I have this package nodemailer used in Meteor.
After getting the emails, I would like to save the attachments using Meteor Files.
The problem is I don't know how. Can anyone provide a simple example for uploading files in server code. I tried uploading in the client and successful. But when i tried Files.insert() in server, it have "not a function" error.
Here is my code in server,
var mailparser = new MailParser({
streamAttachments: true
});
Fiber(function() {
var timeStamp = Math.floor(Date.now());
mailparser.on("attachment", function(attachment, mail){
... code here to upload
mailparser.on("end", Meteor.bindEnvironment(function (mail_object) {
.... some code here
}));
mailparser.write(data);
mailparser.end();
client.dele(msgnumber);
}).run();
Because insert function is for client side only, I used write() function of Files API. Here is the link,

The front end enables people to upload their photos, so i was sending the base64 to the server and working with it initially, but there are problems with firewall which blocks the request which contains base64. As an alternative solution I was trying to upload the image to azure blob get the file name and then send that to the server for processing where I generate a sas token for the blob validation and processing.
This works perfectly fine when I work locally and the front end connection works with #azure/storage-blob
and uploadBrowserData() when I send the arrayBuffer as the param
export const uploadSelfieToBlob = async arrayBuffer => {
try {
const blobURL = `https://${accountName}.blob.core.windows.net${sasString}`;
const blobServiceClient = new BlobServiceClient(blobURL, anonymousCredential);
const containerClient = blobServiceClient.getContainerClient(containerName);
let randomString = Math.random().toString(36).substring(7);
const blobName = `${randomString}_${new Date().getTime()}.jpg`;
const blockBlobClient = containerClient.getBlockBlobClient(blobName);
const uploadBlobResponse = await blockBlobClient.uploadBrowserData(arrayBuffer);
return { blobName, blobId: uploadBlobResponse.requestId };
} catch (error) {
console.log('error when uploading to blob', error);
throw new Error('Error Uploading the selfie to blob');
}
};
When I deploy this is not working, the front is deployed in the EastUs2 location and the local development location is different.
I thought the sasString generated for anonymous access had the timezone option so I generated 2 different one's one for local and one for hosted server with the same location selected.
Failed to send request to https://xxxx.blob.core.windows.net/contanainer-name/26pcie_1582087489288.jpg?sv=2019-02-02&ss=b&srt=c&sp=rwdlac&se=2023-09-11T07:57:29Z&st=2020-02-18T00:57:29Z&spr=https&sig=9IWhXo5i%2B951%2F8%2BTDqIY5MRXbumQasOnY4%2Bju%2BqF3gw%3D
What am I missing any lead would be helpful thanks
First, as mentioned in the comments there was an issue with the CORS Settings because of which you're getting the initial error.
AuthorizationResourceTypeMismatchThis
request is not authorized to perform this operation using this
resource type. RequestId:7ec96c83-101e-0001-4ef1-e63864000000
Time:2020-02-19T06:57:31.2867563Z
I looked up this error code here and then closely looked at your SAS URL.
One thing I noticed in your SAS URL is that you have set the signed resource type (srt) as c (container) and trying to upload the blob. If you look at the description of the kind of operations you can do using srt=c here, you will notice that blob related operations are not supported.
In order to perform blob related operations (like blob upload), you would need to set signed resource type value to o (for object).
Please regenerate your SAS Token and include signed resource type as object (you can also include container and/or service in there as well) and then your request should work. So essentially your srt in your SAS URL should be something like srt=o or srt=co or srt=sco.
I couldn't notice anything wrong with the code you mentioned about, but I have been using a different method to upload files to Azure Blog Storage using React, the method is exactly the same as in this blog article which works perfectly for me.

I have a simple service on Angular 2 and Typescript that requests Excel files to a server and then opens a download file dialogue for the user. However, as it is currently, the file becomes corrupt when downloaded.
When downloaded, it opens fine in OpenOffice and derivates, but throws a "File is Corrupt" error on Microsoft Excel, and asks if the user wants to recover as much as it can.
When Excel is prompted to recover the file, it does so successfully, and the recovered Excel has all rows and data that is expected for the Excel file. Comparing the recovered file against opening the file in OpenOffice and derivates evidence no outstanding differences.
The concrete Excel I am trying to download is generated with Apache POI in a microservice, then passed to the main backend and finally served to the frontend for the user to download. Both the backend and microservice are written in Java, through Spark Framework.
I made some tests on the backends, and concluded the problem is not the report generation nor the data transfer:
Asking the microservice to save the generated Excel in a file within the server and then opening such file (hereby file A) in Excel shows that file A is not corrupted.
Asking the main backend server to save the Excel file that it receives from the microservice in a file within itself and then opening such file in Excel (hereby file B) shows that file B is not corrupted.
Downloading both file A and file B through FileZilla from their respective servers yields completely uncorrupted files.
As such, I believe it is safe to assume the Excel becomes corrupted somewhere between the time the file is received on the frontend and the time the user downloads such file. Additionally, the Catalina logs do not evidence any error that might potentially be happening.
I have read several posts that deal with the issue, including a bug report (https://github.com/angular/angular/issues/14083) that included a workaround via XMLHTTPRequest. However, none of the workarounds detailed were successful in solving my issue.
Attached is the code I am using to both obtain the Excel file from the backend and serve it to the user. I am including both an XMLHTTPRequest and an Angular http call (within comments) since those are the two main ways I have been trying to make this work. Additionally, please do take into account the code has been altered to remove information I do not wish to make public.
download(body) {
let reply = Observable.create(observer => {
let xhr = new XMLHttpRequest();
xhr.open('POST', 'URL', true);
xhr.setRequestHeader('Content-type', 'application/json;charset=UTF-8');
xhr.setRequestHeader('Accept', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
xhr.setRequestHeader('Authorization', 'REDACTED');
xhr.responseType = 'blob';
xhr.onreadystatechange = function () {
if(xhr.readyState === 4) {
if(xhr.status === 200) {
var contentType = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet';
var blob = new Blob([xhr.response], { type: contentType });
observer.next(blob);
observer.complete();
}
else {
observer.error(xhr.response);
}
}
}
xhr.send(JSON.stringify(body));
});
return reply;
/*let headers = new Headers();
headers.set("Authorization", 'REDACTED');
headers.set("Accept", 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
let requestOptions :RequestOptions = new RequestOptions({headers: headers, responseType: ResponseContentType.Blob});
return this.http.post('URL', body, requestOptions);*/
}
Hereby is the code to prompt the user to download the Excel. It is currently made to work with the XMLHTTPRequest. Please do note that I have also attempted to download without resorting to FileSaver, with no luck.
downloadExcel(data) {
let body = {
/*REDACTED*/
}
this.service.download(body)
.subscribe(data => {
FileSaver.saveAs(data, "Excel.xlsx");
});
}
Hereby are the versions of the tools I am using:
NPM: 5.6.0
NodeJs: 8.11.3
Angular JS: ^6.1.0
Browsers used: Chrome, Firefox, Edge.
Any help on this issue would be appreciated. Any additional information you may need I will be happy to provide.
I think what you want is CSV format which open in Excel, update your sevice as follow:
You should tell Angular you are expecting a response of type blob (Binary Large Object) that is your Excel/Csv file.
Also make sure the URL/API on your server is set to accept content-type='text/csv'.
Here's an example with Angular 2.
#Injectable()
export class YourService {
constructor(private http: Http) {}
download() { //get file from the server
this.http.get("http://localhost/..", {
responseType: ResponseContentType.Blob,
headers: new Headers({'Content-Type', 'text/csv'})
}).subscribe(
response => {
var blob = new Blob([response.blob()], {type: 'text/csv'});
FileSaver.saveAs(blob, 'yourFileName.csv');
},
error => {
console.error('something went wrong');
}
);
}
}
Have you tried uploading/downloading your xls file as base64?
var encodedXLSToUpload = 'data:application/xls;base64,' + btoa(file);

In the dev environment for my React app, I have a set of public/private keys that I need to access an API. I'd like to ideally put these keys into their own file for gitignore purposes, but i'm not having luck with my code as shown below.
my helpers.jsx file is where the API data is called via lightweight AJAX add-on, and I have the actual keys in the require declarations area:
var API_KEY = require('./keys.jsx');
var PRIV_KEY = require('./keys.jsx');
Summarily, my keys.jsx file (stored in the same subfolder as the helpers.jsx) consists of the following:
module.exports = {
API_KEY:'myactualpublickey',
PRIV_KEY:'myactualprivatekey'
};
However, my app does not like this set up, as I get an "Failed to load resource: the server responded with a status of 401 (Unauthorized)” error message and the API call isn't successful because the necessary keys are not included.
When I replace the require('./keys.jsx'); in the helpers.jsx file with the actual keys, the API call works fine.
Any help or guidance would be most appreciated. Thanks.
You're exporting an object with properties called API_KEY and PRIV_KEY, so try this:
var API_KEY = require('./keys.jsx').API_KEY;
var PRIV_KEY = require('./keys.jsx').PRIV_KEY;
I have a game finished and I´m saving the scores in a database perfectly, only if I use webview+, if I change to canvas+ the save proccess is not working (and no errors).
I´m trying to save this data sending it to a php file connected to de database (as I said, is working using webview or webview+)
How would you do this using canvas+?
var http = new XMLHttpRequest();
var url = path+"getScores.php";
var params = "game=1&order=ASC";
http.open("POST", url, true);
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");
http.onreadystatechange = function() {
if(http.readyState == 4 && http.status == 200) {
alert(http.responseText);
}
}
http.send(params);
Please, try passing the parameters in the request URL using a GET (just in case). Also, try compiling a custom launcher in the cloud using the latest version (2.1.1). Actually, the JQuery errors should disappear by doing this.
And as Iker said, you can fix this with a custom launcher. I didn´t know about this thing but well, it´s working perfectly now, so if you have this problem, just try that and good luck.
I am sending a downloadable file from backend to AngularJS. Whenever a GET request (with some data as parameters) is made to the "/report" url, the server sends a file that I want to receive in AngularJS. Ideally, a browser should prompt user for saving/opening a file that server sends. So far I have done this:
$scope.getReport = function () {
console.log("getReport");
var report_url = '/report';
var some_data = "asdf";
$http({method:'GET', url:report_url, data=some_data})
.success(function(data) {
});
};
Now I am unable to figure out how to get the file that server sent me.
I created this fiddle for you http://jsfiddle.net/xMdQV/
Instead of making a get request and waiting for the server to return a file that you want to download
you could replace someData with your some_data
Tested on Chrome, Firefox and IE9.
