View source for WebDev: Usando diversos comandos e linguagens para buscar conteúdo via HTTP

= Dica =

Use o plugin Postman do Google Chrome para gerar trechos de código na sua linguagem preferida!!!

[[Ficheiro:PostMan01.jpg]]

= Exemplos =

==cURL==

 <nowiki>curl -X POST -d "fizz=buzz" http://httpbin.org/ip</nowiki>

==Python (with Requests)==

 <nowiki>
 import requests, time
 r = requests.post('http://httpbin.org/ip', data={"ts":time.time()})
 print r.status_code
 print r.content
 </nowiki>

==Node.js (with request)==

 <nowiki>
 var request = require('request');
 var url ='http://httpbin.org/ip'
 request(url, function (error, response, body) {
   if (!error) {
     console.log(body);
   }
 });
 </nowiki>

==Perl==

 <nowiki>
 use LWP::Simple;
 $contents = get("http://httpbin.org/ip");
 </nowiki>

==Java (Apache Commons)==

Importante: Apache Commons foi substituído pelo Apache HttpComponents e seus módulos [https://hc.apache.org/httpcomponents-client-ga/ HttpClient] e HttpCore.

 <nowiki> 
 import org.apache.commons.httpclient.*;
 import org.apache.commons.httpclient.methods.*;
 import org.apache.commons.httpclient.params.HttpMethodParams;
 
 import java.io.*;
 
 public class JavaHttpClientExample {
   public static void main(String[] args) {
     HttpClient client = new HttpClient();
     GetMethod method = new GetMethod("http://httpbin.org/ip");
     try {
       int statusCode = client.executeMethod(method);
       byte[] responseBody = method.getResponseBody();
       System.out.println(new String(responseBody));
     } catch (Exception e) {
       System.err.println("Fatal error: " + e.getMessage());
       e.printStackTrace();
     } finally {
       method.releaseConnection();
     }
   }
 }
 </nowiki>

==PHP==

 <nowiki>
 <?php
     $result = file_get_contents('http://httpbin.org/ip');
     echo $result;
 ?>
 </nowiki>


==C# / .NET (4.5+)==

 <nowiki>
 using System;
 using System.Net.Http;
 using System.Threading.Tasks;
 
 namespace NetHttpClientExample
 {
   class Program
   {
     static void Main(string[] args)
     {
       var task = MakeRequest();
       task.Wait();
 
       var response = task.Result;
       var body = response.Content.ReadAsStringAsync().Result;
       Console.WriteLine(body);
     }
 
     private static async Task<HttpResponseMessage> MakeRequest()
     {
       var httpClient = new HttpClient();
       return await httpClient.GetAsync(new Uri("http://httpbin.org/ip"));
     }
   }
 }
 </nowiki>
