I have a ruby hash where the keys are urls and the values are integers. I convert the hash to JSON and I'm wondering if I'll be able to send the JSON inside a url via an AJAX request and then pull that JSON from a params hash.
Also, I am going to be sending a JSONifyed ruby hash back to the client. If I have a success callback in my AJAX function where I receive the data in a data variable, how do I parse that JSON with JQuery?
Please let me know if I need to be more specific.

Output: In this way, one can easily read a JSON response from a given URL by using urlopen() method to get the response and then use json. loads() to convert the response into a JSON object.
To get JSON from a REST API endpoint, you must send an HTTP GET request and pass the "Accept: application/json" request header to the server, which will tell the server that the client expects JSON in response.
To post a JSON to the server using Python Requests Library, call the requests. post() method and pass the target URL as the first parameter and the JSON data with the json= parameter. The json= parameter takes a dictionary and automatically converts it to a JSON string.
JSON streaming comprises communications protocols to delimit JSON objects built upon lower-level stream-oriented protocols (such as TCP), that ensures individual JSON objects are recognized, when the server and clients use the same one (e.g. implicitly coded in).
Yes, you can with no problem. No manual encoding/decoding needed!
Your code would be like this:
var jsonParam = '{"name":"Edgar"}'; //Sample json param
$.ajax({
...
type: "get", //This sends in url
data: {jsonParam: jsonParam}, //This will encode your json for url automatically
dataType: "json", //With this the response will be automatically json-decoded!
success: function(response){ //Assuming your server output was '{"lastName":"Villegas"}' as string
alert(response.lastName);
}
});
As you can see, no manual encoding/decoding was needed. Jquery handles it all!
Hope this helps. Cheers
PS: If, for some reason, you need to encode/decode your json manually for url use javascript's encodeURIComponent(string) and $.parseJSON(jsonString) methods.
