带有 woocommerce rest api 的 Ionic3 有发布请求? [英] Ionic3 with woocommerce rest api having post request?

问题描述

我是 woocommerce 和 Ionic 的新手，我正在尝试创建一个以 woocommerce 作为后端的应用程序我已经在项目中实现了基于 get 请求的 rest api，但我无法使用 post 请求实现 api.我尝试过的功能woocommerce create order api 的 post 请求写如下.

I am new to both woocommerce and Ionic and am trying to create an application with woocommerce as backend I have implemented the get request based rest apis in project but am unable to implement the apis with the post request.the function I tried to write for post request to woocommerce create order api is as follows.

  postOrder(postparams){
        var headers = new Headers();
        headers.append("Accept", 'application/json');
        headers.append('Content-Type', 'application/json' );
        headers.append('consumer_key', 'the key comes here');
        headers.append('consumer_secret', 'the secret comes here');
        let options = new RequestOptions({ headers: headers });
        return this.http.post(this.wc_api_path,postparams,options).map(res => res.json());
  }

但这似乎不起作用.

我已经参考了本教程 本文档 本文档 但我无法理解该问题并实施 api.如果可以解释一下，那就太好了一个例子.

I have already referred to This tutorial This Doc This Doc but am unable to understand the issue and implement the api.it would be great if it could be explained with an example.

推荐答案

这是 CORS 的工作方式(使用跨域请求时).使用 CORS，远程 Web 应用程序(这里是域 mydomain.org 的应用程序)选择是否可以通过一组特定的标头来处理请求.

This is the way CORS works (when using cross domain requests). With CORS, the remote Web application (here the one with domain mydomain.org) chooses if the request can be served thanks to a set of specific headers.

CORS 规范区分了两种不同的用例:

The CORS specification distinguishes two distinct use cases:

简单请求.如果我们使用 HTTP GET、HEAD 和 POST 方法，则此用例适用.对于 POST 方法，仅支持具有以下值的内容类型:text/plain、application/x-www-form-urlencoded 和 multipart/form-data.

Simple requests. This use case applies if we use HTTP GET, HEAD and POST methods. In the case of POST methods, only content types with the following values are supported: text/plain, application/x-www-form-urlencoded and multipart/form-data.

预检请求.当简单请求"用例不适用时，会发出第一个请求(使用 HTTP OPTIONS 方法)以检查在交叉上下文中可以做什么.域请求.发送 OPTIONS 请求的不是 Angular2，而是浏览器本身.这与 Angular 无关.

Preflighted requests. When the ‘simple requests’ use case doesn’t apply, a first request (with the HTTP OPTIONS method) is made to check what can be done in the context of cross-domain requests. It's not Angular2 that sends the OPTIONS request but the browser itself. It's not something related to Angular.
