如何使用节点的rest客户端上载文件

I have a REST client on node, and I'm trying to upload pdf a file to another REST webserver which provides the ability to parse my pdf and extract some data. Basically it is a service. The npm package that I use is: https://www.npmjs.com/package/node-rest-client. If there are other rest clients, I can use those as well. The rest api I need to use is described below:

我在节点上有一个REST客户端，我正在尝试将pdf文件上传到另一个REST Web服务器，它提供了解析我的pdf并提取一些数据的能力。基本上它是一种服务。我使用的npm包是：https：//www.npmjs.com/package/node-rest-client。如果还有其他休息客户，我也可以使用它们。我需要使用的其余api如下所述：

POST    /         ; Uploads a new PDF document via a form <br>
POST    /file     ; Uploads a new PDF document via bytestream

The question is how to upload the file. Also, I would like to see how to store the file at the other end.

问题是如何上传文件。另外，我想看看如何在另一端存储文件。

#1

You can use npm module request to upload the file. Here is a working example

您可以使用npm模块请求上传文件。这是一个有效的例子

var request = require('request');
var fs = require('fs');
request({
  method: 'PUT',
  preambleCRLF: true,
  postambleCRLF: true,
  uri: 'http://yourdomain/file',
  multipart: [
    {
      'content-type': 'application/pdf',
      body: fs.createReadStream('image.png') 
    }
  ]    
},
function (error, response, body) {
  if (error) {
    return console.error('upload failed:', error);
  }
  console.log('Upload successful!  Server responded with:', body);
});

For receiving at the server side with node you can use modules like busboy. Here is a demo for this

要在服务器端接收节点，您可以使用busboy等模块。这是一个演示

var busboy = require('connect-busboy');
app.use(busboy());
app.use(function(req, res) {
  if (req.busboy) {
    req.busboy.on('file', function(fieldname, file, filename, encoding,    mimetype) {
      // move your file etc
    });
    req.pipe(req.busboy);
  }
});

You can use request.

您可以使用请求。

There is an example for that

有一个例子

fs.createReadStream('file.pdf').pipe(request.post('http://example.com/file'))
