我有一个使用XMLHttpRequest对象的Javascript函数,但我一直返回的状态是0.我已经完成了很多搜索,而我所提出的是0是一个未定义的错误并且可能由无数原因引起。因此,我希望你们能在我的代码中发现错误。
function initiateIPP(ID, Token)
{
var POSTRequest = new XMLHttpRequest();
POSTRequest.onreadystatechange = function ()
{
if (POSTRequest.readyState == 4)
{
if (POSTRequest.status == 200)
{
}
else
{
alert("An error has occured, response code = " + POSTRequest.status);
}
}
}
var parameters = "SessionId=" + ID + "&SST=" + Token;
POSTRequest.open("POST", "https://demo.ippayments.com.au/access/index.aspx", true)
POSTRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded")
POSTRequest.send(parameters)
window.open("IPPPage.html");
}
提前致谢。
编辑:我在代码中添加了withCredentials行,但这似乎没有什么区别。 var parameters =" SessionId =" + ID +"& SST =" +令牌; POSTRequest.withCredentials = true; POSTRequest.open(" POST"," https://demo.ippayments.com.au/access/index.aspx",true) POSTRequest.setRequestHeader(" Content-type"," application / x-www-form-urlencoded") POSTRequest.send(参数) window.open(" IPPPage.html&#34);
答案 0 :(得分:2)
“https://demo.ippayments.com.au/access/index.aspx”这应与您的javascript属于同一个域,否则,您应该设置:
Access-Control-Allow-Origin: *
在目标网页的响应标题上获取工作。见http://enable-cors.org/
例如,您可以将以下内容放在目标服务器上的web.config中:
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
</customHeaders>
</httpProtocol>
</system.webServer>
</configuration>

要与https://demo.ippayments.com.au/access/index.aspx的IPPayments页面正确集成,您需要使用Direct Post方法。不使用XMLHttpRequest对象,而是使用HTML表单提交ID和令牌。例如 -
<form action="https://demo.ippayments.com.au/access/index.aspx" method="post">
<input type="hidden" name="SST" value="1243123123123123123"/>
<input type="hidden" name="SessionID" value="53535434535345"/>
<input type="submit" value="submit" />
</form>
