冲突版本是什么？

[liutaot]

冲突版本是什么？

php 8.0
protobuf 3.18
skywalking master

[heyanlong]

protobuf是加载什么proto文件了吗？

[liutaot]

protobuf是加载什么proto文件了吗？

proto文件内容如下：

syntax = "proto3";

package example;

service example {
    rpc hello (HelloRequest) returns (HelloReply) {
    }
}

message HelloRequest {
    string name = 1;
}

message HelloReply {
    int32 code = 1;
    string message = 2;
}

[heyanlong]

是 HelloRequest 冲突了

[heyanlong]

如果不是skywalking最新版本，目前无解。skywalking 最新版本修复了这个问题。

[heyanlong]

PHP agent还没做升级最新版本

[liutaot]

是 HelloRequest 冲突了

syntax = "proto3";

package example;

service example {
    rpc hello (AbcRequest) returns (AbcReply) {
    }
}

message AbcRequest {
    string name = 1;
}

message AbcReply {
    int32 code = 1;
    string message = 2;
}

这样也不行

[liutaot]

skywalking 版本是 8.6

sky php agent 版本是master
