Strongloop/Loopback gRPC 连接器
Strongloop/Loopback connector for gRPC
环境:
- strongloop v6.0.3
- 节点 v6.11.2
- loopback-cli@3.1.0
- 环回连接器-grpc@1.1.0
问题:
创建 gRPC 数据源时,它不读取 proto 文件并抛出错误
错误:
if (err) throw err;^
TypeError: Cannot initialize connector "loopback-connector-grpc": Cannot read property 'ns' of null

复制步骤:
我刚刚阅读了 loopback-connector-grpc 官方存储库中的文档。
我用代码试过了,它没有创建数据源
var ds = loopback.createDataSource('grpc', {
connector: 'loopback-connector-grpc',
spec: 'note.proto',
});
我也试过这个:
"gRPCDataSource": {
"name": "gRPCDataSource",
"connector": "grpc",
"spec": "note.proto",
"security": {
"type" : "basic",
"username": "the user name",
"password": "thepassword"
}
但还是一样的结果。
我也使用了这个命令lb datasource
按照步骤,下载了连接器,同样的错误。
找到了,我只是移动了proto文件目录。
它必须在项目根目录
环境:
- strongloop v6.0.3
- 节点 v6.11.2
- loopback-cli@3.1.0
- 环回连接器-grpc@1.1.0
