Require a method to call a URL World_Imagery (MapServer) from client site without redirecting request to proxy.jsp file at server

AdarshSharma — Thu, 28 Jul 2016 12:07:17 GMT

we are using proxy for token services but our web application server not having a internet connectivity because of which it is unable to call URL World_Imagery (MapServer)

Please suggest a method to call this URL World_Imagery (MapServer) without using proxy.jsp & other URL is (10.131.5.244:6080/arcgis/rest/services).

NOTE- we cannot allow internet to our hosting server for security reasons.

Call proxy in my javascript :-

esri.config.defaults.io.proxyUrl = "proxy.jsp";

esri.config.defaults.io.alwaysUseProxy = true;

esriConfig.defaults.io.corsDetection = false;

proxy.jsp :-

<%@page session="false"%>

<%@page import="java.net.*,java.io.*" %>

<%!

String[] serverUrls = {

"http://myserver.mycompany.com/arcgis/rest/services,ayn2C2iPvqjeqWoXwV6rjmr43kyo23mhIPnXz2CEiMA6rVu0xR0St8gKsd0olv8a"

"https://server.arcgisonline.com/ArcGIS/rest/services",

"http://10.131.4.244:6080/arcgis/rest/services,55diNsb4PSZW1pf9MDkTJ1ZGfLDUhc6rn81rg-bIszh9RRN3mi6ImwjrLzQesnI9"

};

try {

String reqUrl = request.getQueryString();

boolean allowed = false;

String token = null;

for(String surl : serverUrls) {

String[] stokens = surl.split("\\s*,\\s*");

if(reqUrl.toLowerCase().contains(stokens[0].toLowerCase())) {

allowed = true;

if(stokens.length >= 2 && stokens[1].length() > 0)

token = stokens[1];

break;

}

if(!allowed) {

response.setStatus(403);

return;

}

if(token != null) {

reqUrl = reqUrl + (reqUrl.indexOf("?") > -1 ? "&" : "?") + "token=" + token;

}

URL url = new URL(reqUrl);

HttpURLConnection con = (HttpURLConnection)url.openConnection();

con.setDoOutput(true);

con.setRequestMethod(request.getMethod());

if(request.getContentType() != null) {

con.setRequestProperty("Content-Type", request.getContentType());

}

con.setRequestProperty("Referer", request.getHeader("Referer"));

int clength = request.getContentLength();

if(clength > 0) {

con.setDoInput(true);

InputStream istream = request.getInputStream();

OutputStream os = con.getOutputStream();

final int length = 5000;

byte[] bytes = new byte[length];

int bytesRead = 0;

while ((bytesRead = istream.read(bytes, 0, length)) > 0) {

os.write(bytes, 0, bytesRead);

}

else {

con.setRequestMethod("GET");

}

out.clear();

out = pageContext.pushBody();

OutputStream ostream = response.getOutputStream();

response.setContentType(con.getContentType());

InputStream in = con.getInputStream();

final int length = 5000;

byte[] bytes = new byte[length];

int bytesRead = 0;

while ((bytesRead = in.read(bytes, 0, length)) > 0) {

ostream.write(bytes, 0, bytesRead);

}

} catch(Exception e) {

response.setStatus(500);

}
