用泽西发送ByteArrayOutputStream

Question

我试图用Jersey发送一个带有POST的ByteArrayOutputStream压缩文件。

Client client = Client.create();
client.resource(url);

ClientResponse response = webResource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(ClientResponse.class, myBaosObject.toByteArray());

<dependency>
  <groupId>com.sun.jersey</groupId>
  <artifactId>jersey-client</artifactId>
  <version>1.9.1</version>
 </dependency>

Answer 1

我能做到这一点是通过做：

File file = null;
    try {
        // Transform baos into file
        InputStream is = new ByteArrayInputStream(baos.toByteArray());

        file = File.createTempFile("file ", "zip");
        FileUtils.copyInputStreamToFile(is, file);

        HttpClient httpclient = HttpClientBuilder.create().build();
        HttpPost httpPost = new HttpPost(url);

        // Send file as part of body
        FileBody uploadFilePart = new FileBody(file);
        MultipartEntity reqEntity = new MultipartEntity();
        reqEntity.addPart("file", uploadFilePart);
        httpPost.setEntity(reqEntity);

        HttpResponse response = httpclient.execute(httpPost);
        return response.toString();

    } finally {
        if (file != null) {
            file.delete();
        }
    }

我必须补充以下内容：

<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.5</version>
</dependency>
