我正在使用一个演示API,该API接收文件和注释作为多部分/表单数据输入,并显示文件和注释的内容.这是可以正确运行API的示例HTML:
I am using a demo API which receives a file and note as multipart/form-data input and displays the content of the file and the note. Here is a sample HTML which runs the API correctly:
<html> <body> <FORM action="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发布者中创建托管API.以下是我填写的参数:
Now I'm trying to created a managed API in the WSO2 APIM publisher. Below are the parameters I filled in:
我正在替换HTML的操作,以通过添加的API进行操作:
I'm replacing the action of the HTML to go through the API I added:
<FORM action="ec2-52-48-93-41.eu-west-1pute.amazonaws:8280/test" method="post">但是现在当我运行HTML时,我从API中收到以下错误:
But now when I run the HTML I get the following error from the API:
cgi-lib.pl: Unknown Content-type: application/x-www-form-urlencoded; charset=UTF-8好像WSO2网关将请求转发为application/x-www-form-urlencoded而不是mulipart/form-data.
Seems like the WSO2 gateway forwarded the request as application/x-www-form-urlencoded rather than as mulipart/form-data.
基于以下讨论使用WSO2 API管理员?我试图将其注释掉
Based on the following discussion multipart form data file upload using WSO2 API manger ? I tried to comment out
<messageFormatter contentType="multipart/form-data" class="org.apache.axis2.transport.http.MultipartFormDataFormatter"/> <messageBuilder contentType="multipart/form-data" class="org.apache.axis2.builder.MultipartFormDataBuilder"/>并替换为
<messageFormatter contentType="multipart/form-data" class="org.wso2.carbon.relay.ExpandingMessageFormatter"/> <messageBuilder contentType="multipart/form-data" class="org.wso2.carbon.relay.BinaryRelayBuilder"/>然后重新启动服务器,但没有造成任何影响.
Then restarted the server, but it did not cause any impact.
任何想法都会受到赞赏.
Any ideas will be appreciated.
我收集了一些日志消息.目标API是不同的,但它也是一个多部分/表单数据API,它会转储接收到的所有内容.
Some log messages that I collected. The target API is different, but it is also a multipart/form-data API which dumps whatever it receives.
传入请求确实具有内容类型multipart/form-data,内容长度为292

仅强调Ajanthan答案,为了正确保留标头,正确的更改是将以下内容添加到passthru-http.properties
Just to stress Ajanthan answer, in order to preserve the headers correctly, the correct change would be to add the following to passthru-http.properties
http.headers.preserve=Content-Length,Content-Type这是ESB 4.9.0的新功能,因此没有太多文档记录,但是您可以在以下博客中阅读它: prabu-lk.blogspot.co.il/2015/09/how-to-preserving-http-headers -in-wso2.html
It's a new feature of ESB 4.9.0, so not much documented, but you can read about it in this blog: prabu-lk.blogspot.co.il/2015/09/how-to-preserving-http-headers-in-wso2.html
