我正在尝试从我的离子应用程序将用户数据发布到PHP RESTful API。我试着寻找解决方案但没有帮助。我创建了一个包含函数的提供程序,即" onSignup(signupForm)"在点击按钮时调用。
代码如下:
signup(username: string,email: string,password: string): void {
let headers = new HttpHeaders();
headers = headers.set("Content-Type","application/json; charset=UTF-8");
let body= {
name:username, email:email, password:password
};
this.http.post('http://www.something.com/register', JSON.stringify(body),
{headers: headers})
.subscribe(data => {
console.log(data);
});
this.storage.set(this.HAS_LOGGED_IN, true);
this.setUsername(username);
this.events.publish('user:signup');
};
api的代码如下:
<?php
header("Access-Control-Allow-Origin:*");
header("Content-Type: application/json; charset=UTF-8");
require_once '../include/DbHandler.php';
require_once '../include/PassHash.php';
require '.././libs/Slim/Slim.php';
\Slim\Slim::registerAutoloader();
$app = new \Slim\Slim();
/**
* ----------- METHODS WITHOUT AUTHENTICATION -------------------------------
--
*/
/**
* User Registration
* url - /register
* method - POST
* params - name, email, password
*/
$app->post('/register', function() use ($app) {
file_put_contents("logs.txt","/register Route has been visited");
// check for required params
verifyRequiredParams(array('name', 'email', 'password'));
$response = array();
// reading post params
$name = $app->request->post('name');
$email = $app->request->post('email');
$password = $app->request->post('password');
// validating email address
validateEmail($email);
$db = new DbHandler();
$res = $db->createUser($name, $email, $password);
if ($res == USER_CREATED_SUCCESSFULLY) {
$response["error"] = false;
$response["message"] = "You are successfully registered";
} else if ($res == USER_CREATE_FAILED) {
$response["error"] = true;
$response["message"] = "Oops! An error occurred while registereing";
} else if ($res == USER_ALREADY_EXISTED) {
$response["error"] = true;
$response["message"] = "Sorry, this email already existed";
}
// echo json response
echoRespnse(201, $response);
});
我收到的错误是
无法加载资源:服务器响应状态为404(未找到)。
无法加载http://www.something.com/register:预检的响应包含无效的HTTP状态代码404
此API在Postman中运行良好,但在Chrome中运行应用时遇到了问题。
我在API或POST调用期间是否缺少某些内容?
请帮忙。在此先感谢。

我添加了网络标签截图。这就是我在请求和响应标头中获得的内容。我猜这两个标题可能不匹配,但它肯定不会成为CORS问题,因为我可以在没有任何CORS问题的情况下进行GET调用。
添加了包含错误的控制台选项卡屏幕截图:

由于它是从Postman工作而不是你的应用程序,我会好好看看CORS。您需要在请求进入时设置标题,对于发布请求,Angular HttpClient将发送OPTIONS请求。
我不太多使用PHP,但也许这样的东西可以使用
if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, OPTIONS');
header('Access-Control-Allow-Headers: Content-Type');
header('Content-Length: 0');
header('Content-Type: application/json');
die();
}
编辑:由于您使用的是Slim Framework,我假设您提供的代码。您可以根据Slim Framework v2 Docs(不确定您使用的是哪个版本)描述OPTIONS请求。
$app->options('/register', function ($app) {
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, OPTIONS');
header('Access-Control-Allow-Headers: Content-Type');
header('Content-Length: 0');
header('Content-Type: application/json');
die();
});
或者您可以设置标题,如下所述 https://www.slimframework.com/docs/v2/response/headers.html
$app->response->headers->set('Access-Control-Allow-Origin', '*');
$app->response->headers->set('Access-Control-Allow-Methods', 'POST, OPTIONS');
$app->response->headers->set('Access-Control-Allow-Headers', 'Content-Type');
$app->response->headers->set('Content-Type', 'application/json');

尝试
header('Access-Control-Allow-Origin: *');
$dados = file_get_contents('php://input');
您将从角度请求中获取JSON ...
