java - Apache Camel如何以 "body"格式提交正文

Question

使用 Apache Camel，我有 Rest 组件。它看起来像:

    <post uri="/body" method="POST">
        <description>Here is post method</description>
        <param name="save" type="body" dataType="string"/>
        <route>
            <process ref="postRedirectProcessor" />
            <to uri="direct:commonRoute" />
        </route>
    </post>

这个端点处理这样的精细请求:

curl -i --data "b=hereisbody" http://localhost:8080/body (works fine, but I don't need it)

(我可以看到它进入了 postRedirectProcessor ，这很好)。但这不是我想要的。我希望它能够处理这样的请求:

curl -i --data "hereisbody" http://localhost:8080/body (doesn't work, causes 405)

我的意思是，“数据”的格式不像像k=v&k2=v2，但它只是字符串，就像示例中的那样(例如- -数据“某事”)。

它会导致异常，它不会进入 postRedirectProcessor。

我想，param type="body" 正如发布的 xml 中那样，可以解决问题，但没有运气。

Curl 默认在 --data 中发送带有 Content-Type: application/x-www-form-urlencoded header 的数据。请参阅How to post raw body data with curl?

x-www-form-urlencoded 必须采用键/值格式 ( specification )。这就是抛出异常的原因。

The name is separated from the value by = and name/value pairs are separated from each other by &.

要发送原始数据，您需要指定另一个Content-Type。

curl -v -i -H "Content-Type: text/plain" --data "hereisbody" http://localhost:8080/body
