如何转换为response对象，然后提取中间的目标值？

Answer 1

Ini ialah JSON, ubah ia menjadi:

import json

content = '...你那堆东西'
result = json.loads(content)

print result['msg']

Ini akan menukar rentetan format JSON yang anda perolehi kepada kamus result dan kemudian memprosesnya seperti biasa.

Answer 2

Apa yang dikembalikan ialah data json, yang boleh dihuraikan terus menggunakan perpustakaan json python.
Saya rasa merangkak data json adalah yang paling menyeronokkan untuk diproses
Banyak data json yang saya rangkak baru-baru ini ialah data json yang dijana oleh permintaan seterusnya
