我在测试HTTPS服务器时遇到了一个问题。
我使用jasmine编写了一个测试用例，我面临的问题是，当我在测试用例中评论一段代码时，测试用例失败，如果我启用该代码，测试用例就会通过。
以下是我为网络服务器编写的代码：
网络-server.js
var https = require('https');
var fs = require('fs');
var jsonFile = require('jsonfile');
var util = require("util");
const events = require('events');
var fileName = 'resource.json';
const contentType = "application/xml";
const port = 443;
var Options = {
key: fs.readFileSync('./key1'),
cert: fs.readFileSync('./Cert1')
};
var webServerIface = function (){
var server = https.createServer(Options, (request, response) => {
console.log('request ', request.url,request.method);
jsonFile.readFile(fileName, (err, jsonData) => {
if (err) throw err;
this.emit(jsonData[request.url][request.method],response);
});
})
server.listen(port, "0.0.0.0");
// Error handling
server.on('error',(err) => {
throw err;
});
this.on('processClassRequest', (response) => {
var xmlHeader = "<?xml version=\"1.0\" encoding=\"utf-8\"?>";
var infoRootNode = "<infoUriType>";
var infoMacIdNode = "<macid>";
var infoMacIdClosingNode = "</macid>";
var infoRootClosingNode = "</infoUriType>";
var macAddress = "DEADBEEFFEED";
console.log("Got a processClassRequest request: ");
var xmlReturn = xmlHeader + infoRootNode + infoMacIdNode + macAddress
+ infoMacIdClosingNode +infoRootClosingNode;
response.writeHead(200, { 'Content-Type': contentType });
response.write(xmlReturn);
response.write("OK");
response.end();
});
webServerIface.prototype.shutDown = function () {
server.close(() => {
console.log('All connections are ended:server is finally closed');
});
}
}
util.inherits(webServerIface, events.EventEmitter);
module.exports = webServerIface;
resource.json
{
"/class/double/triple" : {
"GET" : "processClassRequest"
}
}
测试上述HTTPS服务器的代码：
WebServer_spec.js
const WebServer = require('../web-server.js');
var https = require('https');
var class_info = {
hostname: '172.18.1.45',
rejectUnauthorized: false,
port: 443,
path: '/class/double/triple',
method: 'GET'
};
describe("Web Server Test Suite", function() {
var WebServerHandle;
it("should start the secure web server", function() {
console.log("Starting Web Server");
this.webserverhandle = new WebServer();
WebServerHandle = this.webserverhandle;
});
it("should send http request to secure web-server", function(done) {
var req = https.request(class_info, function(res) {
res.setEncoding('utf8');
//If I uncomment below lines then test succeeds
/*res.on('data', function (chunk) {
console.log('Response: ' + chunk);
});*/
res.on('end', chunk => {
expect(res.statusCode).toBe(200);
done();
});
});
req.end();
});
it("should stop the secure web server", function() {
WebServerHandle.shutDown();
});
});
输出：

如果我取消注释res.on('data', function (chunk) { console.log('Response: ' + chunk); });，测试成功。
我不知道如果我做错了什么。
答案 0 :(得分：0)
在搜索了一下并通过nodejs文档后，我发现HTTP / HTTPS服务器在从客户端获得新的连接请求时会创建可写和可读的流。
当有些数据需要写入steam时，服务器会发出data事件，当且仅当流上消耗了所有数据时才会发出end事件。
