Mule 响应代码 415 映射为带有文件的 Rest 发布失败

Question

我有 curl 命令和 post 操作，如下所示。这在 curl 命令中运行时工作正常。我将其转换为 Mule 代码，如下所示，但有一些问题。

curl -X POST -H "Authorization: bearer 61e888d88-9iu-2b1cd13a3cee" -H "X-ANYPNT-ORG-ID: 34edrf6-77f7-40fd-6c06a7bcf909" -H "X-ANYPNT-ENV-ID: cdf63246-69ed-4fc6-bbd8-" -H "Content-Type: 
multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW" -H "Cache-Control: no-cache" -H -F "file=@C:\myproject\zip\app-test.zip" 
-F "targetId=12345" -F "artifactName=myapp11" "https://anypoint.mulesoft.com/hybrid/api/v1/applications"

骡码：

<set-payload value="file=@C:\project\zip\app-test.zip&amp;targetId=12345&amp;artifactName=myapp11" doc:name="Set Payload"/>
<http:request config-ref="Hybrid" path="v1/applications" method="POST" doc:name="HTTP">

            <http:header headerName="X-ANYPNT-ENV-ID" value="#[flowVars.envId]"/>
            <http:header headerName="Cache-Control" value="no-cache"/>
      </http:request-builder>
</http:request>

Answer 1

在您的 curl 命令中，您指定了 Content-Type: multipart/form-data，但这不太可能是 Mule 用于 HTTP 请求的内容，因为您只是将有效负载设置为字符串（不确定它实际上会默认为什么) - 这是 HTTP 415 - unsupported media type 所暗示的。

要使用multipart/form-data，您应该在发起 HTTP 请求之前将表单元素（即targetId、artifactName 等）添加到出站附件集合中，而不是在有效负载中。

Answer 2

这里是工作的代码。您的 curl 命令是正确的。 这是我所做的： curl -X POST -F "file=@testfile.txt" http://localhost:8081/special/file

如果你使用postman，数据类型应该是form-data。

<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8081" doc:name="HTTP Listener Configuration"/>
<flow name="special-casesFlow">
    <http:listener config-ref="HTTP_Listener_Configuration" path="/special/file" allowedMethods="POST" doc:name="HTTP"/>
    <set-payload value="#[message.inboundAttachments]" doc:name="Retrieval Attachements"/>
    <foreach doc:name="For Each">

        <set-payload value="#[org.apache.commons.io.IOUtils.toByteArray(payload.getInputStream()); ]" doc:name="Convert File Stream To String"/>
        <byte-array-to-object-transformer />
        <object-to-string-transformer doc:name="Object to String"/>
        <logger message="#[payload]" level="INFO" doc:name="Logger"/>
    </foreach>
</flow>
