I am doing Tableau integration with web project using java script api. I have configured my ip in tableau server using commnad :tabadmin set wgserver.trusted_hosts "" and respective commands .But I am not able to get the ticket, ended up with -1. I have followed all configuration steps.
public class TableauServlet extends javax.servlet.http.HttpServlet {
private static final long serialVersionUID = 1L;
public TableauServlet() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
final String user = "raghu";
final String wgserver = "103.xxx.xxx.xx";
final String dst = "views/Regional/College?:iid=1";
final String params = ":embed=yes&:toolbar=yes";
String ticket = getTrustedTicket(wgserver, user, request.getRemoteAddr());
if ( !ticket.equals("-1") ) {
response.setStatus(HttpServletResponse.SC_MOVED_TEMPORARILY);
response.setHeader("Location", "http://" + wgserver + "/trusted/" + ticket + "/" + dst + "?" + params);
}
else
// handle error
throw new ServletException("Invalid ticket " + ticket);
}
// the client_ip parameter isn't necessary to send in the POST unless you have
// wgserver.extended_trusted_ip_checking enabled (it's disabled by default)
private String getTrustedTicket(String wgserver, String user, String remoteAddr)
throws ServletException
{
OutputStreamWriter out = null;
BufferedReader in = null;
try {
// Encode the parameters
StringBuffer data = new StringBuffer();
data.append(URLEncoder.encode("username", "UTF-8"));
data.append("=");
data.append(URLEncoder.encode(user, "UTF-8"));
data.append("&");
data.append(URLEncoder.encode("client_ip", "UTF-8"));
data.append("=");
data.append(URLEncoder.encode(remoteAddr, "UTF-8"));
// Send the request
URL url = new URL("http://" + wgserver + "/trusted");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
out = new OutputStreamWriter(conn.getOutputStream());
out.write(data.toString());
out.flush();
// Read the response
StringBuffer rsp = new StringBuffer();
in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ( (line = in.readLine()) != null) {
rsp.append(line);
}
return rsp.toString();
} catch (Exception e) {
throw new ServletException(e);
}
finally {
try {
if (in != null) in.close();
if (out != null) out.close();
}
catch (IOException e) {}
}
}
}
I think you are missing 'target_site' parameter in your URL where you get trusted ticket, its needed if you don't have the 'views/Regional/College' in your default site.
I had gone through a lot of frustration with the '-1' ticket too!
One thing you might try is restarting the tableau server after you have added your web server IP to the trusted_hosts of tableau.
Another thing we ended up doing was adding both the internal ip and external ip of the web server to trusted_hosts on tableau. Since you are using 103.xxx.xxx.xx as your tableau server I am assuming both servers live on the same internal network. You might try that if everything else fails.
My code is almost exactly same as yours and works fine. So if your problem persists, it must be something related to configuration.
here is my code:
private String getAuthenticationTicket(String tableauServerUserName,String tableauServerUrl, String targetSite) {
OutputStreamWriter out = null;
BufferedReader in = null;
try {
StringBuffer data = new StringBuffer();
data.append(URLEncoder.encode("username", Constant.UTF_8));
data.append("=");
data.append(URLEncoder.encode(tableauServerUserName, Constant.UTF_8));
data.append("&");
data.append(URLEncoder.encode("target_site", Constant.UTF_8));
data.append("=");
data.append(URLEncoder.encode(targetSite, Constant.UTF_8));
URL url = new URL(tableauServerUrl + "/" + "trusted");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
out = new OutputStreamWriter(conn.getOutputStream());
out.write(data.toString());
out.flush();
StringBuffer rsp = new StringBuffer();
in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
rsp.append(line);
}
return rsp.toString();
} catch (Exception ex) {
//log stuff, handle error
return null;
} finally {
try {
if (in != null)
in.close();
if (out != null)
out.close();
} catch (IOException ex) {
//log stuff, handle error
}
}

I am working on a java plugin that is supposed to recieve some info from a js vue3 program and then do a URL post operation, and then return some of the info found back to the js code. I am using capacitor and android. This is my error message:
2022-08-22 13:46:23.773 27544-27544/org.theguy.GptEtc E/Capacitor/Console: File: http://localhost/js/app.6577adf2.js - Line 1 - Msg: Uncaught (in promise) SyntaxError: Unexpected token o in JSON at position 1
I think this means that something other than valid JSON is being delivered to the js code. I know that the app is delivering info to the java android class. This is some of my java code.
#CapacitorPlugin(name = "URLPOST")
public class PluginURLPost extends Plugin {
#PluginMethod()
public void post(PluginCall call) {
String post_url = call.getString("post_url", "");
String bearer = call.getString("bearer", "pipeline_");
JSObject ret = new JSObject();
try {
String value = this.doPost(post_url, bearer);
System.out.println("value " + value);
Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(value));
ResultPreview preview = gson.fromJson(reader, ResultPreview.class);
String val = preview.getResult_preview()[0][0];
val = "result string here."; // <-- add this for easy testing
ret.put("response_text", val.replace("\n", "\\n"));
System.out.println("response here: " + val);
}
catch (Exception e) {
e.printStackTrace();
}
//call.setKeepAlive(true);
call.resolve(ret);
}
OkHttpClient client = new OkHttpClient();
public static final MediaType JSON
= MediaType.parse("application/json; charset=utf-8");
String doPost(String post_url, String bearer ) throws IOException {
// ... do some post request here ...
return response_body;
}
}
class ResultPreview {
#SerializedName("result_preview")
String [][] result_preview ;
public void setResult_preview(String[][] result) {
this.result_preview = result;
}
public String[][] getResult_preview() {
return this.result_preview;
}
}
This is some of my js code.
import { registerPlugin } from "#capacitor/core";
const URLPOST = registerPlugin("URLPOST");
const request = {
"line": line,
"pipeline_model": details[engine]["app_model"].trim(),
"bearer": details[engine]["api_key"].trim(),
"post_url": details[engine]["url"].trim(),
"length": 25,
"top_k": 50
};
console.log("request", request);
var {response_text} = await URLPOST.post(request);
console.log("response_text 1",response_text);
I don't know what to do.
I tried this, and things work better. I don't know if this is the ultimate solution.
#PluginMethod()
public void post(PluginCall call) {
bridge.saveCall(call); // <-- add this
call.release(bridge); // <-- add this
String pipeline_model = call.getString("pipeline_model", "pipeline_");
String post_url = call.getString("post_url", "");
JSObject ret = new JSObject();
try {
String value = this.doPost(post_url);
Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(value));
ResultPreview preview = gson.fromJson(reader, ResultPreview.class);
String val = preview.getResult_preview()[0][0];
ret.put("response_text", val.replace("\n", "\\n"));
System.out.println("response here: " + val);
}
catch (Exception e) {
e.printStackTrace();
}
call.resolve(ret);
}
This is not found on the capacitor site, but instead I found it digging around the internet.
I am trying to use httpurlconnection to post parameters to URL. The httpurlconnection seems to be posting fine when posting values without spaces however the issue appears when something like submit=Login Accountwhich contains a space. I have tried to use a plus symbol and %20 instead of the space however I have been unsuccessful submitting the form.
String requestParameters =“password=test123&confirm=test123&id=2869483&submit=Login Account”;

I am building an android app. I have build a request using OKHTTP and I get the response as a string composed of html css and js content. This response is actualy a form that the user must use to allow the app to communicate with a given website.
Now I want the user to be able to see that response as an html page and clicks on a button to allow the communictaion. Only problem I don't know how to display that response as an html in webview or in the web browser.
From the MainActivity:
Authenticate myAouth = new Authenticate("myCostumerKey","mySecretKey");
try {
myResponse=myAouth.run("myUrlHere");
//System.out.println( myResponse);
} catch (Exception e) {
e.printStackTrace();
}
the Autheticate class
public class Authenticate {
private final OkHttpClient client;
String[] myResponse =new String[2];
public Authenticate( final String consumerKey, final String consumerSecret) {
client = new OkHttpClient.Builder()
.authenticator(new Authenticator() {
#Override public Request authenticate(Route route, Response response) throws IOException {
if (response.request().header("Authorization") != null) {
return null; // Give up, we've already attempted to authenticate.
}
System.out.println("Authenticating for response: " + response);
System.out.println("Challenges: " + response.challenges());
String credential = Credentials.basic(consumerKey, consumerSecret);
Request myRequest =response.request().newBuilder()
.header("Authorization", credential)
.build();
HttpUrl myURL = myRequest.url();
myResponse[0]= String.valueOf(myURL);
return myRequest;
}
})
.build();
}
#RequiresApi(api = Build.VERSION_CODES.KITKAT)
public String[] run(String url) throws Exception {
Request request = new Request.Builder()
.url(url)
.build();
try (Response response = client.newCall(request).execute()) {
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
myResponse[1]=response.body().string();
System.out.println(" URL is "+myResponse[0]+" my response body is "+myResponse[1]);
}
return myResponse;
}}
Any help would be apriciated.

You can use the following code to convert the String to HTML and then display it in a WebView
try {
String html = new String(response, "UTF-8");
String mime = "text/html";
String encoding = "utf-8";
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.loadDataWithBaseURL(null, html, mime, encoding, null);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
In my app, I have created web server which is hosting a web app. All the files of web app are placed in assets folder.
Now, i start the web server by running my application and then from crome brower, I try to run my web app by calling index.html file. The html, css part of the page is getting loaded properly but the images are not getting loaded in the page:
Here is my HttpRequestHandlerCode:

String resp = Utility.openHTMLStringFromAssets(context, "html" + requestUri);
writer.write(resp);
writer.flush();
// }
}
});
((EntityTemplate) entity).setContentType(contentType);
response.setEntity(entity);
}
}
/**

private String contentType(String fileName) {
String ext = "";
int idx = fileName.lastIndexOf(".");
if (idx >= 0) {

}
if (mimeTypes.containsKey(ext)) {
//Log.i("Sushill", "...ext : " + ext);
return mimeTypes.get(ext);
}
else
return "application/octet-stream";
}
To handle image, I tried this but it did not work :
if(contentType.contains("image")) {
InputStream is = Utility.openImageFromAssets(context, "html" + requestUri);
char[] buffer = new char[1024];
try {
Reader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
int n;
while ((n = reader.read(buffer)) != -1) {
writer.write(buffer, 0, n);
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Can someone please help me in figuring out how to load the images also in my browser.
Thanks for any help
Do away with BufferedReader(new InputStreamReader' so you do away with UTF-8 too. Use only InputStream 'is'. Do away with writer. You are not showing what 'writer' is but do away with it. Use the OutputStream of the http connection. Keep the buffer and the loop where you read in the buffer and write from the buffer.
