我试图从一个简单的ajax请求中获取值,但我不明白该怎么做.这是代码：
Rx.Observable
.ajax({ url: 'https://jsonplaceholder.typicode.com/posts',method: 'GET',responseType: 'json' })
.subscribe(function(data) { return data.response; });
我到处搜索,没有简单的解释.
谢谢！
Observable.ajax可以使用以下接口接受字符串或对象：

以下是示例：
const { Observable,combineLatest } = rxjs; // = require("rxjs")
const { ajax } = rxjs.ajax; // = require("rxjs/ajax")
const { map } = rxjs.operators; // = require("rxjs/operators")
// simple GET request example
const simple$= ajax('https://httpbin.org/get');
// POST request example
const complex$= ajax({
url: 'https://httpbin.org/post',method: 'POST',headers: {
'Content-Type': 'application/json','x-rxjs-is': 'Awesome!'
},body: {
hello: 'World!',}
});
const htmlSubscription = combineLatest(simple$,complex$)
.subscribe(([simple,complex]) => {
const simpleResponse = JSON.stringify(simple.response,null,2);
const complexResponse = JSON.stringify(complex.response,2);
document.getElementById('root').innerHTML = `
<div>
<span><b>GET</b> https://httpbin.org/get</span>
<pre>${simpleResponse}</pre>
<span><b>POST</b> https://httpbin.org/post</span>
<pre>${complexResponse}</pre>
</div>`;
});
<script src="https://unpkg.com/rxjs/bundles/rxjs.umd.min.js"></script> <div id="root">loading ...</div>
