The post request becomes get

[MaJiangBo]

my code:
public interceptBefore(request: InterceptedRequest): InterceptedRequest {

    let jwt = localStorage.getItem('token');
    let authHeader = new Headers();
    if(jwt) {
        authHeader.append('Authorization', 'Bearer ' + jwt);
    }
    authHeader.append('Content-Type', 'application/json;charset=UTF-8');
    request.interceptorOptions={
        headers: authHeader,
    }
    // request.options={
    // headers: authHeader,
    // }
    console.log("请求地址为："+ request.url)
    return request;
}

when I use
request.options={
headers: authHeader,
}
The post request becomes get

but use:
request.interceptorOptions={
headers: authHeader,
}
don't have that question.
