Question

我从多个api获取数据并将其渲染到<Pickers />中，但问题是我无法在此axios.all方法中为Auth分配标题。请为我提供解决方案或犯错。

axios.all([
        axios.get(this.apiUrl + '/case/GetCaseType'),
        axios.get(this.apiUrl + '/case/GetCasePriority')
    ], { headers: { 'authorization': 'bearer ' + this.state.jwtToken } })
        .then(axios.spread(( response2, response3) => {
            console.log('Response 1: ', response1.data.retrn);
            console.log('Response 2: ', response2.data.retrn);
            console.log('Response 3: ', response3.data.retrn);
            this.hideLoader();
        })).catch(error => console.log(error.response));

您可以使用配置并创建实例来设置url, token, timeout等常见内容

import axios from 'axios';
const http = axios.create({
      baseURL: this.url,
      timeout: 5000
});

http.defaults.headers.common['authorization'] = `bearer ${this.state.jwtToken}`

export async function yourAPIcallMethod(){
   try{
       const [res1,res2] = await http.all([getOneThing(), getOtherThing()]);
       //when all responses arrive then below will run
       //res1.data and res2.data will have your returned data
       console.log(res1.data, res2.data)
       //i will simply return them
       return {One: res1.data, Two: res2.data}
      }
   catch(error){
      console.error(error.message || "your message")
      }
}

这可以在您的component.jsx中使用

import {yourAPIcallMethod} from './httpService';

async componentDidMount(){
    const data = await yourAPIcallMethod();
    this.setState({One: data.One, Two: data.Two})
}

您可以在github axios上查看和了解更多信息。

您可以创建一个服务文件来处理所有对GET或POST的请求，将使用Autherization标头处理GET请求的文件给定

GetService.js

import axios from 'axios'; 
let constant = {
    baseurl:'https://www.sampleurl.com/'
};
let config = {    
    headers: {
    'Content-Type': 'multipart/form-data',
    'Accept': 'application/json'
    }
};

export const GetService = (data,Path,jwtKey) => {
    // jwtKey is null then get request will be send without header, ie for public urls
    if(jwtKey != ''){
        axios.defaults.headers.common['Authorization'] = 'Bearer '+jwtKey;
    }

    try{
        return axios.get(
                            constant.baseUrl+'api/'+Path, 
                            data, 
                            config
                        );
    }catch(error){
        console.warn(error);
    }
}
