404说明是客户端的问题导致服务器无法处理，https://segmentfault.com/a/11...

建议弃用httpclient，使用HttpURLConnection：

<code>import java.io.ByteArrayOutputStream;
import java.io.DataOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class HttpConnector {
    public static final int TIMEOUT_MS = 10 * 1000;

    public static String performRequest(String url, File file, Map<string string> additionalHeaders) {
        String response = null;
        try {
            HashMap<string string> map = new HashMap<string string>();
            if (additionalHeaders != null)
                map.putAll(additionalHeaders);
            URL parsedUrl = new URL(url);
            HttpURLConnection connection = openConnection(parsedUrl, file);
            for (String headerName : map.keySet()) {
                connection.addRequestProperty(headerName, map.get(headerName));
            }
            int responseCode = connection.getResponseCode();
            if (responseCode == -1) {
                // -1 is returned by getResponseCode() if the response code could not be retrieved.
                // Signal to the caller that something was wrong with the connection.
                throw new IOException("Could not retrieve response code from HttpUrlConnection.");
            }

            String charset = "utf-8";
            String contentEncoding = null;
            String contentType = null;

            for (Map.Entry<string list>> header : connection.getHeaderFields().entrySet()) {
                if (header.getKey() != null) {
                    List<string> headerValueList = header.getValue();
                    if (headerValueList != null && headerValueList.size() > 0) {
                        StringBuffer headerValueSB = new StringBuffer();
                        for (int i = 0; i </string></string></string></string></string></code>

Salin selepas log masuk

调用：String response = HttpConnector.performRequest(uploadUrl, file, null);
