Question

我正在尝试将数据发布到服务器。我的php方面运行正常。当我尝试使用postman post工作时。但从角度来看，我得到405（方法不允许）错误：

zone.js:2935 OPTIONS http://angularslim.local/public_html/users 405 (Method Not Allowed)

Failed to load http://angularslim.local/public_html/users: Response for preflight has invalid HTTP status code 405。

我的代码如下：在我的服务中，我有以下代码。

@Injectable()
export class AuthService {
    constructor(private http: Http) {}
    register(user:User){
        this.http.post("http://angularslim.local/public_html/users", user).subscribe((res: Response) => {
            console.log("inside");
        })
    }

在我的php部分，我确实有这些行

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Content-Type");

Answer 1

您是否尝试通过JSON.stringify（用户）传递表单值。我以前遇到过同样的问题。后来我发现我的问题是那个。

this.http.post("your api url", JSON.stringify(user))
    .subscribe(
    (val) => {
            console.log("POST call successful value returned in body", val);
});

希望这适合你。

您需要允许交叉起源和方法

https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS

另请尝试https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-Methods

另外，我建议您使用HttpClient（不推荐使用http）和HttpResponse

Answer 3

If you use Slim, this is mostly because your Javascript code sends HTTP OPTIONS request while there is no route that handle HTTP OPTIONS.

You need to add a route that handle OPTIONS request or modify any Javascript code that cause preflight request to be sent (by making it a simple request. Take a look at this question Why is an OPTIONS request sent and can I disable it?).

To add route that handle OPTIONS

$app->options('/users', function ($request, $response, $args) {
     //do something here
]);
