如何使用Apache Camel授权? [英] How to authorize using Apache Camel?

问题描述

我必须发出POST请求

I have to make a POST request

curl -X POST --data-binary @auth.json http://somehost.com/auth
{
    "response": {
        "status": "OK",
        "token": "622cee5f8c99c81e87614e9efc63eddb"
    }
}

，这将返回带有令牌的JSON响应.auth.json是带有登录名和密码的JSON文件.然后，我有两个选择:将令牌放在将来的请求中作为"Authorization:TOKEN"的标头中，或者将其放在cookie中并发出其他请求.如何使用Apache Camel做到这一点?如何接收HTTP响应?我在哪里放令牌?现在我有:

, and this will return a JSON response with the token. auth.json is a JSON file with login and password. I then have two options: put the token in the header in future requests as "Authorization: TOKEN", or put it in a cookie and make other requests. How can I do it with Apache Camel? How can I receive HTTP response? Where do I put the token? Now I have:

public static void main(String args[]) throws Exception {
    CamelContext context = new DefaultCamelContext();
    context.addRoutes(new RouteBuilder() {
        public void configure() {
            from("file:data/inbox?noop=true")
            .to("http://somehost.com/auth");
        }
    });
    context.start();
    Thread.sleep(10000);
    context.stop(); 

}而且我在./data/inbox

} and I have the auth.json file in ./data/inbox

推荐答案

由于您在Apache Camel邮件列表中发布了相同的问题，所以我提供了

Since you posted the same question on the Apache Camel mailing list I've provided an answer there.

总结:在发送http请求之前，只需在路由中调用 setHeader("Authorization"，constant("622cee5f8c99c81e87614e9efc63eddb")).Camel会自动将此标头转换为特定于传输的(在本例中为HTTP)标头.当然，您无需在路由中提供恒定的令牌，可以使用Camel

To summarize: Just call setHeader("Authorization", constant("622cee5f8c99c81e87614e9efc63eddb")) in your route before sending the http request. Camel will automatically translate this header to a transport specific (in this case HTTP) header. Of course you don't need to provide a constant token in your route, you can dynamically calculate or lookup the token by using a Camel expression or processor.

您的完整路线将类似于:

Your complete route will look something like:

context.addRoutes(new RouteBuilder() { 
    public void configure() { 
            from("file:data/out?fileName=filename.json&noop=true") 
            .setHeader("Authorization", constant("mytoken")) 
            .to("http://somehost.com/auth"); 
 }
