Hi im building a REST API to upload files.
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import org.apache.http.HttpEntity;
#Path("/api")
public class RestAPI {
private final String UPLOADED_FILE_PATH = "C:/ProgramData/XXXX/";
#GET
public String getFile() {
return "Loading File...";
}
#POST
#Path("/image-upload")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(HttpEntity input) throws IOException {
// Do stuff
return Response.status(200).entity("Uploaded file name : " + "").build();
}
Uploader Class:
import java.io.File;
import org.apache.http.HttpEntity;

import org.apache.http.impl.client.HttpClientBuilder;
public class DemoFileUploader {
public static void main(String args[]) throws Exception {
DemoFileUploader fileUpload = new DemoFileUploader();
File file = new File("C:/Users/tdr/Desktop/TestFile.txt");
// Upload the file
fileUpload.executeMultiPartRequest("http://localhost:8080/MediaHandler/mediahandler/api/image-upload",
file, file.getName(), "File Uploaded :: TestFile.txt");
}
public void executeMultiPartRequest(String urlString, File file, String fileName, String fileDescription)
throws Exception {
// default client builder
CloseableHttpClient httpClient = HttpClientBuilder.create().build();
HttpPost postRequest = new HttpPost(urlString);
try {

System.out.println("Response: " + response);
System.out.println("Response Entity: " + response);
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
and i get the following output:

I tried to follow all examples i found, but all of them are similar to my code. Do u guys can tell me where the bug is?
im sending a multipart/form-data and my restapi is expecting multipart/form-data...
Can you remove this annotation:
#Consumes(MediaType.MULTIPART_FORM_DATA)
or request header must contains Content-Type: MediaType.MULTIPART_FORM_DATA

I was Trying to Automate a Web Service and I am passing the XML in the form of a String and later converting it to String Entity and Setting the Entity. But I don't know why it is throwing 400 Error. I am new to WebServices Automation could any please help me on this.

Your XML is invalid, it start with double quote instead of <?xml, change your assignment to start with:
String xml = "<?xml version ... –

I have hid my key.
As per RFC https://www.rfc-editor.org/rfc/rfc6265#page-7 It is allowed to have two headers with same key of "Set-Cookie". The example provided in RFC is -
Set-Cookie: SID=31d4d96e407aad42; Path=/; Secure; HttpOnly
Set-Cookie: lang=en-US; Path=/; Domain=example.com
How do I achieve same with Jetty(or any other servlet container)? When I call httpServletResponse.addHeader this way-
httpServletResponse.addHeader("Set-Cookie", "SID=31d4d96e407aad42; Path=/; Secure; HttpOnly");
httpServletResponse.addHeader("Set-Cookie", "lang=en-US; Path=/; Domain=example.com");
I see that the second addHeader() doesn't add a new header. According to javadoc for this method-
Adds a response header with the given name and value. This method
allows response headers to have multiple values.
So it seems that multiple values of allowed but I am not sure how to go about having multiple "Set-Cookie" in servlet response.
Setting Cookies directly like that is a bit awkward, considering that the Servlet API has methods specifically for working with Cookies.
Anyway, tested on Jetty 9.3.0.v20150612 and it works as expected.

It's probably not the answer you're looking for but I just tried this myself and it worked right away:
Set-Cookie:SID=31d4d96e407aad42; Path=/; Secure; HttpOnly
Set-Cookie:lang=en-US; Path=/; Domain=example.com
Set-Cookie:JSESSIONID=76A68D96ED044DDFF0CC266810F52DDA; Path=/; HttpOnly
That's how the response looked like. Maybe it's the problem of your particular web container, or your implementation.
Try to debug the application (using remote debugging facility) to figure out where the header gets lost.
I've implemented a REST service on Glassfish server (GF4) and also a small client program to test it. But the server responds with a "Status 415 - Unsupported Media Type" error. Please have a look at my code and give me some hints.

As you can see, I'm setting the content type to "multipart/form-data" and use a MultipartEntityBuilder to create the data to send. I also use the Apache HTTPClientBuilder class to post the data to the server.
On server side, the postXml method isn't called at all, even when my debug console says the constructer has been called and puts Mediatype: multipart/form-data as result.
If you need further infos, please let me know. I've googled so many sites, but haven't come across a solution for my problem. Thanks in advance.
I am trying to do a PHP GET request to a website:
The problem is that this website will only process my request if I attach Cookie information to the header of the request.
Or in picture terms, if I disable cookies in my browser, I get this:
Which means the website recognises that it's my first time 'visiting' the site.
Problem is, that if I now use the search bar on the top right, it will not process this request:
it will just show the same (general) screen.
E.g.: if I have cookies disabled and I search for "AAPL", it will not show any results.
Now if I have cookies enabled, the request is handled just fine:
And so the "AAPL" results are shown.
You can try this yourself as well:
With cookies enabled, visit http://www.pennystocktweets.com/user_posts/feeds?cat=search&lptyp=prep&usrstk=AAPL
With cookies disabled, visit the link again: http://www.pennystocktweets.com/user_posts/feeds?cat=search&lptyp=prep&usrstk=AAPL
Now compare the responses, only the first one is correct.
This means that the website only works after the client has downloaded a cookie, and then has made another (new) GET request to the server with this Cookie information attached.
(Does this imply that the website needs a session-cookie to function correctly?)
Now what I'm trying to do is imitate the request with Apache HttpClient like so:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.net.CookieHandler;
import java.net.CookieManager;
import java.net.HttpURLConnection;

public static void main(String[] args) throws Exception {
String ticker = "AAPL";
String lptyp = "prep";
int opid = 0;
int lpid = 0;
downloadTweets test = new downloadTweets();
String url = test.constructURL(ticker, lptyp, opid, lpid);
// make sure cookies is turn on
CookieHandler.setDefault(new CookieManager());
downloadTweets http = new downloadTweets();
String page = http.GetPageContent(url, ticker);
System.out.println(page);
}
public String constructURL(String ticker, String lptyp, int opid, int lpid)
{
String link = "http://www.pennystocktweets.com/user_posts/feeds?cat=search" +
"&lptyp=" + lptyp +
"&usrstk=" + ticker;
if (opid != 0)
{
link = link +
"&opid=" + opid +
"&lpid=" + lpid;
}
return link;
}
private String GetPageContent(String url, String ticker) throws Exception {
HttpGet request = new HttpGet(url);
String RefererLink = "http://www.pennystocktweets.com/search/post/" + ticker.toUpperCase();
request.setHeader("Host", "www.pennystocktweets.com");
request.setHeader("Connection", "Keep-alive");
request.setHeader("Accept", "*/*");
request.setHeader("X-Requested-With", "XMLHttpRequest");
request.setHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.57 Safari/537.36");
request.setHeader("Referer", RefererLink);
request.setHeader("Accept-Language", "nl-NL,nl;q=0.8,en-US;q=0.6,en;q=0.4,fr;q=0.2");
HttpResponse response = client.execute(request);
int responseCode = response.getStatusLine().getStatusCode();
System.out.println("\nSending 'GET' request to URL : " + url);
System.out.println("Response Code : " + responseCode);
BufferedReader rd = new BufferedReader(
new InputStreamReader(response.getEntity().getContent()));
StringBuffer result = new StringBuffer();
String line = "";
while ((line = rd.readLine()) != null) {
result.append(line);
}
// set cookies
setCookies(response.getFirstHeader("Set-Cookie") == null ? "" :
response.getFirstHeader("Set-Cookie").toString());
return result.toString();
}
public String getCookies() {
return cookies;
}
public void setCookies(String cookies) {
this.cookies = cookies;
}
}
Now, the same thing holds: if I attach (my) cookie information, the response works just fine, and if I don't the response doesn't work.
But I don't know how to get the cookie information and then use it in a new GET request.
So my question is:
How can I make 2 requests to a website such that:
On the first GET request, I get cookie information from the website and store this in my Java program
On the second GET request, I use the stored cookie information (as a Header) to make a new request.
Note: I don't know if the cookie is a normal cookie or a session cookie but I suspect it's a session-cookie!
All help is greatly appreciated!
As the documents of Apache commons httpclient states in the HttpClient Cookie handling part:
HttpClient supports automatic management of cookies, including allowing the server to set cookies and automatically return them to the server when required. It is also possible to manually set cookies to be sent to the server.
Whenever the http client receives cookies they are persisted into HttpState and added automatically to the new request. This is the default behavior.
In the following example code, we can see the cookies returned by two GET requests. We can't see directly the cookies sent to the server, but we can use a tool such as a protocol/net sniffer or ngrep to see the data transmitted over the network:
import java.io.IOException;
import org.apache.commons.httpclient.Cookie;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.HttpState;
import org.apache.commons.httpclient.cookie.CookiePolicy;
import org.apache.commons.httpclient.methods.GetMethod;
public class HttpTest {
public static void main(String[] args) throws HttpException, IOException {
String url = "http://www.whatarecookies.com/cookietest.asp";
HttpClient client = new HttpClient();
client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
HttpMethod method = new GetMethod(url);
int res = client.executeMethod(method);
System.out.println("Result: " + res);
printCookies(client.getState());
method = new GetMethod(url);
res = client.executeMethod(method);
System.out.println("Result: " + res);
printCookies(client.getState());
}
public static void printCookies(HttpState state){
System.out.println("Cookies:");
Cookie[] cookies = state.getCookies();
for (Cookie cookie : cookies){
System.out.println(" " + cookie.getName() + ": " + cookie.getValue());
}
}
}
This is the output:
Result: 200
