I have a json object which contains some values that include some special chracter. For example {UserName":"UserTest","Password":"OImqNlK/tLwUzKnt1rA1OA=="}
I use it as an object parameter to call to web Api but I can't get it on Api server.
it works fine if I remove the special characters. For example:
{UserName":"UserTest","Password":"OImqNlKtLwUzKnt1rA1OA"}
Please help me fix it. Many thanks!
First page when I put "Json Special Characters" into google : here
To be concrete to your question, this is the way
{UserName":"UserTest","Password":"OImqNlK\/tLwUzKnt1rA1OA=="}

I'm trying to figure out why my parsed request(a json from an jquery ajax, cross domain) is looking a bit strange.
GET /sendjsondata?callback=_testcb&{%22amount%22:1800,%22name%22:%22Vasy%20Jon%22,%22cnp%22:232323,%22coborrower%22:true,%22device%22:%22Desktop%22}&_=1415883870387 404 3.346 ms - 1303
I can create a function to retrieve the piece between braces and then applying a new polish to remove "%22", but I think that I'm dooing a mistake somewhere in my code and that's why I don't obtain a clean json object and maybe someone can tell me where is the issue.
Thank you.
URLs use a special encoding to represent special characters. %22 equals ". Whatever framework you are using should take care of decoding this. Otherwise look for urlencode()/urldecode() functions.
Good day! How are HTML parameters expressed in the routes file? I am trying to pass an HTML but I don't know how. All I know are passing integers ((id: Integer)) and some data types. I tried (content: Html)and (content: Html). I also tried javax.swing.text.html.HTML but it says something about QueryStringBindable. Please help me. Thanks a lot.
Remember that all you pass by route's params will be included in the URL so what is the advantage of using HTML in this place ? GET params should use only simple data types like numerical types, booleans and strings - so you can pass some HTML part as a String (preferably url-encoded or even beter with Base64 encoding).
Much better option is sending it via POST, your URLs won't be terrible long - you won't hit any limitation of URL length, also after common serialization it won't break at special HTML chars.
I'm trying to return an html snippet from a service that can only return valid JSON.
I've tried some things like:
This gets me a bunch of character like \n\n\n\n\t\t\t\t
return JSON.stringify({html: $('body').html()});
or
return JSON.stringify($('body').html());
On the receiving end, I'd like to be able to parse that HTML via Cheerio, or jQuery or JSDom so I can then run queries like $(".some_selector") on that data.
What is the proper way of doing this? Any special libraries / methods that can handle the escaping for me? I've googled it, but haven't had any clear results...
Thanks.
On the receiving end, you need to simply undo the JSON serialization. That's it!
Your HTML will be in its regular format at obj.html, which you can then parse with whatever DOM parser you want.
Well, you are probably going to need to worry about quotes in the HTML (like with attributes) because the could interfere with the quotes that delimit your JSON values.
Here is similar question as well as this web page that explains some of what you need to consider.
Briefly looking at npmsj.org, I didn't see any reputable modules that might help you make HTML JSON compatible, but I think you can probably figure it out fairly easily on your own, given a large enough sample set of HTML. You can always run your JSON through this validator to check it. I suppose you could also simply do a JSON.parse(jsonContainingHtml) on it as well. You'll get an exception if the string is not valid JSON.
If you view the source of a Google+ profile page, it appears rather complex. It seems most of the data is kept in a huge JSON-like objects. However, they don't seem to be really JSON, since they don't get recognized when I try to decode them. I am hoping the format is more clear to other people here. How would you go about parsing it? It seems it would fairly trivial, if you know where to start.
Here is a sample profile, for example: http://plus.google.com/104560124403688998123
Here's a PHP API I'm working on. It can download and parse the data for a profile page and people's public relationships.
https://github.com/jmstriegel/php.googleplusapi
The JSON piece is a bit mangled. To generate valid JSON, you basically have to remove the first 5 characters that prevent XSRF attacks and then add in all the nulls that have been removed. Here's the code specific to handling parsing the weird Google Plus JSON responses:
https://github.com/jmstriegel/php.googleplusapi/blob/master/lib/GooglePlus/GoogleUtil.php
Call GoogleUtil::FetchGoogleJSON( $url ) and you'll get back a giant array that you can then pull data from. Using this, it should be trivial to make a proxy service to translate stuff into valid json(p) for you to use in your own apps.
I don't have access to Google+ yet, so I'll just answer the general question - that is, how to parse JSON.
JSON is just JavaScript, so parsing it is as simple as evaluating the script. To do this, use the eval() JavaScript function.
var obj = eval('{"JSON":"goes here"}');
Another option is to leverage a console tool. Popular modern browsers pretty much all have them. I recommend Firebug for Firefox in particular.
Using Firefox, log into Google+, then open the Firebug console. You can use the console's dir() command to create a browseable representation of the data. Ex:
console.dir(eval('{"JSON":"goes here"}'));
Sorry I can't be more specific about how to get a handle on Google+'s JSON in particular; without access to the service, this is about the best I can do blind. Good luck!
Thanks to Jason for the excellent php class which reads a profile page into an array.
I've used this class as a base and then parsed it, based upon Russell Beattie's python code from the original appspot rss feed application.
Code here
A few notes:
I use this to merge G+ and WP feeds, hence writing posts into an intermediate array ($items).
I have a convention of creating a pseudo title in Google Plus posts, by emboldening a line and adding two newlines before writing the post. The function getTitle strips this out as a better formatted title in my website and getSummary produces the rest of the post with duplicating the title.
It's made up of a number of parts, an object describing your picasa images, one describing the fields on your profile, one describing your friends.
Most of the long numbers are the internal IDs of people, posts and photos. For instance, my ID is 105249724614922381234. Other than that, it could be parsed if you needed to.
how can I do this without getting "forbidden". Other sites do it, for example http://twitter.com?status=http://somesite.com works just fine. I've been looking everywhere for an answer. Please can somebody help! Please note my example is automatically encoded (imagine it without the %3A)
You will need to encode the url. A query string with an unencoded url is going to be a problem.
If you don't encode urls inside urls, then whoever is interpreting it will not see it as a valid URL. This is because in your example
http://twitter.com?status=http%3A//somesite.com
The %3A is a colon. But according to the URI specification, the colon is a schema delimiter (http, ftp, irc, whatever), and a uri can only contain one. And if I've read enough of these specs, I'm guessing it says the equivalent to "servers receiving an badly formed url should return an error message" or "..try to interpret it without guaranteeing a positive response".
Technically the // should also be escaped, since they are path delimiters, but only a server serving static content would react to that.
For the URI specification, see http://labs.apache.org/webarch/uri/rfc/rfc3986.html
If you are asking how to do this in Javascript you should use the escape/unescape and handle the special case of the / character.
