使用PUT请求Java将文本文件上载到Swagger

我使用ApacheHttpConnection将带有PUT请求的文本文件发送到Swagger上的服务器主机。似乎我遗漏了一些东西，因为作为响应，我得到了“内部服务器错误”。 客户端代码：

    String url = "http://xxx.xxx.xx.xx:XXXX/warehouse-ui/api/v2/external-file/IMPORT_RATIO?businessUnit=MBA&sourceSystem=AVALOQ_MBA&effectiveFrom=2011-12-21&effectiveTo=MAX&threshold=WARNING";       
    String encoding = Base64.getEncoder().encodeToString((usrPassPair).getBytes());

    InputStream is = new FileInputStream(myLocalFile);
    HttpPut request = new HttpPut(url);
    HttpEntity entity = MultipartEntityBuilder.create().addBinaryBody("test", is, ContentType.create("multipart/form-data"), "asd.txt").build();
    request.setHeader("Authorization", "Basic " + encoding);
    request.setEntity(entity);

    HttpClient client = HttpClientBuilder.create().build();
    HttpResponse response = client.execute(request);
    int code = response.getStatusLine().getStatusCode()

服务器站点上的代码（招摇过市）：

@Path（“/{descriptor}”）
@放
@使用（{MediaType.MULTIPART\u FORM\u DATA}）
@ApiOperation（position=1，value=“根据给定的描述符在指定的生效日期上载文件并传输数据。传输是同步完成的。”）
@生成（“应用程序/json”）
公共响应上载文件(
@QueryParam（“businessUnit”）@ApiParam（required=true）字符串businessUnitName，
@QueryParam（“sourceSystem”）@ApiParam（required=true，value=“源系统”）字符串sourceSystemName，
@PathParam（“描述符”）@ApiParam（required=true，value=“文件的描述符”）字符串描述符，
@QueryParam（“effectiveFrom”）@ApiParam（required=true，value=“ISO格式的日期，例如2011-12-21”）字符串effectiveFromString，
@QueryParam（“effectiveTo”）@ApiParam（value=“ISO格式的日期”或“MAX”。例如，2011-12-21”，defaultValue=“MAX”）字符串effectiveToString，
@ApiParam（value=“file to upload”，required=true）@FormDataParam（“file”）InputStream InputStream，
@ApiParam（value=“file detail”，required=true）@FormDataParam（“file”）formdatacontentdispositionfiledetail，
@QueryParam（“阈值”）@ApiParam（必需=true，value=“记录阈值”，allowableValues=“消息，通知，警告，错误”，defaultValue=“警告”）严重性阈值）
抛出IOException、Persistence.Exception、BusinessException、ConfigurationException{
ExternalFile ExternalFile=new VirtualExternalFile（fileDetail.getFileName（），ByteStreams.toByteArray（inputStream））；
TaskExecutionJob TaskExecutionJob=prepareTransfer（businessUnitName、sourceSystemName、descriptor、，
EndPointHelper.getEffectivePeriodFrom（effectiveFromString，effectiveToString），外部文件，阈值）；
返回EndPointHelper.createResponseFor（taskExecutionJob.executeSynchronous（））；

是否有我未包含的参数导致了此错误？

我想如果有人遇到类似问题，我会发布我的工作答案，也许有人更了解REST体系结构，可以解释为什么需要这样做：

    URIBuilder builder = new URIBuilder()
            .setScheme("http")
            .setHost("localhost:9090")
            .setPath("warehouse-ui/api/v2/external-file/"+context.get("descriptor").toString())
            .setParameter("businessUnit", context.get("businessUnit").toString())
            .setParameter("sourceSystem", context.get("sourceSystem").toString())
            .setParameter("effectiveFrom", context.get("effectiveFrom").toString())
            .setParameter("effectiveTo", context.get("effectiveTo").toString())
            .setParameter("threshold", context.get("threshold").toString());

    String encoding = Base64.getEncoder().encodeToString((usernamePasswordPair).getBytes());
    File isF = new File(pathToFile);
    FileInputStream fis = null;
    fis = new FileInputStream(isF);

    HttpPut request = new HttpPut(builder.toString());
    HttpEntity entity = MultipartEntityBuilder.create().addPart("file", new InputStreamBody(fis, isF.getName())).build();
    request.setHeader("Authorization", "Basic " + encoding);
    request.setEntity(entity);
    HttpClient client = HttpClientBuilder.create().build();
    HttpResponse response = client.execute(request);
    int code = response.getStatusLine().getStatusCode();
    System.out.println(code);
    System.out.println(response.getStatusLine().getReasonPhrase());

这是从Talend tJava组件粘贴的代码，所以在代码中您可能需要处理异常

    URIBuilder builder = new URIBuilder()
            .setScheme("http")
            .setHost("localhost:9090")
            .setPath("warehouse-ui/api/v2/external-file/"+context.get("descriptor").toString())
            .setParameter("businessUnit", context.get("businessUnit").toString())
            .setParameter("sourceSystem", context.get("sourceSystem").toString())
            .setParameter("effectiveFrom", context.get("effectiveFrom").toString())
            .setParameter("effectiveTo", context.get("effectiveTo").toString())
            .setParameter("threshold", context.get("threshold").toString());

    String encoding = Base64.getEncoder().encodeToString((usernamePasswordPair).getBytes());
    File isF = new File(pathToFile);
    FileInputStream fis = null;
    fis = new FileInputStream(isF);

    HttpPut request = new HttpPut(builder.toString());
    HttpEntity entity = MultipartEntityBuilder.create().addPart("file", new InputStreamBody(fis, isF.getName())).build();
    request.setHeader("Authorization", "Basic " + encoding);
    request.setEntity(entity);
    HttpClient client = HttpClientBuilder.create().build();
    HttpResponse response = client.execute(request);
    int code = response.getStatusLine().getStatusCode();
    System.out.println(code);
    System.out.println(response.getStatusLine().getReasonPhrase());
