Keeping Query Params in a Hashtable

Demonstrates how to use a Chilkat Hashtable to hold query params and re-emit as a query param string.

Note: The ToQueryString method was added in Chilkat v9.5.0.92.

Go

    success := false

    ht := chilkat.NewHashtable()

    // Add name/value pairs from an existing query param string where the values are already URL encoded.
    var qp *string = new(string)
    *qp = "txt=this%20is%20a%20test&color=blue&fruits=apples%26oranges"
    success = ht.AddQueryParams(*qp)

    // Add some additional name/value pairs.
    ht.AddStr("name","Jack Sparrow")
    ht.AddStr("movie","Pirates of the Carribean")

    // Iterate over the hash table to show what we have..

    keys := chilkat.NewStringTable()
    ht.GetKeys(keys)
    numKeys := keys.Count()
    var key *string = new(string)
    var val *string = new(string)
    i := 0
    for i < numKeys {
        key = keys.StringAt(i)
        val = ht.LookupStr(*key)
        fmt.Println(*key, " = ", *val)
        i = i + 1
    }

    // Output for the above loop:

    // color = blue
    // name = Jack Sparrow
    // fruits = apples&oranges
    // txt = this is a test
    // movie = Pirates of the Carribean

    // Get all name/value pairs as a query parm string with values URL encoded
    qp = ht.ToQueryString()
    fmt.Println(*qp)

    // Result:
    // color=blue&name=Jack%20Sparrow&fruits=apples%26oranges&txt=this%20is%20a%20test&movie=Pirates%20of%20the%20Carribean

    ht.DisposeHashtable()
    keys.DisposeStringTable()
