使用 php API 从 angular6 中的 httpClient 响应中检索参数值?

Question

我在 angular 中有一个将值发布到 php API 的方法，当 http post 成功时，我得到一个 json 响应，但是当我尝试访问 res.status 或 json 对象中的任何参数时，我得到Property 'status' does not exist on type 'Object'。如何获取响应对象中参数的值？

这是我的角度课

export class QuizComponent implements OnInit {
constructor(private http: HttpClient) { }

myData = { param1: 'This is param 1', param2: 'this is param 2' }

sendmydata(){
const req = this.http.post('http://myhost.com/phpapi/api.php',this.myData)
.subscribe(
res => {
console.log(res);
// how can I access res.status here?
res.status;//this line says Property 'status' does not exist on type 'Object'
},
err => {
console.log("Error occured");
}
);
}

这是我的PHP： (我知道准备好的陈述，只是在这里保持简单(：

<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
header("Access-Control-Allow-Methods: POST");
header("Access-Control-Max-Age: 3600");
header("Access-Control-Allow-Headers: Content-Type, Access-Control- 
Allow-Headers, Authorization, X-Requested-With");

$db = "dbname";//Your database name
$dbu = "dbuser";//Your database username
$dbp = "dbpass";//Your database users' password
$host = "localhost";//MySQL server - usually localhost

$dblink = mysql_connect($host,$dbu,$dbp);
$seldb = mysql_select_db($db);

$postdata = file_get_contents("php://input");
$request = json_decode($postdata);
$item1 = $request->param1;
$item2 = $request->param;
$sql = mysql_query("INSERT INTO `$db`.`table` (`id`,`item1`,`item2`) 
VALUES ('','$item1','$item2');");
if($sql){
if (strcmp($item1, "") != 0) {
echo '{"status":"ok"}';
}
}else{
echo '{"status":"error"}';
}
mysql_close($dblink);//Close off the MySQL connection to save resources.
?>

假设您为响应定义了接口：

interface Response {
status: string;
}

将类型信息添加到post调用中：

this.http.post<Response>('http://myhost.com/phpapi/api.php',this.myData)

或任何(如果没有可用的类型定义(

this.http.post<any>('http://myhost.com/phpapi/api.php',this.myData)
