Golang : Query string with space symbol %20 in between

Problem :

You want to form URL that looks like this :

 https://example.com/query?keyword="golang lookup"

but your final URL looks like this :

 https://example.com/query?keyword="golang%20lookup"

How to get rid the %20 sign ?

Solution :

Use url.QueryEscape() function to escapes the string so it can be safely placed inside a URL query. For example :

 func TagSearch(tag string) string {
 return fmt.Sprintf("https://example.com/query?keyword=%s", url.QueryEscape(tag))
 }
