我正在使用 Apache Http Client 上传文件。当我将内容长度设置为不正确的文件大小时。

内容长度标头被文件大小覆盖。从而导致验收测试失败，因为它允许上传文件，因为内容长度等于文件大小。

public class RestClient {
    Client client = null;

    public RestClient() {
        client = Client.create();
        //client.addFilter(new LoggingFilter(System.out));
    }

    public ClientResponse postData(String url, Map headerMap) throws IOException {
        ClientResponse response = null;

        try {
            WebResource webResource = client.resource(url);
            Builder requestBuilder = webResource.getRequestBuilder();
            Iterator it = headerMap.entrySet().iterator();

            while (it.hasNext()) {
                Map.Entry pair = (Map.Entry) it.next();
                requestBuilder = requestBuilder.header(pair.getKey().toString(), pair.getValue());
            }

            if (headerMap.get("filename") != null) {
                ClassLoader cl = getClass().getClassLoader();
                InputStream fileInStream = cl.getResourceAsStream(headerMap.get("filename").toString());
                MessageDigest md = MessageDigest.getInstance("SHA-256");
                requestBuilder = requestBuilder.entity(fileInStream);
            }

            response = requestBuilder.header("Expect", new String("100-continue"))
                    .post(ClientResponse.class);
        } catch (Exception e) {
            e.printStackTrace();
        }

        return response;
    }

    public ClientResponse getData(String url) {
        ClientResponse response = null;

        WebResource webResource = client.resource(url);
        response = webResource.get(ClientResponse.class);

        return response;
    }
}

当前 headermap 具有必需的标头（Content-Length、Content-Type 等）

我可以在没有客户端内部覆盖它的情况下显式设置 Content-Length 吗？任何http客户端都可以。

任何自尊的 HTTP 客户端都应该这样做。HttpURLConnection当然可以。您的测试无效。内容长度必须与传输的实际字节数相匹配。
