GET/POST参数的数量超出了设置.DATA_UPLOAD_MAX_NUMBER_FIELD S.

Question

我收到一个错误,GET/POST参数的数量超出了设置.DATA_UPLOAD_MAX_NUMBER_FIELDS.Error在/ api/upload上说TooManyFieldsSent GET/POST参数的数量超出了settings.DATA_UPLOAD_MAX_NUMBER_FIELDS.我在views.py中写道

def upload(request):
    id, array = common(request)

    if request.FILES:
        file = request.FILES['req'].temporary_file_path()
    else:
        return HttpResponse('<h1>NG</h1>')

    return HttpResponse('<h1>OK</h1>')

def common(request):
    id = json_body.get("access", "0")
    if id == "":
        id = "0"

    s = []
    with open(ID_TXT, 'r') as f:
        for line in f:
            s += list(map(int, line.rstrip().split(',')[:-1]))

    array = [s[i:i + 2] for i in range(0, len(s), 2)]

    return id, array

我使用POSTMAN发布访问和req数据

我认为这个错误是能够发送文件大小的限制,所以我在settings.py中添加了一个代码

DATA_UPLOAD_MAX_MEMORY_SIZE = 100000000

但错误无法解决.我读了这个页面如何避免"超出GET/POST参数的数量"错误？作为参考.我该如何解决这个问题？

Answer 1

正如django的doc所说,DATA_UPLOAD_MAX_NUMBER_FIELDS的值是默认的1000,所以一旦你的表单包含的字段多于那个数字,你就会得到TooManyFields错误.

点击这里:https://docs.djangoproject.com/en/1.11/ref/settings/

所以解决方案很简单我认为,如果您的settings.py存在DATA_UPLOAD_MAX_NUMBER_FIELDS,则将其值更改为更高的值,或者如果不存在,则将其添加到settings.py:

DATA_UPLOAD_MAX_NUMBER_FIELDS = 10240 # higher than the count of fields

Answer 2

当我尝试向后端发布一个巨大的列表值时发生了这种情况。在我的情况下，我可以自由地将列表作为字符串发送，并且它起作用了。Django 默认有这个检查来防止可疑活动（SuspiciousOperation）。

但是，以下设置也将起作用。

# to disable the check
DATA_UPLOAD_MAX_NUMBER_FIELDS = None

You can set this to None to disable the check. Applications that are expected to receive an unusually large number of form fields should tune this setting.来自 Django 官方文档。https://docs.djangoproject.com/en/3.1/ref/settings/#data-upload-max-number-fields
