我有一个带有<input type="file">
的表单,用于选择要上载的图像,单击了上载按钮后,将发送POST XMLHttpRequest,该调用调用upload_view
,该图像应将图像保存在服务器上。但是,由于某种原因,我的request.FILES
为空。当我console.log(document.getElementById('fileToUpload').files
时,我可以在那里看到文件。我的request.POST
看起来像这样:
<QueryDict: {'fileToUpload': ['[object FileList]'], 'csrfmiddlewaretoken': ['bOjUFzTnMVbHOWOQURj2egJuRizsVJIBMSfQra4yuz7MX3DOEaRPHbMVnY8xyIsU']}>
我的观点:
def upload_view(request):
key = f'{request.user}-{datetime.datetime.now().strftime("%Y%m%d%H%M%S")}'
for file in request.FILES.getlist('fileToUpload'):
TemporaryImage.objects.create(image=file, key=key)
return HttpResponse('complete')
我的JS:
function uploadFile() {
var fd = new FormData();
fd.append("fileToUpload", document.getElementById('fileToUpload').files);
var value = [];
document.getElementsByName('csrfmiddlewaretoken').forEach(function(x) {
value.push(x.value);
})
fd.append('csrfmiddlewaretoken', value[0]);
var xhr = new XMLHttpRequest();
xhr.open("POST", Urls['upload-view']());
xhr.send(fd);
}
我的表单:
<form id="form1" enctype="multipart/form-data" method="post">
{% csrf_token %}
<label for="fileToUpload">Select a File to Upload</label>
<input type="file" multiple="multiple" name="fileToUpload" id="fileToUpload">
<input type="button" onclick="uploadFile()" value="Upload">
</form>
答案 0 :(得分:2)
您需要分别附加每个文件。
var fd = new FormData();
var files = document.getElementById('fileToUpload').files;
for (var x=0; x < files.length; x++) {
fd.append("fileToUpload", files[x]);
}
