How do I debug a URL in a route in camel? - apache-camel

I'm trying to use two variables in the URL for a Camel route. If I hard code the values in the URL the route works. If I make them dynamic using ${} I get an error message saying Input string was not in a correct format. Here's the code with my attempt to pull the values id1 and id2 from the headers:
from(SOURCE)
.setHeader(Exchange.HTTP_METHOD, simple("GET"))
// .to("http://restUrl:8090/content/json/13/630?bridgeEndpoint=true")
.to("http://restUrl:8090/content/json/${in.header.id1}/${in.header.id2}?bridgeEndpoint=true")
.process(processor);
I've verified that those values exist correctly in the header. What am I doing wrong, and how would I see the value for the dynamically created URL?

AngularJS $location.search does not work with query parameters in the middle of URL

We have a legacy webapp written in AngularJs and it doesn't uses the HTML5 mode in location provider. When we have the URL in following valid format $location.search() returns empty object
https://my.domain.com/path/index.html?param=value#hashpart
But when the URL is in following non-conventional way it returns the object {'param':'value'}
https://my.domain.com/path/index.html#hashpart?param=value
RFC3986 says the fragment should come at the end of the URI
Can anyone help us to understand why? We need the URL in the first format.

Error by reading Header values from Logic App HTTP Request

In a if condition I tried to get a header value (secret key) I'am sending to the Logic App.
The following code is used to get the secret from the header (In this example i have parsed it before)
#body('Parse_Header_from_HTTP_Request')?['headers']?['Secret']
I have also tried the solution from this answered question:
Azure Logic Apps : Get HTTP Request Header Key Value into Conditional Check
The variable is null if I check it on the Run History.
According to your description, I do not know how you parse your header before.
Here I use Parse Json to achieve, you could refer to the screenshot as below:
After setting body('Parse_Json')?['name'] to get name value, the output is as below:
As you have said, you have parsed the header after http request. So, after parsing headers, the value is from parse_json, while you refer to the link you provided which value is from http request header.
Hope it helps you.

Apache Camel Interceptor with regular expression

This is my route. I want to send a file to an Azure blob. I want to set the name of the blob as the file name without extension. I also want to filter out the whitespaces from the file names. I am thinking of using an interceptor
from("file://C:/camel/source1").recipientList(simple("azure-blob://datastorage/container1/${header.fileName}?credentials=#credentials&operation=updateBlockBlob"))
I want to invoke the interceptor only for updateBlockBlob operatin
interceptSendToEndpoint("^(azure-blob:).+(operation=updateBlockBlob)").setHeader("fileName",simple("${file:onlyname.noext}")).convertBodyTo(File.class)
The above code works with interceptFrom().
I tried replacing the regular expression with wild card like azure* i.e interceptSendToEndpoint("azure*"). It did not work
Whats wrong with the above code? Is it because of recipientList?
Also what features does simple have to remove white space?
Is there a better way to generate blob names dynamically?
Here is the documentation from camel on interceptors.
http://camel.apache.org/intercept.html
interceptFrom that intercepts incoming Exchange in the route.
interceptSendToEndpoint that intercepts when an Exchange is about to
be sent to the given Endpoint.
So I suspect the Exchange is already formed and camel expects the url to be resolved.
So the header needs to be set before the exchange is created for the Azure end point.
I did the following. To set the header, I use the interceptFrom, and to convert the object into File I used the inteceptSendToEndPoint
interceptSendToEndpoint("^(azure-blob:).+(operation=updateBlockBlob)").convertBodyTo(File.class)
interceptFrom().setHeader("fileName",simple("${file:onlyname.noext}".replaceAll("[^a-zA-Z\d]")))
Managed to get rid of the whitespace too

$http.post URL is getting trimmed off if URL has "#"

I'm having one Rest API: /myApp/fetchData/User-Name/Password. User-Name and Password will be changed based on the request.
When i call the above restapi like this
/myApp/fetchData/srikanth/Abcdef#g123
the request is going like this:
/myApp/fetchData/srikanth/Abcdef
Basically in the URL text got removed from # character. Is there any way to solve?
Thanks,
Srikanth.
In a URI the # triggers the begins of the "fragment", and ends the path. The fragment usually specify a portion of the resource identified by the path.
When you are post-ing the request from the client, you have to escape special characters. Your request should be:
/myApp/fetchData/srikanth/Abcdef%23g123
There are different way to escaping urls, like the encodeURI or encodeURIComponent function in JS. For example, you may do:
var request = "/myApp/fetchData/srikanth/" + encodeURIComponent("Abcdef#g123");
Then the server have to decode back to the original request.
But: are you sure it is a good solution to send the password plain in that way?

AngularJS $http service has CORS issue. But it should be working for JSONP, right? [duplicate]

I'm trying to load an external page using JSONP, but the page is an HTML page, I just want to grab the contents of it using ajax.
EDIT: The reason why I'm doing this is because I want to pass all the user information ex: headers, ip, agent, when loading the page rather than my servers.
Is this doable? Right now, I can get the page, but jsonp attempts to parse the json, returning an error: Uncaught SyntaxError: Unexpected token <
Sample code:
$.post('http://example.com',function(data){
$('.results').html(data);
},'jsonp');
I've set up a jsfiddle for people to test with:
http://jsfiddle.net/8A63A/1/
http://en.wikipedia.org/wiki/JSONP#Script_element_injection
Making a JSONP call (in other words, to employ this usage pattern),
requires a script element. Therefore, for each new JSONP request, the
browser must add (or reuse) a new element—in other words,
inject the element—into the HTML DOM, with the desired value for the
"src" attribute. This element is then evaluated, the src URL is
retrieved, and the response JSON is evaluated.
Now look at your error:
Uncaught SyntaxError: Unexpected token <
< is the first character of any html tag, probably this is the start of <DOCTYPE, in this case, which is, of course, invalid JavaScript.
And NO, you can't use JSONP for fetching html data.
I have done what you want but in my case I have control of the server side code that returns the HTML.
So, what I did was wrapped the HTML code in one of the Json properties of the returned object and used it at client side, something like:
callback({"page": "<html>...</html>"})
The Syntax error you are facing it's because the library you're using expects json but the response is HTML, just that.
I've got three words for you: Same Origin Policy
Unless the remote URL actually supports proper JSONP requests, you won't be able to do what you're trying to. And that's a good thing.
Edit: You could of course try to proxy the request through your server …
If you really just want to employ the client to snag an HTML file, I suggest using flyJSONP - which uses YQL.. or use jankyPOST which uses some sweet techniques:
jankyPOST creates a hidden iframe and stuffs it with a form (iframe[0].contentWindow.document.body.form.name).
Then it uses HTML5 (watch legacy browsers!) webMessaging API to post to the other iframe and sets iframe's form elements' vals to what u specified.
Submits form to remote server...done.
Or you could just use PHP curl, parse it, echo it, so on.
IDK if what exactly ur using it for but I hope this helps.
ALSO...
I'm pretty sure you can JSONP anything that is an output from server code. I did this with ClientLogin by just JSONPing their keyGen page and successfully consoleLogged the text even though it was b/w tags. I had some other errors on that but point is that I scraped that output.
Currently, I'm trying to do what you are so I'll post back if successful.
I don't think this is possible. JSONP requires that the response is rendered properly.
If you want another solution, what about loading the url in an iframe and trying to talk through the iframe. I'm not 100% positive it will work, but it's worth a shot.
First, call the AJAX URL manually and see of the resulting HTML makes sense.
Second, you need to close your DIV in your fiddle example.
