我有一个只接受带文件上传的POST请求的帖子服务:
@POST
@Path("uploadfile")
@Consumes({ "*/*" })
@Produces({ "*/*" })
public Response uploadFile(@Context UriInfo uri, @Context HttpHeaders httpHeaders, MultipartBody multipartBody);
如果前端客户端设置了“错误”的Content-Type,则会收到415响应错误。使用InInterceptor,我想将消息重新设置为MultipartBody:
@Override
public void handleMessage(Message message) throws Fault {
System.out.println(message);
}
此处消息的类型为org.apache.cxf.message.XMLMessage。如何更改此选项,我的uploadFile
方法将使用MultipartBody接受此请求?
PS: 前端客户端是未知的,无法更改,目前已经发送错误的内容类型......
我尝试过更改内容类型:
@Override
public void handleMessage(Message message) throws Fault {
Map<String,String> map = (Map<String, String>)message.get(Message.PROTOCOL_HEADERS);
message.put(Message.CONTENT_TYPE, "multipart/form-data");
map.put("content-type", "[multipart/form-data]");
message.put(Message.PROTOCOL_HEADERS, map);
}
但后来我得到了:
java.lang.RuntimeException: org.apache.cxf.interceptor.Fault: java.lang.String cannot be cast to java.util.List
at org.apache.cxf.interceptor.AbstractFaultChainInitiatorObserver.onMessage(AbstractFaultChainInitiatorObserver.java:116)
at org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:333)
at org.apache.cxf.transport.ChainInitiationObserver.onMessage(ChainInitiationObserver.java:121)
答案 0 :(得分:0)
好的,我发现我投错了......
Map<String,List> map = (Map<String, List>)message.get(Message.PROTOCOL_HEADERS);
不
Map<String,String> map = (Map<String, String>)message.get(Message.PROTOCOL_HEADERS);
所以现在它有效......
@Override
public void handleMessage(Message message) throws Fault {
Map<String,List> map = (Map<String, List>)message.get(Message.PROTOCOL_HEADERS);
message.put(Message.CONTENT_TYPE, "multipart/form-data");
map.put("content-type", Collections.singletonList("multipart/form-data"));
message.put(Message.PROTOCOL_HEADERS, map);
}
