从另一个Dataframe的列中的JSON URL生成数据帧

import pandas as pd
import requests
import json

df_new = pd.DataFrame()

for index, row in df.iterrows():
    json_url = row['JSON_URL']
    response = requests.get(json_url)
    data = response.json()

df_temp = pd.DataFrame(data)
df_new = df_new.append(df_temp, ignore_index=True)
