it wouldn't send more data after the init request is done for some reason

Seems they have impl gRPC transport in their another project: https://github.com/Qv2ray/v2ray-rust/blob/dev/src/proxy/grpc/mod.rs

I am backport this to this project to have a test

EDIT: This impl is not work yet ...... 😅

Yeah I think there’s something wrong in how they handle the array boundry.

Another thing can be done is maybe to try the grpc with Trojan (I’ve put it in too in this PR) and see if it’s actually the problem of our grpc impl or only grpc with vmesd is the issue

I test currect pr in trojan with gRPC( xray is the backend), using the config:

{
  "log": {
    "loglevel": "debug" // Level of log
  },
  "inbounds": [
    {
      "port": 12312,
      "protocol": "trojan",
      "settings": {
        "clients": [
          {
            "password": "password",
            "email": "love@xray.com",
            "level": 0
          }
        ],
        "fallbacks": [
          {
            "dest": 80
          }
        ]
      },
      "streamSettings": {
        "network": "grpc",
        "grpcSettings": {
          "serviceName": "abc"
        },
        "security": "none"
      }
    }
  ],
  "outbounds": [
    {
      "protocol": "freedom",
      "settings": {}
    }
  ]
}

It seems small page, such as www.baidu.com can get a response immediately. and huge page like www.aliyun.com, www.google.com, or a pure huge http page http://www.galgamez.me/bbs/, could get a buffer out of range error:

split_to out of bounds: 4096 <= 4054

Ok nice we are making progresses. 👍

I'll take a look later. Thanks!
