如何使用JSON数据来自Angular2中的PHP文件？(how to use JSON data Coming from PHP file in Angular2?)
export class LoginComponent
{
getdata : string;
public data;
username : any ;
password : any ;
constructor(private http: Http){}
login() {
var headers= new Headers({'Content-Type' : 'application/x-www-form-urlencoded '});
var body = JSON.stringify({
user : this.username,
pwd : this.password,
})
this.http.post('.../pos_system/Widgets/Login.php',body, {
headers:headers; })
.map(res => res.json())
.map(res => {
if(res.success)
{
this.msg="Login Complete";
}
else{
this.msg1="username and password is wrong";
}
})
.subscribe(
data =>this.getdata = JSON.stringify(data),
err => console.error(err),
() => console.log('done'));
}
}
这是我的Angular2部分，我在res获取来自php文件的JSON数据。现在我想在我的angualr2部分使用这个响应。我想使用json data中用户的显示用户名。如何在angular2中做到这一点？
export class LoginComponent { getdata : string; public data; username : any ; password : any ; constructor(private http: Http){} login() { var headers= new Headers({'Content-Type' : 'application/x-www-form-urlencoded '}); var body = JSON.stringify({ user : this.username, pwd : this.password, }) this.http.post('.../pos_system/Widgets/Login.php',body, { headers:headers; }) .map(res => res.json()) .map(res => { if(res.success) { this.msg="Login Complete"; } else{ this.msg1="username and password is wrong"; } }) .subscribe( data =>this.getdata = JSON.stringify(data), err => console.error(err), () => console.log('done')); } }This is my Angular2 part here i m getting JSON data from php file in res.Now I want to use this response in my angualr2 part.I want to use display username of the user which is in json data.so how to do that in angular2?

只需进行此更改即可，例如this.msg=res.username; 这将在消息中显示用户名。 注意：你需要在php文件中执行此操作。
$data=array(); $df=json_decode(file_get_contents("php://input")); $nam=$df->user; $pws=$df->pwd; $select=mysql_query("SELECT * FROM userData WHERE username='$nam' AND password='$pws'")or mysql_error(); $sql=mysql_num_rows($select); if($sql>0) { while($row=mysql_fetch_array($select)) { $data['success']=true; $user=$row['username']; $data['username']=$user; } } echo json_encode($data);it's simple just make this change, for Example this.msg=res.username; this will display username in message. note: you need to do this in php file.
$data=array(); $df=json_decode(file_get_contents("php://input")); $nam=$df->user; $pws=$df->pwd; $select=mysql_query("SELECT * FROM userData WHERE username='$nam' AND password='$pws'")or mysql_error(); $sql=mysql_num_rows($select); if($sql>0) { while($row=mysql_fetch_array($select)) { $data['success']=true; $user=$row['username']; $data['username']=$user; } } echo json_encode($data);更多推荐
