Design And Implementation Of File Search And Download Service System In Mobile Internet Environment

Since the official birth of the Internet in the 1990 s,it has developed for decades.Now the mobile Internet has become the most important part of the Internet.A variety of mobile Internet applications such as music,video,games,and payment have developed rapidly.Among them,watching videos is an indispensable way of entertainment and learning.With the development of technology,people have higher requirements for video entertainment such as higher requirements for the definition,frame rate,and screen size of the video.At the same time,as the interaction between TV and smartphone becomes stronger and stronger,while realizing efficient and natural interaction.Smart TV can also be well linked with other devices such as mobile phones,and at the same time it can become a home Io T control terminal.Therefore,this paper hopes to combine the advantages of smart TV and mobile Internet.On the one hand,we hope to provide users with a better viewing experience through smart TV.On the other hand,we hope to give full play to the interactivity of smart mobile devices and the richness of mobile Internet resources to provide users with rich video resources.Based on this purpose,this thesis designs a file search and download service system in the mobile Internet environment to meet the above needs of users.First,we use web crawler technology to crawl video resources for different resource websites,including basic information of video,resource links,piracy sources,etc.After that,the validity of various resource links is verified,and then marked in the database.Secondly,this thesis also designs a vertical search engine for video resources.Firstly,we index the data through the data index server technology,and provide a search interface based on HTTP / HTTPS protocol to return query results in JSON format.In order to process the data returned by the data index server,this thesis compiles a web page similar to Baidu search through Java Script and bootstrap and puts it on the server.Users can carry out accurate search,classified search,etc.on the web page.The website will process the data returned by the server and finally display the basic information and download links of the search content to users.Finally,this thesis also designs a multi terminal interactive system,which designs and realizes the interactive functions of TV terminal,PC terminal and mobile device terminal respectively.The app of mobile terminal controls the TV terminal and PC terminal to download and transfer files,and then play them on TV terminal.At the same time,for specific forum resource websites,a series of functions such as account management are also provided to help users better obtain content resources.
