使用php API从angular6中的httpClient响应中检索参数值？
使用php API从angular6中的httpClient响应中检索参数值？
提问于 2018-06-25 04:36:16
我在angular中有一个方法，它将值发布到php api，当http post成功时，我得到一个json响应，但当我试图访问res.status或json对象中的任何参数时，我得到的是Property 'status' does not exist on type 'Object'。如何获取response对象中参数的值？
这是我的angular类
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");
}
);
}下面是我的PHP：(我知道准备好的语句，这里尽量简单)：
<?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.

假设您已经为响应定义了一个接口：
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)如果没有可用的类型定义，则返回
this.http.post<any>('http://myhost.com/phpapi/api.php',this.myData)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
