今天写上传文件代码，如下
def uploadHandle(request):
pic1=request.FILES['pic1']
picName=os.path.join(settings.MEDIA_ROOT,pic1.name)
with open(picName,'w') as pic:
for c in pic1.chunks():
pic.write(c)
return HttpResponse(picName)
出现TypeError: write() argument must be str, not bytes错误
网上搜索才发现原来是文件打开方式有问题，把之前的打开语句修改为用二进制方式打开就没有问题
改为：
def uploadHandle(request):
pic1=request.FILES['pic1']
picName=os.path.join(settings.MEDIA_ROOT,pic1.name)
with open(picName,'wb+') as pic:
for c in pic1.chunks():
pic.write(c)
return HttpResponse(picName)
产生问题的原因是因为pickle存储方式默认是二进制方式
