方式一:
通过form表单提交到后台
前段:
html>
lang="en">
charset="UTF-8">
Title
Django 后端:
class Upload(View): def get(self, request): return render(request, 'clashphone/test.html', { 'mould': os.path.join(BASE_DIR, 'media', 'commen'), 'MEDIA_URL': MEDIA_URL} ) def post(self, request): obj = request.FILES.get('fafafa', '1') print(obj.name) f = open(os.path.join(BASE_DIR, 'media', 'image', obj.name), 'wb') for chunk in obj.chunks(): f.write(chunk) f.close() # return render(request, 'clashphone/test.html') return HttpResponse('OK')
方式二:
通过ajax提交
前段
<div>
<input type="file" name="file" id="file_upload">
<input type="button" value="上传" onclick="FileUpload()">
div>
JS:
Django 后端:
def upload_ajax(request):
if request.method == 'POST':
file_obj = request.FILES.get('file')
import os
f = open(os.path.join(BASE_DIR, 'static', 'pic', file_obj.name), 'wb')
print(file_obj,type(file_obj))
for chunk in file_obj.chunks():
f.write(chunk)
f.close()
print('11111')
return HttpResponse('OK')
注意:
前台发送ajax请求时:
processData: false, // tell jquery not to process the data
contentType: false, // tell jquery not to set contentType
必须设置
方式三:
通过iframe标签提交
前段:
<div> <form id="my_form" name="form" action="/upload_iframe/" method="POST" enctype="multipart/form-data"> <input type="text" name="user"> <input type="password" name="password"> <input type="file" name="file"> <input type="button" value="upload" onclick="UploadFile()"> form> <iframe id='my_iframe' name='my_iframe' src="" class="hide">iframe> div>
JS:
function UploadFile() {
document.getElementById('my_iframe').onload = Testt;
document.getElementById('my_form').target = 'my_iframe';
document.getElementById('my_form').submit();
}
function Testt(ths){
var t = $("#my_iframe").contents().find("body").text();
console.log(t);
}
Django 后端:
def upload_iframe(request):
if request.method == 'POST':
print(request.POST.get('user', None))
print(request.POST.get('password', None))
file_obj = request.FILES.get('file')
import os
f = open(os.path.join(BASE_DIR, 'static', 'pic', file_obj.name), 'wb')
print(file_obj,type(file_obj))
for chunk in file_obj.chunks():
f.write(chunk)
f.close()
print('11111')
return HttpResponse('OK')
以上是文件上传的三种方式,在Tornado种也可以使用。
扩展:
在前段提交的时候 可以存在 checkbox 标签, 在Django中对于这种标签在后台获取值时用:
request.POST.getlist('favor', None) checkbox
其它
request.POST.get('favor', None) checkbox
