Angular:将Http的RequestOptions与HttpClient一起使用

本文介绍了Angular:将Http的RequestOptions与HttpClient一起使用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在从 Http 迁移到 HttpClient 我习惯于在http请求中添加一些标头，如下所示:

i'm migrating from Http to HttpClient I'm used to add some headers to my http requests like the following with :

import { RequestOptions, Request, RequestMethod, Headers } from '@angular/http'; this.pass = btoa(cuid + ': '); this.pass = "Basic " + this.pass; this.header = new Headers(); this.header.set("Authorization", this.pass); let options = new RequestOptions({ headers: this.header }); return this.http.post(myServiceUrl, {}, options)

现在，当迁移到httpClient时，我已经尝试过:

Now when migrating to httpClient , i ve tried this :

import {HttpClient, HttpHeaders} from '@angular/common/http'; const header = new HttpHeaders(); const pass = 'Basic ' + btoa(cuid + ': '); header.set('Authorization', pass); const options = ({ headers: header }); return this.httpClient.post(myServiceUrl, {}, options);

但是您可以看到ivent找到了 RequestOptions 的等效项，并且整个处理都无法添加相同的标头.

but as you can see ivent find the equivalent of RequestOptions , and the whole treatment failed to add the same headers.

建议?

推荐答案

HttpClient.post方法具有以下签名:

post(url: string, body: any | null, options: OptionsType)

OptionsType为以下字符(等同于RequestOptions)

Where the OptionsType is the following (equivalent to RequestOptions)

{ headers?: HttpHeaders | { [header: string]: string | string[] }; observe?: "body"; params?: HttpParams | { [param: string]: string | string[] }; reportProgress?: boolean; responseType: "arraybuffer"; withCredentials?: boolean; };

您可以从那里分配标题或参数，例如:

From there you can assign you header or params, like:

const options = { headers: new HttpHeaders().append('key', 'value'), params: new HttpParams().append('key', 'value') } this.httpClient.post(url, {}, options)
