使用Express.js在服务器上发送POST请求

I'm running into a small issue with something I thought was possible.

我遇到了一些我认为可行的小问题。

I want to have two express routes, one GET route /post-data and one POST route /post-recieve.

我想有两条快速路线,一条GET路线/后期数据和一条POST路线/后接收。

The code would look something like this:

代码看起来像这样:

app.get('/post-data', (req, res, next) => { 
  //set url to '/post-recieve' and set body / headers
})  

app.post('/post-recieve', (req, res, next) => {
  return res.json(res.body)
})

Now, when you visit /post-data you should be instantly redirected to /post-recieve except if you look in the developer console you should see that the method for the document is POST and not a normal GET request.

现在,当您访问/发布数据时,您应该立即重定向到/后接收,除非您查看开发人员控制台,您应该看到该文档的方法是POST而不是正常的GET请求。

Is this possible?

这可能吗?

I know you can use a library like request to make a HTTP post request to an endpoint, but I'm talking about actually sending the user to the page via a POST request.

我知道您可以使用像请求这样的库来向端点发出HTTP post请求,但我所说的实际上是通过POST请求将用户发送到页面。

3 个解决方案

The only way to change the client's request method from GET to POST programmatically is to create a form containing hidden elements with method="post" and action="/post-receive", then using client-side JavaScript to automatically submit the form.

以编程方式将客户端的请求方法从GET更改为POST的唯一方法是使用method =“post”和action =“/ post-receive”创建包含隐藏元素的表单,然后使用客户端JavaScript自动提交表单。

Any HTTP redirects in response to a GET request will also be GET.

响应GET请求的任何HTTP重定向也将是GET。

This feels so dumb, but it might be the only way???

这感觉很愚蠢,但它可能是唯一的方法???

function postProxyMiddleware (url, data) {
  return (req, res, next) => {
    let str = []
    str.push(`<form id="theForm" action="${url}" method="POST">`)
    each(data, (value, key) => {
      str.push(`<input type="text" name="${key}" value="${value}">`)
    })
    str.push(`</form>`)
    str.push(`<script>`)
    str.push(`document.getElementById("theForm").submit()`)
    str.push(`</script>`)
    return res.send(str.join(''))
  }
}

app.get('/mock', postProxyMiddleware('/page', exampleHeaders))

You can use request-promise to post the data to a url. So, initiate with this function and you can get the data in the api url

您可以使用request-promise将数据发布到URL。因此,使用此功能启动,您可以在api url中获取数据

const request = require('request');
const rp = require('request-promise');

let req = {
        "param1" : "data1",
        "param1" : "data2"       
    }    
    rp({
        method: 'POST',
        uri: 'http://localhost:3000/post-data/',
        body: req,
        json: true // Automatically stringifies the body to JSON
        }).then(function (parsedBody) {
                console.dir(parsedBody);
                return parsedBody;
                // POST succeeded...
            })
            .catch(function (err) {
                console.log(err+'failed to post data.');
                return err+'failed to post data.';
                // POST failed...
        });

Apologies If I get your question wrong.

道歉如果我的问题出错了。
