Question

I have the same situation with HERE

And to solve this problem I have to launch html file using Chrome at \"--allow-file-access-from-files\" mode. I tried next steps

Answer 1

That flag is dangerous!! Leaves your file system open for access. Documents originating from anywhere, local or web, should not, by default, have any access to local file:/// resources.

Much better solution is to run a little http server locally.

--- For Windows ---

The easiest is to install http-server globally using node's package manager:

npm install -g http-server

Then simply run http-server in any of your project directories:

Eg. d:\my_project> http-server

Starting up http-server, serving ./
Available on:
 http:169.254.116.232:8080
 http:192.168.88.1:8080
 http:192.168.0.7:8080
 http:127.0.0.1:8080
Hit CTRL-C to stop the server

Or as prusswan suggested, you can also install Python under windows, and follow the instructions below.

--- For Linux ---

Since Python is usually available in most linux distributions, just run python -m SimpleHTTPServer in your project directory, and you can load your page on http://localhost:8000

In Python 3 the SimpleHTTPServer module has been merged into http.server, so the new command is python3 -m http.server.

Easy, and no security risk of accidentally leaving your browser open vulnerable.

REM Kill all existing instance of chrome 
taskkill /F /IM chrome.exe /T
REM directory path where chrome.exe is located
set chromeLocation="C:\Program Files (x86)\Google\Chrome\Application"
cd %chromeLocation%
cd c:
start chrome.exe --allow-file-access-from-files

save above lines as .bat file

Answer 3

Depending on the file which will be put into filesystem, as long as that file is not a malware, then that would be safe.

But don't worry to write/read file(s) to File System directory, cause you can tighten that directory security (include it's inheritance) by give a proper access right and security restriction. eg: read/write/modify.

By default, File System, Local Storage, and Storage directory are located on "\Users[Current User]\AppData\Local\Google\Chrome\User Data\Default" directory.

However you can customize it by using "--user-data-dir" flag.

And this is a sample:

"C:\Program Files (x86)\Google\Application\chrome.exe" --user-data-dir="C:\Chrome_Data\OO7" --allow-file-access-from-files

Hope this helps anyone.

Answer 4

Search for the path of your Chrome executable and then, on your cmd, try :

> "C:\PathTo\Chrome.exe" --allow-file-access-from-files

Source

EDIT : As I see on your question, don't forget that Windows is a little bit similar to Unix, so when you type "chrome ...", cmd will search for Chrome in the PATH, but in general the Chrome folder isn't on the PATH. Also, you don't specify an extension for your executable... So if you move to Chrome's folder, this command will probably work too :

> .\chrome.exe --allow-file-access-from-files

Answer 5

Quit (force quit) all instances of chrome. Otherwise the below command will not work.

open -a "Google Chrome" --args --allow-file-access-from-files

Executing this command in terminal will open Chrome regardless of where it is installed.
