我有一个带有ssl/https并由htaccess保护的家庭服务器。我已经以一种方式配置了服务器，如果我访问
https://USER:PASSWORD@subdomain.domain.con/room_1/switch_1/set.php?state=0
房间 1 的灯熄灭了。此外，页面返回的当前状态非常简单，例如
<html>
0
</html>
现在我正在尝试使用 QML 构建一个客户端应用程序（因为它将支持多个平台窗体）。
任务应该是按下一个按钮，应用程序"拨入"到
https://USER:PASSWORD@subdomain.domain.con/room_1/switch_1/set.php?state=0
并在之后将 PHP 页面读出为纯字符串。
我从这里尝试了XMLHttpRequest，例如
var req = new XMLHttpRequest();
req.open("POST", "http://www.xxxxxxxxx.com/test/test.php");
req.onreadystatechange = function() {
if (req.readyState == XMLHttpRequest.DONE) {
// what you want to be done when request is successfull
}
}
req.onerror = function(){
// what you want to be done when request failed
}
req.send("name=xxx&email=xxx&message=xxx");
在按钮单击事件中，但没有响应。
问题哪种方式可以实现此任务???
求解忽略自动签名的 SSL 证书以及 XMLHttpRequest 的一些基础知识。
要处理自签名（或任何）SSL CA，请执行以下操作：
将这些包含添加到主.cpp
#include <QSslConfiguration>
#include <QSslSocket>
将这些行添加到 main（） 的开头
QSslConfiguration config = QSslConfiguration::defaultConfiguration();
config.setPeerVerifyMode(QSslSocket::VerifyNone);
QSslConfiguration::setDefaultConfiguration(config);
要通过 htaccess 授权读取文件/响应，请执行以下操作：
该行"xhr.setRequestHeader（ 'Authorization'， 'Basic ' + Qt.btoa（tb_user.text + '：' + tb_pw.text） ）"是正确设置用户和密码的关键。
function getSome() {
txtLog.log("getSome executed");
var xhr = new XMLHttpRequest()
xhr.open( 'POST', 'https://subdomain.domain.con/room_1/switch_1/set.php?state=0', true)
xhr.setRequestHeader( 'Authorization', 'Basic ' + Qt.btoa(tb_user.text + ':' + tb_pw.text) )
xhr.withCredentials = true
xhr.onreadystatechange = function() {
console.log( xhr.status, xhr.statusText )
console.log( xhr.responseText , xhr.responseText )
}
xhr.send()
}
所有 Java 用户的旁注：
昨天我创建了一个Android Java应用程序，它可以很好地处理任务。自签名 SSL CA 的问题在私有 void trustEveryone（） 函数中处理。
