当从Apache HTTP客户端执行多部分请求时HTTP 400
当从Apache HTTP客户端执行多部分请求时HTTP 400

我正在尝试将一个传入Servlet的请求转发到在Tomcat7上运行的JAX-RS的CXF实现中实现的实际后端。
以下是我的代码：
protected void doPost(HttpServletRequest req, HttpServletResponse resp) {
HttpPost postRequest = new HttpPost(targetURL);
if (ServletFileUpload.isMultipartContent(req)) {
ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
List<FileItem> fileItemList = servletFileUpload.parseRequest(req);
MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create();
entityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
for (FileItem item: fileItemList) {
entityBuilder.addPart(item.getFieldName(), new ByteArrayBody(item.get(), ContentType.create(item.getContentType()), item.getName()));
}
postRequest.setEntity(entityBuilder.build());
} else {
if (StringUtils.isNotEmpty(req.getHeader(HttpHeaders.CONTENT_LENGTH)) || StringUtils.isNotEmpty(req.getHeader(HttpHeaders.TRANSFER_ENCODING))) {
InputStreamEntity entity = new InputStreamEntity(req.getInputStream(), Long.parseLong(req.getHeader(HttpHeaders.CONTENT_LENGTH)));
postRequest.setEntity(entity);
}
}
postRequest.setHeader(postRequest.getEntity().getContentType());
postRequest.setHeader(HttpHeaders.AUTHORIZATION, "ACCESS-TOKEN");
try (CloseableHttpClient client = HttpClients.createDefault()) {
HttpResponse response = client.execute(httpRequest);
}
}对于非多部分请求，上面的代码运行时没有问题。然而，每当我尝试多部分请求时，都会得到"HTTP 400 Bad Request“响应。请求也不会传递到实际的实现中(后端没有错误)
HttpResponseProxy{HTTP/1.1 400 Bad Request [X-Frame-Options: DENY, X-Content-Type-Options: nosniff, X-XSS-Protection: 1; mode=block, Access-Control-Allow-Origin: *, Access-Control-Allow-Methods: GET, POST, DELETE, PUT, Access-Control-Allow-Headers: Content-Type, Date: Fri, 21 Jun 2019 01:27:59 GMT, Content-Length: 0, Connection: close] [Content-Length: 0,Chunked: false]}我尝试使用原始边界保留传入的内容类型标头，然后后端抛出以下错误。
Caused by: org.apache.cxf.interceptor.Fault: Couldn't find MIME boundary: ----------------------------282428552532940822247758
at org.apache.cxf.interceptor.AttachmentInInterceptor.handleMessage(AttachmentInInterceptor.java:60)
at org.apache.cxf.jaxrs.ext.MessageContextImpl.createAttachments(MessageContextImpl.java:268)
at org.apache.cxf.jaxrs.ext.MessageContextImpl.get(MessageContextImpl.java:77)你知道我做错了什么吗？

postRequest.setHeader(postRequest.getEntity().getContentType());不要那样做。HttpClient根据封装的Content-Type的属性自动生成请求消息体的HttpEntity头。
