Question

我有一个包含原始数据的文本文件。我想解析这些数据并清理它以便可以进一步使用。以下是rawdata。

"{\x0A    \x22identifier\x22: {\x0A        \x22company_code\x22: \x22TSC\x22,\x0A        \x22product_type\x22: \x22airtime-ctg\x22,\x0A        \x22host_type\x22: \x22android\x22\x0A    },\x0A    \x22id\x22: {\x0A        \x22type\x22: \x22guest\x22,\x0A        \x22group\x22: \x22guest\x22,\x0A        \x22uuid\x22: \x221a0d4d6e-0c00-11e7-a16f-0242ac110002\x22,\x0A        \x22device_id\x22: \x22423e49efa4b8b013\x22\x0A    },\x0A    \x22stats\x22: [\x0A        {\x0A            \x22timestamp\x22: \x222017-03-22T03:21:11+0000\x22,\x0A            \x22software_id\x22: \x22A-ACTG\x22,\x0A            \x22action_id\x22: \x22open_app\x22,\x0A            \x22values\x22: {\x0A                \x22device_id\x22: \x22423e49efa4b8b013\x22,\x0A                \x22language\x22: \x22en\x22\x0A            }\x0A        }\x0A    ]\x0A}"

我想删除所有十六进制字符，我尝试解析数据并存储在数组中并使用re.sub（）清除它，但它提供了相同的数据。

for line in f:
    new_data = re.sub(r'[^\x00-\x7f],\x22',r'', line)
    data.append(new_data)

\ x0A是换行符的十六进制代码。在process_request()之后，AuthenticationMiddleware会给出

您应该使用$URL="C://<path to html file>/A.html";模块header('Location: testApp/A.html');（来自文件）或s = <your json string>（来自字符串）函数解析此问题。你会得到一个带有2个词组的词典和带有词典的列表。

在Python中解析和清理文本文件？
