how can i retrive parameters from EncodeURL using jsp? - jsp-tags

I have problem with URLEncoding in JSP. My problem is that I have done URL Encoding and I redirected that page to another one called save.jsp.
My code is:
String basePath= request.getScheme()+"://" + request.getServerName() +
":" +request.getServerPort() + request.getContextPath();
String level1approval="12345X";
**encodeUrl** = response.encodeURL(basePath+"/"+"level1approval.jsp" +
"?user_id=+level1approval");
In the JSP I'm trying to get the user_id value but it is giving me null.
What is wrong?

I think you fail to close properly the string.
response.encodeURL(basePath + "/level1approval.jsp?user_id=" + level1approval);

PayPal IPN Validation Not Working Only for recurring_payment txn_type

My PayPal IPNs are validating fine, except for those with a txn_type of recurring_payment. When I pass the message to the validation endpoint, I'm converting the body into a query string using
var verificationString = '?cmd=_notify-validate';
Object.keys(body).map((key) => {
verificationString = verificationString + '&' + key + '=' + body[key];
return key;
});
My best guess is that this is messing with the order of the properties. PayPal's documentation states:
Your listener HTTPS POSTs the complete, unaltered message back to PayPal; the message must contain the same fields (in the same order) as the original message and be encoded in the same way as the original message.
But I didn't think Object.keys(body).map would rearrange anything in Nodejs. Any suggestions?
Found the solution. Turns out that PayPal allows user fields to contain things like backslash, newline characters, etc. This specific IPN had an address field with a \r\n newline between the street and apartment number. Using my original code, this was somehow being encoded different.
Instead of assembling the query string like in my original question, I now assemble it like this, since it preserves all characters and encoding:
var verificationString = '?cmd=_notify-validate&' + request.rawBody.toString();
And that solved the problem!

JScript Escape an ampersand in payload data for URL

I am attempting to launch a view using the following JS function:
$('#filterTop').click(function () {
var filterValue = $('#filterValueTop').val();
refreshView(`#Url.Action(Model.Action, Model.Controller)?pageSize=#Model.PageSize&pageNumber=#Model.PageNumber&sortDesc=#Model.SortDescending&filterType=#Model.FilterType&filterValue=${filterValue}&showAll=#Model.ShowAll` + `#Model.Payload`, '#Model.ResultView');
});
It worked great until I needed to append a static payload to the end of the URL. The relevant part is line 3 at the end:
&showAll=#Model.ShowAll` + `#Model.Payload`
I am assigning #Model.Payload a value of:
opts.Payload = "&batchID=" + batchID;
or "&batchID=25". The resulting URL is:
https://localhost:44303/Employee/Repaginate?pageSize=20&pageNumber=1&sortDesc=True&filterType=Name&filterValue=Jes&showAll=False&batchID=25
For some reason, it's translating the "&" to "&a.m.p;" (with no periods) which isn't a valid URL. I've tried various methods of escaping the character like using "%26", "/&", and several other garden varieties but alas, my attempts have been in vain. Any suggestions on what I am doing wrong?

Pass Values to Web Api URL in Query string C#

I am new to Web API and need to pass values dynamically from UI(Windows Application) in URL as posted below with value parameters in Bold.
URL:http://openbasket-quote.sit.svc/v3/allQuotes/**{number}**/version/**{version}**?format=OrderGroupXml&country=**{country}**&ignoreExpirationDate=true
i have done in this way.
string eQuoteURL = eTempQuoteURL + eQuoteNo + "/" + "version" + "/" + versionNo + "?" + "format=OrderGroupXml&country=" + country + "&ignoreExpirationDate=true";
Is there any other way to pass values to URL.
You can use a composite format string:
string eQuoteURL = string.Format("{0}{1}/version/{2}?
format=OrderGroupXml&country={3}&ignoreExpirationDate=true",
eTempQuoteURL,
eQuoteNo,
versionNo,
country);
In C# 6, you can use an interpolated string:
string eQuoteURL = $"{eTempQuoteURL}{eQuoteNo}/version/
{versionNo}?format=OrderGroupXml&country={country}&ignoreExpirationDate=true";
Or you could use a library like Flurl or RestSharp.

Read parameter from URL - plus character converted to space [duplicate]

Say I have a URL
http://example.com/query?q=
and I have a query entered by the user such as:
random word £500 bank $
I want the result to be a properly encoded URL:
http://example.com/query?q=random%20word%20%A3500%20bank%20%24
What's the best way to achieve this? I tried URLEncoder and creating URI/URL objects but none of them come out quite right.
URLEncoder is the way to go. You only need to keep in mind to encode only the individual query string parameter name and/or value, not the entire URL, for sure not the query string parameter separator character & nor the parameter name-value separator character =.
String q = "random word £500 bank $";
String url = "https://example.com?q=" + URLEncoder.encode(q, StandardCharsets.UTF_8);
When you're still not on Java 10 or newer, then use StandardCharsets.UTF_8.toString() as charset argument, or when you're still not on Java 7 or newer, then use "UTF-8".
Note that spaces in query parameters are represented by +, not %20, which is legitimately valid. The %20 is usually to be used to represent spaces in URI itself (the part before the URI-query string separator character ?), not in query string (the part after ?).
Also note that there are three encode() methods. One without Charset as second argument and another with String as second argument which throws a checked exception. The one without Charset argument is deprecated. Never use it and always specify the Charset argument. The javadoc even explicitly recommends to use the UTF-8 encoding, as mandated by RFC3986 and W3C.
All other characters are unsafe and are first converted into one or more bytes using some encoding scheme. Then each byte is represented by the 3-character string "%xy", where xy is the two-digit hexadecimal representation of the byte. The recommended encoding scheme to use is UTF-8. However, for compatibility reasons, if an encoding is not specified, then the default encoding of the platform is used.

What every web developer must know about URL encoding
I would not use URLEncoder. Besides being incorrectly named (URLEncoder has nothing to do with URLs), inefficient (it uses a StringBuffer instead of Builder and does a couple of other things that are slow) Its also way too easy to screw it up.
Instead I would use URIBuilder or Spring's org.springframework.web.util.UriUtils.encodeQuery or Commons Apache HttpClient.
The reason being you have to escape the query parameters name (ie BalusC's answer q) differently than the parameter value.
The only downside to the above (that I found out painfully) is that URL's are not a true subset of URI's.
Sample code:
import org.apache.http.client.utils.URIBuilder;
URIBuilder ub = new URIBuilder("http://example.com/query");
ub.addParameter("q", "random word £500 bank \$");
String url = ub.toString();
// Result: http://example.com/query?q=random+word+%C2%A3500+bank+%24
You need to first create a URI like:
String urlStr = "http://www.example.com/CEREC® Materials & Accessories/IPS Empress® CAD.pdf"
URL url = new URL(urlStr);
URI uri = new URI(url.getProtocol(), url.getUserInfo(), url.getHost(), url.getPort(), url.getPath(), url.getQuery(), url.getRef());
Then convert that URI to an ASCII string:
urlStr = uri.toASCIIString();
Now your URL string is completely encoded. First we did simple URL encoding and then we converted it to an ASCII string to make sure no character outside US-ASCII remained in the string. This is exactly how browsers do it.
Guava 15 has now added a set of straightforward URL escapers.
The code
URL url = new URL("http://example.com/query?q=random word £500 bank $");
URI uri = new URI(url.getProtocol(), url.getUserInfo(), IDN.toASCII(url.getHost()), url.getPort(), url.getPath(), url.getQuery(), url.getRef());
String correctEncodedURL = uri.toASCIIString();
System.out.println(correctEncodedURL);
Prints
http://example.com/query?q=random%20word%20%C2%A3500%20bank%20$
What is happening here?
1. Split URL into structural parts. Use java.net.URL for it.
2. Encode each structural part properly!
3. Use IDN.toASCII(putDomainNameHere) to Punycode encode the hostname!
4. Use java.net.URI.toASCIIString() to percent-encode, NFC encoded Unicode - (better would be NFKC!). For more information, see: How to encode properly this URL
In some cases it is advisable to check if the URL is already encoded. Also replace '+' encoded spaces with '%20' encoded spaces.
Here are some examples that will also work properly
{
"in" : "http://نامه‌ای.com/",
"out" : "http://xn--mgba3gch31f.com/"
},{
"in" : "http://www.example.com/‥/foo",
"out" : "http://www.example.com/%E2%80%A5/foo"
},{
"in" : "http://search.barnesandnoble.com/booksearch/first book.pdf",
"out" : "http://search.barnesandnoble.com/booksearch/first%20book.pdf"
}, {
"in" : "http://example.com/query?q=random word £500 bank $",
"out" : "http://example.com/query?q=random%20word%20%C2%A3500%20bank%20$"
}
The solution passes around 100 of the test cases provided by Web Platform Tests.
Using Spring's UriComponentsBuilder:
UriComponentsBuilder
.fromUriString(url)
.build()
.encode()
.toUri()
The Apache HttpComponents library provides a neat option for building and encoding query parameters.
With HttpComponents 4.x use:
URLEncodedUtils
For HttpClient 3.x use:
EncodingUtil
Here's a method you can use in your code to convert a URL string and map of parameters to a valid encoded URL string containing the query parameters.
String addQueryStringToUrlString(String url, final Map<Object, Object> parameters) throws UnsupportedEncodingException {
if (parameters == null) {
return url;
}
for (Map.Entry<Object, Object> parameter : parameters.entrySet()) {
final String encodedKey = URLEncoder.encode(parameter.getKey().toString(), "UTF-8");
final String encodedValue = URLEncoder.encode(parameter.getValue().toString(), "UTF-8");
if (!url.contains("?")) {
url += "?" + encodedKey + "=" + encodedValue;
} else {
url += "&" + encodedKey + "=" + encodedValue;
}
}
return url;
}
In Android, I would use this code:
Uri myUI = Uri.parse("http://example.com/query").buildUpon().appendQueryParameter("q", "random word A3500 bank 24").build();
Where Uri is a android.net.Uri
In my case I just needed to pass the whole URL and encode only the value of each parameters.
I didn't find common code to do that, so (!!) so I created this small method to do the job:
public static String encodeUrl(String url) throws Exception {
if (url == null || !url.contains("?")) {
return url;
}
List<String> list = new ArrayList<>();
String rootUrl = url.split("\\?")[0] + "?";
String paramsUrl = url.replace(rootUrl, "");
List<String> paramsUrlList = Arrays.asList(paramsUrl.split("&"));
for (String param : paramsUrlList) {
if (param.contains("=")) {
String key = param.split("=")[0];
String value = param.replace(key + "=", "");
list.add(key + "=" + URLEncoder.encode(value, "UTF-8"));
}
else {
list.add(param);
}
}
return rootUrl + StringUtils.join(list, "&");
}
public static String decodeUrl(String url) throws Exception {
return URLDecoder.decode(url, "UTF-8");
}
It uses Apache Commons' org.apache.commons.lang3.StringUtils.
Use this:
URLEncoder.encode(query, StandardCharsets.UTF_8.displayName());
or this:
URLEncoder.encode(query, "UTF-8");
You can use the following code.
String encodedUrl1 = UriUtils.encodeQuery(query, "UTF-8"); // No change
String encodedUrl2 = URLEncoder.encode(query, "UTF-8"); // Changed
String encodedUrl3 = URLEncoder.encode(query, StandardCharsets.UTF_8.displayName()); // Changed
System.out.println("url1 " + encodedUrl1 + "\n" + "url2=" + encodedUrl2 + "\n" + "url3=" + encodedUrl3);

The new line code "\n" and/or #NewLine does not add new line to field

I'm getting document history, adding "\n" and existing document history. Code executes without any error. But when I see it in web everything on one line. In notes client, document history is shown as one line of activity.
Tried with #Newline and same issue.
What I'm doing wrong?
Thanks in advance.
Here is sample code:
var myvar="\n"
var h=getComponent("docHistory1").getValue();
var msg="Stage 2 - LAB Manager approved and completed check. Send to Chemist: " + unm + " + dt1;
document1.setValue("DocHistory", h + myvar + msg);
document1.save();
Use a Multiline Edit Box xp:inputTextarea instead of a Computed field xp:text and set it to Read only readonly="true".
As an alternative you could still use a Computed field replacing all '\n' with '<br />' and setting escape="false".
Just to give an alternative solution, you could use a style on the computed text component with "white-space:pre" (or pre-line or pre-wrap, see this for the differences) and that would preserve the newlines in the content.
