我正在尝试通过curl（在macOS上为7.62.0）访问Snom D315手机的Web界面，但是我不断收到错误52（CURLE_GOT_NOTHING）：
$ curl --insecure --user admin:password https://172.16.99.61/settings.xml
curl: (52) Empty reply from server
有趣的类事实：
感谢您的帮助！
附注：我已阅读this question的答案，但无济于事。我还通过在Debian上使用不同的D315和curl 7.52.1确认了此行为，并将手机的固件更新为最新版本。
这是curl --trace-ascii --trace-time --insecure --user admin:password https://172.16.99.61/settings.xml的输出：

答案 0 :(得分：1)
现在这很有趣：手动添加function App() {
this.socketConnection = async function() {
var socket = io('http://localhost:8080');
let p = new Promise(function(res, rej) {
socket.on('connect', function() {
if (socket.connected) {
res(socket);
}
})
})
//returns the socket if connected
return await p;
}
}
/*----------------------------------------------------------------------------------------------------------
E V E N T S S C R I P T S
----------------------------------------------------------------------------------------------------------*/
function _(el) {
this.el = el;
this.ev = function(e, callback) {
switch (arguments.length) {
case 2:
{
this.el.addEventListener(e, callback);
break;
}
}
return this;
}
}
function id(a) {
return new _(document.getElementById(a))
}
function cl(a) {
return new _(document.getElementsByClassName(a))
}
function tg(a) {
return new _(document.getElementsByTagName(a))
}
function qs(a) {
return new _(document.querySelector(a))
}
function qa(a) {
return new _(document.querySelectorAll(a))
}
/*----------------------------------------------------------------------------------------------------------
C O D E
----------------------------------------------------------------------------------------------------------*/
function ScrapJobs(st) {
var _this = this;
var socket = st;
socket.on("Hi", function() {
console.log("I am called from server");
})
this.attachListeners = function() {
qs("#init-scrap").ev("click", _this.startScrapping);
qs("#play-scrap").ev("click", _this.playScrapping);
qs("#pause-scrap").ev("click", _this.pauseScrapping);
qs("#stop-scrap").ev("click", _this.stopScrapping);
}
this.startScrapping = function() {
console.log("I am clicked");
console.log(st.id);
st.emit("Nady");
}
}
/*----------------------------------------------------------------------------------------------------------
I N S T A N T I A T E A P P
----------------------------------------------------------------------------------------------------------*/
window.onload = function() {
if (document.readyState == 'complete') {
var app = new App();
app.init("scrap_jobs").then(function() {
app.attachListeners().then(function() {
app.socketConnection().then(function(sock) {
new ScrapJobs(sock).attachListeners();
})
})
});
}
}标头可以使所有工作正常：
Connection: keep-alive如果没有它，它就不会：
$ curl -sSL -D - -o /dev/null --insecure -H 'Connection: keep-alive' --user admin:xxxxx https://172.16.99.61/settings.xml
