Question

我在Angular 6中有一项服务，我正在尝试更改记录但是它说我没有被授权。

现在我有这个：

const httpOptions = {
  headers: new HttpHeaders({'Content-Type': 'application/json'})
};

  update(id, title, content) {
    const updateData = { id: id, title: title, content: content };
      return this.http.put(`http://myurl/${id}`, updateData, httpOptions);
  }

我的问题是：

如何向httpOptions添加基本授权，还是直接将其添加到更新方法？

Answer 1

您可以在标题中附加基本授权，如下所示：

var headers_object = new HttpHeaders();
headers_object.append('Content-Type', 'application/json');
headers_object.append("Authorization", "Basic " + btoa("username:password"));

const httpOptions = {
  headers: headers_object
};

Answer 2

查看angular.io文档，它非常简单。

const httpOptions = {
  headers: new HttpHeaders({
    'Content-Type':  'application/json',
    'Authorization': 'Basic my-auth-token'
  })
};

你可以像你一样使用httpOptions常数。

Answer 3

只需在标题中添加您的令牌/授权，就像这样 -

let httpHeaders = new HttpHeaders()
              .set('authorization', this.authorizationHeaderValue)
              .set('Content-Type', application/json);

两者都有set和append等方法。 set构造一个具有新值的新主体，append构造一个带有附加值的新主体

PS：我假设变量（this.authorizationHeaderValue）值包含Bearer或Basic或其他任何需要的值，请相应更改。

const httpOptions = {
  headers: new HttpHeaders(
    {
      'Content-Type': 'application/json',
      'Authorization': `Basic ` + btoa('user:password'),
    }
  )
};


return this.http.post<any>(
      `apilink`,{},
      httpOptions
    ).pipe(map(res => {
      return res;
}));

Answer 5

httpClient中通过httpOptions传递基本身份验证的HttpClient在Angular 6中有所不同

let httpHeaders= new HttpHeaders();
httpHeaders.append('Content-Type', 'application/json');
httpHeaders.append("Authorization", "Basic " + btoa("username:password"));

const httpOptions = {
  headers: httpHeaders
};

update(id, title, content) {
    const updateData = { id: id, title: title, content: content };
      return this.http.put(`http://myurl/${id}`, updateData, httpOptions);
  }

Answer 6

从'@ angular / common / http'导入{HttpClient，HttpHeaders};

var headers = new HttpHeaders（）;

var token = localStorage.getItem（'token'）;

headers.append（'Content-Type'，'application / json'）;

headers.append（“ Authorization”，“ Basic” +令牌））;

const httpOptions = { 标头：标头 };

Answer 7

许多服务器需要额外的标头来进行保存操作。例如，服务器可能需要授权令牌或“Content-Type”标头来明确声明请求正文的 MIME 类型。就您而言，您可以通过以下代码进行基本授权。

import { HttpHeaders } from '@angular/common/http'; 
const httpOptions = {headers: new HttpHeaders({
'Content-Type':  'application/json',
Authorization: 'my-auth-token' })};

您可以在发出下一个请求之前更新授权标头

httpOptions.headers =  httpOptions.headers.set('Authorization', 'my-new-auth-token');
