camel with netty4-http - EncoderException(camel with netty4-http - EncoderException)

 我正在使用带有netty4-http的camel 2.14.0，我得到以下异常。 
 

 场景是这样的：我有一个发送请求的路由，等待响应（inOut），然后发送另一个请求。 第一个请求有效，然后第二个请求失败。 
 

 另外，如果我在失败后迅速做到这一点 - 第一个请求也将失败。 
 

 在调试一下（HttpObjectEncoder） - 我看到在工作流程中请求的状态是：state = ST_INIT（0）并且在失败的请求中是：ST_CONTENT_NON_CHUNK（1）当导致非法状态时的类型消息是HttpMessage 
 

 这是一个错误还是我可以配置什么来修复它？

I'm using camel 2.14.0 with netty4-http and I get the following exception.
 

the scenario is this: I have a route that sends a request, waits for the response (inOut) and then sends another request. the first request works, and then the second one fails.
 

also, if I do it quickly enough after the failure - the first request will also fail.
 

while debugging a bit (HttpObjectEncoder) - I saw that in the working flow the state of the request is: state = ST_INIT (0) and in the request that failed it is: ST_CONTENT_NON_CHUNK (1) which causes the illegal state when the type of message is HttpMessage
 

is this a bug or is there anything I can configure to fix it?

最满意答案

 你遇到的问题的原因是由于范围界定。 具体来说， forEach this内部不再绑定到Vue实例。 为了解决这个问题，请尝试在进入循环之前将参考存储在变量中，如下所示： 
 

select_rowse: function () {
    this.deselect_rows();
    var this_vue_instance = this;
    this.get_rows().forEach(function (entry) {
        this_vue_instance.selectedRows.push(entry.id);
    });
}

 

 一般来说，您应尽可能避免使用vm.$data 。 尤其是，如果您有多个对整个代码中散布的变量的引用，并且您需要重命名该变量，而this将保持一致，则会遇到问题。 如果绝对必要，只能使用变量引用，这应该是不常见的。 

The reason you run into the issue you're having is due to scoping. Specifically, this inside of the forEach is no longer bound to the Vue instance. In order to resolve this problem, try storing the reference in a variable prior to entering the loop, like in the following:
 

select_rowse: function () {
    this.deselect_rows();
    var this_vue_instance = this;
    this.get_rows().forEach(function (entry) {
        this_vue_instance.selectedRows.push(entry.id);
    });
}

 

In general, you should try to avoid using vm.$data whenever possible. In particular, you will run into issues if you have multiple references to the variable scattered throughout your code and if you ever need to rename the variable, whereas this will remain consistent. Only use a variable reference if absolutely necessary, which should be infrequent.
