Java &引用；不是GZIP格式的”；从HttpClient向Jetty embedded发送数据时发生异常

我试图将数据从HttpClient发送到使用Jetty embedded的服务器，该服务器托管在同一台机器上。以下是我从错误中获得的完整堆栈跟踪：

其中

request

是HttpServletRequest

这是我如何将字符串压缩到gzip的：

public static byte[] gzip(String content) {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();

    try (GZIPOutputStream gzos = new GZIPOutputStream(baos)) {
        gzos.write(content.getBytes(StandardCharsets.UTF_8));
    } catch (IOException e) {
        e.printStackTrace();
    }

    return baos.toByteArray();
}

这就是我使用HttpClient发送的方式：

byte[] result = Utils.gzip(pagesJson);

HttpClient client = HttpClients.createDefault();
HttpPost httpPost = new HttpPost("http://" + serverHost + "/upload");

MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addBinaryBody("pages", result, ContentType.DEFAULT_BINARY, "pages.bin");
HttpEntity multipart = builder.build();
httpPost.addHeader(HTTP.CONTENT_ENCODING, "gzip");
httpPost.setEntity(multipart);

HttpResponse response = client.execute(httpPost);

我很确定我把事情搞砸了，但我不确定具体在哪里。谢谢您的帮助。

如果您只想发送gzip文件，则无需设置标题

httpPost.addHeader(HTTP.CONTENT_ENCODING, "gzip");

在服务器端，您还需要处理多部分请求，为此，您可以使用

httpPost.addHeader(HTTP.CONTENT_ENCODING, "gzip");
