Question

我使用Camel-http4，因为我只需要一个制作人，而不是公开网络服务。我只需要将文件推送到HTTP服务器，因此这是一个客户端实现。我面临的问题是尝试发布返回错误。

CamelHttpResponseCode = 403，CamelHttpResponseText =禁止

{＆＃34;时间戳＆＃34;：＆＃34; 2018-05-03T20：36：20.571＆＃34;＆＃34; traceId＆＃34;：＆＃34;＆＃34;，＆＃34;路径＆＃34;：＆＃34; [POST] https://apm-query-svc-prod.apm-api.com/v2/t_series/upload%2520?throwExceptionOnFailure=false＆＃34;，＆＃34;错误＆＃34;：[{＆＃34; httpStatusCode＆＃34;：＆＃34; FORBIDDEN＆＃34;，＆＃34;代码＆＃34;：＆＃34; FORBIDDEN＆＃34;，＆＃34; message＆＃34;：＆＃34;无法解析多部分servlet请求;嵌套异常是java.io.IOException：org.apache.tomcat.util.http.fileupload.FileUploadException：请求被拒绝，因为没有找到多部分边界＆＃34;，＆＃34; detail＆＃34;：null，＆＃ 34;的requestId＆＃34;：空}]}

问题，有没有办法用Camel-HTTP4做到这一点？怎么做/可以这样做？谢谢!!!

这是路线

<route 
    id="core.pr.upload.route"
    autoStartup="false" >
    <from uri="{{uploadEntranceEndpoint}}" />
    <process ref="customerEntitesProcessor" />
    <process ref="customerTokenProcessor" />
    <process ref="uploadProcessor" />
    <setHeader headerName="CamelHttpUri">
        <simple>${header.UPLOADURL}?throwExceptionOnFailure=false</simple>
    </setHeader>
    <setHeader headerName="CamelHttpMethod">
        <constant>POST</constant>
    </setHeader>
    <to uri="http4://apm-query-svc-prod.app-api.aws-usw02-pr.io:443/v2/t_series/upload?throwExceptionOnFailure=false" />
    <log message="After POSTING FILE: ${body}" loggingLevel="INFO"/>    
    <to uri="{{afteruploadLocation}}" />
</route>

这是类，我只需设置标题，并使用Exchange.HTTP_URI提供的URI覆盖URI。

公共类UploadProcessor实现Processor {

private static final Logger LOG = LoggerFactory.getLogger(UploadProcessor.class);

@Override
public void process(Exchange exchange) throws Exception {

    LOG.info("Entering Upload Processor ..." );

        final String tenant = (String)exchange.getIn().getHeader("TENANT");
        final String token = (String)exchange.getIn().getHeader("TOKEN");
        final String uploadUrl = (String)exchange.getIn().getHeader("UPLOADURL");
        final String custKey = (String)exchange.getIn().getHeader("CUSTKEY");

        LOG.info("TENANT: " + tenant);
        LOG.info("TOKEN: " + token);
        LOG.info("UPLOADURL: " + uploadUrl);
        LOG.info("CUSTKEY: " + custKey);

        LOG.info("Uploading File for CustKey: " + custKey + " and Tenant: " + tenant);          

        StringBuilder authHeader = new StringBuilder("Bearer "); 
        authHeader.append(token);           
        LOG.info("Authorization: " + authHeader.toString());

        exchange.setProperty("CamelCharsetName", "UTF-8");  //"CamelCharsetName" Exchange.CHARSET_NAME
        exchange.getIn().setHeader("CamelHttpCharacterEncoding", "UTF-8");   //"CamelHttpCharacterEncoding" Exchange.HTTP_CHARACTER_ENCODING
        exchange.getIn().setHeader("CamelAcceptContentType", "application/json");  //"CamelAcceptContentType" Exchange.ACCEPT_CONTENT_TYPE
        exchange.getIn().setHeader("CamelHttpUri", uploadUrl);  //"CamelHttpUri" Exchange.HTTP_URI
        exchange.getIn().setHeader("CamelHttpMethod", "POST");  //"CamelHttpMethod" Exchange.HTTP_METHOD
        exchange.getIn().setHeader("x-ge-csvformat", "ODB");
        exchange.getIn().setHeader("Tenant", tenant);
        exchange.getIn().setHeader("Content-Type", "multipart/form-data");  //"Content-Type" ; boundary=
        exchange.getIn().setHeader("Authorization", authHeader.toString());
        LOG.info("Exiting Upload Processor: Finish " );
    }

}

这是我的第一个HTTP介绍，不熟悉多部分边界，我希望有一种简单的解决方案。 :)谢谢!!!

解决方案根本不困难，这是最终根据拉尔夫的答案。谢谢大家！困难的部分是找到导入包并且它具有依赖性。添加到POM

CAMEL HTTP4发布请求被拒绝，因为找不到多部分边界
