I am writing a macro send multiple emails that are customized based on the data required.
For example:
Subject: <name>, Thank you for visiting <store>
At the moment, I can only pull , but I have no idea how to also add so 'Content' will both of them.
Content = Replace(msg.Subject, "<name>", first_name + " " + last_Name)
Replace(msg.Subject, "<store>", store_name)
^ essentially I want to combine both of these so the macro will pull both.
You can do it in multiple steps:
Content = Replace(msg.Subject, "<name>", first_name + " " + last_Name)
Content = Replace(Content, "<store>", store_name)
Or you could nest your Replace statements:
Content = Replace(Replace(msg.Subject, "<name>", first_name + " " + last_Name), "<store>", store_name)
If you ended up with a large number of tokens to replace (or an ever growing dynamic number of them) then you could get fancy and iterate through the string to identify tokens and swap them out inside the loop, but that would be overkill here.
I have a string with constant value and I want to pass it to rename_to header while using MV gateway.
I have tried below code snippet and one by adding the variable in context and then using it with #basePath
#Value("${basePath:/home/}")
String basePath;
.enrichHeaders(h -> h
.headerExpression(RENAME_TO, "'${basePath}' + headers[file_remoteFile]")
.headerExpression(REMOTE_FILE, "headers[file_remoteFile]")
.header(REMOTE_DIRECTORY, "headers[file_remoteDirectory]"))
I am getting error on startup. How can I give basePath in my application.properties
#Value("${basePath:/home/}")
String basePath;
Means "inject '/home/' into variable basePath if there is no basePath property.
You can't use fields from the enclosing class like that in the SPeL expression, and you can't use property placeholders in SpEL there; you have to concatenate the strings in the java.
.headerExpression(RENAME_TO, "'" + this.basePath + "'" + " + headers[file_remoteFile]")
We have a process creating uuid's in TSQL using the following:
SELECT Cast( HASHBYTES('MD5', 'some string') as uniqueidentifier)
I created an API in node js, and they want me to be able to create the same unique identifier off of 'some string'. Is that possible? Using crypto, I can get the same hex value as the HASHBYTES command (crypto.createHash('md5').update('some string').digest("hex")), but I don't know how I would convert it to the same uuid that TSQL is returning.
I believe what I want is a v3 uuid, but I don't know what the namespace would be. I thought maybe SSMS was using some value specific to the server to create the uuid, but I was able to get the same value on three different servers, two on our network and another on a random EC2 instance.
Am I misunderstanding something very basic about uuid's? Or is there some namespace specific to Microsoft SQL Server, consistent between all servers?
Node libraries I've checked out: uuid,
uuid-1345,
uuid-lib,
guid
I've also tried the aguid library, which seems to do what I want but in SHA256. I borrowed the code and switched it to md5, but then I saw that all that library is doing is taking a hash and adding a 4 or 8 at certain character indices.
A friend figured out how TSQL handles cast as uniqueidentifier. They just rearrange the characters of the hash! Here's how you'd do it in Javascript:
var castAsUuid = function(str){ var x = str.substring(6, 8) + str.substring(4, 6) + str.substring(2, 4) + str.substring(0, 2) + '-' + str.substring(10, 12) + str.substring(8, 10) + '-' + str.substring(14, 16) + str.substring(12, 14) + '-' + str.substring(16, 20) + '-' + str.substring(20, 32)
return x.toUpperCase()
}
They seem to be doing it the same way every time (tried about ten different strings). Good times.
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);
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);
