Fetch HTTP Client 基于 Fetch API 封装的 HTTP Client 项目简介
一个基于 Fetch API 封装的 HTTP Client,可用于浏览器及其他兼容环境中,设计之初是为了ReactJS和ReactNative访问后端RestAPI使用。比其他基于Fetch API的封装优势在于,它的中间件机制支持对请求和应答进行异步处理。安装:npm install fetch-http-client --save使用:import FetchHttpClient, { json } from 'fetch-http-client';
// Create a new client object.
const client = new FetchHttpClient('http://api.example.com/endpoint');
// Add access token
client.addMiddleware(request => {
request.options.headers['X-Access-Token'] = 'secret';
});
// Add json support
client.addMiddleware(json());
// Add Logging
client.addMiddleware(request => response => {
console.log(request, response);
});
// Fire request.
client.get('test').then(response => console.log(response.jsonData));
// Path variables support.
client.get('users/{id}', { uriParams: { id: 1 } }).then(response => console.log(response.jsonData));预处理异步请求的中间件示例,从存储中异步读取accessToken,并添加到请求头中:// Add access token asynchronously
client.addMiddleware(request => {
return AsynchronousStorage.fetch('accessToken').then(token => {
request.options.headers['X-Access-Token'] = token;
return request;
});
});
