4 years ago 可能的问题有：
- 创建Fabric网络的时候，组织的名称是什么？_Org1，Org2_还是org1，org2，注意大小写。
- 创建connection-x.yml文件时，组织的名称是否正确？
- 检查一下connection-x.yml文件中的peer节点的名称，注意组织名的大小写。
- 检查一下connection-x.yml中关于peers节点的配置:
peer0.Org1.example.com: url: grpcs://127.0.0.1:7051 grpcOptions: ssl-target-name-override: peer0.Org1.example.com grpc.http2.keepalive_time: 15 request-timeout: 120001 hostnameOverride: peer0.Org1.example.com tlsCACerts: pem: | -----BEGIN CERTIFICATE----- x -----END CERTIFICATE-----注意： I. peer的名称：peer0.Org1.example.com II. url指定本机或远程的ip地址，在docker中就能查看到具体的ip地址和端口号。 III. hostnameOverride: peer0.Org1.example.com，将url地址和域名进行绑定，这点很重要（因为证书只能颁发给域名，而实际的调用则一般用ip+端口）

不好意思 ，我又碰到新的问题了。服务启动后可以正常访问页面数据，但是后台会打印如下日志： Caused by: java.net.UnknownHostException: peer1.org2.example.com at java.net.InetAddress.getAllByName0(InetAddress.java:1280) ~[?:1.8.0_181] at java.net.InetAddress.getAllByName(InetAddress.java:1192) ~[?:1.8.0_181] at java.net.InetAddress.getAllByName(InetAddress.java:1126) ~[?:1.8.0_181] at io.grpc.internal.DnsNameResolver$JdkAddressResolver.resolveAddress(DnsNameResolver.java:640) ~[grpc-core-1.23.0.jar:1.23.0] at io.grpc.internal.DnsNameResolver.resolveAll(DnsNameResolver.java:388) ~[grpc-core-1.23.0.jar:1.23.0] at io.grpc.internal.DnsNameResolver$Resolve.resolveInternal(DnsNameResolver.java:256) ~[grpc-core-1.23.0.jar:1.23.0] at io.grpc.internal.DnsNameResolver$Resolve.run(DnsNameResolver.java:213) ~[grpc-core-1.23.0.jar:1.23.0] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) ~[?:1.8.0_181] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) ~[?:1.8.0_181] ... 1 more 2019-12-20 11:25:43.732 [grpc-default-executor-0] WARN PeerEventServiceClient(:) - Received error on PeerEventServiceClient{id: 421, channel: mychannel, peerName: peer1.org2.example.com:10051, url: grpcs://peer1.org2.example.com:10051}, attempts 101.
