Answer 2

感谢您的回复！
我试了一下，还是报同样的错误.

import json
import requests
import time

def asas(url):

headers = {
    "Content-Type": "text/plain; charset=utf-8",
    'Referer': 'http://zjt.shandong.gov.cn/xyzj/DTFront/ZongHeSearch/Detail_Company.aspx?ProjectNum=370999201902130102&CertNO=0&searchType=2',
    "User-Agent": "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36",
}

wor={
     'methodname':'GetProjectInfo',
     'ProjectNum':'370999201902130102',
     'ProjectName':'',
     'CityCode':'',
     'ProjectType':'',
     'BuildCorp':'',
     'ConsCorp':'',
     'Constructop':'',
     'Supervision':'',
     'CurrPageIndex':1,
     'PageSize':1,
     'TopNum':1,
     '-':'1560732472155',
     }
comments = requests.get(url,data=wor,headers=headers)
jd = json.loads(comments.text) 


print(jd)


   

if name == '__main__':

urls='http://221.214.94.41:81/InformationReleasing/Ashx/InformationReleasing.ashx?callback=jQuery17107411760366652407_1560732471975'
url= asas(urls)  



运行后：JSONDecodeError       Traceback (most recent call last)
Expecting value: line 1 column 1 (char 0)
