I am able to use sObject to put an Attachment onto one of my records. The problem is that SF is not recognizing the file as a PDF but as a generic file.
const base64data = await new Buffer.from(pdfBuffer).toString('base64');
try {
await conn.sobject('Attachment').create({
ParentId: filename,
Name: resumeFileName,
Body: base64data,
ContentType: fileType,
Description: 'Resume Attachment',
});
} catch (e) {
console.log('Attachment Error', e);
}
When I look at the attachments of my record, the file does not have all of the options that a PDF file has (only download and delete)
Thanks in advance!
Turns out in order for Salesforce to recognize the pdf correctly you need to have the content type set to application/pdf AND the name of the file must include the .pdf extension. This worked for me:
(async () => {
const jsforce = require('jsforce');
const fs = require('fs');
var conn = new jsforce.Connection({
instanceUrl : '...',
accessToken : '...'
});
const pdfData = fs.readFileSync('./test.pdf').toString('base64');
try {
await conn.sobject('Attachment').create({
ParentId: '0012300000RWedX',
Name: 'My Test PDF.pdf', // <= Turns out the name has to have .pdf
Body: pdfData,
ContentType: 'application/pdf',
Description: 'Testing PDF Attachment',
});
} catch(err) {
console.error(err);
}
})();

I got this data from backend when try to get a pdf file:
`%PDF-1.7 %���� 5 0 obj <</Filter/FlateDecode/Length 823>>stream x���MS�0���{l���)&���#CCK'!%�ӿߕmb���;�y�Ҿ��K��H�����aN��q��%�Iz&#�i�T

How can REACT read and open this as pdf file in a new tab?
NOTE: I'm able to see the PDF file content in postman when call backend endpoint.
I tried this:
Backend controller (Nestjs):
#Get('/getPDF/:uuid')
async getFile(
#Param('uuid') uuid: string,
#Response({ passthrough: true }) res,
): Promise<StreamableFile> {
const resp = await this.service.downloadPDF(uuid);
if (!resp) {
return null;
}
res.header('Content-Type', `application/pdf`);
res.header('Content-Disposition', `attachment; filename="${resp.fileName}`);
return new StreamableFile(resp.buffer); // resp.buffer === Uint8Array
}
Frontend (REACT):
This will call backend api to get pdf file:
getPDF(uuid: string): Promise<AxiosResponse<Blob>> {
return this.httpClient.get(`${this.apiUrlPath}/getPDF/${uuid}`, {
responseType: 'blob',
});
}
This was supposed to render the pdf file
const response = await api.getPDF(uuid);
window.open(URL.createObjectURL(response.data));
I got this error:
TypeError: Failed to execute 'createObjectURL' on 'URL': Overload resolution failed.
UPDATED
Change AxiosResponse type from Blob to ArrayBuffer and create a new Blob from that buffer, solves the issue
This works:
getPDF(uuid: string): Promise<AxiosResponse<ArrayBuffer>> {
return this.httpClient.get(`${this.apiUrlPath}/getPDF/${uuid}`, {
responseType: 'arraybuffer',
});
}
const response = await api.getPDF(uuid);
const blob = new Blob([response.data], { type: "application/pdf" });
window.open(URL.createObjectURL(blob));
Thanks amir sarfar
Try passing a blob to createObjectURL:
const response = await api.getPDF(uuid);
const blob = new Blob([response.data], { type: "application/pdf" });
window.open(URL.createObjectURL(blob));
I'm trying to use Nodemailer for this, but I can't use an attachment in the input, or I don't know how
https://nodemailer.com/message/attachments/
please help, anything is helpful for me
postuler.js
let details = {
name: name.value,
prenom: prenom.value,
email: email.value,
telephone: telephone.value,
cv: cv.file,
profil: profil.value,
motivation: motivation.value
};
let response = await fetch("http://localhost:5000/postuler", {
method: "POST",
headers: {
"Content-Type": "application/json;charset=utf-8",
},
body: JSON.stringify(details),
});
server.js
router.post("/postuler", (req, res) => {
const name = req.body.name;
const prenom = req.body.prenom

attachments: [
{ // use URL as an attachment
filename: cv.originalname,
contentType: 'application/pdf',
path: cv.path
},
]
};
You tring to send req.file.path as an attachment.
Nodemailer get files as zip , csv,pdf and ect...
Req.file.path it's tricky because the nodemailer don't no where the path is .
Try to zip or save your files in to one file in some folder (you can use fs or js-zip modules) and than give the path of the file as an path in the attachment object.
Thanks in advance for taking a look. I am working on being able to download a zip file from react through a django api request. I am able to click on my pop up that downloads the zip file, but when I double click on the zip file to open, I get this error: "Unable to expand file_name.zip. It is an unsupported format" My response with the zip file seems to be passing correctly to the front end, so I am thinking it may be something wrong with the react code when making the "blob"? Thanks again.
Django code:
class DownloadZip(APIView):
def post(self, request, format=None):
# information to find file to create zip
profile_name = request.data["profile"]
profile_year = request.data["year"]
# file path to create zips from
path = str(Path(__file__).parent.resolve())
zip_dir = shutil.make_archive(profile_name + profile_year, "zip", path + "/" + profile_name + profile_year)
s = io.StringIO(zip_dir)
response = HttpResponse(s, content_type = "application/zip")
zip_name = profile_name + profile_year + ".zip"
response["Content-Disposition"] = f"attachment; filename={zip_name}"
return response
React code:
downloadZip = async () => {
const params = {
profile: this.state.profileName,
year: this.state.year,
};
axios({
url: `${serverUrl}/download_zip`,
method: "post",
data: params
}).then(
(res) => {
const url = window.URL.createObjectURL(new Blob([res.data],{type:'application/zip'}));
const link = document.createElement('a');
link.href = url;
link.setAttribute('download', 'file.zip');
document.body.appendChild(link);
link.click();
link.parentNode.removeChild(link);
},
(error) => {
console.log(error);
});
}
I did do a fellow commentor's suggestion, and updated to get route with query params, but am having the same issue. I can double click on the zip link on the web browser but a pop up appears "Unable to expand filename.zip. It is an unsupported format"
Please try adding {responseType: 'arraybuffer'}. I also had the same problem but after adding this {responseType: 'arraybuffer'}. I am getting correct file.
downloadZip = async () => {
const params = {
profile: this.state.profileName,
year: this.state.year,
};
axios.post(
`${serverUrl}/download_zip`,
params,
{
responseType: 'arraybuffer'
}
).then(
(res) => {
const url = window.URL.createObjectURL(new Blob([res.data],{type:'application/zip'}));
const link = document.createElement('a');
link.href = url;
link.setAttribute('download', 'file.zip');
document.body.appendChild(link);
link.click();
link.parentNode.removeChild(link);
},
(error) => {
console.log(error);
});

I want to retrieve list of images in one go from Amazon S3 based on image URL.
Currently I am able to fetch single image using the following code:-
AWS.config.update({
accessKeyId: accessKeyId,
secretAccessKey: secretAccessKey
});
AWS.config.region = region;
var bucketInstance = new AWS.S3();
var params = {
Bucket: bucketName,
Key: awsImgUrl
}
bucketInstance.getObject(params, function (err, file) {
if (file) {
var dataSrc = "data:" + file.ContentType + ";base64," + EncodeData(file.Body);
callbackSuccess(dataSrc);
} else {
callbackSuccess("Error");
}
});
EncodeData = function (data) {
var str = data.reduce(function (a, b) { return a + String.fromCharCode(b) }, '');
return btoa(str).replace(/.{76}(?=.)/g, '$&\n');
}
In my scenario I have multiple S3 image url like awsImgUrl1, awsImgUrl2..awsImgUrln.
How to fetch it in one go instead of one by one?
You cannot get more than one image per api call with S3. You can however make multiple calls in parallel.
Using promises this is straightforward.
var bucketInstance = new AWS.S3();
var imageKeys = [ awsImgUrl1, awsImgUrl2, awsImgUrl3];
var promisesOfS3Objects = imageKeys.map(function(key) {
return bucketInstance.getObject({
Bucket: bucketName,
Key: key
}).promise()
.then(function (file) {
return "data:" + file.ContentType + ";base64," + EncodeData(file.Body);
})
})
Promise.all(promisesOfS3Objects)
.then(callbackSuccess) // callbackSuccess is called with an array of string
.catch(function() { callbackSuccess("Error") })
You can change the way you upload the image data. Instead of uploading a single image, upload one document containing multiple image datas.
const addImageBlock = () => {
var photoBlock = [
{
imageId: 'id',
type: 'png',
body: 'data:image/png;base64,iVBORw0K...'
},
{
imageId: 'id2',
type: 'png',
body: 'data:image/png;base64,iVBORw0K...'
},
{
imageId: 'id3',
type: 'png',
body: 'data:image/png;base64,iVBORw0K...'
},
{
imageId: 'id4',
type: 'png',
body: 'data:image/png;base64,iVBORw0K...'
}
//...ect
];
s3.upload({
Key: photoBlockId + '.json',
Body: photoBlock,
ACL: 'public-read'
}, function(err, data) {
if (err) {
return alert('There was an error', err.message);
}
});
}
Then when you receive this data with one s3 call, you can loop through and render the images on the frontend,
getObject(params, function (err, file) {
imageArr = [];
if (file) {
JSON.parse(file.toString()).map((image) => {
var image = new Image();
image.src = image.body;
imageArr.push(image)
})
callbackSuccess(imageArr);
}
else {
callbackSuccess("Error");
}
});
AWS SDK does not have any method to read multiple files as once and same with console, you can not download multiple files at once.
they have only GetObject method do read a object in bucket by key only.
so in your case you have to read one by one with their key name only if you already have key names as list..
you can get summary of objects in bucket if you would like to get list of objects then put a loop to download all files.
My Angular 1 application saves files to S3 and allows for a wide variety of files types.
When I retrieve the objects I use the following code:
export function show(req, res) {
const s3 = new aws.S3();
const s3Params = {
Bucket: S3_BUCKET,
Key: req.query.key + ''
};
res.attachment(req.query.key + '');
var fileStream = s3.getObject(s3Params).createReadStream();
fileStream.pipe(res);
}
I would like to open the received file on the client in a new window (just like on the AWS console) but I can't figure out how to go about it.
For example on the client side does not work at all:
.then(
(data) => {
var file = new Blob([data], {type: 'application/pdf'});
var fileURL = URL.createObjectURL(file);
window.open(fileURL);
}
)
I really don't understand how the concept of data streams works.
If you don't have to download pdf, you may open it directly from s3.
s3client.getResourceUrl("your-bucket", "some-path/some-key.jpg");
This will return you url to the file.
So you need code like:
export function show(req, res) {
this.s3client = new aws.S3({
accessKeyId: options.accessKeyId,
secretAccessKey: options.secretAccessKey,
region: options.region
})
let resourceUrl = s3client.getResourceUrl(S3_BUCKET, req.query.key + '');
window.open(resourceUrl, '_blank');
}
I'm sorry, can't test it right now, but try. Should work.
All I had to do was get a signedUrl for the resource for this to work much simpler than what I was trying to do.
export function show(req, res) {
const s3 = new aws.S3();
const s3Params = {
Bucket: S3_BUCKET,
Key: req.query.key + ''
};
s3.getSignedUrl('getObject', s3Params, (err, data) => {
if (err) {
console.log(err);
return res.end();
}
const returnData = {
signedRequest: data,
};
res.write(JSON.stringify(returnData));
res.end();
});
}
and on the client all I have to do is open the link in a new tab:
openDoc(doc) {
this.$http()
.then(
(data) => {
this.$window.open(data.data.signedRequest, '_blank')
}
)
.catch(
(err) => {
this.Notification.error('failed to download attachment');
}
)
}
