Protobuf枚举消息，值为php中的字符串

Question

我有一个protobuf emun，我在另一条消息中用作字段。我还为此枚举添加了一个自定义选项，为每个选项设置文本版本值

syntax = "proto3";

import "google/protobuf/descriptor.proto";

package Message;

extend google.protobuf.EnumValueOptions {
    optional string name = 10001;
}
enum ScreenshotStatus {
    UNKNOWN = 0 [(name) = "unknown"];
    IN_QUEUE = 1 [(name) = "in_queue"];
    PROGRESSING = 2 [(name) = "[progressing"];
    FINISHED = 3 [(name) = "finished"];
    RUNNING = 4 [(name) = "running"];
}

然而，当我为protobufs生成php类时，我得到普通的旧类，没有任何方法来获取枚举名称。

class ScreenshotStatus
{
    /**
     * Generated from protobuf enum <code>UNKNOWN = 0 [(.Message.name) = "unknown"];</code>
     */
    const UNKNOWN = 0;
}

有没有办法获取ScreenshotStatus :: UNKNOWN的名称值，反之亦然 - 按名称获取正确的枚举＆＃34; unknown＆＃34;。
