ESB Mule 3.8.1 CE HTTP 请求抛出 doSelect 错误

Question

我有 Anypoint 6.2.5
Mule 3.8.1 CE
当我试图发送 json 到 Magento2 Api.
我正在使用这样的 http 请求：

<http:request config-ref="HTTP_Request_Configuration" path="/products/attributes" method="POST" doc:name="HTTP">
<http:request-builder>
<http:header headerName="Authorization" value="Bearer xxxx"/>
<http:header headerName="Content-Type" value="application/json"/>
</http:request-builder>
</http:request>

响应超时设置为 10 秒
我收到一个错误：

我真的不知道该如何解决。
我确定发送请求有效 - Magento 中的新属性已正确创建，但显示错误且流程停止。
更多详细信息：

eclipse.buildId=unknown  
java.version=1.8.0_131  
java.vendor=Oracle Corporation  
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=pl_PL  
Command-line arguments:  -os linux -ws gtk -arch x86_64

它在我朋友的电脑上没有问题也没有错误。我的系统上是否缺少某些软件包？

我解决了问题。

您需要从位于 /lib/user 文件夹的 CE 运行时删除名为 async-http-client 的 jar。

在 AnyPointStudio 安装中找到 CE Runtime。是这样的：

"../Eclipse/plugins/org.mule.tooling.server.3.8.1_6.0.0.201612271237/mule/lib/user"

找到并删除提到的jar文件，重启你的AnyPointStudio就可以了。

对于独立运行时，只需从 github 下载最新版本并使用 maven 构建它。
