How to stop NodeJS “Request” module changes request when using proxy

阅读更多关于 How to stop NodeJS “Request” module changes request when using proxy

问题 Sorry if this comes off as confusing. I have written a script using the NodeJS request module that runs and performs a function on a website then returns with the data. This script works perfectly fine when I do not use a proxy by setting it to false. This is not a task that is NOT allowed to be done with Selenium/puppeteer proxy: false However, when I set a (working) proxy.

Any ideas how to do this or other ways that solve

Here is what I mean: I want to wrap a simple array in a Proxy object. I want a 'set' handler to run when I wish to push() a new value to this Proxy object. The trouble is that proxy handlers like 'set' get called multiple times for one operation to an array. In some cases it seems fairly easy to deal with the problem but in other cases one
