本来不想记录，但是实在没有办法，因为总是会出现post请求，后台接收不到数据的情况,还是记录一下如何的解决的比较好。
但是我使用export const addPsiPurOrder = data => request.post('/psi/psiPurOrder/add', data);
下面是封装的代码。后台接收不到数据.

出现问题的主要原因是java对象中如果有日期字段，且这些字段从前台传给后端，一定要加上下面的字段。需要加上下面的配置，

import axios, { AxiosRequestConfig, AxiosInstance } from 'axios'
import { baseURL } from '@/config/domain'
import { TokenName } from '@/config/const'
import { useAppStoreWithOut } from '@/store'
import { usePermission } from '@/hooks'
import router from '@/router'
import { localMng } from '@/utils/storage-mng'

class Request {
	private baseConfig: AxiosRequestConfig = {
		baseURL,
		headers: {
			'Group':'xxxx',
			'Tenat':'yyyy',
			'source': 'zzzz',
		},
		timeout: 10000,
	}

	private instance: AxiosInstance = axios.create(this.baseConfig)

	public constructor() {
		const token = localMng.getItem(TokenName)
		if (token) {
			this.setHeader({
				Authorization: token,
			})
		} else {
			this.initInstance()
		}
	}

	private initInstance() {
		this.instance = axios.create(this.baseConfig)
		this.setReqInterceptors()
		this.setResInterceptors()
	}

	// 请求拦截器
	private setReqInterceptors = () => {
		this.instance.interceptors.request.use(
			config => {
				// const { checkApiPermission } = usePermission()
				config.cancelToken = new axios.CancelToken(function executor(c) {
					// if (!checkApiPermission(config.url)) {
					//   c(config.url + '没有权限')
					//   router.push('/error/forbidden')
					// }
				})
				// console.log(`%c++++++ 开始请求：${config.url} ++++++`, 'color:green')
				// console.log(config.data)
				// console.log(`%c++++++ end ++++++`, 'color:green')
				return config
			},
			err => {
				window.$message.error('请求失败')
				return Promise.reject(err)
			}
		)
	}

	// 响应拦截器
	private setResInterceptors = () => {
		this.instance.interceptors.response.use(
			res => {
				let { success, code, body, msg } = res.data
				if(success || (!code || code == 200 || code == '0000')){ code = 200 }
				switch (code*1) {
					case 200:
						console.log(res.data,'res');
						return Promise.resolve(body || res.data)
					case 40301:
						window.$message.warning(msg || '无权限')
						const appStore = useAppStoreWithOut()
						appStore.logout()
						return Promise.reject(res.data)
					default:
						window.$message.error(msg || '响应失败')
						return Promise.reject(res.data)
				}
			},
			err => {
				if (!axios.isCancel(err)) {
					window.$message.error('响应失败')
				}
				return Promise.reject(err)
			}
		)
	}
