在用python进行上交所爬虫时遇到这样的问题，请问需要怎么解决

Question

以下是代码：

import json
import requests
import re
import datetime
import csv 
import time
f=open('C:\\Users\\liu\\Desktop\\python\\年报爬取\\连续天数'+'stkcd.csv',mode='w',encoding='gbk',newline='')

head=['stkcd']
writer.writerow(head)

    time.sleep(1)

        ,
        headers={'Referer':'http://www.sse.com.cn/disclosure/listedinfo/announcement/'}
    )
    json_str1 = responsel.text[19:-1]
    data1=json.loads(json_str1)
    max_page=data1['pageHelp']['pageCount']+1
    for j in range(1,max_page):

        for report in data['result']:
            download_url='http://www.sse.com.cn/'+report['URL']
            if re.search('年度报告',report['TITLE'],re.S):

                    print(filename)
                    writer.writerow([report['SECURITY_CODE']])

                        resource=requests.get(download_url,stream=True)
                        with open('C:\\Users\\liu\\Desktop\\python\\年报爬取\\连续天数'+filename,'wb') as fd:
                            for y in resource.iter_content(102400):
                                fd.write(y)
                            print(filename,'完成下载')
                    else: 
                        download_url='http://www.sse.com.cn/'+report['URL']

                                fd.write(y)
                            print(filename,'完成下载')
f.close()              

以下是运行后报错的内容：

检查代码中第30行json_str，存在json无法解析的数据，参考一下json.loads的数据结构类似于：jsonData = '{"a":1,"b":2,"c":3,"d":4,"e":5}'
