V2Ray Transport is a set of private protocols invented by v2ray, and has contaminated the names of other protocols, such
|
|
as `trojan-grpc` in clash.
|
|
|
|
### Structure
|
|
|
|
```json
|
|
{
|
|
"type": ""
|
|
}
|
|
```
|
|
|
|
Available transports:
|
|
|
|
* HTTP
|
|
* WebSocket
|
|
* QUIC
|
|
* gRPC
|
|
* HTTPUpgrade
|
|
|
|
!!! warning "Difference from v2ray-core"
|
|
|
|
* No TCP transport, plain HTTP is merged into the HTTP transport.
|
|
* No mKCP transport.
|
|
* No DomainSocket transport.
|
|
|
|
!!! note ""
|
|
|
|
You can ignore the JSON Array [] tag when the content is only one item
|
|
|
|
### HTTP
|
|
|
|
```json
|
|
{
|
|
"type": "http",
|
|
"host": [],
|
|
"path": "",
|
|
"method": "",
|
|
"headers": {},
|
|
"idle_timeout": "15s",
|
|
"ping_timeout": "15s"
|
|
}
|
|
```
|
|
|
|
!!! warning "Difference from v2ray-core"
|
|
|
|
TLS is not enforced. If TLS is not configured, plain HTTP 1.1 is used.
|
|
|
|
#### host
|
|
|
|
List of host domain.
|
|
|
|
The client will choose randomly and the server will verify if not empty.
|
|
|
|
#### path
|
|
|
|
!!! warning
|
|
|
|
V2Ray's documentation says that the path between the server and the client must be consistent,
|
|
but the actual code allows the client to add any suffix to the path.
|
|
sing-box uses the same behavior as V2Ray, but note that the behavior does not exist in `WebSocket` and `HTTPUpgrade` transport.
|
|
|
|
Path of HTTP request.
|
|
|
|
The server will verify.
|
|
|
|
#### method
|
|
|
|
Method of HTTP request.
|
|
|
|
The server will verify if not empty.
|
|
|
|
#### headers
|
|
|
|
Extra headers of HTTP request.
|
|
|
|
The server will write in response if not empty.
|
|
|
|
#### idle_timeout
|
|
|
|
In HTTP2 server:
|
|
|
|
Specifies the time until idle clients should be closed with a GOAWAY frame. PING frames are not considered as activity.
|
|
|
|
In HTTP2 client:
|
|
|
|
Specifies the period of time after which a health check will be performed using a ping frame if no frames have been
|
|
received on the connection.Please note that a ping response is considered a received frame, so if there is no other
|
|
traffic on the connection, the health check will be executed every interval. If the value is zero, no health check will
|
|
be performed.
|
|
|
|
Zero is used by default.
|
|
|
|
#### ping_timeout
|
|
|
|
In HTTP2 client:
|
|
|
|
Specifies the timeout duration after sending a PING frame, within which a response must be received.
|
|
If a response to the PING frame is not received within the specified timeout duration, the connection will be closed.
|
|
The default timeout duration is 15 seconds.
|
|
|
|
### WebSocket
|
|
|
|
```json
|
|
{
|
|
"type": "ws",
|
|
"path": "",
|
|
"headers": {},
|
|
"max_early_data": 0,
|
|
"early_data_header_name": ""
|
|
}
|
|
```
|
|
|
|
#### path
|
|
|
|
Path of HTTP request.
|
|
|
|
The server will verify.
|
|
|
|
#### headers
|
|
|
|
Extra headers of HTTP request.
|
|
|
|
The server will write in response if not empty.
|
|
|
|
#### max_early_data
|
|
|
|
Allowed payload size is in the request. Enabled if not zero.
|
|
|
|
#### early_data_header_name
|
|
|
|
Early data is sent in path instead of header by default.
|
|
|
|
To be compatible with Xray-core, set this to `Sec-WebSocket-Protocol`.
|
|
|
|
It needs to be consistent with the server.
|
|
|
|
### QUIC
|
|
|
|
```json
|
|
{
|
|
"type": "quic"
|
|
}
|
|
```
|
|
|
|
!!! warning "Difference from v2ray-core"
|
|
|
|
No additional encryption support:
|
|
It's basically duplicate encryption. And Xray-core is not compatible with v2ray-core in here.
|
|
|
|
### gRPC
|
|
|
|
!!! note ""
|
|
|
|
standard gRPC has good compatibility but poor performance and is not included by default, see [Installation](/installation/build-from-source/#build-tags).
|
|
|
|
```json
|
|
{
|
|
"type": "grpc",
|
|
"service_name": "TunService",
|
|
"idle_timeout": "15s",
|
|
"ping_timeout": "15s",
|
|
"permit_without_stream": false
|
|
}
|
|
```
|
|
|
|
#### service_name
|
|
|
|
Service name of gRPC.
|
|
|
|
#### idle_timeout
|
|
|
|
In standard gRPC server/client:
|
|
|
|
If the transport doesn't see any activity after a duration of this time,
|
|
it pings the client to check if the connection is still active.
|
|
|
|
In default gRPC server/client:
|
|
|
|
It has the same behavior as the corresponding setting in HTTP transport.
|
|
|
|
#### ping_timeout
|
|
|
|
In standard gRPC server/client:
|
|
|
|
The timeout that after performing a keepalive check, the client will wait for activity.
|
|
If no activity is detected, the connection will be closed.
|
|
|
|
In default gRPC server/client:
|
|
|
|
It has the same behavior as the corresponding setting in HTTP transport.
|
|
|
|
#### permit_without_stream
|
|
|
|
In standard gRPC client:
|
|
|
|
If enabled, the client transport sends keepalive pings even with no active connections.
|
|
If disabled, when there are no active connections, `idle_timeout` and `ping_timeout` will be ignored and no keepalive
|
|
pings will be sent.
|
|
|
|
Disabled by default.
|
|
|
|
### HTTPUpgrade
|
|
|
|
```json
|
|
{
|
|
"type": "httpupgrade",
|
|
"host": "",
|
|
"path": "",
|
|
"headers": {}
|
|
}
|
|
```
|
|
|
|
#### host
|
|
|
|
Host domain.
|
|
|
|
The server will verify if not empty.
|
|
|
|
#### path
|
|
|
|
Path of HTTP request.
|
|
|
|
The server will verify.
|
|
|
|
#### headers
|
|
|
|
Extra headers of HTTP request.
|
|
|
|
The server will write in response if not empty.
