wso2 am 网关转发 multipart/form-data post 请求
wso2 am gateway forwarding of multipart/form-data post requests
我正在使用一个演示 API，它接收文件和注释作为 multipart/form-data 输入并显示文件和注释的内容。这是一个示例 HTML，其中 运行 正确 API：
<html>
<body>
<FORM action="http://cgi-lib.berkeley.edu/ex/fup.cgi" method="post">
<P>Choose file: <INPUT type="file" name="upfile">
<p>Note: <INPUT type="text" name="note">
<p><INPUT type="submit" value="Send">
</FORM>
</body>
</html>
现在我正在尝试在 WSO2 APIM 发布者中创建一个托管的 API。下面是我填写的参数：
我正在替换 HTML 的操作以完成 API 我添加的：
<FORM action="http://ec2-52-48-93-41.eu-west-1.compute.amazonaws.com:8280/test" method="post">
但是现在当我 运行 HTML 我从 API 得到以下错误：
cgi-lib.pl: Unknown Content-type: application/x-www-form-urlencoded; charset=UTF-8
似乎 WSO2 网关将请求转发为 application/x-www-form-urlencoded 而不是 mulipart/form-data。
根据下面的讨论我试着注释掉
<messageFormatter contentType="multipart/form-data"
class="org.apache.axis2.transport.http.MultipartFormDataFormatter"/>
<messageBuilder contentType="multipart/form-data"
class="org.apache.axis2.builder.MultipartFormDataBuilder"/>
并将它们替换为
<messageFormatter contentType="multipart/form-data"
class="org.wso2.carbon.relay.ExpandingMessageFormatter"/>
<messageBuilder contentType="multipart/form-data"
class="org.wso2.carbon.relay.BinaryRelayBuilder"/>
然后重启了服务器，没有造成任何影响。
任何想法将不胜感激。
我收集的一些日志消息。目标 API 不同，但它也是一个 multipart/form-data API，它会转储它收到的任何内容。
传入请求确实具有内容类型 multipart/form-data，内容长度为 292

默认情况下看起来更新 API 管理器不保留 clients.You 中的某些 header 需要添加以下 属性 http.headers.preserve = Content-Type 在 repository/conf/passthru-http.properties 中以保留 Content-Type header。
只是为了强调 Ajanthan 的回答，为了正确保留 headers，正确的更改是将以下内容添加到 passthru-http.properties
http.headers.preserve=Content-Length,Content-Type
这是 ESB 4.9.0 的新功能，因此没有太多文档，但您可以在此博客中阅读：http://prabu-lk.blogspot.co.il/2015/09/how-to-preserving-http-headers-in-wso2.html
