如何读取组件中的http状态代码错误
how to read http status code error in component
我知道之前有人问过这个问题,但我似乎找不到答案,如何从 http.. 读取状态代码?
this.bookingService.save(this.param)
.subscribe(
data =>
swal({
"title": "Succes!",
"text": "Your data saved",
"type": "success",
"confirmButtonClass": "btn btn-secondary m-btn m-btn--wide"
}),
error => console.log('error'),
() => this.router.navigate('Succes')
);
您可以从错误中获取状态码,
this.bookingService.save(this.param).subscribe(
data =>{
console.log(data);
},
(err) => {console.log(err)});
要取回错误消息,请添加一个将 return 错误对象的 catch:
save(book){
return this.http.post('http:..../',book)
.map(res => res)
.catch(this.handleError);
}
private handleError(error: any) {
let errMsg = (error.message) ? error.message : error.status ? `${error.status} - ${error.statusText}` : 'Server error';
return Observable.throw(error);
}
