I'm trying to make a get request to Firebase. In my url, I have to send the auth token which is very long (more than 900 characters). I create the url this way:
var url =
Uri.https('firebaseio.com', '/mydb.json?auth=$authToken&orderBy="userId"&equalTo="$userId');
But the url is not complete when I print it (the last characters are always lacking) and hence the request does not work. Anyone knows a solution for that?
Your URL isn't actually being cut. The print function can have a limit on its line length when being using in Flutter. Look elsewhere for your issue.
It likely has something to do with your misuse of quotes within your string. It's not normal to have quotes in your query parameters that are opened but not closed.
You can also improve this code by using the optional third queryParameters parameter of the Uri.https constructor to handle your query parameters:
var url = Uri.https(
'firebaseio.com',
'/mydb.json',
{
'auth': authToken,
'orderBy': '"userId"',
'equalTo': '"$userId"',
},
);

I'm attempting to construct a series of Paw calls using the variables feature. I have one situation I'm unable to solve.
At authentication into the server I'm using, I get a JSON response, with one value that looks like this:
endpoint = "https://sub.something.com/thingone/thingtwo.php?token=sometoken&id=blahblah"
The endpoint portion "https://sub.something.com/" is then used as the base for subsequent calls, where a call might be "GET https://sub.something.com/data?id=123".
I don't want to hardcode the endpoint in Paw, as the endpoint will vary based on factors I can't predict at my end.
Is there a way to do basic string processing like this either in Paw, or by calling out to a shell script and using the return value of said script as a Paw variable?
That's doable using that RegExp Match dynamic value extension. Click on that previous link and hit Install Extension.
Type "Regexp" in the field you expect this value to be used. Pick Regexp Match from the completion results:
Then enter a regexp that matches your need, https?://[^/]+/? should be good:
I've put your example string in the screenshot above to show that it works, but you can instead put a "pointer" (Response Dynamic Value) to the response you want:
In the choices, pick Response Parsed Body if you want to parse a JSON or XML from the reponse. If the string is simply in plain text in the response body, pick Response Raw Body.
Once these steps are completed, you've got a working "Pointer" + "Parser" to the response that extract the part of the string you need. You can do the same operation with another regex for the token…
Tip: these dynamic value tokens can be selected like text and copy/pasted (Cmd+C/Cmd+V) :-)
Hi I am attempting to initiate a query to my backend on Kinvey which is backed by a MongoDB. They require passing URL parameters as such:
?query={"firstName":"James"}
I have tried every imaginable way of setting up these parameters in PAW but either get a success response with no filtering of the data or an error message of URL not supported when I try using a Raw Query String.
I have ran the query using their (Kinvey) backend API interface and it works fine in filtering the results so the problem definitely lies within PAW. I am currently using version 3.0.9. Any suggestions or is this just a bug that needs to be fixed?
Thanks!
I've just tried this setup in Paw and I have a few recommendations:
Paw will URL-encode the chars { and " as you can see if you open the HTTP preview in the bottom panel
Trying to send a similar query via Chrome (to test with another app to make sure Paw behaves correctly), I see that the query is URL encoded (try this query https://echo.paw.cloud/?query={"firstName":"James"} you'll see that the browser actually URL-encodes the characters { and " when sending. So the behavior is the same with Paw.
I don't think these two chars ({ and ") are valid HTTP if they are not URL-encoded, so I'm sure your server is expecting them encoded anyway
Testing this exact query in Paw, works for me, so please try these exact steps: go to URL Params, in the first column enter query and {"firstName":"James"} in the second column. Then using the HTTP preview mentioned above, make sure Paw is sending the request you're expecting.
Lastly, it's more like a tip, but as your value is JSON, I recommend that you use the JSON dynamic value to generate the JSON. It will be visually better for you, and will make sure you send valid JSON. For that, right click on the value field, and select Values > JSON. Here's some example:
When I tried to parse this URL:
http://localhost:3000/torrent?previous=%2Ftorrent%3Fprevious%3D%252Fuser%26route%3D&route=torrent-item
I was expecting route = 'torrent-item' (String), but FlowRouter router value is ["", "torrent-item"] (Array)
online - https://ts-vcompile.herokuapp.com/user#!/torrent?previous=%2Ftorrent%3Fprevious%3D%252Fuser%26route%3D&route=torrent-item
repo - https://github.com/HedCET/TorrentSearch
There is one key route in queryparameter which has no value. So default value assumed is an empty string. It will always return you an array of keys with same name(in this case 'route').
So you will not get route = 'torrent-item'
previous=%2Ftorrent%3Fprevious%3D%252Fuser%26route%3D&route=torrent-item
Your URL decodes as
http://localhost:3000/torrent?previous=/torrent?previous=%2Fuser&route=&route=torrent-item
cf: http://meyerweb.com/eric/tools/dencoder/
so you have &route=&route=torrent-item which will return ["", "torrent-item"] since route is there twice.
You just need to figure how to encode this URL properly to read it right.
If it's a URL you are reading from somewhere, then you need to parse the multiple arguments of the array to find what you want.
I have an MVC3 Action that takes a parameter (a URL) that may have a query string in it. My action signature looks like this:
GetUrl(string url)
I expect to be able to send it urls, and it works every time unless there is a query string in the url. For example, if I navigate to:
MyController/GetUrl/www.google.com
the url parameter comes accross as "www.google.com" -Perfect. However, if I send
MyController/GetUrl/www.google.com/?id=3
the url parameter comes accross as "www.google.com/" How do I get MVC3 to give me the whole URL in that parameter? -Including the query string?
It's simple enough to just URL.Encode the passed in URL on the page but you're opening your self to some possible security problems.
I would suggest you encrypt the url then encode it then pass that as your value, the protects you from having people just passing in anything into your app.
That's because system considers id=3 as its own query string. When you construct the link in the view, you need to use #Url.Encode to convert raw url string to encoded string to be accepted as parameter of the controller.
I am creating a HTTPS connection and setting the request property as GET:
_httpsConnection = (HttpsConnection) Connector.open(URL, Connector.READ_WRITE);
_httpsConnection.setRequestMethod(HttpsConnection.GET);
But how do I send the GET parameters?
Do I set the request property like this:
_httpsConnection.setRequestProperty("method", "session.getToken");
_httpsConnection.setRequestProperty("developerKey", "value");
_httpsConnection.setRequestProperty("clientID", "value");
or do I have to write to the output stream of the connection?
or do I need to send the Parameter/Values by appending it to the url?
Calling Connection.setRequestProperty() will set the request header, which probably isn't what you want to do in this case (if you ask me I think calling it setRequestHeader would have been a better choice). Some proxies may strip off or rewrite the name of non-standard headers, so you're better off sticking to the convention of passing data in the GET URL via URL parameters.
The best way to do this on a BlackBerry is to use the URLEncodedPostData class to properly encode your URL parameters:
URLEncodedPostData data = new URLEncodedPostData("UTF-8", false);
data.append("method", "session.getToken");
data.append("developerKey", "value");
data.append("clientID", "value");
url = url + "?" + data.toString();
HTTP GET send data parameters as key/value pairs encoded within URL, just like:
GET /example.html // without parameters
GET /example.html?Id= 1 // with one basic parameter
GET /example.html?Id=1&Name=John%20Doo // with two parameters, second encoded
Note follow rules for character separators:
? - split URL in two pieces: adddress to left and paremeters to right
& - must be used to separate on parameter from another
You must know your platform specific native string encode function. Javascript uses escape, C# uses HttpUtility.UrlEncode
Yep, headers and properties are pretty much all you can send in a GET. Also, you're limited to a certain number of characters, which is browser dependent - I seem to recall about 1024 or 2000, typically.
