我正在尝试从 Https 网址下载文件，该文件需要进行基本身份验证。我正在使用HTTP4 我想从网址下载 - https://ebc.cybersource.com/ebc/DownloadReport/xxx.csv?authMethod=Basic&authUsername=scott&authPassword=tiger
下载文件后，我需要将其保存到文件夹中。这是我的代码的样子
from(xxx)
.to("http4://ebc.cybersource.com/ebc/DownloadReport/xxx.csv?authMethod=Basic&authUsername=scott&authPassword=tiger")
.to("file:target/messages/download");
这是我得到的错误 -

现在文档说我需要使用HttpContext，
public class HttpContextFactory {
private String httpHost = "localhost";
private String httpPort = 9001;
private BasicHttpContext httpContext = new BasicHttpContext();
private BasicAuthCache authCache = new BasicAuthCache();
private BasicScheme basicAuth = new BasicScheme();
public HttpContext getObject() {
authCache.put(new HttpHost(httpHost, httpPort), basicAuth);
httpContext.setAttribute(ClientContext.AUTH_CACHE, authCache);
return httpContext;
}
// getter and setter
}
我尝试过，但我仍然遇到错误。
更新 我实际上是使用石英调度程序来触发
from("quartz2://foo?cron=0/2+*+*+?+*+MON-FRI").multicast().stopOnException().to("direct:downLoadFile");
from("direct:downLoadFile")
.to("http4://ebc.cybersource.com/ebc/DownloadReport/2015/04/16/us_voip/us_voip.au.response.ss.csv?authMethod=Basic&authUserName=xxxx&authPassword=yyyy")
.log("File Downloaded");
当我运行时，我收到以下错误。

最终更新：已解决 感谢@Claus Ibsen提供了正确的组件。我只需使用https4而不是http。请注意，骆驼文档中缺少此信息。这是最终代码，从网站下载文件并保存在目标/下载文件夹中。

public class SchedulerRoute extends RouteBuilder {
//TODO Move this to properties file
String userCredentials ="userName:Password";

你不能从http4开始，因为异常告诉你，你需要一个计时器或什么来触发路线
{{1}}
在此示例中，计时器每隔5秒触发一次。
