HarmonyOS 鸿蒙Next 在使用axios进行post请求发送参数后台nginx无法获取参数，尝试设置contentType也无法获取到

// post请求 \ post(url:string,map?:Map<string,string>,isList?:string){ axios.defaults.headers.post[‘Content-Type’] = ‘application/x-www-form-urlencoded’; return axios<NormalResultModel,AxiosResponse<NormalResultModel>>({ url: url, method: ‘post’, params: CryptoUtils.mapToObject(map), headers: CryptoUtils.signRequest(BuildProfile.REQUEST_SIGN_AGENT,BuildProfile.REQUEST_SIGN_SECRET,map), }).then((res: AxiosResponse<NormalResultModel>) => { let status = res ? res.status : ‘’; let message = res ? JSON.stringify(res.data) : ‘’; let code =res.data.code let  data =res.data.data if (code!=0){ ToastUtil.showShort(data as string) } if (‘list’==isList) { return ( data as ListDataModel).list; }else { return data; } }).catch((err: AxiosError) => { // 如果是token过期或者格式错误的异常则重新刷新token let jwtExpired = “security_005” let jwtFormatError = “security_006” let errCode=err.code let status = ‘’; let message = err.message; let endTime = new Date().getTime(); return message; }); }
