NOTE.md

Try this script if you want to generate V2RayN style links:

• https://gist.github.com/zjx20/7f86b74750f4441c747b9df501cfe22a

Does this script convert a V2ray config.json to a vmess URL?

Does this script convert a V2ray config.json to a vmess URL?

@agn-7 Yes, if you base64 decode the output file.

@zjx20 But I don't why neither the generated QRcode nor rss.txt content work as an imported config file.

Here's my config file:

{
	"log": {
		"loglevel": "warning"
	},
	"inbounds": [{
			"port": 1080,
			"protocol": "socks",
			"settings": {
				"udp": true
			}
		},
		{
			"port": 8880,
			"protocol": "http",
			"allowTransparent": false,
			"userLevel": 0
		}
	],
	"outbounds": [{
			"protocol": "vmess",
			"settings": {
				"vnext": [{
					"address": "xxxx",
					"port": 18345,
					"users": [{
						"id": "xxxx",
						"alterId": 0,
						"security": "aes-128-gcm"

					}]
				}]
			},
			"streamSettings": {
				"network": "ws",
				"wsSettings": {
					"path": "/vmess"

				}
			}
		},
		{
			"protocol": "freedom",
			"tag": "direct"
		}
	],
	"routing": {
		"domainStrategy": "IPOnDemand",
		"rules": [

			{

				"domain": ["ext:iran.dat:ir"],
				"outboundTag": "direct",
				"type": "field"
			},
			{

				"domain": ["regexp:.*\\.ir$"],
				"outboundTag": "direct",
				"type": "field"
			},
			{
				"domain": ["regexp:.*\\.cab$"],
				"outboundTag": "direct",
				"type": "field"
			},
			{

				"domain": ["ext:iran.dat:other"],
				"outboundTag": "direct",
				"type": "field"
			},
			{
				"domain": ["ext:iran.dat:other"],
				"outboundTag": "direct",
				"type": "field"
			}
		]
	}
}

But this config file does work without any problem as a configuration on v2ray-core.

@agn-7
shadowrocket can recognize the QR code and the content. Since there isn't a standard for the vmess URL schema and the subscription, don't expect it works for every app.

After converting your config file, we get:

$ cat rss.txt | base64 -d
vmess://YWVzLTEyOC1nY206eHh4eEB4eHh4OjE4MzQ1?remarks=null&path=/vmess&obfs=websocket&obfsParam=null&tls=0&mux=0&alterId=0

Since you're not enabling TLS, the script produced a null value for the obfsParam param, which might cause problems.

@zjx20
Thank you for your instant response. However, I couldn't import this vmess URL into Nekoray or V2rayNG apps.

@agn-7
I don't use both of them, but I found a URL example from here. It's a totally different format than the one used in this script, so it won't work. I do not intend to add support for that, you can try it yourself.

@zjx20
ooh, thanks. I didn't know there are different types of vmess URL !

@zjx20
I would also love to know how to convert a JSON file to a URL, but the English of "base64 decode output file" is just way too much for me, I'm not an IT guy.

@mulezic Sorry, I can't help you if you are not familiar with this IT stuff (e.g. shell scripts, base64 encoding, etc.). Maybe you can say more about what you're trying to do, and maybe it can be solved in a different way.

I created my own V2ray proxy servers using some scripts I found on YouTube. I have been doing this for some using scripts that generate my V2ray server account in a QR Code format where I just have to scan the code into my V2ray client or the Vmess/Vless URL format where I just copy and import into a V2ray client. Now, the challenge I have is that the recent script I found only gives the option to save your created server account in JSON format. With JSON format, I'm limited to VPN clients I can import my servers in since most of them do not support JSON format. So, I thought there was a way I could convert a JSON file to a common Vmess, Vless URL format. I don't know if I'm making sense.

@mulezic OK, I understand. You can tell me what server software or script you are using, what client you are planning to use, and also a sample json config (without sensitive information). I can help you determine the feasibility of the situation.
