I am trying to call the USPS API that takes in the zip code and returns XML containing the City Name of the given zip code.
Here is the URL they require:
http://production.shippingapis.com/ShippingAPITest.dll?API=CityStateLookup
&XML=<CityStateLookupRequest USERID="xxxxxxx"><ZipCode ID= "0">
<Zip5>90210</Zip5></ZipCode></CityStateLookupRequest>
In my PHP file, when I echo out the above URL, this is what I get:
http://production.shippingapis.com/ShippingAPITest.dll?API=CityStateLookup&XML=90007
All the XML part of the URL is missing. I need to get curl data from the URL.
Anyone know what I could be missing?

Probably. Maybe, yes. What you describe in your posting sounds like an encoding problem. So you are missing the right encoding.
As you are talking about an URL that is likely URL encoding. Some characters - like space - have a special meaning inside an URL so you can not just use any character as you like, but you need to encode all characters properly.
The exact description how you need to formulate an URL incl. the exact description how URL encoding works is outlined in 2. Characters in the internet standard RFC3986.
PHP functions related to URL encoding are urlencode() and rawurlencode and more likely useful in your case http_build_query().
http://php.net/manual/en/function.urlencode.php should get you started if you want to encode the xml into the URL.

I use file_get_contents() to download a JSON. There're some Chinese characters in the URL, I tried to print the URL out, it's OK. But when I ran the program, the URL I put in the function became error code. How do I know that is this URL links to a JSON that links to a MySQL request, and in the console of MySQL, I saw the URL became error code. I tried lots of ways to change URL string to UTF-8 or GB2312, etc, but none of that works. I Wish I could get help here, thanks.
Its very difficult to understand your question. I think i understood the first part of your question:
I use file_get_contents() to download a JSON. There're some Chinese
characters in the URL, I tried to print the URL out, it's OK. But when
I ran the program, the URL I put in the function became error code.
You try to access a URL containing chinese characters using file_get_contents():
The answer to this is:
You need to encode the part of the url containing chinese characters using urlencode() or rawurlencode().
The main difference between urlencode()and rawurlencode() is, that urlencode() converts spaces to +. rawurlencode() converts spaces to %20.
urlencode is used for Query Parameters as example ?q=my+search+key, in every other case you use rawurlencode.
Example:
$test = 'http://www.example.com/'.rawurlencode('以怎么下载').'.html';
print_r($test);
// $html = file_get_contents($test);
// output:
http://www.example.com/%E4%BB%A5%E6%80%8E%E4%B9%88%E4%B8%8B%E8%BD%BD.html
I hope it solves your problem.
I am getting a URL from server and trying to load the URL in webview. The issue is that the url which I am getting contains non standard characters. The URL is:
https//p-r3.test.abc.com:443%2Ftablet%2Fjsp%2Fgift%2Fipad%2Fgifter%2FgitGiftList.jsp%3FregId%3D74500002%26filterBy%3DviewAll%26pageId%3DourGifty%26sort%3Dcategory%26groupBy%3Dcategory%26view%3Dlist%26categoryId%3D%26addCat%3Dcat100540004&title=re%20-&imgurl=https%3A%2F%2Fm-r3-testy.tr.com%3A443%2Ftablet%2Fimages%2Ft_Full.jpg%3Fwid%3D300%26hei%3D300.
I need to remove characters like %2520, %2F, %3D and other non standard characters from the URL. Anyone has idea to remove this encoding.
Any help would be appreciated
Thanks
%2520 is simply a double-encoded space. Encode it once and you get %20, encode it twice and you get %2520. It's not "non-standard", it's just poorly coded. In theory, there's no reason why you can't just replace %2520 with a space, but for all I know the server-side code is expecting the double-encoded string.
Found the answer.I am removing the encoding using the built in function of iOS.abc = [def stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
and i am loading abc in webview.It is working fine.
Thanks all for the responses.
You seem to have an urlencode() too many, or an urldecode() too few, in the code processing the URL server side.
To avoid multiple encoding, Remove any encoding first
_pdfUrl = [ _pdfUrl stringByRemovingPercentEncoding];
_pdfUrl = [_pdfUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
There is script that receives another url as GET parameter:
script.php?file=http://www.google.com&id=123
The problem is:
when url has parameter itself, it is used as script's parameter, not that url's parameter:
script.php?file=http://www.google.com?q=adsf&lang=en&id=123
URL is http://www.google.com?q=adsf&lang=en, but it is chopped after &, because it is viewed as related to script.php itself.
What can I do about this?
I tired to replace & with %26, but url get broken with it.
You need to encode the value with the percent-encoding.
If you’re using PHP, use rawurlencode (or urlencode if application/x-www-form-urlencoded is expected):
$url = 'http://www.google.com?q=adsf&lang=en';
echo 'script.php?file='.rawurlencode($url);
You need to URL encode the entire URL that you are passing as a parameter to another url (your script). %26 is the correct encoding for an &. Just make sure you decode it server-side before using it. You don't say what language(s) you're using, but most, inc javascript and php have native URL encoding functions.
Try to encode every special character like this:
script.php?file=http%3a%2f%2fwww.google.com%3fq%3dadsf%26lang%3den&id=123
although it might be better and easier to use rawurlencode().
Also, read this about URL encoding.
I have a php which generates an xml file and prints it on screen.
Amongst other variables, it prints an Image link.
The problem is that if this Image link has an '&' character in it, I get an xml error because it isn't encoded properly.
So I solve it by replacing the & sign with &.
Atleast I thought it was solved, now the link to the image is for example like this:
www.domain.com/phones & equipment/img1.jpg
which causes a 404 file not found.
The real path is
www.domain.com/phones & equipment/img1.jpg
So how can I solve this then?
I would prefer not to change the folder names, I simply didn't know this when I created the folders.
Thanks
If it's a URL, you might want to URL encode it instead:
www.domain.com/phones%20%26%20equipment/img1.jpg
try to
www.domain.com/phones+%26+equipment/img1.jpg
You should url encode the link using php urlencode() function. The code for '&' is "%26".
Additionally, if you check IANA RFC regarding URL/URI, you will see that space character is not a valid character and shouldn't be present inside REQUEST URI. Having your URL like www.domain.com/phones-and-equipment/img1.jpg would be much beneficial from SEO standpoint as well.
ADDENDUM: For example, check page 2, section "Unsafe" of RFC 1738 and see why non-printable and non-US-ASCII characters are not safe.
use html_entity_decode to convert & back into an &
see http://php.net/manual/en/function.html-entity-decode.php
The correct representation of the ampersand in an XML file is &. If that isn't working, the problem is with the code that is reading the XML file and deferencing the URI.
I would like file_get_contents to get a url that looks like this: http://wapedia.mobi/sv/Gröt
The problem is that it requests (can't post entire link, sorry): ...wapedia.mobi/sv/Gr%C3%B6t which you can see has been urlencoded, that page does not give me any results.
How can I do this?
According to the PHP manual, you must specifically encode a URL if it contains special characters. This means the function itself should do no special encoding. Most likely your URL is being encoded before being passed to the function, so pass it through urldecode first and see what happens.
Edit: You're saying the encoding is being messed up. Again the PHP manual specifically states that you need to encode urls prior to passing them to file_get_contents. Try encoding the URL, then passing it to the function.
$url = urlencode($url);
file_get_contents($url);
