我将表单发送到服务器，文本来自字段和文件Edittext。我想我会发出错误的形状。这是发送浏览器的一种形式：

我使用AsyncTask帮助上传文件。

 private String uploadFile() {
        String responseString = null;

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(UPLOAD_URL);
        MultipartEntity entity = new MultipartEntity(
                HttpMultipartMode.BROWSER_COMPATIBLE);

        try {


            File filePathstorage = new File(getPath(filePath));//путь к файлу

            filename = filePathstorage.getName();//имя файла

            File path = Environment.getExternalStoragePublicDirectory(
                    Environment.DIRECTORY_PICTURES);

            //File sendingFile = new File(path, filename);

            FileBody body = new FileBody(filePathstorage, "Content-Type: image/jpeg", filename);

            entity.addPart(KEY_NAME, new StringBody(name));
            entity.addPart(KEY_NASELPUNKT, new StringBody(naselpunkt));
            entity.addPart(KEY_STREET, new StringBody(street));
            entity.addPart(KEY_DOM, new StringBody(house));
            entity.addPart(KEY_EMAIL, new StringBody(e_mail));
            entity.addPart(KEY_MESAGES, new StringBody(message));


            entity.addPart(KEY_IMAGE, body);//  public static final String KEY_IMAGE = "fileFF[]";


            Log.e("RESULT_OTVET_entity", "Response from server: " + entity);
            httppost.setEntity(entity);

            HttpResponse response = httpclient.execute(httppost);
            HttpEntity r_entity = response.getEntity();

            BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
            String sResponse;
            StringBuilder s = new StringBuilder();
            while ((sResponse = reader.readLine()) != null) {
                s = s.append(sResponse);
            }
            Log.v("Response for POst", s.toString());


            int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode == 200) {
                // Server response
                responseString = EntityUtils.toString(r_entity);
            } else {
                URLDecoder.decode(URLEncoder.encode(responseString, "iso8859-1"), "UTF-8");
                responseString = "Error occurred! Http Status Code: " + statusCode;
            }

        } catch (IOException e) {
            responseString = e.toString();
        }

        return responseString;

    }

在日志中我看到错误：

Caused by: java.nio.charset.UnsupportedCharsetException: IMG_20161115_113532.jpg

此行中的错误

 FileBody body = new FileBody(filePathstorage, "Content-Type: image/jpeg", filename);

Answer 1

尝试更改FileBody构造函数中的参数：GET https://i.pximg.net/img-original/img/2014/02/09/00/10/03/41485846_p0.jpg HTTP/1.1 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36 Accept: image/webp,image/*,*/*;q=0.8 Referer: http://www.pixiv.net/whitecube/user/2824699/illust/41485846 Accept-Encoding: gzip, deflate, sdch, br Accept-Language: en-US,en;q=0.8,sl;q=0.6 Host: i.pximg.net

请参阅：https://hc.apache.org/httpcomponents-client-ga/httpmime/apidocs/org/apache/http/entity/mime/content/FileBody.html#constructor_summary

Answer 2

中似乎filename

FileBody body = new FileBody(filePathstorage, "Content-Type: image/jpeg", filename);

行解释为charset。这是因为您可能使用旧版本的Apache HttpClient Mime API。

所以尝试类似的东西：

FileBody bin = new FileBody(new File(filename));

错误：使用MultipartEntity实体上载文件时出现UnsupportedCharsetException
