Question

我是angularJS的新手。我一直在使用mysql显示所有客户。所以，我在cotroller和service中写道：

app.controller('CustomersController', function ($scope, customersService, $http) {

init();

function init() {
    $scope.customers = customersService.getCustomers();
}

});

app.service('customersService', function ($http) {
this.getCustomers = function () {
    return customers;
};
// my issue is here
$http.get("app/server/read.php")
    .success(function(data){
        var customers = data;
    });
});

在php中我写道：

$result = mysqli_query($con,"SELECT * FROM customers");
$return_arr = array();
while($row = $result->fetch_array(MYSQLI_ASSOC))
{
$rowArr = array(
    'id' => $row['id'],
    'firstName' => $row['firstname'],
    'lastName' => $row['lastname'],
    'address' => $row['address'],
    'city' => $row['city']
);

$return_arr[] = $rowArr;
}
echo json_encode($return_arr);

php将json数组返回为：

[{"id":"36","firstName":"asdasd","lastName":"asdasd","address":"","city":"asdasd"},{"id":"37","firstName":"asdasd","lastName":"asdasd","address":"","city":"asdasd"},{"id":"38","firstName":"asdasd","lastName":"asdasd","address":"","city":"asdasd"},{"id":"39","firstName":"","lastName":"","address":"","city":""},{"id":"40","firstName":"asd","lastName":"asd","address":"","city":"asd"}]

我不明白如何将这个json对象数组放入变量customers，因为当我将这个数组直接写入变量customers时，它就可以了。即。

var customers = [{"id":"36","firstName":"asdasd","lastName":"asdasd","address":"","city":"asdasd"},{"id":"37","firstName":"asdasd","lastName":"asdasd","address":"","city":"asdasd"},{"id":"38","firstName":"asdasd","lastName":"asdasd","address":"","city":"asdasd"},{"id":"39","firstName":"","lastName":"","address":"","city":""},{"id":"40","firstName":"asd","lastName":"asd","address":"","city":"asd"}]

但是，在获得get方法结果成功后，我无法动态地设置它。

从您的服务返回$http承诺，然后在.success回调中设置您的$ scope属性。

app.controller('CustomersController', function ($scope, customersService, $http) {

    init();

function init() {
    customersService.getCustomers().success(function(data){
        $scope.customers = data;
    });
}

});

app.service('customersService', function ($http) {
    this.getCustomers = function () {
        return $http.get("app/server/read.php");
    };
});

无法从angularJS中的mysql中提取数据
