1、文件上傳(input標(biāo)簽)
(1)html代碼(form表單用post方法提交)

< input class = "btn btn-primary col-md-1" style = "margin:0px 15px 25px 15px;" id = "submitForm" type = "button" value = "提交" /> < form id = "picture_form" action = "/addForm/" enctype = "multipart/form-data" method = "post" > < table > 表格 </ table > </ form > |
(2)jq提交表單到后臺

$( "#submitForm" ).click(function(){ / / alert($( "#SelectBus" ).val()); addNameForm(); / / 因?yàn)槭莿討B(tài)加載的表單內(nèi)容,所以會用函數(shù)給所用標(biāo)簽符name值 $.ajaxSetup({ async : false }); $( "#picture_form" ).ajaxSubmit({ resetForm:false, dataType: 'json' , success:function(data){ if (data = 1 ){alert( "提交成功" );} else {alert( "提交失敗" );} } }); }); |
(3)python后臺接受處理表單所傳內(nèi)容,主要file處理

#自定義存儲路徑 rollfileName = "webStatic/uploadfile/files/" rollfilePath = os.path.join(basePath,rollfileName) # req.POST.get(text[1],'')如果獲取到信息,則值不是123,如果是空,沒有獲取到信息結(jié)果是123 if req.POST.get(text[ 1 ], '123' ) = = '123' : # 獲取文件二進(jìn)制流 reqfile = req.FILES[text[ 1 ]] # 獲取文件名后綴 filetype = reqfile.name.split( "." )[ - 1 ] # 生成隨機(jī)字符串加后綴的文件名 filename = str (uuid.uuid1()) + '.' + filetype # 打開文件存儲路徑 of = open (rollfilePath + filename, 'wb+' ) # 向指定路徑寫入文件 for chunk in reqfile.chunks(): of.write(chunk) #寫入內(nèi)容 of.close() #關(guān)閉連接 |
18 #在數(shù)據(jù)庫中存儲路徑rollfileName+filename
(4)python后臺處理用到的包
1 #生成無序字符串,替換文件名
2 import uuid
