vue中三种调用接口的方法
作者：加蓓努力我先飞
这篇文章主要介绍了vue中三种调用接口的方法，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教
1. this.$api.LeadershipScreen.getImportantRiskList(params)
在api文件下层级关系如下图：
在index.js下
// 导入所有接口
import api from './api'
const install = Vue => {
if (install.installed)
return;
install.installed = true;
Object.defineProperties(Vue.prototype, {
// 注意，此处挂载在 Vue 原型的 $api 对象上
$api: {
get() {
return api
}
}
})
}
export default install
在api.js
/*接口统一模块*/
import * as LeadershipScreen from './componet/LeadershipScreen'
export default {
LeadershipScreen
}
/*使用模板
* this.$api.auditApi.auditDataAll().then(response=>{
}).catch(error=>{
})
*/
在componet/LeadershipScreen.js
import { request } from "../../utils/request6";
export const getImportantRiskList = (data) => {
//allUrl2 可以写一个公共的地方将allUrl2 引进来
return request({
method: 'get',
url: allUrl2 + '/important/getImportantRiskList',
data
});
};
在页面中使用
this.$api.LeadershipScreen
.getImportantRiskList(params)
.then((res) => {
console.log("res.data111111111111", res.data);
this.getList = res.data;
})
.catch((error) => {});
//methodName:null;
let params={}
this.methodName = this.$api.LeadershipScreen.getImportantRiskList;
this.methodName(params)
.then((res) => {
console.log("res", res);
})
.catch((error) => {});
2.需要引用
定义
import request from '@/utils/request'
export const selectTaskInfo = (id, params) => request({ url: '/project-mgt/project/v1.0/selectTaskInfo?taskId=' + id, method: 'get', params })
export function setFormulaConfig(params) { return request({ url: '/project-mgt/project/v1.0/formulaConfig', method: 'get', params }) }//此处的params，会自动将参数拼在后面，data则不会
export const projectSelectionAdd = (data) => request({ url: '/project-mgt/project/v1.0/add', method: 'post', data })
使用
import {
selectTaskInfo,
setFormulaConfig,
projectSelectionAdd ,
} from "@/code/projectSelection/api/projectSelectionApi";
selectTaskInfo(id)
.then((res) => {
console.log("resaaaaaaaa", res.data);
})
.catch((err) => {
console.log(err);
});
//
let params = {
id: this.Form.id,
};
setFormulaConfig(params)
.then((res) => {
if (res.code == "200") {
console.log("resaaaaaaaa", res.data);
this.$message.success("成功");
}
})
.catch((err) => {
});
let interfaceName =
this.$route.query.state == "add"
? projectSelectionAdd
: projectUpdate;
interfaceName(params)
.then((res) => {
if (res.code == "200") {
this.$message.success(
this.$route.query.state == "add" ? "新增" : "修改"
);
} else {
this.$message.error(res.msg);
}
})
.catch((err) => {});
3.axios（需要先安装axios）
get
// 为给定 ID 的 user 创建请求
axios.get('/user?ID=12345')
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
// 可选地，上面的请求可以这样做
axios.get('/user', {
params: {
ID: 12345
}
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
post
axios.post('/user', {
firstName: 'Fred',
lastName: 'Flintstone'
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
https://www.kancloud.cn/yunye/axios/234845
getQuestionSurvey() {
let testUrl = "";
if (process.env.NODE_ENV === "development") {
testUrl = "http://192.168.121.2:8080";//模拟，并非真实地址
} else {
testUrl = process.env.VUE_APP_BASE_API;
}
testUrl = testUrl + "/getFillReportById/" + this.id;
axios({
method: "get",
url: testUrl,
headers: {
"Content-Type": "application/x-www-form-urlencoded",
userId: this.userId,
},
})
.then((res) => {
//if (this.state != "editAjustMent") {
// this.tableData1.forEach((item, index) => {
// for (const key in item.detailVoMap) {
// if (key.length > 17) {
// item.detailVoMap[key].fixedFlag = 0;
// }
//}
//});
//}
})
.catch((err) => {
console.log(
"err.response.data",
err.response,
err.response.data,
err.response.data.data,
err.response.data.msg
);
this.$message.error(
err.response.data.data
? err.response.data.data
: err.response.data.msg
);
});
},
4.配置request
import axios from 'axios'
import { MessageBox, Message } from 'element-ui'
import store from '@/store'
import { getToken } from '@/utils/auth'
import qs from 'qs'
import cookieStore from '@/utils/common';
// Vue.prototype.$cookieStore = cookieStore;
// create an axios instance
const service = axios.create({
baseURL: process.env.VUE_APP_BASE_API, // url = base url + request url
// withCredentials: true, // send cookies when cross-domain requests
timeout: 500000000 // request timeout
})
// request interceptor
service.interceptors.request.use(
config => {
// do something before request is sent
if (config.requestType === 'form') {
config.headers = { 'content-type': 'application/x-www-form-urlencoded;charset=UTF-8' }
console.log('form')
config.data = qs.stringify(config.data, { indices: false })
} else if (config.requestType === 'json' || !config.requestType) {
console.log('json')
config.headers = { 'content-type': 'application/json;charset=UTF-8' }
}
if (store.getters.token) {
config.headers['Authorization'] = getToken()
}
config.headers['userId'] = "1036465471609819137"; //1
return config
},
error => {
// do something with request error
console.log(error) // for debug
return Promise.reject(error)
}
)
// response interceptor
service.interceptors.response.use(
response => {
const res = response.data
if (res.code == 200) {
return Promise.resolve(res)
} else if (res.code == 0) {
return Promise.resolve(res)
} else if (res.code == 401) {
Message.error(res.msg)
store.dispatch('user/resetToken').then(() => {
location.reload()
})
} else if (res.code == 20000) {
return Promise.resolve(res)
} else {
Message({
message: res.msg,
type: 'error'
})
return Promise.reject(res)
}
},
error => {
console.log('err' + error) // for debug
console.log(error.response)
Message({
message: error.response.data.data ? error.response.data.data : error.response.data.msg,
type: 'error',
duration: 5 * 1000
})
return Promise.reject(error.response)//此操作，可以直接拿到报错的信息error.response
}
)
export default service
