I'd like to send base64 image as an attachment to a trello card through the API
POST /1/cards/[card id or shortlink]/attachments
There's a file field but it does not specify how should look the data there.
Refs: https://developers.trello.com/advanced-reference/card#post-1-cards-card-id-or-shortlink-attachments
Any idea?
Short answer: Trello's API only works to attach binary data via multipart/form-data. Examples below.
Long answer:
The Trello API to add attachments and images is frustratingly under-documented. They do have a coffeescript Client.js for those of us using Javascript to simplify all the basic operations: https://trello.com/1/client.coffee
Using the vanilla Client.js file I have been able to attach links and text files. While the CURL example shows pulling a binary file in from a hard drive, that doesn't work for those of us completely on a server or client where we don't have permissions to create a file.
From a LOT of trial and error, I've determined all binary data (images, documents, etc.) must be attached using multipart/form-data. Here is a jQuery snippet that will take a URL to an item, get it into memory, and then send it to Trello.
var opts = {'key': 'YOUR TRELLO KEY', 'token': 'YOUR TRELLO TOKEN'};
var xhr = new XMLHttpRequest();
xhr.open('get', params); // params is a URL to a file to grab
xhr.responseType = 'blob'; // Use blob to get the file's mimetype
xhr.onload = function() {
var fileReader = new FileReader();
fileReader.onload = function() {
var filename = (params.split('/').pop().split('#')[0].split('?')[0]) || params || '?'; // Removes # or ? after filename
var file = new File([this.result], filename);
var form = new FormData(); // this is the formdata Trello needs
form.append("file", file);
$.each(['key', 'token'], function(iter, item) {
form.append(item, opts.data[item] || 'ERROR! Missing "' + item + '"');
});
$.extend(opts, {
method: "POST",
data: form,
cache: false,
contentType: false,
processData: false
});
return $.ajax(opts);
};
fileReader.readAsArrayBuffer(xhr.response); // Use filereader on blob to get content
};
xhr.send();
I have submitted a new coffeescript for Trello developer support to consider uploading to replace Client.js. It adds a "Trello.upload(url)" that does this work.
I've also attached here for convenience in JS form.

I have an express app that I am using Sharp to resize images after a user has uploaded them. When I start the app using 'npm start' I am able to upload the images with no issues, but if I use PM2 to manage the process the images don't get saved on the server. I can save them without using Sharp to resize them, it is only when I have the code for sharp that they don't get saved. Below is the code from my controller. Multer is processing the form and sharp is resizing the image.
doNewRecipe: function(req, res) {
for (var key in req.body) {
req.body[key] = req.body[key] || undefined;
}
var body = _.pick(req.body, 'title', 'description', 'ingredients', 'instructions', 'yield', 'prep_time', 'cook_time', 'categoryId');
body.userId = req.session.user.id;
if (req.file) {
var tempPath = req.file.path,
ext = path.extname(req.file.originalname).toLowerCase(),
//targetPath = path.resolve(finalUploadPath + req.file.filename + ext);
targetPath = path.resolve(finalUploadPath);
fs.renameSync(tempPath, tempPath + ext);
var newFileName = req.file.filename + ext;
var imageFile = tempPath + ext;
body.image = newFileName;
sharp(imageFile)
.resize(450, 450)
.max()
.toFile('./public/finalUpload/' + newFileName, function(err, info) {
body.image = newFileName;
fs.unlinkSync(path.resolve(tempPath + ext));
db.recipe.create(body).then(function(recipe) {
res.redirect('/recipe/view/' + recipe.id);
}, function(e) {
console.log(e.message);
res.render('error', {message: e.toString()});
});
});
//fs.renameSync(tempPath, targetPath);
} else {
db.recipe.create(body).then(function(recipe) {
res.redirect('/recipe/view/' + recipe.id);
}, function(e) {
console.log(e.message);
res.render('error', {message: e.toString()});
});
}
},
If you use path to determine where to save the file it will transport easily from one system to another. I actually created a few variables to determine where to save the file. Below is my code.
if (process.env.NODE_ENV === 'production') {
var finalUploadPath = 'hidden';
var googleTracking = true;
} else if (process.env.NODE_ENV === 'staging') {
var finalUploadPath = 'hidden';
var googleTracking = false;
} else {
var finalUploadPath = 'hidden';
var googleTracking = false;
}
sharp(imageFile)
.resize(450, 450)
.max()
.toFile(finalUploadPath + req.file.filename + '.jpg', function(err, info) {
body.image = req.file.filename + '.jpg';
fs.unlinkSync(path.resolve(tempPath + ext));
compressAndResize(path.resolve(__dirname, '../public/finalUpload/' + body.image));
db.recipe.create(body).then(function(recipe) {
req.flash('success', 'Recipe created');
res.redirect('/recipe/view/' + recipe.id + '/' + recipe.slug);
}, function(e) {
console.log(e.message);
req.flash('error', 'Error creating new recipe');
res.render('error', {message: e.toString(), csrfToken: req.csrfToken(), google: googleTracking});
});
});
I have made a code that parses all URL-s from a page. Next, I would like to get a href from every parsed URL <div class="holder"></div> and output it to a file and sepparate with a comma.
So far I have made this code. It is able to find all the URL-s need to be parsed and collects them to a comma sepparated file called output2.txt.
var resourceWait = 300,
maxRenderWait = 10000,
url = 'URL TO PARSE HREF-s FROM';
var page = require('webpage').create(),
count = 0,
forcedRenderTimeout,
renderTimeout;
page.viewportSize = { width: 1280, height : 1024 };
function doRender() {
var fs = require('fs');
var path = 'output2.txt';
page.includeJs("http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js", function() {
fs.write(path,page.evaluate(function() {
return $('.urlDIV').find('a')
.map(function() {
return this.href;})
.get()
.join(',');
}), 'w');
phantom.exit()
});
}
page.onResourceRequested = function (req) {
count += 1;
clearTimeout(renderTimeout);
};
page.onResourceReceived = function (res) {
if (!res.stage || res.stage === 'end') {
count -= 1;
if (count === 0) {
renderTimeout = setTimeout(doRender, resourceWait);
}
}
};
page.open(url, function (status) {
if (status !== "success") {
phantom.exit();
} else {
forcedRenderTimeout = setTimeout(function () {
console.log(count);
doRender();
}, maxRenderWait);
}
});

In WS API there is no object "feature". Please try either portfolioitem/feature or portfolioitem and then filter out by _type, e.g.
if(results.pi[i]._type == "PortfolioItem/Feature"){ //...
as shown here.
Since you are using a legacy AppSDK1 I assume you are setting a version to 1.43 as mentioned in this post.
I am a freshman on skydrive. then I want to use file picker in html, and copy the demo code from Interactive Live SDK. but the running result, the open window is not direct to file picker page, just direct to my setting redirect_uri page. so what's wrong with my demo page? thanks

I found the reason. the redirect_uri must same with the filling in the app registeration.
