My JSON looks something like this:
{
"Master" : {
"Major" : "S",
"Minor" : "E",
"IPAddress" : "0.0.0.0",
"Detail":"<root>
<key keyname=\"state\">3</key>
<key keyname=\"oldState\">1</key>
<key keyname=\"currency\"></key>
<key keyname=\"denomination\"></key></root>",
"SourceCreateDate" : "2014-04-03T14:02:57.182+0200"
},
"Messages" : [{
"MessageCode" : "0",
"MessageType" : "8"
}]
}
I'm getting an 'Invalid Characters found' error when validating this. Where are the invalid characters and how can I make this JSON valid?
{
"Master": {
"Major": "S",
"Minor": "E",
"IPAddress": "0.0.0.0",
"Detail": "<root><key keyname=\"state\">3</key><key keyname=\"oldState">1</key><key keyname=\"currency\"></key><key keyname=\"denomination\"></key></root>",
"SourceCreateDate": "2014-04-03T14:02:57.182+0200"
},
"Messages": [
{
"MessageCode": "0",
"MessageType": "8"
}
]
}
JSON validator: http://jsonlint.com/
Edit: Explication: when you open a " you need to close it on the same line. So you have to put your xml on a single line or to escape it.
JSON only accepts single line Strings.
A work-around would be:
"Detail": [
"<root>",
",<key keyname=\"state\">3</key>",
"<key keyname=\"oldState\">1</key>",
"<key keyname=\"currency\"></key>",
"<key keyname=\"denomination\"></key></root>"
],
You also have the option to replace line breaks into \n.
The invalid characters are the line breaks in the "Detail" element. You'll need to escape them. Something like the solution presented here should work.
try this,
{
"Master": {
"Major": "S",
"Minor": "E",
"IPAddress": "0.0.0.0",
"Detail": "<root><key keyname=\"state\">3</key><key keyname=\"oldState\">1</key><key keyname=\"currency\"></key><key keyname=\"denomination\"></key></root>",
"SourceCreateDate": "2014-04-03T14:02:57.182+0200"
},
"Messages": [
{
"MessageCode": "0",
"MessageType": "8"
}
]
}
i think there were some hidden junk characters were there, like next line(line breaks) or tab spaces etc.. that why it was giving error. so make sure "Details" key will be there in single line

I'm trying to create a new language for syntax highighting in Visual Studio Code for the CPU12 assembly language. When I use the new language in a new .asm file, the editor knows that the comment character is (it adds a semicolon to a line when I type ctrl-k ctrl-c), but the text is white instead of the default comment color green. Do I need to specify to use the default vscode theme? If so, where?
package.json
{
"name": "cpu12",
"displayName": "cpu12",
"description": "cpu12",

}
}

{
"comments": {
// symbol used for single line comment. Remove this entry if your language does not support line comments
"lineComment": ";"
},
// symbols used as brackets
"brackets": [
["{", "}"],
["[", "]"],
["(", ")"]
],
// symbols that are auto closed when typing
"autoClosingPairs": [
["{", "}"],
["[", "]"],
["(", ")"],
["\"", "\""],

],
// symbols that that can be used to surround a selection
"surroundingPairs": [
["{", "}"],
["[", "]"],
["(", ")"],
["\"", "\""],
["'", "'"]
]
}
(My ./syntaxes/cpu12.tmLanguage.json is empty.)
The problem was actually because ./syntaxes/cpu12.tmLanguage.json was empty. You need to specify in the .json file how to color line comments:
./syntaxes/cpu12.tmLanguage.json
{
"$schema": "https://raw.githubusercontent.com/martinring/tmlanguage/master/tmlanguage.json",
"name": "cpu12",
"scopeName": "source.cpu12",

{
"comment": "Line Comments -- Asterisk only works at beginning of line",
"match": "((;|^\\*).*$)",
"captures": {
"1" :{
"name": "comment.line.cpu12"
}
}
}
]

I'm using Talend ETL Tool and extracting data from json files and storing them in Mysql database.
But I get the error while reading in very first json. For reading json I'm using tExtractJSONFileds component.
I'm sure about the configuation set up in talend etl tool its right. I believe there is some problem in json file.
While extracting the component shows error like this
Exception in component tExtractJSONFields_1

I dont know how to deal with JSONs, So Acc to this error can anyone help me where could be the error in JSON file ?
Is there any value passed as NULL or something else ?

You have extra empty commas in your sample json.
Your Sample Json should look like
[{
"tstamp": "123456",
"event": "tgegfght",
"is_duplicate": false,
"farm": "dyhetygdht",
"uid": "tutyvbrtyvtrvy",
"clientip": "52351365136",
"device_os_label": "MICROSOFT_WINDOWS_7",
"device_browser_label": "MOZILLA_FIREFOX",
"geo_country_code": "MA",
"geo_region_code": "55",
"geo_city_name_normalized": "agadir",
"referer": "www.abc.com",
"txn": "etvevv5r",
"txn_isnew": true,
"publisher_id": 126,

}]
OR
[
{
"somethinghere": "its value"
},
"somethingelse": "its value"
]
Your sample json is not valid json, due to the spurious extra commas on the second and last lines. Json only allows commas BETWEEN elements of a vector or object, and empty elements are not allowed.
I have a very complex JSON and a snippet of it is below:
var designerJSON=
{
"nodes":
[
{
"NodeDefinition": {
"name": "Start",
"thumbnail": "Start.png",
"icon": "Start.png",
"info": "Entry point ",
"help": "Start point in your workflow.",
"workflow ": "Start",
"category": "Basic",
"ui": [
{
"label": "Entry point",
"category": "Help",
"componet": "label",
"type": "label"
}
]
},
"States": [
{
"start": "node1"
}
]
},.......
]
}
I would like to get the value of "start" in States. But I am stuck in the first step of entering into JSON. When I try
console.log(designerJSON["nodes"]);
I am getting Undefined.
I want the value of start. Wich is designerJSON["nodes"]["States"]["start"].
Can you help.
Thanks in advance
designerJSON["nodes"]["States"]["start"] won't do it.
designerJSON["nodes"] is a list, as is States, so you need to access individual items by index (or iteration).
In the example you have given you need to use this:
designerJSON['nodes'][0]['States'][0]['start']
or this (cleaner IMO):
designerJSON.nodes[0].States[0].start
You have an array in JSON.
instead of
designerJSON["nodes"]["States"]["start"]
use
designerJSON["nodes"][0]["States"][0]["start"]
ps. pay attention on how code is formatted in the topic.
pps. using brackets for accessing properties in js is "bad style" (due to js hint recommendations). better access those via dot, e.g:
designerJSON.nodes[0].States[0].start
I have a large JSON file that I'm trying to parse with JSON Slurper. The JSON file consists of information about bugs so it has things like issue keys, descriptions, and comments. Not every issue has a comment though. For example, here is a sample of what the JSON input looks like:
{
"projects": [
{
"name": "Test Project",
"key": "TEST",
"issues": [
{
"key": "BUG-1",
"priority": "Major",
"comments": [
{
"author": "a1",
"created": "d1",
"body": "comment 1"
},
{
"author": "a2",
"created": "d2",
"body": "comment 2"
}
]
},
{
"key": "BUG-2",
"priority": "Major"
},
{
"key": "BUG-3",
"priority": "Major",
"comments": [
{
"author": "a3",
"created": "d3",
"body": "comment 3"
}
]
}
]
}
]
}
I have a method that creates Issue objects based on the JSON parse. Everything works well when every issue has at least one comment, but, once an issue comes up that has no comments, the rest of the issues get the wrong comments. I am currently looping through the JSON file based on the total number of issues and then looking for comments using how far along in the number of issues I've gotten. So, for example,
parsedData.issues.comments.body[0][0][0]
returns "comment 1". However,
parsedData.issues.comments.body[0][1][0]
returns "comment 3", which is incorrect. Is there a way I can see if a particular issue has any comments? I'd rather not have to edit the JSON file to add empty comment fields, but would that even help?
You can do this:
parsedData.issues.comments.collect { it?.body ?: [] }
So it checks for a body and if none exists, returns an empty list
UPDATE
Based on the update to the question, you can do:
parsedData.projects.collectMany { it.issues.comments.collect { it?.body ?: [] } }
How to update multiple documents in Solr 4.5.1 with JSON? I tried this but it does not work:
POST /solr/mycore/update/json:
{
"commit": {},
"add": {
"overwrite": true,
"doc": [{
"thumbnail": "/images/404.png",
"url": "/404.html?1",
"id": "demo:/404.html?1",
"channel": "demo",
"display_name": "One entry",
"description": "One entry is not enough."
}, {
"thumbnail": "/images/404.png",
"url": "/404.html?2",
"id": "demo:/404.html?2",
"channel": "demo",
"display_name": "Another entry",
"description": "Another entry is required."
}
]
}
}
Solr expects one "add"-key in the JSON-structure for each document (which might seem weird, if you think about the original meaning of the key in the object), since it maps directly to the XML format when doing the indexing - and this way you can have metadata for each document by itself.
{
"commit": {},
"add": {
"doc": {
"id": "321321",
"name": "barfoo"
}
},
"add": {
"doc": {
"id": "123123",
"name": "Foobar"
}
}
}
.. works. I think allowing an array as the element referenced by "add" would make more sense, but I haven't dug further into the source or know the reasoning behind this.
I understand that (at least) from versions 4.0 and older of solr, this has been fixed. Look at http://wiki.apache.org/solr/UpdateJSON.
In ./exampledocs/books.json there is an example of a json file with multiple documents.
[
{
"id" : "978-0641723445",
"cat" : ["book","hardcover"],
"name" : "The Lightning Thief",
"author" : "Rick Riordan",
"series_t" : "Percy Jackson and the Olympians",
"sequence_i" : 1,
"genre_s" : "fantasy",
"inStock" : true,
"price" : 12.50,
"pages_i" : 384
}
,
{
"id" : "978-1423103349",
"cat" : ["book","paperback"],
"name" : "The Sea of Monsters",
"author" : "Rick Riordan",
"series_t" : "Percy Jackson and the Olympians",
"sequence_i" : 2,
"genre_s" : "fantasy",
"inStock" : true,
"price" : 6.49,
"pages_i" : 304
},
...
]
While #fiskfisk answer is still a valid JSON, it is not easy to be serializable from a data structure. This one is.
elachell is correct that the array format will work if you are just adding documents with the default settings. Unfortunately, that won't work if, for instance, you need to add a custom boost to some of the documents or change the overwrite setting. You then have to use the full object structure with an "add" key for each of them, which as they pointed out, makes this frustratingly annoying to try to serialize from most languages which don't allow the same key more than once in an object:
{
"commit": {},
"add": {
"doc": {
"id": "321321",
"name": "barfoo"
},
"boost": 2.0
},
"add": {
"doc": {
"id": "123123",
"name": "Foobar"
},
"boost": 1.5,
"overwrite": false
}
}
Update for SOLR 8.8 (and maybe lower).
The following JSON works for /update/json:
{
'add': [
{'id': '123', 'field1': 'foo'},
{'id': '124', 'field1': 'foo'}
],
'delete': ['111', '106']
}
Another option if you are on Solr 4.10 or later is to use a custom JSON structure and tell Solr how to index it (not sure how to add boosts with this method either, but it's a nice option if you already have a data struct in JSON and don't want to convert it over to Solr's format). Here's the Solr documentation on this option:
