java - 当我尝试使用 Volley 将图像从 Android 上传到 PHP 服务器时出现错误(JSONException)

Question

当我将图像从 Android 设备上传到 PHP Web 服务器时，出现无法修复的错误。更准确地说，我得到错误:

org.json.JSONException: Value <br of type java.lang.String cannot be converted to JSONObject

老实说我不明白为什么。我附上了下面的 PHP 脚本，希望您能够找出错误。

<?php
// Path to move uploaded files
$target_path = dirname(__FILE__).'.';

if (isset($_FILES['image']['name'])) {
    $target_path = $target_path . basename($_FILES['image']['name']);

    try {
        // Throws exception incase file is not being moved
        if (!move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {
            // make error flag true
            echo json_encode(array('status'=>'fail', 'message'=>'could not move file'));
        }

        // File successfully uploaded
        echo json_encode(array('status'=>'success', 'message'=>'File Uploaded'));
    } catch (Exception $e) {
        // Exception occurred. Make error flag true
        echo json_encode(array('status'=>'fail', 'message'=>$e->getMessage()));
    }
} else {
    // File parameter is missing
    echo json_encode(array('status'=>'fail', 'message'=>'Not received any file'));
}
?>

而图片上传函数是这样定义的

private void imageUpload(final String imagePath) {

SimpleMultiPartRequest smr = new SimpleMultiPartRequest(Request.Method.POST, BASE_URL,
        new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                Log.d("Response", response);
                try {
                    JSONObject jObj = new JSONObject(response);
                    String message = jObj.getString("message");

                    Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();

                } catch (JSONException e) {
                    // JSON error
                    e.printStackTrace();
                    Toast.makeText(getApplicationContext(), "Json error: " + e.getMessage(), Toast.LENGTH_LONG).show();
                }
            }
        }, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
    }
});

smr.addFile("image", imagePath);
MyApplication.getInstance().addToRequestQueue(smr);

您认为我为什么会收到此错误？
