Python 讀寫文件 中文亂碼 錯誤TypeError: write() argument must be str, not bytes+

今天寫上傳文件代碼，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)

出現TypeError: write() argument must be str, not bytes錯誤

網上搜索才發現原來是文件打開方式有問題，把之前的打開語句修改為用二進制方式打開就沒有問題

改為：

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)

產生問題的原因是因為pickle存儲方式默認是二進制方式
