Interceptor API
拦截器管理器，用于添加和管理请求/响应拦截器。
InterceptorManager
addRequestInterceptor()
添加请求拦截器。
typescript
addRequestInterceptor(interceptor: RequestInterceptor): () => void参数：
typescript
interface RequestInterceptor {
onRequest?(config: RequestOptions): Promise<RequestOptions> | RequestOptions;
onRequestError?(error: any): Promise<any>;
}返回值： 返回一个函数，调用该函数可以移除此拦截器。
示例：
typescript
const removeInterceptor = request.interceptors.addRequestInterceptor({
onRequest: (config) => {
config.headers = {
...config.headers,
'Authorization': `Bearer ${token}`
};
return config;
},
onRequestError: (error) => {
console.error('Request error:', error);
throw error;
}
});
// 移除拦截器
removeInterceptor();addResponseInterceptor()
添加响应拦截器。
typescript
addResponseInterceptor(interceptor: ResponseInterceptor): () => void参数：
typescript
interface ResponseInterceptor {
onResponse?<T>(response: Response<T>): Promise<Response<T>> | Response<T>;
onResponseError?(error: RequestError): Promise<any>;
}返回值： 返回一个函数，调用该函数可以移除此拦截器。
示例：
typescript
const removeInterceptor = request.interceptors.addResponseInterceptor({
onResponse: (response) => {
console.log('Response:', response.status);
return response;
},
onResponseError: (error) => {
console.error('Response error:', error);
throw error;
}
});
// 移除拦截器
removeInterceptor();类型定义
RequestInterceptor
typescript
interface RequestInterceptor {
onRequest?(config: RequestOptions): Promise<RequestOptions> | RequestOptions;
onRequestError?(error: any): Promise<any>;
}ResponseInterceptor
typescript
interface ResponseInterceptor {
onResponse?<T>(response: Response<T>): Promise<Response<T>> | Response<T>;
onResponseError?(error: RequestError): Promise<any>;
}RequestOptions
typescript
interface RequestOptions {
method?: string;
url?: string;
data?: any;
headers?: Record<string, string>;
params?: Record<string, any>;
timeout?: number;
[key: string]: any;
}Response
typescript
interface Response<T> {
data: T;
status: number;
statusText: string;
headers: Record<string, string>;
config: RequestOptions;
}完整示例
typescript
import { Request } from '@ureq/core';
import { FetchRequestor } from '@ureq/impl-fetch';
const request = new Request(new FetchRequestor());
// 添加请求拦截器
request.interceptors.addRequestInterceptor({
onRequest: (config) => {
// 添加 token
const token = localStorage.getItem('token');
if (token) {
config.headers = {
...config.headers,
'Authorization': `Bearer ${token}`
};
}
// 添加时间戳
config.params = {
...config.params,
_t: Date.now()
};
return config;
}
});
// 添加响应拦截器
request.interceptors.addResponseInterceptor({
onResponse: (response) => {
// 统一处理响应数据
if (response.data.code === 0) {
return {
...response,
data: response.data.data
};
} else {
throw new Error(response.data.message);
}
},
onResponseError: (error) => {
// 统一错误处理
if (error.status === 401) {
localStorage.removeItem('token');
window.location.href = '/login';
}
throw error;
}
});
