I'm trying to write a JSON-based web API in a Sinatra app. I want to POST a JSON object as the post body (with the proper content-type set) but I'm struggling.
In Cocoa, I'd do something like
[mutableHTTPRequest setHTTPBody:dataRepresentationOfJSONObject];
And the content type, set to JSON, would then post the HTTP body as a JSON object. I'm trying to do this with jquery. The best I can do so far just takes the JSON object and turns it into a normal style key=value&…
style post body, and that's not what I'm after.
My Javascript:
var data = { "user" : "me!" };
$.ajax({
type: "POST",
url: "/api/user/create",
contentType: 'application/json',
data: data,
success: function(r) {
});
Any pointers on how to do this? My goal is for my Sinatra to do like the following
post "/api/user/create" do
js = JSON.parse(request.body.read)
# do something with the js object… this works when POSTing from Cocoa
end
Add the processData parameter to your ajax request and set it to false. Additionally, you need to stringify your object to turn it into JSON.
var data = { "user" : "me!" };
$.ajax({
type: "POST",
url: "/api/user/create",
processData: false,
contentType: 'application/json',
data: JSON.stringify(data),
success: function(r) {
}
});
JSON.stringify
will not work in older versions of IE unless you implement it. http://json.org
