I am trying to parse a JSON file in ActionScript 3.
So far I imported this...
import com.adobe.serialization.json.JSON;
I have created the JSON class:
[Embed(source="myfile.json",mimeType="application/octet-stream")]
private var json_file:Class;
And then I try to parse the JSON
var jsonObj:Object = JSON.decode(json_file);
When I run the JSON.decode line, I get this error:
JSONParseError: Unexpected c encountered
I have tried to find out what I am doing wrong, but Google Search didn't seem to help. I have tried different and basic JSON files to ensure it isn't my file.
json_file is a Class, rather than an instance. You should just need to pass a new instance of json_file to the decoder:
var jsonObj:Object = JSON.decode(new json_file());
It turns out I read the API wrong. The decode function needs a string, not a class. Here was my solution:
var bytes:ByteArray = new json_file();
var json:String = bytes.readUTFBytes(bytes.length);
var jsonObj:Object = JSON.decode(json);

I was trying to use the method found here (see most up-voted answer):
Google Apps Script Fastest way to find a row?
I currently use this while it does work I wanted to try the above linked method yet when I replace the below code
function AutoPopulate (evalue)
{
//uses google drive file irretator reads in JSON file and parses it to a Javascript object that we can work with
var iter = DriveApp.getFilesByName("units.json");
// iterate through all the files named units.json
while (iter.hasNext()) {
// define a File object variable and set the Media Tyep
var file = iter.next();
var jsonFile = file.getBlob().getDataAsString();
// log the contents of the file
//Logger.log(jsonFile);
}
var UnitDatabase = JSON.parse(jsonFile);
//Logger.log(UnitDatabase);
//Logger.log(UnitDatabase[1027]);
return UnitDatabase[evalue];
}
WITH THIS CODE:
function AutoPopulate (evalue)
{
//this method did not work for me but should have according to stackflow answer linked above I am trying to understand why or how I can find out why it may have thrown an error
var jsonFile = DriveApp.getFilesByName("units.json").next(),
UnitDatabase = UnitDatabase.getBlob().getDataAsString();
return UnitDatabase[evalue];
}
I get an error in the excecution indicating that there is a % at postion 0 in the JSON, between the methods I dont alter the JSON file in anyway so I dont understand why does the top method work but the bottom one does not?
For further information the idea behind the code is that I have a list of Unit numbers and model numbers that are in a spreadsheet. I then convert this to a JSON file, this however is only done when a new unit is added to the fleet. As I learned one can parse a whole JSON file into a javascript object which makes working with the data set much faster. This javascript object is used so that when a user enters a UNIT# the MODEL# is auto populated based on the JSON file.
I cannot share the JSON file as it contains client information.
Your code does not work for two reasons:
You have a typo in the line UnitDatabase = UnitDatabase.getBlob()... - it should be UnitDatabase = jsonFile.getBlob()...
If you want to retrieve a nested object from a json file - you need to parse the JSOn - otherwise it is considered a string and you can not access the nested structure
Modified working code:
function AutoPopulate2 (evalue)
{
var jsonFile = DriveApp.getFilesByName("units.json").next();
var UnitDatabase = JSON.parse(jsonFile.getBlob().getDataAsString());
return UnitDatabase[evalue];
}
Mind that this code will only work if you have a "units.json" file on your drive and if evalue is a valid 1st-level nested object of this json.
I am trying to use the Kairos API for Facial Recognition in my air app. After i send the image, kairos returns the following JSON:
{"images":[{"transaction":{"status":"failure","topLeftX":106,"topLeftY":126,"gallery_name":"Faces","eyeDistance":42,"height":98,"width":98,"face_id":1,"quality":-1.53973,"message":"No match found"}}],"uploaded_image_url":"https:\/\/kairos-east-id-images.s3.amazonaws.com\/prod\/c6d565457\/recognize\/Faces\/d2b1142f2134232349ewer8acb825c87e909f299ab1_5a234XXXXXX.jpg?X-Amz-Content-Sha246=UNSIGNED-PAYLOAD&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=XXXXXXXXXXXXXX-east-1%2Fs3%2XXXX_request&X-Amz-Date=2017122rrtdfg158Z&X-Amz-SignedHeaders=host&X-Amz-Expires=XXXX&X-Amz-Signature=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"}
I need to access the values of "topLeftX", "topLeftY" and "message" but no matter what i try it doesn't seem to work. I have been searching around for about an hour. I have tried both native JSON parser and ascorelib JSON parser.
I tried the following:
var rawData:Object = JSON.decode(e.target.data);
for ( var object:Object in rawData ){
trace(object.transaction);
}
I get this error:
Property transaction not found on String and there is no default value.
I tried with different property names but I get the same error. I have tried sever other methods as well. Such as,
rawData["transaction"][0]["topLeftX"]
It doesnt work.
Any help is greatly appreciated.
I do not have a decode function on JSON. Just a JSON.parse and a JSON.stringify however what should work for you is this.
var jsonObj = JSON.parse(yourdata); // or JSON.decode if you AS version is older
for ( var i = 0 ; i < jsonObj.images.length ; i++ ){
trace(jsonObj.images[i].transaction.status);
}
I am new to Scala and MongoDB. I am writing a Scala program to read JSON string (it can be nested json string also) and insert the same to Mongo DB.
I tried below few things but its not working.
1) Tried to create an Document for the JSON string as below:
var document = (DBObject) JSON.parse(jsonString)
but getting the error
"value JSON is not member of object com.mongodb.DBObject".
2) Also tried with bson.Document as below but still can get it working
var myDoc = (Document.parse(schemajson))
Can anyone help me out on this? Please let me know if my approach is correct. If not the please do let me know what all things I need to do.
adding code:
val hadoopRDD = sc.textFile(data_file).foreach(line =>
{
data_array.clear
line.split("\t").foreach(word => data_array += word)
println(data_array)
var final_json = (schemajson.format(data_array: _*))
var document = (DBObject) JSON.parse(jsonString)
in above code final_json is the string having Json string like {"name": xyz, "age": 22}
I found the answer and below is the solution which worked for me.
I was simply using
var document = (DBObject) JSON.parse(jsonString)
which was causing error.
Instead we need to provide asInstanceOf[DBObject] which worked in my case
val dbObject: DBObject = JSON.parse(final_json_str).asInstanceOf[DBObject]
I have a JSON file that contains what I believe to be a correct JSON string:
{"title": "exampleTitle", "tipTitle": "exampleTipTitle", "tip": "exampleTip"}
I'm trying to parse said file and take out the 3 values then store them in variables, however currently, it parses each individual character as a separate object, therefore:
JSONobj[1] = "
and so on. Assuming that currentLocation = the directory location of the json file.
Code
var jsonLocation = currentLocation + "json.txt";
var request = new XMLHttpRequest();
request.open("GET", jsonLocation, false);
request.send(null);
var returnValue = request.responseText;
var JSONobj = JSON.parse(JSON.stringify(returnValue));
var headerTitle = JSONobj[0];
A few clarifications, the stringify is in because it was throwing an unexpected token error. I've tried changing the file tile to .json instead but that also makes no difference. "It also gives off a XMLHttpRequest on the main thread is deprecated" but I'm not particularly sure how to solve that issue. Any help would be appreciated.
var returnValue = request.responseText;
Here returnValue is a string of JSON.
"{\"title\": \"exampleTitle\", \"tipTitle\": \"exampleTipTitle\", \"tip\": \"exampleTip\"}
var JSONobj = JSON.parse(JSON.stringify(returnValue));
Here you convert the string of JSON to JSON. So you have a JSON string representing a string, and that string is a representation of a data structure in JSON.
"\"{\\"title\\": \\"exampleTitle\\", \\"tipTitle\\": \\"exampleTipTitle\\", \\"tip\\": \\"exampleTip\\"}"
Then you parse it and convert it back to the original string of JSON.
"{\"title\": \"exampleTitle\", \"tipTitle\": \"exampleTipTitle\", \"tip\": \"exampleTip\"}
So you end up back where you start.
Just don't use JSON.stringify here, and you'll convert your JSON to a JavaScript object:
var javascript_object = JSON.parse(returnValue);
Then you have an object, but it doesn't have a 0 property so it doesn't make sense to access it with javascript_object[0]. The properties have names, such as javascript_object.title.
Your JSON doesn't describe an array, so indexing into it with an index like 0 doesn't make sense. Your JSON describes an object, which will have properties with the names title, tipTitle, and tip.
Additionally, you're overdoing your parsing: You just want to parse, not stringify (which is the opposite of parsing):
var JSONobj = JSON.parse(returnValue);
So:
var JSONobj = JSON.parse(returnValue);
var headerTitle = JSONobj.title;
console.log(headerTitle); // "exampleTitle"
Side note: By the time you've assigned it to the variable you've called JSONobj, it isn't JSON anymore, it's just a normal JavaScript object, so that name is a bit misleading. If you're writing source code, and you're not dealing with a string, you're not dealing with JSON anymore. :-)
I am running into an error parsing a json string with JSON.parse(...)
var str:String= '[{"AA":"A1", "BB":"32"}, {"AA":"A2", "BB":"12"}, {"AA":"A3", "BB":"14"}]';
var propertySets:Object = JSON.parse(str);
I can tell that I am getting the syntax wrong with constructing the JSON string but I have tried quite a few things before giving up. Any help with how to deal with collections would be great.
The following simple case works for me
var str:String= '{"test":"line1"}';
var propertySets:Object = JSON.parse(str);
Thank you
The syntax in the JSON string is correct. The way it is formatted will return an Array instance from JSON.parse(). The following code works for me:
var str:String = '[{"AA":"A1", "BB":"32"}, {"AA":"A2", "BB":"12"}, {"AA":"A3", "BB":"14"}]';
var propertySets:Array = JSON.parse(str) as Array;
trace(propertySets[0].AA); // prints "A1"
trace(propertySets[0].BB); // prints "32"
Shot in the dark since I don't know actionscript, but try wrapping the array in an object
var str:String= '{"objectArray":[{"AA":"A1", "BB":"32"}, {"AA":"A2", "BB":"12"}, {"AA":"A3","BB":"14"}]}';
