在我的本地服务器中注册其他用户时，我收到以下错误：

这是我在php中与所有内容相关的代码的另一部分：
} else if ($tag == 'register') {
// Request type is Register new user
$response ["success"] = 1;
$response ["uid"] = $user ["unique_id"];
$response ["user"] ["name"] = $user ["name"];
$response ["user"] ["username"] = $user ["username"];
$response ["user"] ["email"] = $user ["email"];
$response ["user"] ["zipcode"] = $user ["zipcode"];
$response ["user"] ["password"] = $user ["password"];
$response ["user"] ["created_at"] = $user ["created_at"];
$response ["user"] ["updated_at"] = $user ["updated_at"];
$response ["user"] ["skills"] = $user ["skills"];
// check if user is already existed
if ($db->isUserExisted ( $email )) {
// user is already existed - error response
$response ["error"] = 2;
$response ["error_msg"] = "User already existed";
echo json_encode ( $response );
} else if (! $db->validEmail ( $email )) {
$response ["error"] = 3;
$response ["error_msg"] = "Invalid Email Id";
echo json_encode ( $response );
} else {
// store user
$user = $db->storeUser ( $name, $email, $password, $unique_id, $dateofbirth, $zipcode, $skills, $username, $updated_at, $created_at );
if ($user) {
// user stored successfully
$response ["uid"] = $user ["unique_id"];
$response ["user"] ["name"] = $user ["name"];
$response ["user"] ["username"] = $user ["username"];
$response ["user"] ["email"] = $user ["email"];
$response ["user"] ["zipcode"] = $user ["zipcode"];
$response ["user"] ["password"] = $user ["password"];
$response ["user"] ["created_at"] = $user ["created_at"];
$response ["user"] ["updated_at"] = $user ["updated_at"];
$response ["user"] ["skills"] = $user ["skills"];
$response ["user"] ["uid"] = $user ["unique_id"];
mail ( $email, $subject, $message, $headers );
echo json_encode ( $response );
} else {
// user failed to store
$response ["error"] = 1;
$response ["error_msg"] = "JSON Error occured in Registartion";
echo json_encode ( $response );
}
}
}
最后，这是我的数据功能之一：
public function storeUser($name, $email, $username, $password, $zipcode, $skills) {
$uuid = uniqid('', true);
$hash = $this->hashSSHA($password);
$encrypted_password = $hash["encrypted"]; // encrypted password
$salt = $hash["salt"]; // salt
$result = mysql_query("INSERT INTO users(unique_id, name, email, username,
encrypted_password, salt, created_at) VALUES('$uuid', '$name', '$email', '
$username','$zipcode', '$skills' '$encrypted_password', '$salt', NOW())");
// check for successful store
if ($result) {
// get user details
$uid = mysql_insert_id(); // last inserted id
$result = mysql_query("SELECT * FROM users WHERE uid = $uid");
// return user details
return mysql_fetch_array($result);
} else {
return false;
}
}
我很抱歉这篇文章中列出的所有代码。我不知道错误有多深，但我确实知道它在这些代码行之间。
String res = json.getString("success");
System.out.println(91);
System.out.println(res);
if (Integer.parseInt(res) == 1) { //Line 134 of regular user creation as said in
log cat
请以任何可能的方式帮助我。
答案 0 :(得分：0)
这意味着成功密钥不存在。
每次设置错误时，都应将成功设置为false：
$response ["success"] = 0;
JSON支持您应该使用它的布尔值（true或false），它将使解析更容易。
Boolean res = json.getBoolean("success");
if(res){
//success
}
您不必映射用户的每个属性，您可以通过直接存储用户对象来构建多维数组。
此外，您应该只在最后一次回显JSON，如果满足多个条件，这将避免无效的json。
您将拥有以下内容：
$response = array();
...
}else if ($tag == 'register') {
// check if user is already existed
if ($db->isUserExisted ( $email )) {
$response ["success"] = false;
$response ["error_msg"] = "User already existed";
echo json_encode ( $response );
} else if (! $db->validEmail ( $email )) {
$response ["success"] = false;
$response ["error_msg"] = "Invalid Email Id";
echo json_encode ( $response );
} else {
// store user
$user = $db->storeUser ( $name, $email, $password, $unique_id, $dateofbirth, $zipcode, $skills, $username, $updated_at, $created_at );
if ($user) {
// user stored successfully
// Request type is Register new user
$response ["success"] = true;
$response ["user_data"] = $user;
mail ( $email, $subject, $message, $headers );
echo json_encode ( $response );
} else {
$response ["success"] = false;
$response ["error_msg"] = "JSON Error occured in Registartion";
}
}
}
echo json_encode ( $response );
