Manually formatting the query string is fine for simple situations. But it can become tedious when there are many parameters.
You could write a simple utility function that handles building the query formatting for you.
function formatParams( params ){
return "?" + Object
.keys(params)
.map(function(key){
return key+"="+encodeURIComponent(params[key])
})
.join("&")
}
And you would use it this way to build a request.
var endpoint = "https://api.example.com/endpoint"
var params = {
a: 1,
b: 2,
c: 3
}
var url = endpoint + formatParams(params)
//=> "https://api.example.com/endpoint?a=1&b=2&c=3"
There are many utility functions available for manipulating URL's. If you have JQuery in your project you could give http://api.jquery.com/jquery.param/ a try.
It is similar to the above example function, but handles recursively serializing nested objects and arrays.
"blahblah.php?variable1=" + var1 + "&variable2=" + var2
var1
andvar2
do not themselves contain reserved characters. You may want to escape them withencodeURIComponent()
