Javascript 无法从angularJS中的mysql提取数据

我在angularJS很新。我已经向mysql的所有客户展示了使用。因此，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;
    });
});

我用php编写了：

$result = mysqli_query($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

，因为当我直接将这个数组写入变量

customers

时，它就工作了。i、 e

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"}]

但是我不能动态地将它放在get方法result成功之后。

从您的服务返回

$http

承诺，然后在.success回调中设置$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");
    };
});

如果我这样使用

$http.get（“app/server/read.php”）.success（函数（数据）{var customers=data；}）；}），我发现有一个错误就是，客户没有定义。请告诉我如何定义客户，因为如果我按照你的方式，其他操作会受到影响。var客户定义客户，但你不想使用var，你想像我在回答中所做的那样将其添加到范围中。是的，我理解，但是，是否可以从mysql中提取数据并将其放入变量中，然后将其添加到范围中？是的
var something=data$scope.customers=something
