How to Unirest HTTP API Requests Call in Java

Unirest is a set of lightweight HTTP libraries available in multiple languages, built and maintained by Mashape, who also maintain the open-source API Gateway Kong.

Do yourself a favor, and start making HTTP requests like this:

Creating Function :

    /**
     * Unirest API call return jsonResponse handle
     * Function Name: ApiCallFunction
     * @param vEmail, Url
     * @return status
     */
    public static String ApiCallFunction(String vEmail, String Url) {
        try{
            HttpResponse<JsonNode> jsonResponse = Unirest.post(Url)
            .field("vEmail",vEmail)
            .asJson();
            JSONObject output= jsonResponse.getBody().getObject();
   String status= output.getString("status");
            return status;
        }catch(UnirestException e){
           return "error";
        }
        
    }

Type Of  Response Handle:

// Response to String
Sting bookResponse = Unirest.get(Url).asString();

//Response Basic Authentication
HttpResponse<JsonNode> jsonResponse = Unirest.get(Url).basicAuth("username", "password").asJson();
JSONObject output= jsonResponse.getBody().getObject();

//Response Object to Json
HttpResponse<JsonNode> jsonResponse = Unirest.post(Url)
        .header("accept", "application/json")
        .header("Content-Type", "application/json")
        .body(authorObject)
        .asJson();
JSONObject output= jsonResponse.getBody().getObject();
  
// Response to Object
HttpResponse<Book> bookResponse = Unirest.get(Url).asObject(Book.class);
Book bookObject = bookResponse.getBody();

// Response to Author
HttpResponse<Author> authorResponse = Unirest.get(Url)
    .routeParam("id", bookObject.getId())
    .asObject(Author.class);

Author authorObject = authorResponse.getBody();

Response :
Upon recieving a response Unirest returns the result in the form of an Object, this object should always have the same keys for each language regarding to the response details.

• getStatus() - HTTP Response Status Code (Example: 200)
• getStatusText() - HTTP Response Status Text (Example: "OK")
• getHeaders() - HTTP Response Headers
• getBody() - Parsed response body where applicable, for example JSON responses are parsed to Objects / Associative Arrays.
• getRawBody() - Un-parsed response body
