Question

我正在尝试获得有效载荷值＆＃34; productid＆＃34;到+1。但是当我使用productid + 1时，productid变量不会改变？

当我运行脚本时，产品ID保持为＆＃34; 7367＆＃34;何时应该更改为＆＃34; 7368＆＃34;

productid=7367

headers = {
    "Host": "www..co.uk",
    "Connection": "keep-alive",
    "Content-Length": "121",
    "Cache-Control": "max-age=0",
    "Origin": "http://www..co.uk",
    "Upgrade-Insecure-Requests": "1",
    "User-Agent": "Chrome/57.0.2987.133 Safari/537.36",
    "Content-Type": "application/x-www-form-urlencoded",
    "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
    "Accept-Encoding": "gzip, deflate, br",
    "Accept-Language": "en-US,en;q=0.8",
    }

payload = {
    "attributes":"",
    "product_quantity":"1",
    "submit":"",
    "product_id":productid+1,
    "show_image_":"0",

}

print ("ProductID:"), productid

Answer 1

"product_id":productid+1,

只是递增当前值并将其分配给有效负载字典而不是返回到productid变量。所以在你拥有这个

的页面的下方

print ("ProductID:"), productid

您只是将原始值打印为您没有保存到该变量的增量。

要做到这一点，您需要在脚本底部打印有效负载product_id变量，或者递增并保存回变量，如下所示

productid += 1

payload = {
    "attributes":"",
    "product_quantity":"1",
    "submit":"",
    "product_id":productid,
    "show_image_":"0",

}

print ("ProductID:"), productid

为什么我的变量放在有效载荷中时不会改变？
