| In recent years,with the development of electronic commerce and material base,online shopping has become an indispensable part of life,but also promote the development of city logistics.Along with moving,various kinds of distribution in the same city constantly emerged.City freight has become a major industry derived from electronic commerce.However,for a long time,there are some drawbacks in City freight of China,such as asymmetric information of vehicle supply and demand,piecemeal of transportation resources and delivery requirements,and poor service experience.All these restrict the healthy development of the city freight industry.Integration of Internet technology and traditional industry and the rise of a number of freight platforms have effectively solved these problems.Initially,freight platforms showed explosive growth,and now they are showing a more and more rational development model.For example,they pay more and more attention to using intelligent means to meet the diversified needs of customers and the rational scheduling of resources.The purpose of this paper is to integrate the unplanned delivery demand and disorganized capacity resources in city freight market by using Internet technology,which can not only greatly shorten the intermediate links,but also solve the waste of resources.Standardized management of vehicle source information,source information,transportation price and operation process can better solve the problem of difficult market supervision.It is also very important to improve the construction of the city freight platform and make full use of the social transportation resources to improve the transportation efficiency.It is also of great significance to improve the construction of city freight platform and to make full use of social transportation resources to improve transportation efficiency.In this paper,based on the actual demand of the same city freight platform,a comprehensive information platform for Didi freight is designed and implemented.The design of platform uses a REST-style front-end and back-end separation architecture and the popular front-end and back-end separation development technology Django REST framewrok(DRF)+ Vue.The platform back-end is implemented by using the Django framework.The open source relational database MySQL and the Xadmin management backend are installed in this framework to achieve a high efficient website structure.RESTful API is rapidly constructed by Django REST framework to only return the front-end data required.The front-end of the platform uses the Vue framework,and Webpack is used to achieve high-performance component development to greatly improve the development efficiency.As a result,the front-end and back-end are separated.The back-end does not need to control the front-end page and display effect,but only needs to return the data needed by the front-end.How to get the data and display the effect of the page is decided by the front-end itself,which makes the coupling degree between the front end and the back end relatively low.The design and implementation of the integrated information platform for Didi freight are introduced in detail from the aspects of demand analysis,overall design,detailed design and implementation,and system testing.The functions of the platform are as follows:(1)providing member users with online order placing,payment order,order evaluation,and manage order information,integral information and basic information of this account;(2)providing the driver user with order preemption,and manage the order information,integral information,personal basic information,certificate information and vehicle information of this account;(3)providing background administrators with platform initial information management,user management,order management,positioning management,assessment management,settlement management,online message management.This facilitates the transportation of goods in the city,effectively saves resources and reduces logistics costs. |
