我使用 AsyncTask 将图像上传到我的虚拟主机。我将代码编写为服务。图片上传成功，但仍然存在此错误： response body is null, calling onFailure(Throwable, JSONObject)
这是安卓代码：
private void uploadToServer(Uri fileUri) {
Log.d(TAG, "onStartUpload:" + fileUri);
String str = getImageBase64(fileUri);
//http://yasirameen.com/2016/05/asynchronous-http-client-android/
RequestParams params = new RequestParams();
params.put("encoded_string",str);
params.put("image","newImage.png");
AsyncHttpClient client = new AsyncHttpClient();
//client.post(alamatServer, params, new JsonHttpResponseHandler() {
client.post("http://testkomputer.com/androidBimbel/fcm/uploadImage.php", params, new JsonHttpResponseHandler() {
ProgressDialog pd;
@Override
public void onStart() {
}
@Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
//Toast.makeText(MyUploadService.this, responseString, Toast.LENGTH_SHORT).show();
Log.d(TAG, "onFailure:" + responseString);
}
@Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
//Toast.makeText(MyUploadService.this, responseString, Toast.LENGTH_LONG).show();
String status;
try {
status = response.getString("success");
Log.d("responOnSuccess", ""+status);
if (status.equals("1")) {
Log.d("respon 1", ""+status);
// [START_EXCLUDE]
//broadcastPostFinished(1, xchatpos);

taskCompleted();
// [END_EXCLUDE]
} else if (status.equals("0")) {
// [START_EXCLUDE]
taskCompleted();
// [END_EXCLUDE]
}
} catch (JSONException e) {
e.printStackTrace();
}
//Log.d(TAG, "onSuccess:" + response.getString("success"));
}
@Override
public void onFinish() {
pd.dismiss();
}
});
}
//Converting Selected Image to Base64Encode String
private String getImageBase64(Uri selectedImage) {
Bitmap myImg = null;
try {
myImg = decodeUri(selectedImage);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
ByteArrayOutputStream stream = new ByteArrayOutputStream();
// Must compress the Image to reduce image size to make upload easy
myImg.compress(Bitmap.CompressFormat.PNG, 50, stream);
byte[] byte_arr = stream.toByteArray();
// Encode Image to String
return android.util.Base64.encodeToString(byte_arr, 0);
}
//Reducing Image Size of a selected Image
private Bitmap decodeUri(Uri selectedImage) throws FileNotFoundException {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o);
// The new size we want to scale to
final int REQUIRED_SIZE = 500;
// Find the correct scale value. It should be the power of 2.
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 2 < REQUIRED_SIZE
|| height_tmp / 2 < REQUIRED_SIZE) {
break;
}
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o2);
}
这是我的 php 代码
<?php
header('content-type : bitmap; charset=utf-8');
$respon = [
"success" => 0,
"pesan" => "post not found"];
if(isset($_POST["image"])) {
$encoded_string = $_POST["encoded_string"];
$image_name = time().$_POST["image"];
$decoded_string = base64_decode($encoded_string);
$path = 'uploads/'.$image_name;
$file = fopen($path,'w');
$is_written = fwrite($file,$decoded_string);
fclose($file);
if (file_exists($path)) {
$respon["success"] = 1;
$respon["pesan"] = "success";
}else{
$respon["success"] = 0;
$respon["pesan"] = "fail";
}
}echo json_encode($respon);?>

任何建议都会有所帮助。
通过在 JsonHttpResponseHandler 中禁用 useRFC5179Compatibility Mode 修复了类似的错误
