, paramValue] = param.split('=');
if (paramKey === param) {
return paramValue || '';
}
}
return null;
} catch (error) {
return null;
}
};
const parsed = parseURL(url);
return (
<View style={styles.container}>
<TextInput
style={styles.input}
value={url}
onChangeText={setUrl}
placeholder="输入URL"
/>
<Text style={styles.resultText}>协议: {parsed.protocol}</Text>
<Text style={styles.resultText}>主机: {parsed.host}</Text>
<Text style={styles.resultText}>路径: {parsed.path}</Text>
<Text style={styles.resultText}>查询参数: {JSON.stringify(parsed.query)}</Text>
</View>
);
};
const styles = StyleSheet.create({
container: {
padding: 20,
},
input: {
borderWidth: 1,
borderColor: '#DCDFE6',
borderRadius: 8,
padding: 12,
marginBottom: 12,
fontSize: 16,
},
resultText: {
fontSize: 16,
color: '#303133',
marginBottom: 8,
},
});
export default URLParser;
核心要点:
- 使用URL对象解析URL
- 提取协议、主机、路径等
- 解析查询参数
- 鸿蒙端URL解析正常
2. URL构建
实现URL构建功能。
javascript
// 构建URL
const buildURL = (base: string, path: string, params: Record<string, string> = {}): string => {
try {
// 组合基础URL和路径
let url = base;
if (path) {
const cleanBase = url.replace(/\/$/, '');
const cleanPath = path.replace(/^\//, '');
url = `${cleanBase}/${cleanPath}`;
}
// 添加查询参数
const paramKeys = Object.keys(params);
if (paramKeys.length > 0) {
const queryString = paramKeys
.map(key => `${encodeURIComponent(key)}=${encodeURIComponent(params[key])}`)
.join('&');
url = `${url}?${queryString}`;
}
return url;
} catch (error) {
return base;
}
};
// 添加查询参数
const addQueryParams = (urlString: string, params: Record<string, string>): string => {
try {
const separator = urlString.includes('?') ? '&' : '?';
const queryString = Object.entries(params)
.map(([key, value]) => `${encodeURIComponent(key)}=${encodeURIComponent(value)}`)
.join('&');
return `${urlString}${separator}${queryString}`;
} catch (error) {
return urlString;
}
};
return url.toString();
} catch (error) {
return urlString;
}
};
// 移除查询参数
const removeQueryParam = (urlString: string, param: string): string => {
try {
const urlParts = urlString.split('?');
if (urlParts.length < 2) return urlString;
const baseUrl = urlParts[0];
const queryString = urlParts[1];
const params = queryString.split('&').filter(urlParam => {
const [paramKey] = urlParam.split('=');
return paramKey !== param;
});
return params.length > 0 ? `${baseUrl}?${params.join('&')}` : baseUrl;
} catch (error) {
return urlString;
}
};
// 使用示例
const builtURL = buildURL('https://example.com', '/api/users', { page: '1', limit: '10' });
const withParams = addQueryParams('https://example.com', { name: 'John', age: '30' });
const withoutParam = removeQueryParam('https://example.com?name=John&age=30', 'age');
核心要点:
- 使用URL对象构建URL
- 添加查询参数
- 移除查询参数
- 鸿蒙端URL构建正常
3. URL验证
实现URL验证功能。
javascript
// 验证URL
const isValidURL = (urlString: string): boolean => {
try {
// 更严格的URL验证正则表达式
// 1. 必须包含协议(http:// 或 https://)
// 2. 域名部分必须有效(至少一个点号,点号后2-20个字母)
// 3. 支持路径、查询参数和hash
const urlPattern = /^https?:\/\/([\da-z\.-]+)\.([a-z]{2,20})(:[0-9]+)?([\/\w\-._~%!$&'()*+,;=:@/]*)*(\?[\/\w\-._~%!$&'()*+,;=:@/?]*)?(#[-\w._~%!$&'()*+,;=:@/?]*)?$/i;
return urlPattern.test(urlString);
} catch (error) {
return false;
}
};
// 验证HTTPS
const isHTTPS = (urlString: string): boolean => {
try {
const urlPattern = /^https:\/\//i;
return urlPattern.test(urlString);
} catch (error) {
return false;
}
};
// 获取域名
const getDomain = (urlString: string): string => {
try {
const urlPattern = /^https?:\/\/([^\/:]+)/;
const match = urlString.match(urlPattern);
return match ? match[1] : '';
} catch (error) {
return '';
}
};
// 使用示例
const valid = isValidURL('https://example.com');
const https = isHTTPS('https://example.com');
const domain = getDomain('https://example.com/path');
核心要点:
- 使用try-catch验证URL
- 检查协议类型
- 提取域名
- 鸿蒙端URL验证正常

// { matched: true, params: { id: '123' } }
✨ 扩展4:URL拼接
适配「URL拼接」的场景,实现URL拼接功能,只需添加拼接逻辑,无需改动核心逻辑,一行代码实现,鸿蒙端完美适配:
javascript
const joinPaths = (...paths: string[]): string => {
return paths
.map(path => path.replace(/\/+/g, '/').replace(/^\/|\/$/g, ''))
.filter(Boolean)
.join('/');
};
const joinURL = (base: string, ...paths: string[]): string => {
try {
// 解析 base URL 的各个部分
const urlPattern = /^(https?:\/\/)([^\/\?]+)(\/[^\?]*)?(\?[^#]*)?(#.*)?$/i;
const match = base.match(urlPattern);
if (match) {
const [, protocol, host, basePath = '', query = '', hash = ''] = match;
const joinedPath = joinPaths(basePath, ...paths);
return protocol + host + '/' + joinedPath + query + hash;
}
// 如果不是完整的 URL,直接拼接路径
return joinPaths(base, ...paths);
} catch (error) {
return joinPaths(base, ...paths);
}
};
// 使用示例
const joined = joinPaths('api', 'users', '123'); // "api/users/123"
const urlJoined = joinURL('https://example.com/api', 'users', '123');
// "https://example.com/api/users/123"
✨ 扩展5:URL缓存
适配「URL缓存」的场景,实现URL缓存键生成,只需添加缓存逻辑,无需改动核心逻辑,一行代码实现,鸿蒙端完美适配:
javascript

const match = url.match(urlPattern);
if (!match) return url;
const [, protocol, host, path = '', query = '', hash = ''] = match;
// 排序查询参数
let sortedQuery = '';
if (query) {
const params = query.substring(1).split('&').filter(p => p);
params.sort();
sortedQuery = params.length > 0 ? '?' + params.join('&') : '';
}
return `${protocol}${host}${path}${sortedQuery}`;
} catch (error) {
return url;
}
};
const generateETag = (url: string): string => {
const cacheKey = generateCacheKey(url);
let hash = 0;
for (let i = 0; i < cacheKey.length; i++) {
const char = cacheKey.charCodeAt(i);
hash = ((hash << 5) - hash) + char;
hash = hash & hash;
}
return Math.abs(hash).toString(36);
};
// 使用示例
const cacheKey = generateCacheKey('https://example.com/api/users?page=1&limit=10');
const etag = generateETag('https://example.com/api/users?page=1&limit=10');
