Node red not working with https - https

Following various posts about running Node-red as https, I've done the following:
Made the following changes in settings.js:
var fs = require("fs");
...
https: {
key: fs.readFileSync('privkey.pem'),
cert: fs.readFileSync('cert.pem')
},
...
requireHttps: true
Created privkey.pem and cert.pem.
Verified files exist in ~/node-red (Raspberry Pi).
Node.js version v8.9.4
Node-RED version v0.17.5
When I do https://raspberrypi:1880 I get "The site cannot be reached" but http://raspberrypi:1880 still works. I even tried rebooting the Pi.

This was a simple operator error. I had two dirs. One .node-red and one node-red (FYI: Only install node-red using one way and not several [duh]).
When node-red was loading I miss read the working directory and modified the wrong settings.js

Error: No such file (sftp liximomo extension)

I have this problem when I upload a file on the server using the extension liximomo/vscode-sftp for visual studio code.
[error] Error: No such file
at SFTPStream._transform
at SFTPStream.Transform._read
at SFTPStream._read
How I can fix this problem? I tried to upload files to different servers, so I guess it's not a server-related problem but an extension.
There is a better fix on GitHub that works for upload and download via SFTP extension:
Do a search inside ~/.vscode/extensions/liximomo.sftp-1.12.9/node_modules/ssh2-streams/lib/sftp.js for options.emitClose = false;
Add options.autoDestroy = false; after both instances.

This is apparently a brand new problem that has been introduced into the newer versions of VS Code. I have FOUND A SOLUTION that seems to work well, by modifying a single line in the extension code. This is only valid for version 1.12.9 of the liximomo.sftp extension.
Here are the steps:
Shutdown / Quit VS Code.
Locate the following file:Mac OS X:
~/.vscode/extensions/liximomo.sftp-1.12.9/node_modules/ssh2-streams/lib/sftp.jsWindows:C:\Users\account_name\.vscode\extensions\liximomo.sftp-1.12.9\node_modules\ssh2-streams\lib\sftp.js
Make a backup copy of the file.
Modify line 388, which should be:if ( code === STATUS_CODE . OK ) { changing it to:if (code === STATUS_CODE.OK || code === STATUS_CODE.NO_SUCH_FILE) {
Save the file.
Relaunch VS Code; test by uploading or downloading from your sftp server. The error should not be present.
The alternative solution involves downgrading your version of VS Code. This is not desirable as you are not getting the latest fixes, security patches, etc..
See the following links regarding this issue:
https://github.com/liximomo/vscode-sftp/issues/266
https://github.com/liximomo/vscode-sftp/issues/569 (repeat)
https://gitmemory.com/issue/liximomo/vscode-sftp/915/827578565 (note, this site has a bad SSL certificate).
If you want to downgrade your VS Code; use this link to find the older versions:
https://code.visualstudio.com/updates/v1_55

From their blog entry (translated by Google to English):
"At first, there was no solution, but Now, 12 hours later, the Holy
One appeared, who told me how to solve it.files that sftp cannot find
in the first place. There is a calling phrase, VScode is upgraded and
an error is called. It came out. Actually, I did not solve the
problem. Even if the file is not found, the same result as the
success process is exported. It is just a modification. It is
expected that a modified version will be released in the future."
Not an answer to the problem, but solution in another (simple) way:
install Run On Save VSCode extension
write a deploy.sh script along the lines
rsync -avz -e 'ssh -i /home/user/.ssh/id_rsa' --exclude '.history' --exclude '.vscode' --exclude '.git' --exclude '.gitignore' --exclude 'deploy.sh' ./ user#domain.net:/home/user/public_html/
add the following configuration to VSCode settings.json to trigger the deploy.sh script on file save:
"emeraldwalk.runonsave": {
"commands": [
{
"match": ".*",
"isAsync": false,
"cmd": "${workspaceFolder}/deploy.sh"
},
]
}
Just switch to the second one:
There is another solution only upgrading the ssh2 package from the extension.
You just need to go to the extension path:
Windows:
C:\Users\your-user\.vscode\extensions\liximomo.sftp-1.12.9
When you are there, change the version of ssh2 package on the package.json file to ^1.1.0. Finally, just run npm install.
You should restart VSCode.
Alternatively, you could use a fork of the repository that is active and fixing these issues: https://github.com/Natizyskunk/vscode-sftp

Vapor `Public` directory inside docker image is not exposed

I'm running Vapor 4.3 and Leaf with Xcode on my Mac without any issues.
public directory middleware is enabled:
let fileMW = FileMiddleware(publicDirectory: directory)
app.middleware.use(fileMW)
as soon as I build the image using the default dockerfile and run it on the docker, the css and all image files are not loaded anymore.
Note: the dockerfile is the exact same one that came with the vapor new command. (Updated to the date of the writing this post)
Safari shows this error:
[Error] Did not parse stylesheet at 'http://127.0.0.1/styles/index.css' because non CSS MIME types are not allowed in strict mode.
Chrome shows this warning:
Resource interpreted as Stylesheet but transferred with MIME type text/plain: "http://127.0.0.1/styles/index.css".
What am I missing?
Looks like it is a case sensitivity issue! Mac has no problem finding files with this issue but Linux not!
⚠️ Even if you already set: app.routes.caseInsensitive = true, it will not affect your resources requests.
So make sure you have set all paths exactly as they appear in pwd command.

Selenium WebDriverException: Reached error page

I am following a Django TDD tutorial at:
http://www.marinamele.com/taskbuster-django-tutorial/taskbuster-working-environment-and-start-django-project
I get the following error when running 'all_users.py' before and after I start the development server 'python manage.py runserver':

Basically the connection to localhost cannot be established.
The settings and configurations are identical to the tutorial in the previous link.
I have been struggling with the issue for two days, and would thank you most kindly if you could provide any help.
I got the same error and what solved for me was changing from localhost to 127.0.0.1:
old: self.browser.get('http://localhost:8000')
better: self.browser.get('http://127.0.0.1:8000')
I encountered the same problem, the final solution is: re-install again geckodriver
Unzip the geckodriver.zip
Move the file to /usr/bin directory sudo mv geckodriver /usr/bin
Goto /usr/bin directory cd /usr/bin,then you would need to run something like sudo chmod a+x geckodriver to mark it executable.
this might not be your situation, but I got the same error message when running a test (same book, hehe) without having anything actually listening on the targeted port (8000, in my case). Make sure there's something listening for a request by manually opening your browser and going to localhost:8000. In my case - silly me - I didn't have the server up at all =)
I also followed the same tutorial and came across the same error. I noticed that I am not running the django server. The following is what helped.
python manage.py runserver
python functional_test.py
Being that this is a snapshot (around Django 1.8's time) of "Obey The Testing Goat" - perhaps the instructions there are no longer relevant. I suggest going straight to the goat's mouth and starting over!
The issue could be related to virtualenvwrapper (which is no longer necessary) or it could be related to the port/address that you were trying to access. Depending on your version of Selenium and Firefox there may be issues related to that as well.
It depends on the situation.
Based on mine, after I changed the target URL, I can get the browser to load the URL normally, which means the original URL is not available.
Another way to check:
import requests
html = request.get(url)
Print the HTML, if you get the 503, which means the website is reachable.
Since this is probably a common search result for those working through Obey the Testing Goat, I wanted to share the solution that worked for me. I had written self.browser.get('http://localhost:8000') and needed to use http instead of https to resolve the error.
I got this problem in this situation: the application put the computer name to the proxy host,so the proxy like this:
theComputerName:proxyPort
but the theComputerName:proxyPort can not be visit,so I put this into the host:
127.0.0.1 theComputerName
then restart the application,the problem resolved perfect
I learning TDD tutorial too. My problem was that inputed uncorrect url
http://http://mysite insted of http://mysite

D3, loading a csv file, filepath issue ? [duplicate]

I'm just learning d3, and I'm attempting to import data from a CSV file, but I keep getting the error "XMLHttpRequest cannot load file:///Users/Laura/Desktop/SampleECG.csv. Cross origin requests are only supported for HTTP. ". I've searched for how to fix this error and have ran it on a local web server, but I haven't found a solution that works for d3.v2.js. Here's a sample of the code:
var Time = []
ECG1 = []
d3.csv("/Desktop/d3Project/Sample.csv", function(data)
{
Time = data.map(function(d) {return [+d["Time"]];});
ECG1 = data.map(function(d) {return [+d["ECG1"]];});
console.log(Time)
console.log(ECG1)
});
Any help will be much appreciated.
This confused me too (I am also a d3 beginner).
So, for some reason, web browsers are not happy about you loading local data, probably for security reasons or something. Anyways, to get around this, you have to run a local web server. This is easy.
In your terminal, after cd-ing to your website's document root (thanks #daixtr), type:
python -m SimpleHTTPServer 8888 &
Okay, now as long as that terminal window is open and running, your local 8888 web server will be running.
So in my case, originally the web page I was working on was called
file://localhost/Users/hills/Desktop/website/visualizing-us-bls-data-inflation-and-prices.html
When I opened it in chrome. To open up my page on my local web server, I just typed (into the chrome search bar):
http://localhost:8888/Desktop/website/visualizing-us-bls-data-inflation-and-prices.html
Now, reading in CSVs should work. Weird, I know.
To those using built-in python webserver and who are still experiencing issues, do REMEMBER and make sure that you run the "python -m SimpleHTTPServer 8888" invocation at the correct path of which you consider to be your DocumentRoot. That is, you cannot just run 'python -m SimpleHTTPServer 8888' anywhere. You have to actually 'cd /to/correct/path/' containing your index.html or data.tsv and then from there run 'python -m SimpleHTTPServer 8888'.
Also, just learning D3 for school work. I was trying to run this simple D3 example:
https://gist.github.com/d3noob/b3ff6ae1c120eea654b5
I had the same problem as OP re: loading data using Chrome browser. I bet the great solution Hillary Sanders posted above was re: Python 2.X.
My answer is re: Python 3.X [OS: Ubuntu 16x]:
Open a terminal window within the root directory of your project, then run:
python3 -m http.server
It will serve HTTP on port 8000 by default unless it is already taken, in that case to open another port, e.g. 7800, run:
python3 -m http.server 7800
Then, on your Chrome browser address bar type:
localhost:8000
The above worked for me because I only had an index.html page in my root folder. In case, you have a HTML page with a different name, type the whole path to that local HTML page and it should work also. And, you should be able to see the graph created from the data set in my link (that must be in a folder like data/data.csv). I hope this helps. :-)
Use Firefox, idk what Chrome tries to accomplish

Node.js, Session with infinite loop

I'm using expressjs and connect-mongo#0.1.7 as the MongoStore for session.
What happen is, the session code was working. but after I upgrade node and npm to the latest version, and Mongo to 2.0.2, then if I put express.session ( store:new MongoStore) then it will run a infinite loop. Any idea what's happening?
here is my code:
express.createServer(
express.cookieParser(),
express.bodyParser(),
express.session({ secret: cfg.session_secret,
cookie: { domain: 'mydomain.com' },
store:new MongoStore({
db: cfg.db_session_name,
host: cfg.db_ip,
port: cfg.db_port
})
})
)
Here is the error:
TypeError: Not a string or buffer

Just got the temp solution for that. from another noder "jacobstr"
see this: https://github.com/kcbanner/connect-mongo/issues/29#issuecomment-4233108
So, I go to node_modules/connect-mongo folder. Edit the package.json like that: https://github.com/jacobstr/connect-mongo/blob/master/package.json (only one change: <2 ).
Then in that folder, run sudo npm install -d
then everything works. :)
I ran into the same issue. I believe this is being caused by express and connect-mongo using different versions of connect and those different versions have different method signatures for the cookieParser. The version connect-mongo is using expects to be passed a "secret" key for signing the session data, but the version express uses does not supply it.
There is an update to express on GitHub to support connect 2.0, but it is not available via npm yet.
