'unexpected EOF while parsing'报错，求助我错在那里！？

Question

下面是我用python写的小爬虫，报错错误出在eval()附近，但是我找了一下午都没有找到错误在那里！！跪求大神们帮助。
下面是我的代码

import requests
import time
import urllib3
import requests
from urllib.parse import urlencode

content=[]
relation=[]
eventlist=[]##所有event记录
texts=[]
texts.append('货币超发')##event会不断的加content到text里，当遍历了所有content没有新的content加进来了，程序就会自动停止

headers = {
    'Host':'eeg.8wss.com',
    'Referer':'http://eeg.8wss.com/main',
    'User_Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.79 Safari/537.36 Maxthon/5.2.7.5000',
    'X-Requested-With':'XMLHttpRequest',
    }

params = {
        'text':texts,
        'layers':1
        }

base_url='http://eeg.8wss.com/api/query_abstract_event?'

def get_page(text):
    url = base_url + urlencode(params)
    try:
        time.sleep(5)
        #response=requests.get(url,headers=headers)
        http=urllib3.PoolManager()
        response=http.request('GET',url)
        htmll=response.data.decode('UTF-8')
        html=eval(htmll)
        return html
    except requests.ConnectionError as e:
        print('Error', e.args)
        time.sleep(300)
        get_page(text)


def parse_page(html):
    relations=html.get('relations')
    event=html.get('events')

    if relations:##当当前节点不能再展开时，返回的response为空
        for i in relations: 
            if len(i)==9 and i['code'] not in content:
                content.append(i)
            if len(i)==4 and i['code'] not in relation:
                relation.append(i)
            else:
                continue
    if event:
        for j in event:
            if j['code'] not in eventlist:
                eventlist.append(j)
                if j['category']=='abstract':##abstract为蓝色的可衍生节点
                    texts.append(j['text'])
            else:
                continue



if __name__=='__main__':
    #for text in texts:
    haha = get_page(text)
    results=parse_page(haha)

报错：
File "", line 36, in get_page
html=eval(htmll)

File "", line unknown

^

SyntaxError: unexpected EOF while parsing

Answer 1

html=eval(htmll) 这一行的htmll变量是空值，至于为什么你要仔细debug了
