HTTP Post with no body in Angular
提问by William Hampshire
I'm wondering how to send an HTTP post request without a body (specifically in Angular). Here's what I'm doing now, but I'm getting the error Expected 2-3 arguments, but got 1)
.
我想知道如何在没有正文的情况下发送 HTTP post 请求(特别是在 Angular 中)。这就是我现在正在做的事情,但我收到了错误Expected 2-3 arguments, but got 1)
。
I realize the second argument is for the body, but I'm not sending that to the server (yes, I understand that a POST call changes the state of a system and have looked into THISquestion).
我意识到第二个参数是针对主体的,但我没有将其发送到服务器(是的,我知道 POST 调用会更改系统的状态,并且已经研究了这个问题)。
postRequest(id) {
this.http.post('/api?data=' + id).map(
(response) => {
return response;
}
)
}

Looks like this is the appropriate answer:
看起来这是正确的答案:
postRequest(id) {
this.http.post('/api?data=' + id, null).map(
(response) => {
return response;
}
)
}

If null is not working(4XX error client side), try with {} JSON
如果 null 不起作用(4XX 错误客户端),请尝试使用 {} JSON
postRequest(id)
{
this.http.post('/api?data=' + id, {}).map((response) => {return response;})
}
