参数里面的变量该如何写呢?
# 获取毫秒级时间戳,用于网页验证def getTime():
return int(round(time.time() * 1000))
code_list=["110000", "120000","130000", "140000", "150000","210000"]
for code in code_list:
key={}
key['m']='QueryData'
key['dbcode']='fsnd'
key['rowcode']='zb'
key['colcode']='sj'
key['wds']='[{"wdcode":"reg","valuecode":"110000"}]'
key['dfwds']='[{"wdcode":"sj","valuecode":"LAST20"}]'
key['k1']=str(getTime())
我希望用code来代替"110000",如何写呢? 本帖最后由 tianyagd 于 2023-11-14 12:42 编辑
parameters={
'm':'QueryData',
'dbcode':'fsnd',
'rowcode':'reg',
'colcode':'sj',
'wds':'[{"wdcode":"zb","valuecode":"A020101"}]',
'dfwds':'[{"wdcode":"sj","valuecode":"LAST20"}]',
'k1':'1699793930478 '
}
这样的参数形式,如果用变量zb来替代 "A020101",又如何写呢?谢谢! def getTime():
return int(round(time.time() * 1000))
code_list = ["110000", "120000", "130000", "140000", "150000", "210000"]
for code in code_list:
key = {}
key['m'] = 'QueryData'
key['dbcode'] = 'fsnd'
key['rowcode'] = 'zb'
key['colcode'] = 'sj'
key['wds'] = f'[{"wdcode":"reg","valuecode":"{code}"}]'
key['dfwds'] = '[{"wdcode":"sj","valuecode":"LAST20"}]'
key['k1'] = str(getTime()) def getTime():
return int(round(time.time() * 1000))
code_list = ["110000", "120000", "130000", "140000", "150000", "210000"]
for code in code_list:
key = {}
key['m'] = 'QueryData'
key['dbcode'] = 'fsnd'
key['rowcode'] = 'zb'
key['colcode'] = 'sj'
key['wds'] = '[{"wdcode":"reg","valuecode":"' + code + '"}"}]'
key['dfwds'] = '[{"wdcode":"sj","valuecode":"LAST20"}]'
key['k1'] = str(getTime()) 以上我发的两种方式都可以,其他的类推就行,不难 头脑发热的少年 发表于 2023-11-14 12:45

不用变量时,可以正常爬到数据。按照你的方法,错误提示如上 本帖最后由 superTian 于 2023-11-14 13:51 编辑

那你就用我的第二种方法,那个方法是肯定可以的,你可以在语句之前打个print,输出一下code,是不是跟你之前的值是一样的 头脑发热的少年 发表于 2023-11-14 12:46

原来是多了半边花括号
