我无法让我的php restapi工作,它只是返回一个成功的http请求(200)的空主体。
当我只是呼出一些东西,它返回它很好。我使用的是slim(php微框架), MySQL
, apache
. 数据库表是在phpmyadmin中创建的。
索引.php
<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;
require '../vendor/autoload.php';
require '../src/config/db.php';
$app = new \Slim\App;
$app->get('/hello/{name}', function (Request $request, Response $response) {
$name = $request->getAttribute('name');
$response->getBody()->write("Hello, $name");
return $response;
});
// Customer Routes
require '../src/routes/dates.php';
$app->run();
php它还包含上面的dbhost、dbuser、dbpass和dbname变量
<?php
class db
{
// Properties
var $dbhost = 'localhost';
var $dbuser = 'root';
var $dbpass = 'parool1';
var $dbname = 'slimapp';
// Connect
public function connect()
{
$mysql_connect_str = "mysql:host=$this->dbhost;dbname=$this->dbname";
$dbConnection = new PDO($mysql_connect_str, $this->dbuser, $this->dbpass);
$dbConnection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
return $dbConnection;
}
}
日期.php
<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;
$app = new \Slim\App;
// Get All Calendar Dates
$app->get('/api/date', function (Request $request, Response $response) {
$sql = "SELECT * FROM `calendardates`";
try {
// Get DB Object
$db = new db();
// Connect
$db = $db->connect();
$stmt = $db->query($sql);
$dates = $stmt->fetchAll(PDO::FETCH_OBJ);
$db = null;
echo json_encode($dates);
} catch (PDOException $e) {
echo '{"error": {"text": ' . $e->getMessage() . '}';
}
});
解决方案:
将数据库表的排序规则更改为utf8(如果您想使用诸如ö, ä, ü" 在数据库表中)。
我变了
$dbConnection = new PDO($mysql_connect_str, $this->dbuser, $this->dbpass);
至
$dbConnection = new PDO($mysql_connect_str, $this->dbuser, $this->dbpass, array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
来解决问题。
