ASP.NET Core How to pass an IEnumerable String as a Variable in JavaScript

I would like to pass the To Mailbox Address as a parameter with multiple addresses using MimeKit to send a message.
If I edit the controller action to include a string with 2 email addresses:
var message = new Message(new string[] { "address1#gmail.com","address2#gmail.com" }, eMailSubject, eMailContent, null);
the message will be sent to both recipients address1#gmail.com and address2#gmail.com.
However If I try to pass the parameter string eMailTo from the function email_valueChanged(e), I get the errors:
$exception {“Invalid addr-spec token at offset 0”}
x "\"address1#gmail.com\",\"address2#gmail.com\""
Is there a way to pass the eMailTo parameter for the IActionResult SendMessage within the javascript? Note that to is an IEnumerable string:
public Message(IEnumerable<string> to, string subject, string content, IFormFileCollection attachments)
I have also tried to pass the eMailTo parameter as an array with no luck.
Below are the details:
Function to send email from popup:
function showInfo(data) { location.href = '#Url.Action("SendMessage", "EMail")?eMailTo=' + eMailToAddress +'&eMailSubject=' + eMailSubject + '&eMailContent=' + eMailContent;}
<script>
let eMailToAddress = -1;
let eMailSubject = -1;
let eMailContent = -1;
function email_valueChanged(e) {
eMailToAddress = '"address1#gmail.com","address2#gmail.com"';
console.log("eMailToAddress = " + eMailToAddress);
}
</script>

ASP.Net Core 3 Posting JSON array to controller

I´m having issues passing an array of JSON objects to an MVC controller in ASP.Net core 3. The JSON object is built from a CSV file and passed through an AJAX call. The correct action is called but the object received is always null.
JS:
async function updateData(){
var obj = await getData();
$.ajax({
type: "POST",
contentType: "application/json",
url: "/admin/metric/Update",
data: obj,
dataType: 'json',
success: function (data) {
console.log("SUCCESS : ", data);
},
error: function (e) {
console.log("ERROR : ", e);
}
});
}
async function getData(){
var metric = {};
var metrics = [];
var response = await fetch('https://bloburi.net/source/file.csv');
var data = await response.text();
var table = data.split('\n').slice(1);
table.forEach(row => {
var columns = row.split(',');
metric["FirstName"] = columns[0];
metric["LastName"] = columns[1];
metric["Email"] = columns[2];
metric["AverageHandleTime"] = columns[3];
metric["AverageFollowUp"] = columns[4];
metric["AverageHold"] = columns[5];
metric["Date"] = columns[6];
metrics.push(JSON.stringify(metric));
});
console.log(metrics);
return metrics;
}
Models:
public class MetricBase
{
[Required]
public string Date { get; set; }
public double AverageHandleTime { get; set; }
public double AverageHold { get; set; }
public double AverageFollowUp { get; set; }
public string Email { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
}
public class MetricModel
{
public IEnumerable<MetricBase> MetricBase { get; set; }
}
Controller:
[HttpPost]
public IActionResult Update([FromBody]MetricModel obj)
{
return Json(new { obj });
}
I think the issue may be on how I'm deffining the class that is receiving the JSON, but I've tried multiple things like deffining MetricBase as a List<> or straight up as an array in MetricModel, but it doesn't seem to work.
Any help is appreciated!

You adding the stringify item inside array via code
metrics.push(JSON.stringify(metric));
instead of stringify the whole array. Change the line to
metrics.push(metric);
and data: obj, to
data: JSON.stringify(obj),.
With the mentioned change, the $.ajax sends the whole array. Also change the action to
public IActionResult Update([FromBody]IEnumerable<MetricBase> obj)

Values null when I make a simple post request to my .net controller from angular

This used to be a 415 error question.
Now it is a a receiving null values on the server side question.
I am having difficulty trying to get my values in the object myMessage over to the server side.
I have so far tried to add JSON.stringify to newMessage which is being console.logged in the service file.
I tried many ways to alter or make the object the way it would be recognized such as JSON.stringify() and creating a url ending with the correct parameters.
Sorry if it seems like I am dumping code below, but I have been working on this for a second day and don't understand why I can't do a simple post request with three parameters. One string, one int, and one datetime.
If anyone can see where I have gone wrong I would so appreciate it. I will be desperately waiting.

Please let me know if additional info is needed.

1) You need to set the Content-Type header to application/json.
2) stringify the message.
const headers = new HttpHeaders()
.set('Content-Type', 'application/json;charset=UTF-8')
let options = { headers : headers };
this.http.post(this.baseUrl + 'api/SlgCorpNotes/Edit', JSON.stringify(newMessage), options);

At your angular side update your method like this
updateMessage(message: any) {
console.log("at service")
console.log(message)
var newMessage = new CorpNotes(message['departments'], message['noteBody'], message['weeks'].weekEnding)
var Params = '?Department=' + message['departments'] + '&Note=' + message['noteBody'] + '&WeekEnding=' + message['weeks'].weekEnding
console.log(newMessage)
console.log(JSON.stringify(newMessage))
console.log(Params)
var item = {
"Departments": message["Departments"],
"Note": message["noteBody"],
"WeekEnding": message["weeks"]
}
return this.http.post(this.baseUrl + 'api/SlgCorpNotes/Edit', item).subscribe(res
=> {
console.log(res);
}, error => {
console.log(error);
});

AngularJS ngResource POST object is Null in C# Web API

My problem is that when I send a complete Javascript object to my Web API Controller I always get null values. Even though I have a complete object I need to specify each attribute and value as you can see below. How can I make Web API accept a ready made Javascript object and bind it correctly?
C# Web Api Controller:
[Route("addcredentials/{salesId}")]
[HttpPost]
public IHttpActionResult AddCredentials([FromUri] int salesId, [FromBody] ScriveCredentials credentials)
{
return Ok(credentials);
}
C# Credentials object:
public class Credentials
{
public string ClientIdentifier { get; set; }
public string ClientSecret { get; set; }
public string TokenIdentifier { get; set; }
public string TokenSecret { get; set; }
}
Javascript object passed to resource, saved as "result" further down:
{ClientIdentifier: "a", ClientSecret: "b", TokenIdentifier: "c", TokenSecret: "d"}
Resource method:
addCredentials: {
method: 'POST',
url: 'api/addcredentials/:userSalesId'
}
Usage that results in null values:
userResource.addCredentials({ userSalesId: user.SalesId }, { credentials: result}).$promise.then(function (data) {
console.log(data);
});
Payload for this request:
{"credentials":{"ClientIdentifier":"a","ClientSecret":"b","TokenIdentifier":"c","TokenSecret":"d"}}
Usage that works but seems overly complicated:
userResource.addCredentials({ userSalesId: user.SalesId }, { ClientIdentifier: result.ClientIdentifier, ClientSecret: result.ClientSecret, TokenIdentifier: result.TokenIdentifier, TokenSecret: result.TokenSecret }).$promise.then(function (data) {
console.log(data);
});
Request payload:
{"ClientIdentifier":"a","ClientSecret":"b","TokenIdentifier":"c","TokenSecret":"d"}
Update
Tried the following and it did not work either, null on all values:
addScriveCredentials: {
method: 'POST',
url: 'api/addcredentials/'
result.SalesId = user.SalesId;
userResource.addCredentials({}, { credentials: result }).$promise.then(function (data) {
console.log(data);
});
C#:
[Route("addcredentials")]
[HttpPost]
public IHttpActionResult Addcredentials(Credentials credentials)
{
return Ok(credentials);
}

I had done a sample earlier, hope the follwing code will help you to understand.
The Model.
using System.ComponentModel.DataAnnotations;
public class ProductModel
{
public ProductModel(int id, string name, string category, decimal price)

}
public int Id { get; set; }
[Required]
public string Name { get; set; }
[Required]
public string Category { get; set; }
[Required]
public decimal Price { get; set; }
}

You could pass one object as the body of the post message instead.
Add a class like this
public class addCredentialObj
{
public int salesId { get; set; }
public Credentials credentials { get; set; }
}
Modify your controller like this (The use of FromBody can be read here)
[Route("addcredentials")]
[HttpPost]
public IHttpActionResult AddCredentials([FromBody]addCredentialObj obj)
{
return Ok(credentials);
}
In the client you need to create a matching json object to the addCredentialObj class
var yourCredentials = {"ClientIdentifier":"a","ClientSecret":"b","TokenIdentifier":"c","TokenSecret":"d"};
var jsonData = {
salesId: yourId,
credentials: yourCredentials
};
And then in the $http request to the controller, stringify the json object
$http({
method: 'POST',
url: 'api/addcredentials',
headers: {
'Access-Control-Allow-Origin': '*',
'Content-Type': 'application/json'
},
data: JSON.stringify(jsonData),
});

Office Apps, how send copy of doc file with ajax to C# controller

hello i have this problem:
I have a addins for office(word);
I want to send a copy of current file (.docx) to C# controller, i have this code now, at this stage of the code i get a array of chars or somethis in the "yourfile", how ca i get a .docx file?
JavaScript
function sendFile() {
Office.context.document.getFileAsync("compressed",
{ sliceSize: 100000 },
function (result) {
if (result.status == Office.AsyncResultStatus.Succeeded) {
var myFile = result.value;
var state = {
file: myFile,
counter: 0,
sliceCount: myFile.sliceCount
};
getSlice(state);
}
});
}
function getSlice(state) {
state.file.getSliceAsync(state.counter, function (result) {
if (result.status == Office.AsyncResultStatus.Succeeded) {
sendSlice(result.value, state);
}
});
}
function myEncodeBase64(str)
{
return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g, function (match, p1) {
return String.fromCharCode('0x' + p1);
}));
}
function sendSlice(slice, state) {
var data = slice.data;
if (data) {
var fileData = myEncodeBase64(data);
var _url = '../../api/file';
useAjax(_url, 'Post', JSON.stringify(fileData), _contentType).done(function (data) {
writeData(data);
app.showNotification("Translation was successfully done!");
});
}
}
And the C# CONTROLLER:
public static string filemame = #"c:\yourfile";
[Route("file")]
[HttpPost]
public void getFile([FromBody] string data)
{
Base64ToFile(data,filemame);
}
public static void Base64ToFile(string base64String, string filename)
{
byte[] fileByteArray = Convert.FromBase64String(base64String);
// Instantiate FileStream to create a new file
System.IO.FileStream writeFileStream = new System.IO.FileStream(filename, System.IO.FileMode.Create, System.IO.FileAccess.Write);
// Write converted base64String to newly created file
writeFileStream.Write(fileByteArray, 0, fileByteArray.Length);
// Clean up / disposal
writeFileStream.Close();
}

Late to the party, but I'm adding the answer here nonetheless, in case someone else will need it at some later date.
Instead of using myEncodeBase64 you should use
var fileData = OSF.OUtil.encodeBase64(data);
It's a function that is part of the Office API, so you don't have to define anything else.

I have been struggling to construct a correct pptx serverside. Eventually this is what I came up with.
Javascript
function sendSlice(slice, state) {
var data = slice.data;
if (data) {
var isLastSlice = state.counter >= (state.sliceCount -1);
var ajaxData = {
isLastSlice: isLastSlice,
counter: state.counter,
documentData: btoa(data)
}
$.ajax({
url: "/api/Constructpptx", method: "POST", data: ajaxData, success: function (result) {
state.counter++;
if (isLastSlice) {
closeFile(state);
}
else {
getSlice(state);
}
}, error: function (xhr, status, error) {
}
});
}
}
And as an API backend I use this
C# ApiController
public class ConstructpptxController : ApiController
{
public static List<byte> Document { get; set; } = new List<byte>();
public string Post([FromBody]ConstructpptxPayload payload)
{
if (payload.counter == 0)
Document.Clear();
var payloadData = Convert.FromBase64String(payload.documentData);
var pptBytes = Encoding.UTF8.GetString(payloadData).Split(',').Select(byte.Parse).ToArray();
Document.AddRange(pptBytes);
if(payload.isLastSlice)
{
var path = #"C:/Some/Local/Path/Presentation.pptx";
var fileStream = new FileStream(path, FileMode.Create, FileAccess.ReadWrite);
fileStream.Write(Document.ToArray(), 0, Document.Count());
fileStream.Close();
Document.Clear();
}
return $"Counter: {payload.counter}, isLast: {payload.isLastSlice}, docLength: {Document.Count}";
}
}
public class ConstructpptxPayload
{
public bool isLastSlice { get; set; }
public int counter { get; set; }
public string documentData { get; set; }
}
Please note: only use this example as a quick starting point, as you don't want to save the bytes in a static List Document. Instead you want to make your webserver stateless.
