如何使用 Apache Camel 进行授权？

我必须发出 POST 请求

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 是一个包含登录名和密码的 JSON 文件。然后我有两个选择：将令牌作为“Authorization：TOKEN”放入将来请求的标头中，或者将其放入 cookie 中并发出其他请求。我怎样才能用 Apache Camel 做到这一点？如何接收 HTTP 响应？我把令牌放在哪里？现在我有：

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();

} 我在 ./data/inbox 中有 auth.json 文件

I have to make a POST request

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

, 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();

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

由于您在 Apache Camel 邮件列表上发布了相同的问题，我提供了答案在那里。

总结一下：只需在发送 http 请求之前在路由中调用 setHeader("Authorization",constant("622cee5f8c99c81e87614e9efc63eddb")) 即可。 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，您不需要在路由中提供常量令牌，您可以使用 Camel 表达式或处理器。

您的完整路线将类似于：

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"); 
 }

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

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.

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"); 
 }
