即时通讯设法编写代码javascript
,使我能够登录到网站。 当我第一次发送http(获取请求)获取登录网页的网站响应正确的我的请求给我一个cookie(登录之前)。 现在我想发送另一个POST
请求中的用户名和密码以及cookie以获得login
身份验证。 问题是,即时消息发送该请求只是与网页源代码相同,它会引发错误(xhr.status
为0)。 什么可能是错的?javascript:使用XMLHttpRequest登录网站
这里是我的代码:
var url = "https://sess.shirazu.ac.ir/sess/Start.aspx";
var username = "myUsername";
var password = "myPassword";
var xhr;
login: function(){
xhr = new XMLHttpRequest();
xhr.withCredentials = true;
xhr.onreadystatechange = (e) => {
if (xhr.readyState !== 4) {
return;
}
if (xhr.status === 200) {
var pageSource = xhr.responseText; //gets the response of the request of the login page
//here is where im hashing the password with the given key in the retrieved page-source
var parser = new DOMParser();
var doc = parser.parseFromString(pageSource, "text/xml");
var RKeyElement = String(doc.getElementById("_RKey"));
var RKey = RKeyElement.substring(RKeyElement.search("value"));
RKey = RKey.substring(RKey.search("\"")+1, RKey.lastIndexOf("\"")); //getting the 32-digit-long _RKey
DoLogin(username, password , '', RKey);
}
else {
Alert.alert("error");
}
};
xhr.open('GET', url, true);
xhr.send(null);
},
}
上面的代码工作好,问题是这个DoLogin()函数:
function DoLogin(iId, iPass, iCode, RKey) {
var Inc = Md5High(RKey, iPass); //this works fine (Hashing the password)
var Request = xhr;
Request.onreadystatechange = (e) => {
if (Request.readyState !== 4) {
return;
}
if (Request.status === 200) {
console.log('success', Request.responseText);
}
else {
console.log('error'); //status is 0 when this occures
}
};
Request.abort();
Request.open('post', "https://sess.shirazu.ac.ir/sess/17610358812"+"/sess/Script/AjaxEnvironment.aspx?Act=MakeMember&Id=" + iId + "&Pass=" + Inc + "&Code=" + iCode, true);
Request.send();
}
