Question

你好，我在上传到服务器的imageButton上显示图像时出现问题。我无法弄清楚我的错误是什么！

这是一个简短的想法，我在上传时正在做什么：位图图像 - ＆gt; Base64编码为字符串 - ＆gt;将字符串上传到服务器 - ＆gt;将字符串写入文件

下载时我正在做的一个简短的想法：从文件中读取字符串 - ＆gt;放入JSON - ＆gt;在Android中收到 - ＆gt; Base64解码到字节数组 - ＆gt;将字节数组解码为位图 - ＆gt;发布到ImageButton

java代码：

            //Storing image string
            if(scaledBitmap == null){
               bitMapPartyPicture = ((BitmapDrawable)partyPicture.getDrawable()).getBitmap();
            }else{
               bitMapPartyPicture = scaledBitmap;
            }
            String imageString = jsonParser.encodeImage(bitMapPartyPicture);

//Encoding the Image
public String encodeImage(Bitmap image){
    Bitmap bitmap = image;
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
    byte [] byte_arr = stream.toByteArray();
    Log.d("Image Base64",stream.toString());
    String image_str = Base64.encodeToString(byte_arr, Base64.DEFAULT);
    return image_str;
}

public JSONObject makeHttpRequest(String url, String method,List<NameValuePair> params) {
//Upload Image
            try{
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost("http://whatever.com/addProfilePic.php");
                httppost.setEntity(new UrlEncodedFormEntity(params));
                HttpResponse response = httpclient.execute(httppost);
                HttpEntity httpEntity = response.getEntity();
                is = httpEntity.getContent();
                is.reset();
                is.close();
            }catch(Exception e){

                  System.out.println("Error in http connection "+e.toString());
            }
        //Dealing with JSON Object
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "utf-8"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            json = sb.toString();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }

        // try parse the string to a JSON object
        try {
            Log.d("JSON Object", json);
            jObj = new JSONObject(json);
        } catch (JSONException e) {
            Log.e("JSON Parser", "Error parsing data " + e.toString());
        }

        // return JSON String
        return jObj;
}



//Download Image
public byte[] downloadImage(String url,List<NameValuePair> imgName) {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    byte[] ImageBytes = new byte[1024];
    String ImageString = null;
    byte[] DecodedImage = new byte[1024];
    try {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        httpPost.setEntity(new UrlEncodedFormEntity(imgName));
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();

        BufferedReader reader = new BufferedReader(new InputStreamReader(is, "utf-8"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        int LinesValue = 0;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
            LinesValue++;
        }

        json = sb.toString();
        Log.d("Lines",Integer.toString(LinesValue));
        Log.d("JSON Object", json);
        jObj = new JSONObject(json);
        ImageString = jObj.getString("Image_Decoded");
        ImageBytes = ImageString.getBytes(Charset.forName("UTF-8"));
        is.close();

    }
    catch(IOException t) {
        t.printStackTrace();
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    DecodedImage = Base64.decode(ImageString ,Base64.DEFAULT);

    return DecodedImage;
}

PHP上传方：

$image = $_POST['image'];// name of uploaded image
    $user  = $_POST['user'];
    $image_name = $_POST['imageName'];
    $file = null;
    $filePath = "photos/" . $user;


    $homeDir = "/home/a1400606/public_html/";
    if (!file_exists($homeDir.$filePath)) {
        mkdir($filePath, 0777);
    }
    if($image_name == 'partyPicture'){
        $file = fopen('partyPicture', 'w');
        fwrite($file, $image);
        fclose($file);

    }else if ($image_name == 'profilePicture'){
        $file = fopen('profilePicture', 'w');
        fwrite($file, $image);
        fclose($file);

    }else{
        $response["Error:"] = "Error";
    }

    if(rename(addslashes("$homeDir"."partyPicture"),addslashes( "$homeDir$filePath"."/partyPicture"))){
        $response["File Moved:"] = "Yes";
    }else {
        $response["File Moved:"] = "No";
    }

PHP下载方：

$image = "partyPicture";// name of uploaded image
    $user  = "xxxx";
    $filePath = "photos/" . $user."/";
    $homeDir = "/home/a1400606/public_html/";
    if (!file_exists(addslashes($homeDir.$filePath.$image))) {
        $response["Found File"] = "File doesn't exist";
    }else{
        $response["Found File"] = "File exist in directory";
        $imgstr=fread(fopen($homeDir.$filePath.$image,"r"),filesize($homeDir.$filePath.$image));
        $response["Image_Decoded"] = $imgstr;
    }
    echo json_encode($response);

将图像发布到ImageButton：

        byte[] bytesArray = new byte[1024];
        bytesArray = json.downloadImage(DOWNLOAD_IMAGE_URL, params);
        ImageBitmap = BitmapFactory.decodeByteArray(bytesArray, 0,bytesArray.length);
        if(ImageBitmap == null){
            InputStream is= new ByteArrayInputStream(bytesArray);
            ImageBitmap = BitmapFactory.decodeStream(is);
        }
        CreateImageBitmap = Bitmap.createBitmap(ImageBitmap);

Answer 1

我认为问题在于将数据存储在文件中。而且你也没有在服务器端提供文件扩展名，所以它创建了垃圾文件。检查它并给.jpg或.png文件名..我希望这会帮助你..

Answer 2

虽然答复很晚但可能对某人有所帮助..

您正在将图像在android中编码为base64，然后才能上传

但是在将它保存为图像之前，你无法在php端解码它。

<?php
    $image = base64_decode($_POST['image']);// decoding the uploaded image
    $user  = $_POST['user'];
    $image_name = $_POST['imageName'];
    $file = null;
    $filePath = "photos/" . $user;

希望有所帮助......

上传/下载图片问题android + PHP + Base64
