我的功能

    public static String postFile(String url,String fileName, String userName) throws Exception {

    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(url);
    MultipartEntityBuilder builder = MultipartEntityBuilder.create();
    builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

    final File file = new File(fileName);

    ContentBody cfile=new FileBody(file);
    builder.addPart("file",cfile);
    builder.addTextBody("userName", userName);

    final HttpEntity yourEntity = builder.build();

    class ProgressiveEntity implements HttpEntity {
        @Override
        public void consumeContent() throws IOException {
            yourEntity.consumeContent();
        }
        @Override
        public InputStream getContent() throws IOException,
                IllegalStateException {
            return yourEntity.getContent();
        }
        @Override
        public Header getContentEncoding() {
            return yourEntity.getContentEncoding();
        }
        @Override
        public long getContentLength() {
            return yourEntity.getContentLength();
        }
        @Override
        public Header getContentType() {
            return yourEntity.getContentType();
        }
        @Override
        public boolean isChunked() {
            return yourEntity.isChunked();
        }
        @Override
        public boolean isRepeatable() {
            return yourEntity.isRepeatable();
        }
        @Override
        public boolean isStreaming() {
            return yourEntity.isStreaming();
        } // CONSIDER put a _real_ delegator into here!

        @Override
        public void writeTo(OutputStream outstream) throws IOException {

            class ProxyOutputStream extends FilterOutputStream {
                /**
                 * @author Stephen Colebourne
                 */

                public ProxyOutputStream(OutputStream proxy) {
                    super(proxy);
                }
                public void write(int idx) throws IOException {
                    out.write(idx);
                }
                public void write(byte[] bts) throws IOException {
                    out.write(bts);
                }
                public void write(byte[] bts, int st, int end) throws IOException {
                    out.write(bts, st, end);
                }
                public void flush() throws IOException {
                    out.flush();
                }
                public void close() throws IOException {
                    out.close();
                }
            } // CONSIDER import this class (and risk more Jar File Hell)

            class ProgressiveOutputStream extends ProxyOutputStream {
                public ProgressiveOutputStream(OutputStream proxy) {
                    super(proxy);
                }
                public void write(byte[] bts, int st, int end) throws IOException {

                    // FIXME  Put your progress bar stuff here!

                    out.write(bts, st, end);
                }
            }

            yourEntity.writeTo(new ProgressiveOutputStream(outstream));
        }

    };
    ProgressiveEntity myEntity = new ProgressiveEntity();

    post.setEntity(myEntity);
    HttpResponse response = client.execute(post);

    return getContent(response);

}

public static String getContent(HttpResponse response) throws IOException {
    BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
    String body = "";
    String content = "";

    while ((body = rd.readLine()) != null)
    {
        content += body + "\n";
    }
    return content.trim();
}

我的gradle依賴

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'

compile "org.apache.httpcomponents:httpmime:4.3.6"
compile "org.apache.httpcomponents:httpclient:4.3.6"
compile "org.apache.httpcomponents:httpcore:4.2.4"

}

構建運行錯誤消息：

Answer 1

對於重復文件錯誤，請使用：

packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'
}

它不僅可以解決許多“重復文件”與apache的libs，並且可以忽略依賴性錯誤。
