1. Upload of files such as word Excel TXT Image in Python django framework,
1. File Upload (input tag)

(1) html code (form is submitted using the post method)

1 <input class = "btn-primary col-md-1" style = "margin: 0px 15px 25px 15px; "id =" submitForm "type =" button "value =" Submit "/> 2 <form id =" picture_form "action ="/addForm/"enctype =" multipart/form- data "method =" post "> 3 <table> 4 table 5 </table> 6 </form>

(2) Submit the jq form to the background

1 $ ("# submitForm "). click (function () {2 // alert ($ ("# SelectBus "). val (); 3 addNameForm (); // because the content of the dynamically loaded form is used, the name value of the tag given by the function is 4 $. ajaxSetup ({5 async: false 6}); 7 $ ("# picture_form "). ajaxSubmit ({8 resetForm: false, 9 dataType: 'json', 10 success: function (data) {11 if (data = 1) {alert ("submitted successfully ");} 12 else {alert ("failed to submit") ;}13} 14}); 15 });

(3) The python background processes the content transmitted by the form, mainly for file processing.

1 # custom storage Path 2 rollfileName = "webStatic/uploadfile/files/" 3 rollfilePath = OS. path. join (basePath, rollfileName) 4 # req. POST. get (text [1], '') if the information is obtained, the value is not 123. if it is null, the result of not obtaining the information is 123 5 if req. POST. get (text [1], '000000') = '000000': 6 # obtain the binary stream of a file. 7. reqfile = req. FILES [text [1] 8 # Get file name suffix 9 filetype = reqfile. name. split (". ") [-1] 10 # generate a random string with a suffix named 11 filename = str (uuid. uuid1 () + '. '+ filetype12 # open the file storage path 13 of = open (rollfilePath + filename, 'wb +') 14 # Write the file to the specified path 15 for chunk in reqfile. chunks (): 16. write (chunk) # write content 17. close () # close connection 18 # store the path rollfileName + filename in the database

(4) packages used for python background processing

1 # generate unordered string, replace file name 2 import uuid
