我是Angular 2中的新手。它似乎是starnge,但我需要将form
发送到外部链接,而且,我需要在发布请求后将用户重定向到此页面...
<form id="Form" method="post" action="http//somelink.com" target="TheWindow">
<input type="hidden" name="linkname" value="someValue" />
</form>
在我通过JQuery提出这样的请求之前:
<script>
$( document ).ready(function() {
$( ".btnUpgrade" ).on( "click", function(){
window.open('', 'TheWindow');
document.getElementById('Form').submit();
});
});
</script>
但现在我陷入了困境,不知道如何在Angular 2中做到这一点。我阅读了很多主题,但他们无助。我尝试了window.location.href = '...';
,但它仅对Get请求有用,对帖子没用。任何帮助表示赞赏。
更新 我尝试过(服务中):
submitHiddenForm() {
var headers = new Headers();
headers = this._httpClient.createCustomHeader();
var url = 'http//somelink.com';
var body = 'linkname=someValue';
return this.http.post(url, body, headers).map(this.extractData).catch(this.handleError);
}
在组件中:
submitHiddenForm() {
this._upgradeService.submitHiddenForm().subscribe (data => {
window.location.href = 'http://somelink.com'; },
error => {console.log('Error while redirecting!'); });
}
我有错误:
XMLHttpRequest cannot load http://somelink.com. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.
在我的POST请求中,我有这样的标题:
createCustomHeader(): Headers {
var headers = new Headers();
headers.append('Access-Control-Allow-Origin', '*');
headers.append('Access-Control-Allow-Headers', 'origin, x-requested-with, x-http-method-override, content-type');
headers.append('Access-Control-Allow-Methods', 'POST');
headers.append('Access-Control-Allow-Credentials', 'true');
return headers;
}
答案 0 :(得分:-1)
根据帖子请求的状态代码尝试此操作
this.http.request(new Request(this.requestoptions))
.subscribe(res => {
if (res[0].status == 201) {
this.router.navigateByUrl('..URL here..');
}
console.log(res[0].json);
},
err => {
console.log(err);
})
