I am trying to use the Object Storage Service at IBM Bluemix Cloud, but I can't send images from my nodejs server. How can I do this? Follow my server code:
unirest
.post(MY_CONTAINER + new_fname)
.headers({'Content-Type': 'multipart/form-data', 'X-Auth-Token': token})
.field({ 'max_file_count': 1 })
.field({ 'max_file_size': 1 })
.attach({ 'file': file.originalname, 'relative file': streamFile })
.end(function (resp) {
//response
console.log(resp.status);
console.log(resp.body);
});
The main problem is to find the right way to send an image (png or jpg) to the bluemix storage using the API (I've aready uploaded it to our server).
I used the pkgcloud-bluemix-objectstorage to fix the OpenStack authentication bug that previously used the v2 and has been changed to use the v3.
here's the link Bluemix - object storage - node.js - pkgcloud - openstack returns 401
the @libik writes an example.
var pkgcloud = require('pkgcloud-bluemix-objectstorage');
var fs = require('fs');
// Create a config object
var config = {};
// Specify Openstack as the provider
config.provider = "openstack";
// Authentication url
config.authUrl = 'https://identity.open.softlayer.com/';
config.region= 'dallas';
// Use the service catalog
config.useServiceCatalog = true;
// true for applications running inside Bluemix, otherwise false
config.useInternal = false;
// projectId as provided in your Service Credentials
config.tenantId = '234567890-0987654';
// userId as provided in your Service Credentials
config.userId = '098765434567890';
// username as provided in your Service Credentials
config.username = 'admin_34567890-09876543';
// password as provided in your Service Credentials
config.password = 'sdfghjklkjhgfds';
**//This is part which is NOT in original pkgcloud. This is how it works with newest version of bluemix and pkgcloud at 22.12.2015.
//In reality, anything you put in this config.auth will be send in body to server, so if you need change anything to make it work, you can. PS : Yes, these are the same credentials as you put to config before.
//I do not fill this automatically to make it transparent.
config.auth = {
forceUri : "https://identity.open.softlayer.com/v3/auth/tokens", //force uri to v3, usually you take the baseurl for authentication and add this to it /v3/auth/tokens (at least in bluemix)
interfaceName : "public", //use public for apps outside bluemix and internal for apps inside bluemix. There is also admin interface, I personally do not know, what it is for.
"identity": {
"methods": [
"password"
],

//console.log("config: " + JSON.stringify(config));
// Create a pkgcloud storage client
var storageClient = pkgcloud.storage.createClient(config);
// Authenticate to OpenStack
storageClient.auth(function (error) {
if (error) {
console.error("storageClient.auth() : error creating storage client: ", error);
} else {
//OK
var new_fname = dir + "__" + file.originalname;
var readStream = fs.createReadStream('uploads/' + file.filename);
var writeStream = storageClient.upload({
container: 'chat-files',
remote: new_fname
});
writeStream.on('error', function(err) {
// handle your error case
console.log("concluido o upload com erro!");
console.log(err);
});
writeStream.on('success', function(file) {
// success, file will be a File model
console.log("concluido o upload com sucesso!");
});
readStream.pipe(writeStream);
}
});
