I'm working on project which can access all the pictures in g-mail.I've tried the G-mail API using node which can fetch all required attachments.But that requires to download the whole image.I can access the attachment id and message id using the API.Is there any way to generate the url of attachment (to view) so that i can provide a link to the required image from my project.
I actually found this related issue, Issue #134, and you may want to try the suggested solution.
You may fetch email attachments using this:
https://mail.google.com/mail/u/0/?ui=2&ik={ik_value}&view=att&th={message_id}&attid=0.{atachment_index}&disp=safe&zw
wherein, attachmment_index is just the index of the attachment. If there are 3 attachments and you want to get the 3rd file, the index value will be 3. This URL is a 302 header that acts like a link shortener for the download file. Opening this link will lead you to the attachment data
var ik = gmail.tracker.ik;
var id = gmail.get.email_id();
var aid = "1"; // gets the first attachment
var url = "https://mail.google.com/mail/u/0/?ui=2&ik=" + ik + "&view=att&th=" + id + "&attid=0." + aid + "&disp=safe&zw";
console.log(url);

I have a Java API endpoint that returns an excel (I am using content-disposition=Content-Disposition","attachment; filename=Audit.Report.xlsx).
I have another Angular-Node JS application that needs to consume this API and when the user clicks on a link, it should pull the excel and display a pop-up asking them the location to save the document. I am at a loss as to how I can do this. I tried doing the following on the server side though,
Server Code:
getAuditReport = function ( req, resp ) {
var numberOfMonths = req.query.numberOfMonths;
console.log('In first method ' + numberOfMonths);
var auditReportPromise = this.getAuditReportXlPromise ( numberOfMonths );
auditReportPromise.then ( function ( data ) {
resp.headers('Content-Disposition: attachment; filename="audit.report_'+ new Date() + '".xls"');
resp.ContentType = "application/vnd.ms-excel";
resp.status ( 200 ).send ( data );
} ).catch ( function ( err ) {
resp.status ( 500 ).send ( err );
} );
}
The getAuditReportXlPromise method returns a promise to invoke the get method of the Java API. On invoking this API via a browser, I get the excel content on the browser rather than a prompt requesting me to save the document somewhere.
Can someone suggest what's wrong here, and what I need to do on the client side for the click functionality to work.
Update 1:
Following is the code from the HTML
<a id='10051' href="{{url}}" target=_blank class="ok-white-text">
Download Report
</a>
Based on the duration the user selects, I'm building the URL - this is getting built correctly.
If your API provides the file using GET then you should be able to download the file in a simple way by just setting a link to that API (i.e. an anchor containing the link like Download).
In this scenario the browser will take over the download process (i.e. locating the folder to download to, if configured to do so).
If you want to process the file on client side, then you need to transfer it in a binary mode as suggested by multiple answer for this question.
To answer how I did manage to get around this,
Client Side:
In the component, I did the following - wrote a method on clicking the button that contains a window.open to the url - something like,
window.open("<path to the java api>", '_blank');
The link like I mentioned above was a java api that was already generating the excel file.
I am working with OpenAS2Server-1.3.3 library.
There sending a single document is working fine..
Now I wanted to modify it to send document with attachments, like we do with emails. In this scenario, all the decription work well, but signature verification failed (MIC is not matched)
This is how I am tring to send attachments with main doc:
Create a MimeMultipart and add two MimeBodyPart into it. (main document and the attachment)
Finally wrap the MimeMultipart within a MimeBodyPart (I am not sure this is the way to do this, but anyway Bouncycastle do not have API to sign MimeMultipart )
Could anyone tell me the correct way to sign a message with attachment ?
MimeBodyPart mainBody = new MimeBodyPart();
mainBody.setDataHandler(new DataHandler(byteSource));
MimeBodyPart attachemt1 = new MimeBodyPart();
attachemt1.attachFile("/home/user/Desktop/Test1.txt");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(mainBody);
multipart.addBodyPart(attachemt1);
MimeBodyPart body = new MimeBodyPart();
body.setContent(multipart);
body.setHeader("Content-Type", multipart.getContentType());
logger.info("--------------Attaching the file... Done");
I was able to get the issue and solution. I am just putting it here for anyone else who will try to do this kind of work.
I just dump the data that use for calculating MIC, at both sending side and receiving side. So the attached image will show the problem clearly.
So I added those header fields manually for all the attachments and main doc, at the sending side, as bellow.
mainBody.setHeader("Content-Type", "application/EDI-X12");
mainBody.setHeader("Content-Transfer-Encoding", "7bit");
Now it solved and "MIC is matched".
I am currently doing a POST to a Web Api method and am posting an array of objects. When I get to the method, my parameters are resolved properly, and I make a call to the DB and return a list of records.
I then take those records and convert them to a MemoryStream to be downloaded by the browser as an Excel spreasheet. From there, I create an HttpResponseMessage object and set properties so that the browser will recognize this response as a spreadsheet.
public HttpResponseMessage ExportSpreadsheet([FromBody]CustomWrapperClass request){
var result = new HttpResponseMessage();
var recordsFromDB = _service.GetRecords(request);
MemoryStream export = recordsFromDB.ToExcel(); //custom ToExcel() extension method
result.Content = new StreamContent(export);
result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");
result.Content.Headers.ContentDisposition.Name = "formName";
result.Content.Headers.ContentDisposition.FileName = "test.xlsx";
return result;
}
Instead of seeing the spreadsheet being downloaded, nothing seems to happen. When I check the developer tools (for any browser), I see the Response Headers below while the Response tab just shows binary data. Does anyone know what I might be missing here?
How are you doing your POST? It sounds like you might be trying to this via a javascript AJAX call, which cannot be done (https://stackoverflow.com/a/9970672/405180).
I would instead make this a GET request for starters, and use something like window.location="download.action?para1=value1....". Generally web api Post requests are made to create a file/entry, not retrieve one.
Alternatively, you could use a HTML Form with hidden elements corresponding to your query parameters, and use javascript to submit the form.
My javascript code looks like this
var query = window.location.search.replace('?','');
fetchContent(apiUrl + 'service/' + query + '?callback=?', function(data) {
$('.content').append(data).trigger('create');
});
I am using jQueryMobile, nodeJS for services and views. Also, using EJS templates to display data.
The problem is that I am not able to get value for variable query in the above code and hence the next following lines form up a parameter 'apiUrl/service/?callback=?' for fetchContent method which is a wrong URL for my service. The correct parameter for my fetchContent method should be 'apiUrl/service/1234?callback=?'.
Interesting thing is that this code works fine when I open the link in new tab. URL for the above HTML page in my code is some.html?1234. According to this the value in JS code should be 1234 but it is empty.
So, Flickr Guest Pass URLs are in the following format:
www.flickr.com/x/t/[numericID]/gp/[userID]/[alphanumericID]
Now if I try an API call of the following form:
API_KEY = 'myapikey'
PHOTO_ID = '[numericID]'
SECRET = '[alphanumericID]'
url = 'http://api.flickr.com/services/rest/?method=flickr.photos.getInfo' +
'&api_key=%s&photo_id=%s&secret=%s' % (API_KEY, PHOTO_ID, SECRET)
I do get some photo information back, but for completely the wrong photograph!
It may be relevant that the photo ID in my Guest Pass starts "00": in the info returned by the API, the initial zeros have been chopped off.
Am I supplying the right information to getInfo()?
Figured it out in the end. The Photo ID is in the URL that the Guest Pass resolves to. The secret is in the URL of the jpeg of the photo itself.
So, for example, on a photo:
flickr.com/curiouskiwi/5203020393
The photo ID is the final part of the URL. If you view the photo, you find that the JPG of the URL is
farm6.static.flickr.com/5045/5203020393_f41c8d7fe7_z.jpg
And from that, you know the secret is f41c8d7fe7.
