Fetching External Web Pages and Making HTTP Calls

Stallion bundles in the third party library Unirest in order to make HTTP calls.

var Unirest = Java.type('com.mashape.unirest.http.Unirest'); // Get an HTML web page var response = Unirest.get("http://httpbin.org/html").asString(); var html = response.getBody(); assert 200 === response.getStatus(); assert html.indexOf("Herman Melville" > -1); // Get a JSON web page var response = Unirest.get("http://httpbin.org/get").asJson(); var obj = response.getBody(); // Get a JSON web page as a javascript dictionary var response = Unirest.get("http://httpbin.org/get").asString(); var data = stallion.JSON.parseMap(response.getBody()); assert "http://httpbin.org/get" === data.url // POST JSON var result = Unirest.post("http://httpbin.org/post") .queryString("name", "Mark") .field("last", "Polo") .asJson() var jsonNode = result.getBody(); assert "Polo".equals(jsonNode.getObject().get("last")); import com.mashape.unirest.http.Unirest; import com.mashape.unirest.http.HttpResponse; HttpResponse<String> httpResponse = Unirest.get("http://httpbin.org/html") .asString(); assert httpResponse.getStatus() == 200; assert httpResponse.getBody().contains("Moby Dick"); // To JSON Object HttpResponse<String> bookResponse = Unirest.get("http://httpbin.org/books/1").asString(); Book book = JSON.parse(bookResponse.getBody(), Book.class); // POST JSON HttpResponse<JsonNode> jsonResponse = Unirest.post("http://httpbin.org/post") .queryString("name", "Mark") .field("last", "Polo") .asJson(); assert "Polo".equals(jsonResponse.getBody().getObject().get("last"));
