我尝试使用以下代码从我的角度应用程序向其余服务器发送http.post请求:
我正在使用:import { Http } from '@angular/http';
let headers = new Headers();
headers.append('Content-Type', 'application/json');
let data: string = 'wing,wheel';
this.http.post('http://172.16.2.209:3000/api/AddPartList?access_token=xxxxxxxxxxxx',{headers: headers},data)
但我一直收到错误Response with status: 422 Unprocessable Entity for URL
我想做的curl命令是:
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{ \
"$class": "org.blockaviation.AddPartList", \
"partListId": "1", \
"partList": "wing,wheel", \
"plane": "resource:org.blockaviation.Plane#Plane_001" \
\
}' 'http://172.16.2.209:3000/api/AddPartList'
有谁知道我做错了什么或如何正确地做到这一点?

您应该将标头放在RequestOptions对象中,如下所示:
import { Http, Headers, RequestOptions } from '@angular/http';
private requestOptions = new RequestOptions({
headers: new Headers({
'Content-Type': 'application/json'
})
});
this.http.post(this.url, data, this.requestOptions);
