如何使用成角度的HttpClient请求以这种格式从.json文件添加,更新和删除testDrives项目:
{
"cars": ["BMW", "Audi"],
"testDrives": [
{
"start": "2020-06-03T11:00:00.000Z",
"end": "2020-06-03T12:00:00.000Z",
"name": "BMW",
},
{
"start": "2020-06-03T14:00:00.000Z",
"end": "2020-06-03T15:30:00.000Z",
"name": "Audi",
}
]
}
我尝试使用标头,斜杠和id,但似乎不起作用:
this.http
.get(this.file+'testDrives[0]').subscribe(res => console.log(res));
