Question

我正在尝试将数据从HttpClient发送到使用嵌入式Jetty的服务器，托管在同一台机器上。以下是我得到的完整堆栈跟踪错误：

此处发生错误，在实例化GZIPInputStream对象的行上：

ServletInputStream bodyInputStream = request.getInputStream();
GZIPInputStream gis = new GZIPInputStream(bodyInputStream);

其中request是HttpServletRequest。

这是我将字符串压缩为gzip的方式：

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();
}

这就是我发送使用HttpClient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);

我很确定我搞砸了什么，但我不确定到底在哪里。谢谢你的帮助。

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Commons FileUpload

将数据从HttpClient发送到嵌入式Jetty时，“不是GZIP格式”异常
