android 文件上传，中文utf-8编码

要上传文件到后台的php服务器,服务器能收到中文,手机发送过去,却只能收到一堆转了UTF-8的编码(就是要decode后才是中文的编码).android这边上传文件通常是用stream方式上传的,用MultipartEntity这个开源包来上传了会有编码问题.

首先设置字段的编码

//CustomMultiPartEntity entity=new CustomMultiPartEntity(HttpMultipartMode.BROWSER_COMPATIBLE,null,Charset.forName("UTF-8"),listener);
//不需要构造函数，只要对应的文字是utf-8编码，传输是utf-8编码就可以
CustomMultiPartEntity multipartContent = new CustomMultiPartEntity(listener);
entity.addPart(title, new StringBody(message,Charset.forName("UTF-8")));
entity.addPart(fileName,new FileBody(uploadFile));
listener.total(uploadFile.length());

http传输的编码

public static String getUploadRequest(String url,MultipartEntity entity){
        String result=null;
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(url);
        try {            
            HttpParams params = httpclient.getParams();
            params.setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET, Charset.forName("UTF-8"));/API 识别 charset
            HttpConnectionParams.setConnectionTimeout(params, 10*1000); //连接超时
            HttpConnectionParams.setSoTimeout(params, 10*1000);             //读取数据超时
            httppost.setEntity(entity);
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity resEntity = response.getEntity();
            if(response.getStatusLine().getStatusCode()==HttpStatus.SC_OK){
                result = EntityUtils.toString( resEntity, HTTP.UTF_8);
                Log.e(TAG, "result:"+result);
                return result;
            }
            if(resEntity!=null){
                resEntity.consumeContent();
            }
            httpclient.getConnectionManager().shutdown();
            return result;          
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
        return null;
    }
