我有以下内容，希望将其解析为JSON。该类还具有item对象的列表
class Item(JSONEncoder):
def __init__(self):
self.Type = ''
self.Content = ''
self.N = None
self.Parent = None
self.Items = []
def reprJSON(self):
d = dict()
for a, v in self.__dict__.items():
if (hasattr(v, "reprJSON")):
d[a] = v.reprJSON()
else:
d[a] = v
return d
因此，当我尝试解析Item类的实例时，root.reprJSON()我得到以下结果。
{'Type': 'root',
'Content': '',
'N': 'root',
'Parent': None,
'Items': [<Item.Item at 0x10575fb3c88>,

但是我也想将那些项目的值也放到一个json对象中。我不知道该怎么做，将不胜感激。谢谢

下面的代码创建item类的实例，并用数据填充它。
def Crawl(parsedPDF):
soup = BeautifulSoup(parsedPDF, "html.parser")
root = Item()
root.Type = "root"
root.N = "root"
parent = root
head = root
body = RemoveEmptyTags(soup.body)
for tag in body:
elements = RemoveEmptyChild(tag.contents)
for element in elements:
if element.name == "head":
head = CreateHeading(root, parent, element)
parent = head.Parent
elif element.name == "p":
AddParagraph(head, element)
elif element.name == "figure":
pass
elif element.name == "figdesc":
pass
elif element.name == "table":
#elem = AddElement(head, element)
pass
else:
#elem = AddElement(head, element)
pass
pass
return root
def AddParagraph(head, element):
# split the paragraph into multiple lines based on alphabetize bullet points
lines = split_with_AplhabetizeBullets(element.text, '\.\s(\(.*?\)\s)')
for line in lines:
item = Item()
item.Content = line
item.Type = element.name
item.Parent = head
head.Items.append(item)
def CreateHeading(root, parent, element):
item = Item()
item.Content = element.text
item.Type = element.name
item.Parent = parent
try:
item.N = element["n"]
except:
pass
if item.N is None:
bracketTextLength = 0
try:
result = re.search(r'\(.*?\)',item.Content)
bracketTextLength = len(result.group)
except:
pass
item.N = item.Content
# to check if the heading without 'N' is a heading or its a subheading
if len(item.Content) > 3 and bracketTextLength == 0:
root.Items.append(item)
item.Parent = item
pass
else:
parent.Items.append(item)
pass
else: # item.N is not None
if parent.N is None:
item.Parent = item
parent = item.Parent
pass
#else: # if the new heading sharing the same reference as of its parent then
if parent.N in item.N[:len(parent.N)]:
parent.Items.append(item)
pass
else: # if the new heading has no parent then add it into root
root.Items.append(item)
item.Parent = item
pass
return item

查看您的代码，您可以在代码中使用此演示解决方案，因为我将Demo类的对象存储在Items列表中。您需要在Items类中编写[126, 88, 90, -19, -79, -35, 89, 115, -126, -49, 90, -86, -85, -6, 34, 29]
exception has occurred: OverflowError in
self.key = array.array('B',key).tobytes()
unsigned byte integer is less than minimum
和select orders.CustomerID, customers.ContactName , count(*)
from Orders
left join customers on Customers.CustomerID= Orders.customerid
group by Orders.customerid;
方法，并且还需要在serialize()方法中进行更改以在Items列表上进行迭代。
dumper()输出：
reprJSON
