I am running into a bit of a snag setting up pagination in Google Apps Script. I am trying to use it for Shopify API. Reference links attached.
I attached the code below of what I have so far -
trying to figure out how to use the "While" statement to make it check if there is a Next Page URL
trying to figure out a way to parse the Link in the header. Example below. On pages 2+ there will be a next and previous link. We only need the next

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'm trying to get the exchanges in ripple and I found this data API and its working. But I want to use the ripple websocket tool for some reasons. Is there any websocket equivalent for this data API?
I think there is equivalent if you use "tx_history" command in the socket but Sorry to tell you that the json result are not equal to your specific data result.
ripple data apiv2 is being played by ajax. see the result json formatter in ripple for exchange:
} else if (resp.rows.length) {

base_currency: resp.rows[0].base_currency,
base_issuer: resp.rows[0].base_issuer,
base_amount: resp.rows[0].base_amount,
counter_amount: resp.rows[0].counter_amount,
counter_currency: resp.rows[0].counter_currency,
counter_issuer: resp.rows[0].counter_issuer,
rate: resp.rows[0].rate,
executed_time: resp.rows[0].executed_time,
ledger_index: resp.rows[0].ledger_index,
buyer: resp.rows[0].buyer,
seller: resp.rows[0].seller,
taker: resp.rows[0].taker,

autobridged_currency: resp.rows[0].autobridged_currency,
autobridged_issuer: resp.rows[0].autobridged_issuer,
offer_sequence: resp.rows[0].offer_sequence,
tx_type: resp.rows[0].tx_type,

Maybe you should make a custom websocket that make your RPC call upgrade to 1.1 http protocol (ws).
In nodejs you can simply
// for http
var http = require('http');
// for websocket
var ws = require("nodejs-websocket")
var options = {
host: 'URL-RPC-HERE',
port: '80',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': post_data.length
}
};
var req = http.request(options, function(res) {
// after getting the response wich is the <res>
// we can upgrade it to ws
upToWebsocket(res);
});
//Upgrade to websocket
var upToWebsocket = function(json) {
var server = ws.createServer(function (conn) {
conn.on("json", function (str) {
conn.sendText(str.toUpperCase()+"!!!")
})
conn.on("close", function (code, reason) {
console.log("Connection closed")
})
}).listen(8001)
}
And also if you have Rippled running on a server this does not help because there's no RPC or WS that supports exchange API.

I'm invoking like this:
try
{
var loginInput = new JObject();
loginInput.Add("userName", "breno");
loginInput.Add("password", "test");
var loginResult = await LoginAuthenticationService.InvokeApiAsync("login", loginInput);
LoginAuthenticationService.CurrentUser = new MobileServiceUser((string)loginResult["user"]);
LoginAuthenticationService.CurrentUser.MobileServiceAuthenticationToken = (string)loginResult["token"];
}
catch (MobileServiceInvalidOperationException e)
{
var exception = e;
}
If you're getting this error "Failed to load script file 'login.js': SyntaxError: Unexpected token }" as seen in the comments, there is a syntax issue with your script. You'll need to go through your scripts and figure out where the issue is at.
i am new to programming.. i have this code which gives distance between two points but need to further multiply it by an integer say 10.. the project i am working on is abt calculating distance between two points and multiplying it with fare/Km like Rs.10/km (Indian Rupees) for the same. So if the distance is 30 km the fare would be 30*10 = Rs.300
Thanks in advance
following is the code

I use an Ajax call to PHP, and haven't yet used getDistanceMatrix(), but this should be an easy fix.
First, if you know you will always only have one origin and one destination, you don't need the "for" loop in your callback function. Second, you're taking the distance text rather than the distance value.
function callback(response, status) {
if (status != google.maps.DistanceMatrixStatus.OK) {
[...]
} else {
deleteOverlays();
var outputDiv = document.getElementById('outputDiv'),
origin = response.originAddresses[0],
destination = response.destinationAddresses[0],
result = response.rows[0].elements[0],
distance = result.distance.value,
text = result.distance.text,
price = 10 * distance;
outputDiv.innerHTML = '<p>' + text + ': Rs.' + price + '</p>';
addMarker(origin, false);
addMarker(destination, false);
}
}
I haven't tested this, so it probably needs to be tweaked. ( See https://developers.google.com/maps/documentation/distancematrix/#DistanceMatrixResponses )
