我发出一个POST请求,请求就位,等待它最终失败.我监视了Nginx日志和节点服务器日志,请求甚至没有注册.除了另一位同事之外,这对我测试过的任何人都有效.如果我使用边缘浏览器或其他计算机,它可以正常工作.
我试图向其他(自定义)服务器发出POST请求,并且它也挂起了那里的选项.我也用jQuery发出了POST请求,它也失败了.
也许值得注意的是我正在使用withCredentials标志.

let headers = new Headers();
headers.append('Content-type','application/json');
return this.http
.post(endpoint,JSON.stringify(user),{

我在我的组件中订阅了这个电话：
this._accountService.login(this.user)
.subscribe(res => {
console.log("logged in!");
if (res.json().status === "success") {
window.location.href = `/home/${this.org}/${this.product}`;
}
else {
// What other options are there?
console.log("Do something else maybe?");
}
},err => {
this.invalidLogin = true;
console.log("Ye shall not pass!");
});

我真的猜测这与我浏览器中缓存的内容有关,但我真的找不到什么.我已经清除了所有可以存储的cookie和任何东西.我还能在哪里检查清楚的事情？这显然是我的电脑/浏览器(以及另一个不幸的人)本地的东西.
解决方法
请尝试订阅()到observable.
return this.http
.post(endpoint,{
headers: headers,}).subscribe(() => console.log("POST done!"));
