Camel发送multipart / form-data请求
我有一个应用程序，它发送一个multipart / form-data和一个收到multipart / form-data请求的应用程序。
收货人处理：
InputStreamCache postBody = exchange.getIn().getBody(InputStreamCache.class); MultipartUploadContext mux = new MultipartUploadContext(postBody, exchange.getIn().getHeader("Content-Type",String.class)); Map params = mux.parseRequest(); 解析请求，从Postman / Swagger发送工作正常。 我把骆驼发送器和我的骆驼接收器集成在一起很麻烦。
这是发件人路线：
from("direct:uploadFileToRest").routeId("uploadFileToRest"). process("uploadFileRequestProcessor"). setHeader(Exchange.HTTP_METHOD, simple("POST")). setHeader(Exchange.CONTENT_TYPE, constant("multipart/form-data")). to("myrecieverapp/full_upload"). id("fileUploadRestSending"). log(LoggingLevel.DEBUG, "RESPONSE BODY ${body}"). end();
发件人处理器：
MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder .create() .addTextBody("name", "SomeName") .addBinaryBody("content", array_with_byte_content_here); exchange.getOut().setBody(multipartEntityBuilder.build());
发生以下错误：
No body available of type: java.io.InputStream but has value: org.apache.http.entity.mime.MultipartFormEntity@35315261 of type: org.apache.http.entity.mime.MultipartFormEntity on: Message[ID-VRN26-1529401997491-0-3]. Caused by: No type converter available to convert from type: org.apache.http.entity.mime.MultipartFormEntity to the required type: java.io.InputStream with value org.apache.http.entity.mime.MultipartFormEntity@35315261.
在查找同样的问题之后，我找到了建议将身体更改为：
exchange.getOut().setBody(multipartEntityBuilder.build().getContent());
但是，它会导致接收方出现问题：
the request was rejected because no multipart boundary was found\r\n\tat org.apache.commons.fileupload.FileUploadBase$FileItemIteratorImpl.(FileUploadBase.java:990)\r\n\tat org.apache.commons.fileupload.FileUploadBase.getItemIterator(FileUploadBase.java:310)\r\n\tat org.apache.commons.fileupload.FileUploadBase.parseRequest(FileUploadBase.java:334)\r\n\tat ru.cinimex.abb.fileuploader.util.MultipartUploadContext.parseRequest(MultipartUploadContext.java:29)\r\n\tat ru.cinimex.abb.fileuploader.camel.processors.ValidateFullUploadRequestProcessor.process(ValidateFullUploadRequestProcessor.java:33)\r\n\tat org.apache.camel.processor.DelegateSyncProcessor.process(DelegateSyncProcessor.java:63)\r\n\tat org.apache.camel.processor.RedeliveryErrorHandler.process(RedeliveryErrorHandler.java:548)\r\n\tat
我读过这些post：

但找不到解决方案

您需要使用在MultipartEntityBuilder生成的正确边界设置Content-Type标头。 修改发件人处理器以设置此标头。
HttpEntity resultEntity = multipartEntityBuilder.build(); exchange.getOut().setHeader(Exchange.CONTENT_TYPE, resultEntity.getContentType().getValue()); exchange.getOut().setBody(resultEntity.getContent());
