如何使用Python从相同的id中提取多个字符串

I wrote this bit of code in order to extract the id's and roll's from a website.

我写了这段代码，以便从网站中提取id和roll。

import requests
import json
import time
import urllib


def ColorRequest(a=True):
url = 'http://csgoroll.com/v1/roulette/state?token=bcb7841fe779ac0ae2a9e4f882ed3961ce0d714215fede3c025a24fc418e123dcb5a0a47a0ba1825225c14b39e08ea399422eb2b012689a79c41f42b529640e37d5374125c3fef409b2d165c223923dbc27f320c53bf10e46e701058251c97b9'  # Could add a + pls str(pagesomething) to add on to the url so that it would update
sourcecode = requests.get(url)  # requests the data from the site
plaintext = sourcecode.text  # imports all of the data gathered

obj = json.loads(plaintext)
for roll in obj['rolls']:

    print(roll['id'], roll['roll'])
    while a == True:
        ColorRequest()
        time.sleep(1000)


if __name__ == '__main__':
ColorRequest()

But the data looks like this

但数据看起来像这样

{
"gameState": 
"1",
"currentGame": "9965464",
"startDate": "Mon Dec 05 2016 23:30:42 GMT+0000 (UTC)",
"rolls": [
    {
        "id": 9965465,
        "hash": "f39a2391bd589fc217b73c407e316ff440dc920657929bd7ca9b7adddf0cedc9",
        "roll": 11,
        "state": 3,
        "created_at": null,
        "updated_at": null
    },
    {
        "id": 9965466,
        "hash": "45eaa2bddb3281f036932de5839d4ccc2b28ebb1d4ded8f6e67cbff273831c73",
        "roll": 3,
        "state": 3,
        "created_at": null,
        "updated_at": null
    },
    {
        "id": 9965467,
        "hash": "b6142c643816d2913a29518fdf624fcf577397af4ebfb008d61c4f1cf9d6ba3e",
        "roll": 1,
        "state": 3,
        "created_at": null,
        "updated_at": null
    },

My question is how do I get my program to recognize that there is multiple layers of data for it to read and store it, so far it will only grab the top result and contain it at run time.

我的问题是如何让我的程序识别出有多层数据供它读取和存储，到目前为止它只会获取最高结果并在运行时包含它。

2 个解决方案

#1

Check the len(rolls) to make sure is at least 1 and then just set the value of the 1st element for example top_id = obj['rolls'][0]['id'] or top_state = obj['rolls'][0]['state'] hope that helps.

检查len（roll）以确保至少为1，然后设置第一个元素的值，例如top_id = obj ['rolls'] [0] ['id']或top_state = obj ['rolls'] [0] ['州']希望有所帮助。

#2

If I understand it right, all you want to do is repeat the loop every 1000 seconds, and at each iteration print all data in the rolls.

如果我理解正确，你想要做的就是每1000秒重复一次循环，并在每次迭代时打印卷中的所有数据。

import requests
import time

def ColorRequest():
    url = 'http://csgoroll.com/v1/roulette/state?token=bcb7841fe779ac0ae2a9e4f882ed3961ce0d714215fede3c025a24fc418e123dcb5a0a47a0ba1825225c14b39e08ea399422eb2b012689a79c41f42b529640e37d5374125c3fef409b2d165c223923dbc27f320c53bf10e46e701058251c97b9'  # Could add a + pls str(pagesomething) to add on to the url so that it would update
    sourcecode = requests.get(url)  # requests the data from the site
    obj = sourcecode.json()
    for roll in obj['rolls']:
        print(roll['id'], roll['roll'])

if __name__ == '__main__':
    while True:
        ColorRequest()
        time.sleep(1000)   # these are seconds, ~17min
