I have:
Raw xml filled by a select query.This xml transformed into a HL7
message
One of the tags of this xml represents a clob column from a table in
the database
I mapped this data (from edit transformer section) as a variable.
Now I am trying to convert this variable into a base64 string then
replace it in my transformed hl7 message.
5.I tried this conversion on a destination channel which is a javascript writer.
I read and tried several conversion methods like
Packages.org.apache.commons.codec.binary.Base64.encodeBase64String();
I have got only error messages like :
EvaluatorException: Can't find method org.apache.commons.codec.binary.Base64.encodeBase64String(java.lang.String);
Code piece:
var ads=$('V_REPORT_CLOB');
var encoded = Packages.org.apache.commons.codec.binary.Base64.encodeBase64String(ads.toString());
It is pretty clear that I am a newbie on that.How can I manage to do this conversion ?
Here is what I use for Base64 encoding a string with your var substituted.
//Encode Base 64//
var ads = $('V_REPORT_CLOB');
var adsLength = ads.length;
var base64Bytes = [];
for(i = 0; i < adsLength;i++){
base64Bytes.push(ads.charCodeAt(i));
}
var encodedData = FileUtil.encode(base64Bytes);

I've been given string data (stored in a database) where the originator read binary tiff files as a string using something like (they actually used the VB FileSystemObject):
var txt = File.ReadAllText(#"c:\some_image.tiff");
I need to re-create the original tiff files. I've tried looping through all encodings with:
var txt = File.ReadAllText(#"c:\test\some_image.tiff");
var encodings = Encoding.GetEncodings();
for (var i = 0; i < encodings.Length; i++)
{
File.WriteAllBytes(#"c:\test\some_image_" + i + ".tiff", encodings[i].GetEncoding().GetBytes(txt));
}
but to no avail.
I'm using a json file to store my data and I need to show some of it on the screen.
For example, when I make a simple text widget and use this string:
Text("a\u2081")
It shows "a" with a subscripted "1".
The problem is that when I load it from a json file it just shows "a\u2081".
This is how I load the data:
var myData = await rootBundle.loadString("data/my_data.json");
var data = await json.decode(myData.toString());
I'm storing the values in objects:
Text(TestReport[i].text) // where TestReport[i].text = "a\u2081"
Is there a way how to show the subscript?
I have the following G.A.S script to email a google sheet as a pdf attachment.
var spreadsheet = SpreadsheetApp.getActive();
var subject = spreadsheet.getRange("U1:U1").getValues();
var emailTo = spreadsheet.getRange("V1:V1").getValues();
var message = spreadsheet.getRange("W1:W1").getValues();
var pdf = DriveApp.getFileById(spreadsheet.getId()).getAs('application/pdf').getBytes();
var attach = {fileName:subject,content:pdf, mimeType:'application/pdf'};
MailApp.sendEmail(emailTo, subject, message, {attachments:[attach]});
The above code works well except that the file attached to the email message has a bizarre name like "[Ljava.lang.Object_#4e63998c" with no ".pdf" extension!
I am looking for a way to set a name for the pdf file before being attached to the email. The file name should equal the "subject" variable.
Thanks in advance.

Values retrieved by getValues() is 2 dimensional array. I think that the filename becomes such string because the array is used as the filename. Please retrieve the element from the array and try again. So could you please modify as follows?
From :
var attach = {fileName:subject,content:pdf, mimeType:'application/pdf'};
To :
var attach = {fileName:subject[0][0],content:pdf, mimeType:'application/pdf'};
You can also use the following modification. In this case, getValue() can retrieve the value as a string from the cell "U1".
From :
var subject = spreadsheet.getRange("U1:U1").getValues();
To :
var subject = spreadsheet.getRange("U1:U1").getValue();
Reference :
getValue()
getValues()
If this was not what you want, please tell me. I would like to think of other solutions.
I'm a bit late, but another way to solve this problem might be:
var spreadsheet = SpreadsheetApp.getActive();
var subject = spreadsheet.getRange("U1:U1").getValues();
var emailTo = spreadsheet.getRange("V1:V1").getValues();
var message = spreadsheet.getRange("W1:W1").getValues();
var pdf = DriveApp.getFileById(spreadsheet.getId())
.getAs('application/pdf')
.getBlob()
.setName(subject);
MailApp.sendEmail(emailTo, subject, message, {attachments:[pdf]});
The Blob class has a setName method https://developers.google.com/apps-script/reference/base/blob#setName(String), that can be chained into a Blob object (which is the result of getBlob())
After that you just need to add the Blob object inside attachments array of function MailApp.sendEmail
I am trying to make a JavaScript function with package crypto-js to decode AES (CBC mode).
I input the data in an online decoding tool and it decrypted correctly, so I am sure the following data is correct, but I just can't reproduce it by JavaScript.
Here is the online decrypting (so I'm sure the data, key, iv are correct): http://aes.online-domain-tools.com/link/deb718giF4dUxZylq/
My code with crypto-js#3.1.8:
// data, key, iv are all Hex
var data = "bd6e0a73147a2c224c7c20346d0e9a138b744a5d94463cdff6dbb965055f974f097104399d2c40af2f0ac667f3857e70e9703bf27f6411f7e97c3449e8921f3c98e665914689b4b77b5bbcc8d8bc319e680eb89eedb1c25178923ae57fb3fb476755d6009f1aed88fffcb9b2ed3b4cf6f23d9c4c56da1dde6619e45a8d6f06412853ae1941cf554b6824112a913750a7485ed67fb38b950411310410de998f2597c2fcc81a305b0df369f54b75426176";
var key = 'befce5c6da98837ea421811c832817ae';
var iv = "a884a7edd5d06a48d6da9ad11fd36a75";
// transfer Hex to WordArray
var _data = CryptoJS.enc.Hex.parse(data);
var base64_data = _data.toString(CryptoJS.enc.Base64);
var _key = CryptoJS.enc.Hex.parse(key);
var _iv = CryptoJS.enc.Hex.parse(iv);
decrypted = CryptoJS.AES.decrypt(
base64_data, // pass base64
_key, // pass WordArray
{iv: _iv, // pass WordArray
mode: CryptoJS.mode.CBC,
padding: CryptoJS.pad.ZeroPadding
})
console.log(decrypted.toString(CryptoJS.enc.Utf8));
// out put fail to match Utf8
It output Error: Malformed UTF-8 data
The decoded string should be: (the link is not important)

Any hint is appreciated. Thank you!
I know it has been a while since you asked the question but I will respond just so the next person does not stumble upon an unanswered question.
Your code works fine, it decrypts AES.CBC encrypted data correct, the problem lies with your input data.
Your encrypted data string should have looked like:
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
for this example to work correctly.
The key you used is not a hex string but a text string. Your online example is no longer valid but I figured it out after a couple of tries.
If change the following line:
var _key = CryptoJS.enc.Hex.parse(key);
to:
var _key = CryptoJS.enc.Utf8.parse(key);
Your code example will work fine with your original data string.
When you decrypted the text on http://aes.online-domain-tools.com/ you probably had the plaintext textbox selected instead of hex for your key input.
I'm using Papa.unparse() to convert a JSON object to csv then downloading the file. The method fails with:
"allocation size overflow papaparse.min.js:6:1580"
This happens in firefox when there's > than 500,000 items to unparse in the JSON array.
The Papa.parse() method allows you to stream data from a file. Is there any similar approach you can take for Papa.unparse()?
You don't need PapaParse to do this.
The allocation size overflow problem is from converting your 500,000 rows into 500,000 strings and concatenating them together to form one massive string to create the CSV file with. JavaScript creates a new String when you concatenate one or more together, and eventually you run out of memory and crash.
The solution is to use TextEncoder to encode your strings into utf-8 (or whatever you need) ArrayBuffers, push each one into a giant array, and then use that array to create your file.
Here's some rough code for how you might do that:
var textEncoder = new TextEncoder("utf-8");
var headers = ["header1","header2","header3"];
var row1 = ["column1-1","column1-2","column1-3"];
var row2 = ["column2-1","column-2-2","column2-3"];
var data = [headers,row1,row2];
var arrayBuffers = [];
var csvString = '';
var encodedString = null;
var file = null;
for(var x=0;x<data.length;x++){
csvString = data[x].join(",").concat('\r\n');
encodedString = textEncoder.encode(csvString);
arrayBuffers.push(encodedString);
}
file = new File(arrayBuffers,"yourCsvFile.csv",{ type: "text/csv" });
I use text-encoding for a TextEncoder polyfill, and presumably if you're trying to Papa.unparse you've got FileAPI already.
