Question

Hi,

I would like to set openvpn client properties remotely by using JSON RPC. I have already created the vpn configuration but I don't know how to upload files that are necessary (cert, ca, key and tls_auth). Is it possible to do it through JSON RPC or I need to upload them through SSH ?

Thank you

Answer 1

Hello,

try something with this one.

Source: https://github.com/openwrt/luci/wiki/JsonRpcHowTo

The Filesystem library /rpc/fs offers functionality to interact with the filesystem on the host machine.

Exported Functions:

• Complete luci.fs library

Note: All functions are exported as they are except for readfile which encodes its return value in Base64 and writefile which only accepts Base64 encoded data as second argument. Note that both functions will only be available when the luasocket packet is installed on the host system.

Answer 2

It is possible to download a file without additional packet with this message on http://192.168.1.1/ubus

{ "jsonrpc" : "2.0", "id" : 1, "method" : "call", "params" : ["file", "read", {"path" : "PATH OF THE FILE"}]}

And to upload one with this message on http://192.168.1.1/ubus

{ "jsonrpc" : "2.0", "id" : 1, "method" : "call", "params" : ["file", "write", {"path" : "PATH OF THE FILE", "data" : "File data as String"}]}

However, data must be string as it is not encoded.

Comments

Params also take "base64":true or "base64":false parameter but even in base64 there still are errors on readind / writing binary files
