我一直在努力将数据成功地插入到MySQL数据库中（使用Volley），这不是问题，因为插入了数据，但我一直有这个错误 W / System.err：org.json.JSONException：Value＆lt;无法将java.lang.String类型的br转换为JSONObject 或JSONEception，此错误正在停止执行其他操作，如果我添加更多代码，UI冻结，我试图从我的php文件中删除日期代码并且一切都很顺利只有日期时间值不是我正在寻找的那个，当我添加回来它再次向我显示错误。这是我的代码：

    Response.Listener<String> responseListener1 = new Response.Listener<String>() {
                                                                    @Override
                                                                    public void onResponse(String response) {
                                                                        try {
                                                                            JSONObject jsonResponse1 = new JSONObject(response);
                                                                            boolean success = jsonResponse1.getBoolean("success");
                                                                            if (success) {


                                                                                Toast.makeText(MapActivity.this, "SUCCESS",Toast.LENGTH_LONG).show();


                                                                            } else {
                                                                                Toast.makeText(MapActivity.this, "INSERTION FAILED",Toast.LENGTH_LONG).show();


                                                                            }


                                                                        } catch (JSONException e) {
                                                                            e.printStackTrace();
                                                                            Toast.makeText(MapActivity.this, "EXCEPTION",Toast.LENGTH_LONG).show();
                                                                        }


                                                                    }
                                                                };




                                                                SendBookingRequest bookingRequest = new SendBookingRequest(idd,em,Adresse_source,duree,dist, responseListener1);
                                                                RequestQueue queue1 = Volley.newRequestQueue(MapActivity.this);
                                                                queue1.add(bookingRequest);

这是我的php文件 SendBookingRequest

<?php
require("password.php");
$connect = mysqli_connect("localhost", "XXXXX", "XXXXX", "XXXXX");

$driver_id = $_POST["driver_id"];
$email = $_POST["email"];
$adresse_source = $_POST["adresse_source"];
$duree = $_POST["duree"];
$distance = $_POST["distance"];
$response = array();
$dt_obj = new DateTime($response['send_moment'], new 
DateTimeZone('America/Chicago')); 
$dt_obj->setTimezone(new DateTimeZone('Europe/London')); 
$send_time = $dt_obj->format('Y-m-d H:i:s'); 
   echo $send_time;
 function AddRequest() {
    global $connect, $driver_id, $email, $adresse_source, $duree, $distance, $send_time ; 
    $statement = mysqli_prepare($connect, "INSERT INTO demande (driver_id, pass_id, adresse_source, duree, distance, send_moment) VALUES (?, (SELECT user_id FROM passager WHERE email = ?),?, ?, ?, ?)");
    mysqli_stmt_bind_param($statement, "issdis", $driver_id, $email, $adresse_source, $duree, $distance, $send_time); 
    mysqli_stmt_execute($statement);
    mysqli_stmt_close($statement);     
}


    $response["success"] = false;  

    AddRequest();
    $response["success"] = true;  


echo json_encode($response);
?>

非常感谢任何帮助。

我认为您需要将pip install PDfminer行放在from cStringIO import StringIO from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter from pdfminer.converter import TextConverter from pdfminer.layout import LAParams from pdfminer.pdfpage import PDFPage import re def convert(fname): pages=None if not pages: pagenums = set() else: pagenums = set(pages) output = StringIO() manager = PDFResourceManager() converter = TextConverter(manager, output, laparams=LAParams()) interpreter = PDFPageInterpreter(manager, converter) infile = file(fname, 'rb') for page in PDFPage.get_pages(infile, pagenums): interpreter.process_page(page) infile.close() converter.close() text = output.getvalue() output.close print text # write Content to .txt text_file = open("Output_1.txt", "w") text = re.sub("\s\s+", " ", text) text_file.write("%s" % text) text_file.close() convert("xyz.pdf")上面的PHP代码

中
