android - 不使用多部分httppost方法在android中发布图像文件

Question

本题借自same question ，因为我遇到了同样的问题。在服务器端发布图片时，图片细节无法进入服务器端。像这样:

上传图片文件信息php服务器失败，userid ok但是图片文件信息无法上传。在这种情况下，图片成功保存在服务器上，我无法获取图片的php服务器信息。

代码如下:

公共(public)类 UploadImageHttpPost {

String testpath="/mnt/sdcard/14111.jpg";
String url = "http://andtuts.com/uploadImage.php";

public static void sendPost(String url, String imagePath,String userId)
        throws IOException, ClientProtocolException {
     String responseBody;

    MultipartEntity entity = new MultipartEntity(
            HttpMultipartMode.BROWSER_COMPATIBLE);

    File file = new File(imagePath);
    FileBody encFile = new FileBody(file,"image/jpeg");
    entity.addPart("images", encFile);
    entity.addPart("UserId", new StringBody(userId));
    HttpPost request = new HttpPost(url);
    request.setEntity(entity);

    HttpClient client = new DefaultHttpClient();

    ResponseHandler<String> responsehandler = new BasicResponseHandler();
    responseBody = client.execute(request, responsehandler);

    if (responseBody != null && responseBody.length() > 0) {
        Log.w("TAG", "Response from image upload->" + responseBody);

    }
}

我是这样的:

Array
(
    [UserId] => 1
)

我在 php 中使用它进行测试的地方，来自 multipart 的内容:

$filedata = $_FILES['images'];
$f = fopen(time().".txt",'wb');
fwrite($f, print_r($_REQUEST,true));
fclose($f);

但是下面的部分缺失意味着我没有得到，multipart post 方法中是否有任何缺失的代码请检查上面的 java 代码:

[images] => Array
        (
            [name] => ball.png
            [type] => image/png
            [tmp_name] => /tmp/phpiQHIXQ
            [error] => 0
            [size] => 1664972
        )

我也在学习这个教程:[ http://www.webspeaks.in/2012/08/upload-files-from-android-to-server.html][2]

我最近在做你的问题这是解决方案:

从 SD 卡和相机拍摄的图像:

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        Bitmap scaledphoto = null;
        int height = 100;
        int width = 100;
        if (resultCode == RESULT_OK) {
            if (requestCode == SD_REQUEST) {
                Uri selectedImageUri = data.getData();
                selectedImagePath = getPath(selectedImageUri);
                yourSelectedImage = BitmapFactory.decodeFile(selectedImagePath);
                scaledphoto = Bitmap.createScaledBitmap(yourSelectedImage,
                        height, width, true);
                pImage.setImageBitmap(scaledphoto);

                Uri selectedImageUri1 = data.getData();
                path = getRealPathFromURI(selectedImageUri1);


            }
            if (requestCode == CAMERA_REQUEST) {
                yourSelectedImage = (Bitmap) data.getExtras().get("data");
                scaledphoto = Bitmap.createScaledBitmap(yourSelectedImage,
                        height, width, true);
                profImage.setImageBitmap(scaledphoto);
                Uri selectedImageUri1 = data.getData();
                path = getRealPathFromURI(selectedImageUri1);

            }
        }

现在调用Function，要上传图片的地方:

    String url="http://test.com/uploadimage.php";
    //path is the defined, which is take from camera and sdcard.
   // userid is, which user do you want upload picture.
    UploadImageHttp.sendPost(url, path, userId);

这是上传图片的类:

public class UploadImageHttp {
public static void sendPost(String url, String imagePath,String userId)
        throws IOException, ClientProtocolException {

    String responseBody;
    HttpClient client = new DefaultHttpClient();
    HttpPost request = new HttpPost(url);

    MultipartEntity entity = new MultipartEntity(
            HttpMultipartMode.BROWSER_COMPATIBLE);

    File file = new File(imagePath);
    ContentBody encFile = new FileBody(file,"image/png");

    entity.addPart("images", encFile);
    entity.addPart("UserId", new StringBody(userId));

    request.setEntity(entity);



    ResponseHandler<String> responsehandler = new BasicResponseHandler();
    responseBody = client.execute(request, responsehandler);


    if (responseBody != null && responseBody.length() > 0) {
        Log.w("TAG", "Response image upload" + responseBody);

    }
}

我希望你对这段代码满意。我运行成功。
