不使用multipart httppost方法在android中发布图像文件-Java 学习之路

这个问题是从same question借来的，因为我面临同样的问题 . 在服务器端发布图像时，图像细节无法进入服务器端 . 像这样：

无法发布图像文件信息php服务器，userid ok但图像文件信息无法发布 . 在这种情况下，Image在服务器上成功保存，我无法获取有关图像的php服务器的信息 .

这是代码：

公共类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);

    }
}

我喜欢这个：

Array
(
    [UserId] => 1
)

我在php中使用它进行测试，来自multipart：

$ 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，多部分post方法中是否有任何遗漏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
        )

我也遵循这个教程：[http://www.webspeaks.in/2012/08/upload-files-from-android-to-server.html][2]

[2]：http://www.webspeaks.in/2012/08/upload-files-from-android-to-server.html和 googled 中的很多其他，但找不到合适的解决方案 .

我最近做的就像你的问题这是解决方案：

来自SD卡和相机的图像：

@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，您调用要上传图片的函数：

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);

这是上传图片类别：

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感到满意 . 我成功运行了 .
