ESB Mule 3.8.1 CE HTTP 请求抛出 doSelect 错误

Question

我有 Anypoint 6.2.5
骡 3.8.1 CE
当我尝试将 json 发送到 Magento2 Api 时。
我使用这样的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
我有一个错误：

我真的不知道如何解决它。
我确信发送请求有效 - Magento 中的新属性已正确创建，但出现错误并且流程已停止。
更多细节：

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运行没有问题，也没有错误。我的系统上是否缺少某些软件包？

Answer 1

我解决了问题。

您需要从位于 /lib/user 文件夹的 CE 运行时中删除一个名为 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。

Answer 2

在 https://www.mulesoft.org/jira/browse/MULE-8989 处已经有一个 错误 MULE-8989 已在 Mule 运行时 3.8.2 https://docs.mulesoft.com/release-notes/mule-3.8.2-release-notes 中修复
尝试升级我们的 mule 运行时
