沒有錯誤,沒有迴應我的客戶。我message.proto:NodeJs沒有響應gRPC服務器
syntax = "proto3";
message TstCoordinates {
required int32 id = 1;
required string firstname = 2;
required string lastname = 3;
required string email = 4;
required string areacode = 5;
required string phone = 6;
required string extension = 7;
}
message TstId {
required int32 id = 1;
}
message Empty {}
service TstService{
rpc SendCoordinates (TstId) returns (TstCoordinates);
rpc List (Empty) returns (TstCoordinates);
}
我GRPC服務器:
'use strict';
const fs = require('fs');
const grpc = require('grpc');
const serviceDef = grpc.load("message.proto");
const PORT = 7777;
const cacert = fs.readFileSync('certs/ca.crt'),
cert = fs.readFileSync('certs/server.crt'),
key = fs.readFileSync('certs/server.key'),
kvpair = {
'private_key': key,
'cert_chain': cert
};
const creds = grpc.ServerCredentials.createSsl(cacert, [kvpair]);
var tstcoordinates = [
{
id: 1,
firstname: "Bill",
lastname: "Williams",
email: "[email protected]",
areacode: "444",
phone: "555-1212",
extension: "378"
},
{
id: 2,
firstname: "Happy",
lastname: "Golucky",
email: "[email protected]",
areacode: "444",
phone: "555-1212",
extension: "382"
}
];
var server = new grpc.Server();
server.addService(serviceDef.TstService.service, {
list: function(call, callback) {
console.log("in list");
callback(null, tstcoordinates[0]);
},
sendCoordinates: function(call, callback) {
console.log("in sendCoordinates");
callback(null, tstcoordinates[1]);
return;
}
});
server.bind(`0.0.0.0:${PORT}`, creds);
console.log(`Starting gRPC server on port ${PORT}`);
server.start();
我的客戶:
'use strict';
const fs = require('fs');
const process = require('process');
const grpc = require('grpc');
const serviceDef = grpc.load("message.proto");
const PORT = 7777;
const cacert = fs.readFileSync('certs/ca.crt'),
cert = fs.readFileSync('certs/client.crt'),
key = fs.readFileSync('certs/client.key'),
kvpair = {
'private_key': key,
'cert_chain': cert
};
const creds = grpc.credentials.createSsl(cacert, key, cert);
const client = new serviceDef.TstService(`hyperledger-devenv:${PORT}`,creds);
console.log("secure connection established with gRPC server");
lst();
snd();
function printResponse(error, response) {
console.log("in printResponse");
if (error)
console.log('Error: ', error);
else
console.log(response);
}
function lst() {
console.log("in list");
client.list({}, function(error, response) {
console.log("in list call");
printResponse(error, response);
});
}
function snd() {
console.log("in snd");
client.sendCoordinates({'id': 1}, function(error, response) {
console.log("in snd call");
printResponse(error, response);
});
}
當我做了一個 「本地主機捲曲:7777」 命令,服務器顯示的SSL握手錯誤,所以我知道它在聽。客戶端顯示:
secure connection established with gRPC server
in list
in snd
而就是這樣。任何一方都沒有錯誤。我嘗試沒有SSL,並得到完全相同的結果。
我的版本: 節點--version v6.9.5
protoc --version libprotoc 2.6.1
NPM --version 3.10.10
任何幫助極大的讚賞。
TIA
我注意到你說'curl localhost:7777'按預期執行SSL握手,但是你構建你的客戶端來連接到'hyperledger-devenv:7777'。你確定解析爲'localhost'嗎?另外,我應該指出,當客戶端構造函數完成時,並不意味着連接已經建立。第一次發出請求時會嘗試連接。 – murgatroid99
