参数里面的变量该如何写呢？

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？

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！

以上我发的两种方式都可以，其他的类推就行，不难

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

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
