我对 Angular.JS 开发相当陌生,但过去有使用 PHP、HTML 和 JS 的经验,因此我目前正在构建一个以 Angular.JS 作为前端、PHP Slim 作为 API 后端的 Web 应用程序。我已经成功地使用 Angular.JS $http.post 为我的一个调用实现了基于 token 的身份验证,但似乎无法在另一个不需要 token 身份验证的 $http.post 请求中获得所需的结果。
请求 1 - Angular.JS(正在运行):
function ($scope, $http, $location) {
console.log("REACHED");
$scope.master = {};
$scope.activePath = null;
$scope.New_Customer = function(customer, AddNewForm) {
console.log(customer);
console.log("2: " + JSON.stringify(customer));
console.log("SCOPE: " + customer.status);
$http({
method: "post",
url: "v1/customers",
headers: {
'authorization': token,
'Content-Type': 'application/x-www-form-urlencoded'
},
data: $.param({first_name: customer.first_name, last_name: customer.last_name, email: customer.email, mobile_number: customer.mobile_number, home_number: customer.home_number, address_line1: customer.address_line1, address_line2: customer.address_line2, city: customer.city, postalcode: customer.postalcode, 'status': customer.status})
}).success(function(result){
console.log(result);
$scope.reset();
$scope.activePath = $location.path('#/Customers');
});
$scope.reset = function() {
$scope.customer = angular.copy($scope.master);
};
$scope.reset();
};
}
PHP(正在运行)
$app->post('/customers', 'authenticate', function() use ($app) {
// check for required params
verifyRequiredParams(array('first_name'));
$response = array();
$first_name = $app->request->post('first_name');
$last_name = $app->request->post('last_name');
$email = $app->request->post('email');
$mobile_number = $app->request->post('mobile_number');
$home_number = $app->request->post('home_number');
$address_line1 = $app->request->post('address_line1');
$address_line2 = $app->request->post('address_line2');
$city = $app->request->post('city');
$postalcode = $app->request->post('postalcode');
global $user_id;
$db = new DbHandler();
// creating new customer
$customer_id = $db->createCustomer($user_id, $first_name, $last_name, $email, $mobile_number, $home_number, $address_line1, $address_line2, $city, $postalcode);
if ($customer_id != NULL) {
$response["error"] = false;
$response["message"] = "Customer created successfully";
$response["customer_id"] = $customer_id;
echoRespnse(201, $response);
} else {
$response["error"] = true;
$response["message"] = "Failed to create customer. Please try again";
echoRespnse(200, $response);
}
});
但是,对于我的登录脚本,数据似乎没有到达 PHP 文件,其中 $http.post 请求始终在控制台中返回“null”。
请求 2 - Angular.JS(不工作)
function ($scope, $http, $location) {
console.log("REACHED");
$scope.Login = function(customer, LoginForm) {
console.log(customer);
console.log("2: " + JSON.stringify(customer));
console.log("SCOPE: " + customer.email);
$http({
url: "v1/login",
method: "POST",
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: $.param({email: customer.email, password: customer.password})
}).success(function(data, status, headers, config) {
$scope.data = data;
console.log($scope.data);
}).error(function(data, status, headers, config) {
$scope.status = status;
$scope.data = data;
console.log($scope.status + " " + $scope.data);
});
};
}
PHP(不工作)
$app->post('/login', function() use ($app) {
// check for required params
verifyRequiredParams(array('email', 'password'));
$response = array();
$email = $app->request()->post('email');
$password = $app->request()->post('password');
$db = new DbHandler();
// check for correct email and password
if ($db->checkLogin($email, $password)) {
// get the user by email
$user = $db->getUserByEmail($email);
if ($user != NULL) {
$response["error"] = false;
$response['name'] = $user['name'];
$response['email'] = $user['email'];
$response['apiKey'] = $user['api_key'];
$response['createdAt'] = $user['created_at'];
} else {
// unknown error occurred
$response['error'] = true;
$response['message'] = "An error occurred. Please try again";
}
} else {
// user credentials are wrong
$response['error'] = true;
$response['message'] = 'Login failed. Incorrect credentials';
}
echoRespnse(200, $response);
});

我似乎无法弄清楚为什么我的第一个请求(创建新客户有效)但登录不起作用。任何有关此问题的帮助将不胜感激,因为我花了时间在论坛上寻找其他答案,但尚未找到解决此问题的方法。
最佳答案
通常,AJAX 请求失败的原因如下:
- 网址或方法错误
- Cors 请求
- 连接已阻止
既然您已经检查了 DevTools
并确保它不是第一个,并且您正在使用相同的域。我们来讨论第三个。
可以通过chrome://net-internals/#events
调试阻止的连接。发生这种情况的原因包括网络断开
、防火墙问题
。第二个有时非常令人困惑,我猜你正面临着这个问题。我想您被 AdBlock
之类的插件阻止了。
