post服務器會有記錄嗎，android post數據到php服務器,通過post方法將數據上傳到服務器Android Studio

我正試圖通過android studio中的POST請求上傳一張圖片到服務器上，但我完全被困住了。 控制臺沒有給我任何信息，可以指出出了什么問題，當我單擊上傳，它只是不工作。 我在postexecute中調用的toast甚至沒有顯示出來，但是在toast之后我放進去的print顯示出來了，所以程序在執行時肯定會顯示出來。

代碼如下:public class UploadActivity extends AppCompatActivity implements View.OnClickListener {

post服務器會有記錄嗎？ImageView imageToUpload;

Button uploadButton;

EditText imageNameText;

服務器接收不到post請求。ImageButton backButton;

private static final int RESULT_LOAD_IMAGE=1;

private static final String SERVER_ADDESS = "http://lukertestsite.000webhostapp.com/"; // address of my free 000webhost domain

php get post。@Override

protected void onCreate(@Nullable Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.upload_page);

imageToUpload = (ImageView)findViewById(R.id.imageToUpload);

uploadButton = (Button)findViewById(R.id.uploadImageButton);

imageNameText = (EditText)findViewById(R.id.imageName);

backButton = (ImageButton)findViewById(R.id.returnButton);

// set a listener for each button that will pass this as the view, since this class implements listener

imageToUpload.setOnClickListener(this);

uploadButton.setOnClickListener(this);

backButton.setOnClickListener(this);

}

@Override

public void onClick(View view) {

switch(view.getId()){

case R.id.imageToUpload:

Intent localImagesIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

startActivityForResult(localImagesIntent, RESULT_LOAD_IMAGE);

break;

case R.id.uploadImageButton:

Bitmap pic = ((BitmapDrawable) imageToUpload.getDrawable()).getBitmap(); // grab the pic as a bitmap

new UploadImage(pic,imageNameText.getText().toString()).execute();

break;

case R.id.returnButton:

break;

}

}

@Override

protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {

super.onActivityResult(requestCode, resultCode, data);

if(requestCode == RESULT_LOAD_IMAGE && resultCode==RESULT_OK && data!=null) { // ensuring the gallery intent is what calls the method, and the result is ok and data is passed i.e. not null

Uri selectedImage = data.getData(); // making a uniform result (basically a pointer to the image)

imageToUpload.setImageURI(selectedImage); // set the image to upload display to the selected image.

}

}

// asynch task to commiunicate with server in the background

private class UploadImage extends AsyncTask{

Bitmap image;

String name;

public UploadImage(Bitmap image, String name){

this.image=image;

this.name=name;

}

@Override

protected Void doInBackground(Void... voids) {

// encode image in base 64

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

image.compress(Bitmap.CompressFormat.PNG,100,byteArrayOutputStream); // compress as a png into bytearraystream

String encodedImage = Base64.encodeToString(byteArrayOutputStream.toByteArray(),Base64.DEFAULT);

ArrayList dataToSend = new ArrayList<>();

dataToSend.add(new BasicNameValuePair("image",encodedImage));

dataToSend.add(new BasicNameValuePair("name",name));

HttpParams httpRequestParams = getHttpRequestParams();

HttpClient client = new DefaultHttpClient(httpRequestParams);

HttpPost post = new HttpPost(SERVER_ADDESS + "UploadPic.php");

try{

post.setEntity(new UrlEncodedFormEntity(dataToSend));

System.out.println("set post entity");

client.execute(post);

System.out.println("executing post");

}catch (Exception e){

e.printStackTrace();

}

return null;

}

@Override

protected void onPostExecute(Void aVoid) {

super.onPostExecute(aVoid);

Toast.makeText(getApplicationContext(),"Your pic was uploaded",Toast.LENGTH_SHORT); //Toast to alert user their file was uploaded

System.out.println("toasted");

}

}

private HttpParams getHttpRequestParams(){

System.out.println("getting request params");

HttpParams httpRequestParams = new BasicHttpParams();

HttpConnectionParams.setConnectionTimeout(httpRequestParams,1000*40);

HttpConnectionParams.setSoTimeout(httpRequestParams,1000*40);

return httpRequestParams;

}

下面是代碼中使用的PHP文件:<?php

$image = $_POST["image"];

$decodedImage = base64_decode("$image");

file_put_contents("picbox_pics/" . $name . ".PNG", $decodedImage);

如果你有任何想法，我會非常感激的，因為我已經被困了一天左右了。 我認為這可能與“d/compatibilitychangeReporter:Compat change id reported:147798919；UID 10152；state:enabled”有關，它恰好發生在吐司應該發生的時候(或者至少在我的“吐司”打印之前的一段時間)，但是我不能在模擬器中關閉該選項，我甚至不確定這是問題所在。
