【问题描述】:
我一直在做一个关于使用 php 将 android 连接到 mysql 的教程,我一直收到这个错误消息
error parsing data org.json.JOSNException:VALUE<HTML><TITLE>404
type java.lang.String cannot be converted to JSON object
据我所知,php文件中有问题,有人可以告诉我如何解决它
<?php
/*
* Following code will create a new product row
* All product details are read from HTTP Post Request
*/
// array for JSON response
$response = array();
// check for required fields
if (isset($_POST['name']) && isset($_POST['price']) && isset($_POST['description'])) {
$name = $_POST['name'];
$price = $_POST['price'];
$description = $_POST['description'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// mysql inserting a new row
$result = mysql_query("INSERT INTO products(name, price, description) VALUES('$name', '$price', '$description')");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Product successfully created.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
?>
【问题讨论】:
-
看起来您从中获取 JSON 结果的 URL 是错误的。
-
在 JSON 编码之前,您也可能在输出中收到错误。如果您检查原始响应 - 它是否仅包含 JSON?
