Question

在我的应用程序中，我必须从图库中选择一个图像并将其设置为个人资料图片。为此，我已将图像编码为字符串并将其发送到服务器。从服务器接收响应时，它显示以下错误

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<html><head>
<title>414 Request-URI Too Long</title>
</head><body>
<h1>Request-URI Too Long</h1>
<p>The requested URL's length exceeds the capacity limit for this server.<br /></p><hr>
<address>Apache/2.4.3 (Win32) OpenSSL/1.0.1c PHP/5.4.7 Server at localhost Port80</address></body></html>

要将图像转换为字符串，我使用了以下代码：

profileimage.buildDrawingCache();
            Bitmap bm = profileimage.getDrawingCache();
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bm.compress(Bitmap.CompressFormat.JPEG, 100, baos);

            byte[] b = baos.toByteArray();
            String encodedImage = null;
            encodedImage = Base64.encodeToString(b, Base64.NO_WRAP);

请帮我修复错误。

上传图片的代码：

public class PickGalleryImageActivity extends Activity implements
        OnClickListener {

    private static int RESULT_LOAD_IMAGE = 1;

    private ImageView profileimage = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


        profileimage .setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {


        if (v.getId() == R.id.imageView) {

        Intent i = new Intent(Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

        startActivityForResult(i, RESULT_LOAD_IMAGE);
        }



    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

             profileimage  = (ImageView) findViewById(R.id.imageView);
             profileimage .setImageBitmap(BitmapFactory.decodeFile(picturePath));

        }

}

服务器呼叫代码：

public class ServerCommunication {
    String msg;
    String url;
    static DefaultHttpClient httpclient = new DefaultHttpClient();

    public String makeServiceCall(String url, final Context context) {
        this.url = url;

        try {

            if (!isConnected(context)) {

                return url;
            }
            if (isConnected(context) == false) {
                Toast.makeText(context, "No Connection Available", 500).show();
            }


            URI uri = new URI(url.replace(" ", "%20"));
            Log.d("uri", url + "");

            HttpPost httppost = new HttpPost(uri);


            HttpParams httpParameters = httppost.getParams();

            int timeoutConnection = 100000;
            HttpConnectionParams.setConnectionTimeout(httpParameters,
                    timeoutConnection);

            int timeoutSocket = 100000;
            HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

            HttpResponse response = httpclient.execute(httppost);

            List<Cookie> cookies = httpclient.getCookieStore().getCookies();
            if (cookies.isEmpty()) {
                System.out.println("None");
            } else {
                for (int i = 0; i < cookies.size(); i++) {
                    System.out.println("- " + cookies.get(i).toString());
                }
            }
            int responseCode = response.getStatusLine().getStatusCode();
            /* Checking response */
            if (response != null) {
                msg = EntityUtils.toString(response.getEntity());

            }
            Log.d("serverResponse", msg);
            // Toast.makeText(getApplicationContext(), msg, 500).show();

        } catch (Exception e) {
            e.printStackTrace();
        }
        return msg;

    }

    public static boolean isConnected(Context context) {
        ConnectivityManager connMgr = (ConnectivityManager) context
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
        if (networkInfo != null && networkInfo.isConnected()) {
            return true;
        } else {

            return false;
        }
    }
}

Answer 1

HttpClient httpclient = new DefaultHttpClient();
try{
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("image", imageString));
nameValuePairs.add(new BasicNameValuePair("Country", "country name"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
httpclient.execute(httppost);
}catch (ClientProtocolException e) {
 // TODO Auto-generated catch block
}

使用Post方法将数据发送到服务器，当您将位图转换为ImageString时，该字符串对于URL为long。所以使用POST方法来请求服务器，这将起作用。

就像那样：它将Post请求作为josn发送，您可以使用自己的字符串实体

public static String callWebService(String value, String urlString) {
            String responseString = "";
    try {
        // make web service connection
        HttpPost request = new HttpPost(urlString);
        request.setHeader("Accept", "application/json");
        request.setHeader("Content-type", "application/json");
        // Build JSON string
        JSONStringer TestApp = new JSONStringer().object().key("imageString").value(value);
        StringEntity entity = new StringEntity(TestApp.toString());

        Log.d("****Parameter Input****", "Testing:" + TestApp);
        request.setEntity(entity);
        // Send request to WCF service
        DefaultHttpClient httpClient = new DefaultHttpClient();
        responseString = convertStreamToString(response.getEntity().getContent());  

    } catch (Exception e) {
        e.printStackTrace();
        responseString = e.getMessage();
    }

    return responseString;
}

如何从服务器发送和接收编码的字符串图像？
