python-3.x - 在python3中操作类型字节

问题描述

你能帮我从这个字节中获取报告的ID吗？

b'{
"message":"The report with id 9520 was created but it is invalid!", 
"violations":"{\\"schemaLocation\\":\\"#\\",\\"pointerToViolation\\":\\"#\\",\\"causingExceptions\\":[{\\"schemaLocation\\":\\"#\\",\\"pointerToViolation\\":\\"#\\",\\"causingExceptions\\":[],\\"keyword\\":\\"required\\",\\"message\\":\\"required key [reportType] not found\\"},{\\"schemaLocation\\":\\"#\\",\\"pointerToViolation\\":\\"#\\",\\"causingExceptions\\":[],\\"keyword\\":\\"required\\",\\"message\\":\\"required key [finishedAt] not found\\"},{\\"schemaLocation\\":\\"#/properties/hosts/items\\",\\"pointerToViolation\\":\\"#/hosts/0\\",\\"causingExceptions\\":[],\\"keyword\\":\\"required\\",\\"message\\":\\"required key [applications] not found\\"}],\\"message\\":\\"3 schema violations found\\"}",    
"valid":false
}'

解决方案

您还没有清楚地提到所有可能的输入。但是，对于给定的输入，下面的程序将起作用！这有点硬编码！

import json

data=b'{"message":"The report with id 9520 was created but it is invalid!", "violations":"{\\"schemaLocation\\":\\"#\\",\\"pointerToViolation\\":\\"#\\",\\"causingExceptions\\":[{\\"schemaLocation\\":\\"#\\",\\"pointerToViolation\\":\\"#\\",\\"causingExceptions\\":[],\\"keyword\\":\\"required\\",\\"message\\":\\"required key [reportType] not found\\"},{\\"schemaLocation\\":\\"#\\",\\"pointerToViolation\\":\\"#\\",\\"causingExceptions\\":[],\\"keyword\\":\\"required\\",\\"message\\":\\"required key [finishedAt] not found\\"},{\\"schemaLocation\\":\\"#/properties/hosts/items\\",\\"pointerToViolation\\":\\"#/hosts/0\\",\\"causingExceptions\\":[],\\"keyword\\":\\"required\\",\\"message\\":\\"required key [applications] not found\\"}],\\"message\\":\\"3 schema violations found\\"}","valid":false}'


data = json.loads(data)["message"].split()

data是一个包含message键值的列表！您可以对其进行索引以获得所需的值！

>>> data
['The', 'report', 'with', 'id', '9520', 'was', 'created', 'but', 'it', 'is', 'invalid!']
