我该如何转换这个字符串，使其内部只包含dict对象？
例如：

{
"correlation_id": "asdfsdf-dsfasdfa-adfadsf-asdf",
"invocation_timestamp": null,
"invoked_component": "lambda",
"invoker_agent": null,
"message": {
"errorMessage": "Unauthorized",
"statusCode": 401
},
"message_type": "ERROR",
"original_source_app": "",
"response_timestamp": "2020-10-01 04:46:37.121436",
"status": 401,
"target_idp_application": "",
"timezone": "UTC"
}

你可以这样做得到字符串形式

test = '''[ERROR] 2020-10-01T04:46:37.sdfsdqs889dgsdg9dgdf {
"correlation_id": "asdfsdf-dsfasdfa-adfadsf-asdf",
"invocation_timestamp": null,
"invoked_component": "lambda",
"invoker_agent": null,
"message": {
"errorMessage": "Unauthorized",
"statusCode": 401
},
"message_type": "ERROR",
"original_source_app": "",
"response_timestamp": "2020-10-01 04:46:37.121436",
"status": 401,
"target_idp_application": "",
"timezone": "UTC"
}'''

print(test[test.find('{'):]) # find the first '{' and discard all characters before that index in the string

如果你想把它作为一个dict对象

import json
dict_form = json.loads(test[test.find('{'):]) # same as before now sending it to json.loads which converts a string to a dict object (as most requests are sent as a string)
print(dict_form)

试试看
res = json.loads（字符串变量）打印（res）
现在您可以使用resdict来访问它。
