正在将所有dict值转换为str

Question

我有一个类方法将字典值转换为str，为将其作为post数据添加到formdata做准备，但是，有些值没有从int转换为str，例如：

jsonData={
"LanguageId":1,
"ClientTypeId":2,
"BrandId":3,
"JurisdictionId":1,
"ClientIntegratorId":1,
"ExternalIds":[10372246,10372249,10372236,10372239,10372234,10372235,10372231,10372233,10377244,10377245,10377254,10377247,10377251,10377248,10377249,10377246
],
"MarketCName":"win-draw-win",
"ScoreboardRequest":{
"ScoreboardType":3,
"IncidentRequest":{}
},
"BrowserId":2,
"OsId":4,
"ApplicationVersion":"",
"BrowserVersion":"15.4",
"OsVersion":"10.15.7",
"SessionId":'null',
"TerritoryId":227,
"CorrelationId":"71a5a843-a9cd-4152-9ef5-cede7ee59e33",
"VisitId":"b0d95dbe-fc0c-482a-a45c-1e300c8682b9",
"ViewName":"sports",
"JourneyId":"77057d08-5dff-4da4-afd7-087b97024194"
}

这是class:

class StringDict(dict):
def __init__(self):
dict.__init__(self)

def __getitem__(self, y):
value_to_string = str(dict.__getitem__(self, y))
return value_to_string

def get(self, y):
if isinstance(dict.get(self, y), list):
value_to_string = [str(x) for x in dict.get(self, y)]

elif isinstance(dict.get(self, y), dict):
value_to_string = {}
for keys, values in dict.get(self, y).items():
if isinstance(values, dict):
values_to_string[keys] = values
values_to_string[keys] = str(values)

elif isinstance(dict.get(self, y), int) or isinstance(dict.get(self, y), float):
value_to_string = str(dict.get(self, y))
else:
value_to_string = str(dict.get(self, y))
return value_to_string
exampleDict = StringDict()

测试：

for key, values in jsonData.items():
exampleDict[key] = values
[type(x) for x in {**exampleDict}.values()]
[int,
int,
int,
int,
int,
list,
str,
dict,
int,
int,
str,
str,
str,
str,
int,
str,
str,
str,
str]

我应该只有一个list, dict, str。其中list内部的所有值都是str，dict也是如此。

预期输出：

[str,
str,
str,
str,
str,
list,
str,
dict,
str,
str,
str,
str,
str,
str,
str,
str,
str,
str,
str]

list和dict中的所有值也应该是str。

Answer 1

您需要为values()添加一个__iter__方法来调用您的__getitem__:

def __iter__(self):
return dict.__iter__()

然后打印：

[<class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>, <class 'str'>]

Answer 2

您可以尝试简单的递归来转换dict:

def convert(o):
if isinstance(o, dict):
return {
k: convert(v) if isinstance(v, (list, dict)) else str(v)
for k, v in o.items()
}
elif isinstance(o, list):
return [
convert(v) if isinstance(v, (list, dict)) else str(v) for v in o
]

print(convert(jsonData))

打印：

"ClientTypeId": "2",
"BrandId": "3",
"JurisdictionId": "1",
