所以我试图将emojis存储在我的数据库中并在我的应用程序中返回它们。我用离子v1制作了一个小型的消息,一切正常。我只想正确存储表情符号并在应用程序中显示它们。我的整个数据库,表和列都设置为utf8mb4所以我知道这很好。当我将$http
发送到我的php
时,它也看起来很棒:{"from_account_id":"xxxx","for_account_id":"xxxx","message":""}:
但是当我在php
中打印它时,它看起来像这样:{"from_account_id":"106191","for_account_id":"989014","message":"đ˝"}
并且在我的mysql到处都放了一个表情符号?
。我还能做什么?我还将我的php中的标题设置为UTF_8
。我知道有很多问题,但我已经跟随了他们中的大多数,但仍然没有解决我的问题。
我在php中存储消息:
<?php
header('Content-Type: text/html; charset=utf-8');
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
include_once 'config.php';
$data = file_get_contents("php://input");
$data = json_decode($data, true);
try {
$stmt = $dbh->prepare("INSERT INTO `messages` (`message_id`, `from_account_id`, `for_account_id`, `date_read`, `message`)
VALUES (NULL, :from_account_id, :for_account_id, NULL, :message)");
$stmt->bindValue(':from_account_id', $data['from_account_id']);
$stmt->bindValue(':for_account_id', $data['for_account_id']);
$stmt->bindValue(':message', $data['message']);
$stmt->execute();
} catch (PDOException $e) {
throw $e;
}
echo 'Success';
?>
我发送邮件的AngularJS
函数:
$scope.sendMessage = function(for_account_id, message){
if(for_account_id != null && message != null){
$http({
method: 'post',
url: 'myurl',
data: {
from_account_id: $rootScope.unique_id,
for_account_id: for_account_id,
message: message,
},
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).then(function successCallback(data){
$scope.thisMessage = null;
$scope.getMessages();
$rootScope.webSocket.send($stateParams.chatId + "|" + $rootScope.unique_id + "|" + 'newMessage');
$scope.markAsRead();
})
}
}
这是我与数据库的连接:
<?php
$hostname='myhost';
$username='myuser';
$password='mypassword';
$options = array(PDO::MYSQL_ATTR_INIT_COMMAND=>'SET NAMES utf8');
try {
$dbh = new PDO("mysql:host=$hostname;dbname=mydbname;charset=utf8mb4",$username,$password, $options);
$dbh->query ('SET NAMES utf8');
$dbh->query ('SET CHARACTER_SET utf8_unicode_ci');
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
echo $e->getMessage();
}
?>
我想念的任何提示或想法?
答案 0 :(得分:0)
Okey所以我已经解决了我的问题。我这样做的方式不是最好的,但它有效。所以基本上在数据库中存储unicodes就像那样简单:
我将我要插入数据的文件中的header
更改为:
header('Content-Type: application/json; charset=utf-8');
我再次将消息编码为json,同时插入它:
$stmt->bindValue(':message', json_encode($data['message']));
在再次回复我的应用之前,将标题设置为:
header('Content-Type: application/json; charset=utf-8');
我的代码现在看起来像这样:
<?php
header('Content-Type: application/json; charset=utf-8');
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
include_once 'config.php';
$data = file_get_contents("php://input");
$data = json_decode($data, true);
try {
$stmt = $dbh->prepare("INSERT INTO `messages` (`message_id`, `from_account_id`, `for_account_id`, `date_read`, `message`)
VALUES (NULL, :from_account_id, :for_account_id, NULL, :message)");
$stmt->bindValue(':from_account_id', $data['from_account_id']);
$stmt->bindValue(':for_account_id', $data['for_account_id']);
$stmt->bindValue(':message', json_encode($data['message']));
$stmt->execute();
} catch (PDOException $e) {
header('Content-Type: text/html; charset=utf-8');
throw $e;
}
header('Content-Type: text/html; charset=utf-8');
echo 'Success';
?>
所以这个问题已修复,unicodes存储在我的数据库中。
然后我又在一个尴尬的情况下再次进行游戏,因为在从mysql
获取数据并将其编码到json
时发送到我的应用,我的应用无法将unicodes返回给特殊字符甚至我用ng-bind-html
绑定它并使用$sce.trustAsHtml()
。通常情况下,我只是将查询结果发送为encoded json
,但它并没有像我说的那样工作。所以我所做的就是这样:
<?php
header('Content-Type: application/json; charset=utf-8');
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
include_once 'config.php';
$data = file_get_contents("php://input");
$data = json_decode($data, true);
try {
$stmt = $dbh->prepare("SELECT * from messages WHERE (from_account_id = :unique_id AND for_account_id = :user_2) OR (from_account_id = :user_2 AND for_account_id = :unique_id)");
$stmt->bindValue(':unique_id', $data['user_1']);
$stmt->bindValue(':user_2', $data['user_2']);
$stmt->execute();
} catch (PDOException $e) {
throw $e;
}
$rows = $stmt->rowCount();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
if ($rows > 0){
$i = 0;
echo "[";
foreach ($result as $key => $value){
$i++;
echo "{";
echo '"message_id"' . ":" . '"' .$value['message_id']. '"' .", ";
echo '"from_account_id"' . ":" . '"' .$value['from_account_id']. '"' .", ";
echo '"for_account_id"' . ":". '"' .$value['for_account_id']. '"' .", ";
echo '"date_sent"' . ":" . '"' .$value['date_sent']. '"' .", ";
echo '"date_read"' . ":" . '"' .$value['date_read']. '"' .", ";
echo '"message"' . ":" . '"' .str_replace("\n", "</br>", json_decode($value['message'])). '"' ;
echo "}";
if($i != $rows){
echo ",";
}
if($i == $rows){
echo "]";
}
echo "\n";
}
exit;
}
else {
echo 'Something went wrong';
exit;
}
?>
将解码后的json
发送到我的angularjs作为我自己制作的真实json的字符串中解决。
我已经在这个问题上添加了anwser,因为也许有人会遇到同样的麻烦,这会有所帮助。
