無法將文件上傳到帶有球衣的休息 api

Question

我的 nexus 公開了一個 REST API 來上傳文件。 使用 curl 我可以使用以下命令上傳：

curl -X POST " http://myurl:9086/service/rest/v1/components?repository=ebooks-store " -H "accept: application/json" -H "Content-Type: multipart/form-data" - F "raw.directory=test" -F "raw.asset1=@billet.pdf;type=application/pdf" -F "raw.asset1.filename=billet.pdf"

文檔說只需要 3 個信息： https : //help.sonatype.com/repomanager3/rest-and-integration-api/components-api

raw.directory (String = Destination for upload files (e.g. /path/to/files)) 
raw.assetN  (File   = at least one  Binary asset) 
raw.assetN.filename (String = Filename to be used for the corresponding assetN asset)

所以在我的 java 代碼中，我嘗試使用 Jersey 做同樣的事情：

FileDataBodyPart filePart = new FileDataBodyPart("file", new File("C:\\Users\\tpolo\Documents\\article.pdf"));
        FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
        FormDataMultiPart multipart = (FormDataMultiPart) formDataMultiPart
                .field("format","raw")
                .field("raw.asset1.filename","article.pdf")
                .field("raw.directory", "test")
                .field("raw.asset1","article.pdf")
                .bodyPart(filePart);

        String url = nexusBaseUrl+"v1/components?repository="+repositoryName;
        WebTarget target = client.target(url);
        //Very important to do, we have to register this
        target.register(MultiPartFeature.class);
        final Response response = target.request().post(Entity.entity(multipart, multipart.getMediaType()));

        //Use response object to verify upload success

        formDataMultiPart.close();
        multipart.close();

在我的聯系日志中，我有這個錯誤：

2019-08-22 21:43:32,122+0000 INFO [qtp969575574-7812] admin org.sonatype.nexus.repository.upload.internal.UploadManagerImpl - 上傳組件參數：repository="ebooks-store" format="raw" directory="test" 2019-08-22 21:43:32,122+0000 INFO [qtp969575574-7812] admin org.sonatype.nexus.repository.upload.internal.UploadManagerImpl - 帶參數的資產：file="null" filename=" article.pdf" 2019-08-22 21:43:32,122+0000 INFO [qtp969575574-7812] admin org.sonatype.nexus.repository.upload.internal.UploadManagerImpl - 帶有參數的資產：file="article.pdf" 201 08-22 21:43:32,124+0000 WARN [qtp969575574-7812] admin org.sonatype.nexus.siesta.internal.ValidationErrorsExceptionMapper - (ID 678c48c7-d7fc-437-d7fc-437-feasyd5234org.sonatype.nexus.siesta.internal.ValidationErrorsExceptionMapper) .spi.BadRequestException：RESTEASY003520：質量值格式錯誤。 在 org.jboss.resteasy.core.request.QualityValue.parseAsInteger(QualityValue.java:112) ... 2019-08-22 21:43:32,125+0000 WARN [qtp969575574-7812] admin org.sonatype.nexus .internal.ValidationErrorsExceptionMapper - (ID 678c48c7-d7fc-438d-94ab-df54977fed23) 響應：[500]'FaultXO{id='678c48c7-d7fc-438d-94ab-df54977fs. BadRequestException: RESTEASY003520: 質量值格式錯誤。'}'; 映射自：org.sonatype.nexus.rest.ValidationErrorsException：“2”上缺少必需的資產字段“文件名”

我做錯了什么 ？ 當我僅通過文件名更改 raw.asset1.filename 時，我得到了

2019-08-22 21:48:51,653+0000 INFO [qtp969575574-7831] admin org.sonatype.nexus.repository.upload.internal.UploadManagerImpl - 上傳組件參數：repository="ebooks-store" format="raw" Filename="article.pdf" directory="test" 2019-08-22 21:48:51,653+0000 INFO [qtp969575574-7831] admin org.sonatype.nexus.repository.upload.internal.UploadManagerImpl - 帶參數的資產：文件="null" 2019-08-22 21:48:51,653+0000 INFO [qtp969575574-7831] admin org.sonatype.nexus.repository.upload.internal.UploadManagerImpl - 帶參數的資產：file="article.pdf" 201 08-22 21:48:51,655+0000 WARN [qtp969575574-7831] 管理員 org.sonatype.nexus.siesta.internal.ValidationErrorsExceptionMapper - (ID 2e179b6c-7c6a-486deasys1bb017.org.sonatype.nexus.siesta.internal.ValidationErrorsExceptionMapper) .spi.BadRequestException：RESTEASY003520：質量值格式錯誤。 message='org.jboss.resteasy.spi.BadRequestException: RESTEASY003520: 格式錯誤的質量值。'}'; 映射自：org.sonatype.nexus.rest.ValidationErrorsException：未知組件字段“文件名”，“1”上缺少必需的資產字段“文件名”，“2”上缺少必需的資產字段“文件名”，資產 1 和 2 有相同的坐標

我真的不知道該怎么辦。

如果您有一個 Maven 存儲庫，似乎您必須使用 Maven 值來上傳。 原始對我不起作用。 但這適用於我的 Maven 存儲庫。

import javax.ws.rs.client.ClientRequestContext;
import javax.ws.rs.client.ClientRequestFilter;
import javax.ws.rs.core.MultivaluedMap;
import javax.xml.bind.DatatypeConverter;
import java.io.IOException;
import java.io.UnsupportedEncodingException;

class Authenticator implements ClientRequestFilter
{
    private final String user;
    private final String password;

    Authenticator(String user, String password) {
        this.user = user;
        this.password = password;
    }

    public void filter(ClientRequestContext requestContext) throws IOException {
        MultivaluedMap<String, Object> headers = requestContext.getHeaders();
        final String basicAuthentication = getBasicAuthentication();
        headers.add("Authorization", basicAuthentication);
    }

    private String getBasicAuthentication() {
        String token = this.user + ":" + this.password;
        try {
            return "BASIC " + DatatypeConverter.printBase64Binary(token.getBytes("UTF-8"));
        } catch (UnsupportedEncodingException ex) {
            throw new IllegalStateException("Cannot encode with UTF-8", ex);
