Backslash in endpoint - rest

I need to consume an endpoint from SoapUI which contains a backslash like:
mydomain/myservice/{id_resource}
and the assignment:
id_resource = numbers\numbers
The problem here is that when I executed the request, the consumed url is mydomain/myservice/numbers%40%5Cnumbers, and if I check the option of disabling the URL-encoding, it ignores the backslash () between the numbers of the id_resource, going to an url like mydomain/myservice/numbersnumbers.
I've tried to scape the character with another backslash, like java or other languages, but it doesn´t work.
It works fine if I consume the service with postman, so it is not a problem of the logic consumed.
So, is it possible to consume an url containing a backslash from SoapUI?

There is an option to disable URL encoding for the selected parameter which would assist with this.

Mojolicious route with a parameter not matching if the parameter contains %2f

I have the following route
$r->get('/select_folder/:mail')->to('mail#change_folder');
It works well almost every time but when the route contains the %2f sequence of characters, equivalent to / it works as if %2f is a path separatator instead of a escaped sequence.
This is an example input:
http://127.0.0.1:5000/select_folder/%5bGmail%5d%2fDestacados
This is part of the error:
None of these routes could generate a response for your GET request for /select_folder/[Gmail]/Destacados, maybe you need to add a new one?
I would like to know some way to get a parameter like this as an url part without using GET or POST parameters.
You can use wildcard placeholders to allow / to be part of the matched parameter.
$r->get('/select_folder/*mail')->to('mail#change_folder');
The reason why %2F is interpreted as a / is because the URL is decoded before being applied to routing.
Finally I have discovered how to use regular expressions to solve the problem.
$r->get('/select_folder/:folder'=>[folder=>qr/.*/])->to('mail#change_folder');
I made :folder match any character, now it is working.

Springboot doesn't let through percentage and backslash in URL

We got a get request that sends string characters in url, so we use path variables to receive them. Apparently there is no way that the calling service would change its method of calling backend so we need to be able to accept a url with the following unencoded characters:
When percentage sign % is sent a http 400 is returned. It does go through if the two characters following % make up an UTF-encoded character
Backslash is converted into a forward slash. I need it to stay backslash.
I'm guessing these might be Tomcat or servlet configuration issues.
(spring boot version 1.5.14.RELEASE)
Percent signs (%) should be no problem if you properly URL encode them (%25). However, slashes and backslashes will not work with Tomcat, even if you encode them (%2F and %5C).
You could set the following properties when running the application:
-Dorg.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true
-Dorg.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH=true
However, this won't fix the issue, because in this case, those encoded slashes will be recognized as real ones. So, let's say you have the following controller:
#ResponseBody
#RequestMapping("/api/{foo}")
public String getFoo(#PathVariable String foo) {
return foo;
}
Well, then if you call /api/test%5Ctest, it won't be able to find the correct path. A solution to this problem is to use wildcard matchers and to parse the URL itself from the incoming HttpServletRequest:
#RequestMapping("/api/**")
public String getFoo(HttpServletRequest request) {
// ...
}
Another solution is to use a completely different web container. For example, when using Jetty, this isn't a problem at all, and URL encoded slashes and backslashes will both work.
Spring 5 now blocks encoded percent signs by default. To enable them, create a new Bean that calls setAllowUrlEncodedPercent()
#Bean
public HttpFirewall allowEncodedParamsFirewall() {
StrictHttpFirewall firewall = new StrictHttpFirewall();
firewall.setAllowUrlEncodedPercent(true);
return firewall;
}
There are similar method-calls for forward- and backwards-slash
What you are experiencing is not specific to Spring Boot. Instead, it's a restriction of HTTP.
The HTTP standard requires that any URL containing the percent characters must be decoded by the web server (cf page 36):
If the Request-URI is encoded using the "% HEX HEX" encoding [42], the
origin server MUST decode the Request-URI in order to properly
interpret the request.
As a result, it's not possible to escape the slash character reliably.
Therefore, when the slash is used in a URL – with or without encoding – it will be treated as a path separator. So it cannot be used in a Spring Boot path variable. Similar problem exist for the percent sign and backslash.
Your best options are to use query parameters or a POST request.
In the following URL, the value test_with_/and_% is transmitted:
https://host/abc/def?text=test_with_%2F_and%25
final String path =
request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE).toString();
final String bestMatchingPattern =
request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE).toString();
String arguments = new AntPathMatcher().extractPathWithinPattern(bestMatchingPattern, path);
if (null != arguments && !arguments.isEmpty()) {
pattern = pattern + '/' + arguments;
}
I also faced similar problem and I have used this so hope this might help

How do I prevent mule from encoding the query-param?

In a HTTP request, I am adding a token as a query-param.
It seems that mule is encoding the value.
- If I add the parameter, mule will encode it in the way it is wrong.
- If I add already encoded parameter, mule will double encode it and therefore won't be usable anymore.
So the question is: Is there a way or a workaround to prevent mule from encoding the URL query-param?
Example of the parameter: {AES}ZEoksxIg484magPtWwNUUQ==;iT0kI2HsqGkh%2Bdc2baW2B4dNR2vouKkWQsDTdbMP8us=
My colleague found a workaround for this, so I'm sharing it here.
Apparently, you can set a variable before the HTTP request and add the manually encoded value. Let's call it ourTokenVariable In my example above that would be %7BAES%7DZEoksxIg484magPtWwNUUQ%3D%3D%3BiT0kI2HsqGkh%252Bdc2baW2B4dNR2vouKkWQsDTdbMP8us%3D
After that, you can use this newly created variable directly in the url path. For example: /example/someapi?someToken=[#flowvars.ourTokenVariable]
This way you don't need to use uri-param or query-param anymore (where mule is double encoding the value). The value will be taken 'as is'.

How to build a Uri in Spray?

I would like to make a simple GET request via Spray with a few query parameters
Get("http://localhost/user?email=abc+a#abc.com")
However + means a space in application/x-www-form-urlencoded content resulting the call to http://localhost/user?email=abc a#abc.com (with a space instead of plus sign).
I could use a non-Spray java.net.URLEncoder to encode the URL before passing it to the GET request however I doing this every time seems like a hack.
Is there a Spray way of applying query parameters and encoding them?
Uri("http://localhost/").withQuery(Map("email"->"abc+a#abc.com")) is a nice way to construct a Uri but it doesn't encode the params as well...
Actually Uri("http://localhost/").withQuery(Map("email"->"abc+a#abc.com")) works fine as it encodes the special symbols.
However, Uri("http://localhost/").withQuery("email=abc+a#abc.com") doesn't.
I use java.net.URLEncoder. I believe that is the accepted method.
It would be nice if that happened automatically!

Tomcat, JAX-RS, Jersey, #PathParam: how to pass dots and slashes?

Having a method like this:
#GET #Path("/name/{name}")
#Produces(MediaType.TEXT_PLAIN)
public String getProperty(#PathParam("name") String name) {
System.out.println(name);
}
How do I pass a value like "test./test"?
/name/test./test gives HTTP 404
/name/test.%2Ftest gives HTTP 400
/name/test.%252Ftest prints test%2Ftest
But if I do name = URLDecoder.decode(name); it prints /test and the first part of test. disappears.
There is one or two questions like this already but they are old and there was no good solution found, I thought I'll ask again.
The pattern in the #Path annotation is internally turned into a regular expression, with the template parts matching only selected characters by default. In particular, they normally don't match / characters; that's almost always the right thing to do (as it lets you put templates part way through a path) but in this case it isn't as you're wanting to consume the whole subsequent path. To get everything, we have to override the regular expression fragment for that particular template; this is actually pretty easy, since we just put in the template fragment a : followed by the RE that we want to use:
#GET #Produces(MediaType.TEXT_PLAIN)
#Path("/name/{name:.+}")
public String getProperty(#PathParam("name") String name) {
return name;
}
This will match all characters after the /name/ (up to but not including any ? query part) but will only match if there's something there at all. Be aware that if you have any other #Path("/name/...") things about, things can get really confusing! So don't do that.
If you using tomcat, and want pass / in pathparam. besides the #Path("/name/{name:.+}") stuff as 'Donal Fellows' said, you should add -Dorg.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true to your jvm arguments, see also tomcat security-howto.
Try specifying the encoding type, the following works for me with /name/test.%252Ftest:
System.out.println(URLDecoder.decode(name, "UTF-8"));
return URLDecoder.decode(name, "UTF-8");
Glassfish v4 accept encoded scape for slash %2f. Then we can pass the encoded String test.%2Ftest and get the result test./test using URLDecoder.decode(name, "UTF-8"). I think this is a better solution especially when you have many params in one request. Using the path #Path("/name/{name:.+}") is great solution when we have few parameters in a request.
Using %252f complicates the client request becouse are needed to contruct the encoding request String manually. With glassfish v4 it's easy to use percent encoding with URLEncoder.encode in client and URLDecoder.decode in server to wished Strings. The most programing languages has percent encoding and decoding, therefore it's perfect solution.
I tried enable encoded slash in glassfish v3 but no success, here is the sintaxe I tried used
bin\asadmin set configs.config.server-config.network-config.protocols.protocol.http-listener-1.http.encoded-slash-enabled=true configs.config.server-config.network-config.protocols.protocol.http-listener-1.http.encoded-slash-enabled=true
Command set executed successfully.
