var data = xhr.responseText;
When I output this console.log(xhr.responseText). Below is my output
["{id:1,name\":\"JOHN\",\"city\":\"null\"}"
,"{\"id\":2,\"name\":\"MICHEAL\,\"city\":\"null\"}"]
How do I get id, name. I tried like this data.id but I get this error
jquery JSON.parse: unexpected end of data.
Update
I am using code igniter with data mapper so my data mapper is giving that json response. Do you know, how I can resolve it.
You've already been told what the problem is in the comments: the JSON generated by the server is invalid. You are probably not using a library to encode your JSON, don't ever encode it by hand.
Your JSON should probably look like the following (when pretty printed) http://jsfiddle.net/7FKWr/
[
{"id": 1, "name": "JOHN", "city": null},
{"id": 2, "name": "MICHEAL", "city": null}

I'm trying to load a json file from a server response and parsing it in flutter, the model i create is working for all the other fields but i'm in trouble with this class
this is a part of the JSON response:
"episodes": {
"1": [
{
"id": "63",
"episode_num": 1,
"title": "Some Name",
"container_extension": "mp4",
"info": {
"director": "",
"plot": "",
"cast": "",
"rating": "",
"releasedate": "",
"movie_image": "",
"genre": "",
"duration_secs": 6495,
"duration": "01:48:15"
}
}
]
}
in this case the entry under episodes is just one but this will represents a season and all the episode inside it, so under episodes many of this entry (undefined number during coding) can be present
At this time, using online json to dart converter tools i can be able to retrive just this one entry but if a response have more than 1 season i can't see it.
There is any way to handle this?
EDIT:
Solved using a for cicle with max value = (json['episodes'].length + 1).
For the info stored inside each 'episodes' value i can use
json['episodes']['$i']
Valid JSON is always convertible to a Dart data structure. But what you may be asking is "can I get nested objects from this?", and that just depends on how hard you want to work. Some JSON-to-Dart tools are better than others and some JSON values are impossible for any automated tool to make sense of. Only real answer is: "it depends".
I have a simple python (version 3.10.2) script that uses the requests library to make a REST call to an API. The call returns a list of objects. I find that the json.loads() function will not parse the JSON returned in the response. It gives me the following error:
TypeError: the JSON object must be str, bytes or bytearray, not list
Oddly, the json.dumps() function can successfully format the same data.
Here is the code:
import requests
import json
def get_groups(url):
# TODO SSL/TLS turned OFF (verify=False)
response = requests.get(url + "/groups", verify=False)
print("status code:", response.status_code)
print("JSON:\n")
print(json.dumps(response.json(), indent=2))
json.loads(response.json())
Here is an example what json.dumps() is outputting:
[
{
"id": 6,
"web_url": "https://<URL redacted>/groups/test",
"name": "test",
"path": "test",
"description": "",
"visibility": "public",
"share_with_group_lock": false,
"require_two_factor_authentication": false,
"two_factor_grace_period": 48,
"project_creation_level": "developer",
"auto_devops_enabled": null,
"subgroup_creation_level": "maintainer",
"emails_disabled": null,
"mentions_disabled": null,
"lfs_enabled": true,
"default_branch_protection": 2,
"avatar_url": null,
"request_access_enabled": true,
"full_name": "test",
"full_path": "test",
"created_at": "2021-08-03T15:41:34.523Z",
"parent_id": null,
"ldap_cn": null,
"ldap_access": null
}
]
I have seen lots of postings about this and every one mentions using json.loads() to parse the JSON data. Not sure why it works for them, but it doesn't work for me.
Any ideas as to what is wrong?
As was pointed out by #tkausl, in this case the HTTP/REST response object returns the JSON data already parsed. For some reason I missed that. I don't need to to use the json library.
Hello I have a JSON in the following format.I need to parse this in the map function to get the gender information of all the records.
[
{
"SeasonTicket" : false,
"name" : "Vinson Foreman",
"gender" : "male",
"age" : 50,
"email" : "vinsonforeman#cyclonica.com",
"annualSalary" : "$98,501.00",
"id" : 0
},
{
"SeasonTicket": true,
"name": "Genevieve Compton",
"gender": "female",
"age": 28,
"email": "genevievecompton#cyclonica.com",
"annualSalary": "$46,881.00",
"id": 1
},
{
"SeasonTicket": false,
"name": "Christian Crawford",
"gender": "male",
"age": 53,
"email": "christiancrawford#cyclonica.com",
"annualSalary": "$53,488.00",
"id": 2
}

I have tried using JSONparser but am not able to get through the JSON structure.I have been advised to use JAQL and pig but cannot do so.
Any help would be appreciated.
What I understand is that you have a huge file with an array of JSONs. Of this, you need to read the same to a mapper and emit say <id : gender>. The challenge is that JSON falls across to multiple lines.
In this is the case, I would suggest you to change the default delimiter to "}" instead of "\n".
In this case, you will be able to get parts of the JSON into the map method as value. You can discard the key ie. byte offset and do slight re-fractor on the value like removing off unwanted [ ] or , and adding chars like "}" and then parse the remaining string.
This solution works because there is no nesting within JSON and } is a valid JSON end delimiter as per the given example.
For changing the default delimiter, just set the property textinputformat.record.delimiter to "}"
Please check out this example.
Also check this jira.
I have a Web application which gets it data from a JSON string.
The JSON is in the following format
{
"contacts": [{
"type": "contact",
"name": "John Doe",
"contact": 1,
"links": ["Spouse", "Friends","Jane Doe","Harry Smith"]
}]
}
Now this is a sample data. My actual DB is in Oracle. My question would be how do I construct this JSON from Oracle.
This is the best method I've come across: http://ora-00001.blogspot.sk/2010/02/ref-cursor-to-json.html.
To summarise:
Use the DBMS_XMLGEN package to generate XML from a SYS_REFCURSOR.
Then transform it using this XSLT.
I like it because there's no manual generation and because you have the option of returning XML too by skipping the final transformation.
I need to implement a simple shell utility in Ruby which parses JSON from a file and return a particular field from it.
JSON examples to be parsed:
{"status": "fail", "messages": ["Out of capacity"]}
{"status": "success", "messages": [], "result": {"node": {"ip": "1.2.3.4", "description": "", "id": 974, "name": "VM#3"}}}
Idea is to create a CLI utility with two parameters: JSON file to read and field from JSON to extract:
./get_json_field.rb ~/tmp.XXXXXX 'result.node.ip'
./get_json_field.rb ~/tmp.XXXXXX 'messages.0'
I'm struggling how to map 2nd parameter to parsed JSON data structure in Ruby. I can write an iterator for sure, splitting string to an array using dot as separator an go through it item by item but this doesn't look like elegant solution.
Any suggestions for more elegant way?
There is nothing wrong with splitting string and going through parts of it:
require 'json'
data1 = JSON.load('{"status": "fail", "messages": ["Out of capacity"]}')
data2 = JSON.load('{"status": "success", "messages": [], "result": {"node": {"ip": "1.2.3.4", "description": "", "id": 974, "name": "VM#3"}}}')
def get_from_json(data, query)
query.split('.').inject(data) do |memo, key|
key = key.to_i if memo.is_a? Array
memo.fetch(key)
end
end
get_from_json(data1, 'messages.0') # => "Out of capacity"
get_from_json(data2, 'result.node.ip') # => "1.2.3.4"
Take a look at jq it might already do what you are looking for.
jq .messages[0]
jq .node.message.ip
