Question

我有以下数据字符串：

{"responseStatus":"ok","responseHeader":{"now":1528734419187,"status":"ok","requestId":"Wx6i0wquZS4AAFNeStwAAABg"},"responseData":{"id":38}}

我需要从中取出＆＃34; id＆＃34;：38并将其格式化为＆＃34; id＆＃34;：＆＃34; 38＆＃34;

Answer 1

由于您使用的是requests库（基于您的代码），因此在调用您的repsonse时，您可以返回.content而不是返回.json()：

response = requests.get(....).json()
response['responseData']['id'] = str(response['responseData']['id'])   # or you can just do "38"

Answer 2

您可以使用json模块：

import json
json_s = json.loads('{"responseStatus":"ok","responseHeader":{"now":1528734419187,"status":"ok","requestId":"Wx6i0wquZS4AAFNeStwAAABg"},"responseData":{"id":38}}')

json_s['responseData']['id'] = '38' # Or str(json_s['responseData']['id'])


print(json_s)

或者在这种情况下，它是一个有效的字典，因此您可以使用eval()：

json_s = '{"responseStatus":"ok","responseHeader":{"now":1528734419187,"status":"ok","requestId":"Wx6i0wquZS4AAFNeStwAAABg"},"responseData":{"id":38}}'

a = eval(json_s)

a['responseData']['id'] = '38' # Or str(a['responseData']['id'])

print(a)

如果您想将json_s和a中的字典转换回字符串，则只需分别使用str(json_s)和str(a)。

有关eval()的使用，请参阅the documentation。

否则，请远离eval()使用ast模块。如下所述：
