编码

urllib库里面有个urlencode函数，可以把key-value这样的键值对转换成我们想要的格式，返回的是a=1&b=2这样的字符串，比如：

import urllib.parse

url = 'https://market.m.taobao.com/apps/market/content/index.html?contentId=210495552952&spm=a2141.7631544.t1.p602&scm=1007.11419.126969.0&wh_weex=true&wx_navbar_transparent=true&business_spm=a2141.12288619&source=youhh_tuji&params={"yhhListContentId":"210495552952"}&utparam={"x_object_type":"content_item","x_item_ids":569376571773,"x_object_id":"210495552952"}'


params = {
    "yhhListContentId":"210495552952",

}
utparam = {
    "x_object_type":"content_item",
    "x_item_ids":569376571773,
    "x_object_id":"210495552952"
}

params = urllib.parse.urlencode(params)
utparam = urllib.parse.urlencode(utparam)

url1 = 'https://market.m.taobao.com/apps/market/content/index.html?contentId=210495552952&spm=a2141.7631544.t1.p602&scm=1007.11419.126969.0&wh_weex=true&wx_navbar_transparent=true&business_spm=a2141.12288619&source=youhh_tuji' + "&" + params + '&' + utparam

print(url1)
