i have a link in my app with the following URL:
http://www.mysite.com/test?group=MyGroup
the issue is one of the groups is called Group A & B
when i try this and parse it on the serverside (through Request.QueryString["Group"])
http://www.mysite.com/test?group=Group A & B
i get
group='Group A ' (because of the &)
how can i change my URL so it can deal with values with "&" inside of them.
Use the URLEncode method to make your text safe for a querystring.
var url = "http://www.mysite.com/test?group=" +
System.Web.HttpServerUtility.UrlEncode("Group A & B");

This should be extremely simple but for some reason it doesn't seem to work. I'm trying to pull the URLs of display placements using the DISPLAY_PERFORMANCE_REPORT but instead of URLs it's just returning "--".
The code I'm using is:
var report = AdWordsApp.report(
"SELECT CampaignName, Clicks, FinalAppUrls, FinalUrls " +
"FROM PLACEMENT_PERFORMANCE_REPORT " +
"WHERE Clicks > 0 " +
"DURING LAST_30_DAYS");
var rows = report.rows();
while (rows.hasNext()) {
var row = rows.next();
var url = row["FinalUrls"];
Logger.log(url);
}
I've tried logging the CampaignName and clicks and they're working as expected, so can't understand what the issue is here. The only thing I can think of is that in the reference guide it says:
List of final URLs of the main object of this row. UrlList elements
are returned in JSON list format
I'm not entirely sure what JSON list format is, but when I log the typeof url it says it's a string, so thought it shouldn't be an issue.
The FinalAppUrls and FinalUrls list the target URLs that you set on the individual managed placements.
If you're interested in the URL (domain, rather) of the placement itself, you'll have to request either the Criteria or the DisplayName field in your report——they both contain the domain of the placement.
Let's imagine I have the following parts of a URL:
val url_start = "http://example.com"
val url_part_1 = "&fields[...]&" //This part of url can be in the middle of url or in the end
val url_part_2 = "&include..."
And then I try to concatenate the resulting URL like this:
val complete_url = url_start + url_part_2 + url_part_1
In this case I'd get http://example.com&include...&fields[...]& (don't consider syntax here), which is one & symbol between URL parts which means that concatenation was successful, BUT if I use different concat sequence in a different request like this:
val complete_url = url_start + url_part_1 + url_part_2
I'd get http://example.com&fields[...]&&include..., to be specific && in this case. Is there a way to ensure that concatenation is safer?
To keep you code clean use an array or object to keep your params and doin't keep "?" or "&" as part of urlStart or params. Add these at the end. e.g.
var urlStart = "http://example.com"
var params=[]
params.push ('a=1')
params.push ('b=2')
params.push ('c=3', 'd=4')
url = urlStart + '?' + params.join('&')
console.log (url) // http://example.com?a=1&b=2&c=3&d=4
First, you should note that it is invalid to have query parameters just after domain name; it should be something like http://example.com/?include...&fields[...] (note the /? part, you can replace it with / to make it a path parameter, but it's not likely that the router of the website supports parameters like this). Refer, for example, to this article: https://www.talisman.org/~erlkonig/misc/lunatech%5Ewhat-every-webdev-must-know-about-url-encoding/ to know more about what URLs can be valid.
For the simple abstract approach, you can use Kotlin's joinToString():
val query_part = arrayOf(
"fields[...]",
"include..."
).joinToString("&")
val whole_url = "http://example.com/?" + query_part
print(whole_url) // http://example.com/?fields[...]&include...
This approach is abstract because you can use joinToString() not only for URLs, but for whatever strings you want. This also means that if there will be an & symbol in one of the input strings itself, it will become two parameters in the output string. This is not a problem when you, as a programmer, know what strings will be joined, but if these strings are provided by user, it can become a problem.
For URL-aware approach, you can use URIBuilder from Apache HttpComponents library, but you'll need to import this library first.
How can I do about " and ' for saving object and use it for JSON.parse() in javascript?
Because I have some strings and user can type using " and ' in a single string, for example "some description like "abc" for '3 feet" or "about 3'5 feet" or "wel"come"". When I want to transform into a JSON, especially when I want to parse in view side, for example:
var test = '${test as JSON}';
It breaks because contains escape like \"
However, if only contains " and use this JSON.parse("[{"abc": "asda"das"}]"), still invalid, because need escape.
So, I really don't know what I should do in thoses cases. I need some explanation how to fix, avoid or magic.
JSON can be treated directly as Object in Javascript. So you can simply write:
var test = ${(test as JSON).toString()}
Optionally, you can pass true to the toString() method to make the JSON pretty string or Object.
var test = ${(test as JSON).toString(true)}
I have the followigurl localhost.dev?q=dyYJDXWoTKjj9Za6Enzg4lB+NHJsrZQehfY1dqbU1fc= and extract the query string as follows:
NameValueCollection query = HttpUtility.ParseQueryString(actionContext.Request.RequestUri.Query);
string str1 = query[0];
If i call query.ToString() it shows the correct characters query string. However, when I access the value from the NameValueCollection 'query[0]' the "+" is replaced by a empty " " i.e. dyYJDXWoTKjj9Za6Enzg4lB NHJsrZQehfY1dqbU1fc=
I've tried specifing different encoding and using the Get method from the namevaluecollection. I've also tried spliting the string, but the "+" is being removed each time. Has anyone got any ideas? Many thanks
You can't use this chars in the url variables, you need use URLEncode and URLDecode of HttpUtility class to convert this into a valid url.
I hope this help you.
What's the best practice for adding a query parameter to a URL in Tritium (Moovweb SDK)? Looking for something that works where you don't know if the URL has a "?" and other query parameters already.
Here's a short snippet of Tritium that should help you out in your Moovweb project. Just replace the "query_param=true" bit with the query parameter you want to add.
It selects the href of every a tag, then looks for any existing query parameters (by looking for a "?" in the href). If there are some existing, it just appends the new query parameter. If there are no existing query parameters on the href, it uses the ? to add one to the URL.
$q = "query_param=true"
$("//a[#href]") {
%s = fetch("./#href")
match(%s) {
with(/\?/) {
attribute("href", %s + "&" + $q)
}
else() {
attribute("href", %s + "?" + $q)
}
}
log(%s)
}
(You could also turn that into a function if you wanted!)
I think there is going to be a new URL scope soon so you'll be able to do things like this much more easily!
