How to pass key value pairs via a URL?
Answer:
At the minute I use ¶m2=key|value,key|value. I separate the key from the value using a vertical line, and the pairing with a comma, everything after the equals is encoded using encodeURIComponent(). This works fine.
However, the user has control of the value... And as sensible human beings we all know that the first thing the user will probably do is stick a vertical bar or a comma as one of the values breaking my parameter parser. Is there a better way to do this? I've seen PHP users talking about storing associated arrays in urls but I'm looking for a pure javascript solution.

Write a function named "query_dict" that a key-value store as a parameter mapping strings to floating point numbers. The function will make an HTTPS GET request to the url "https://fury.cse.buffalo.edu/ps-api/a" with a query string containing the same key-value pairs from the input key-value store. The response from the server will be a JSON string representing an object in the format "{"answer": <Number>}" where <Number> is a floating point Number. Return the value at the key "answer" as a float Recall...
