Question

我想使用pipe将可读流传递给帖子请求正文，但我遇到了麻烦。这是我的代码：

var request = require('request');  
var fs = require('fs');   
var source = fs.createReadStream('./originalJsonDataWithObject.json');  //creating a read stream to read the file 
    source.pipe(request.post('http://localhost:3030/decompress'));  //piping it to the post request

Answer 1

var request = require('request');
var fs = require('fs');
var file = fs.createReadStream('./originalJsonDataWithObject.json');
var req = request.post({
  url: 'your post url',
  headers: {<headers>},
  body: file
});

POST请求正文参数是您实际发送的数据请求。这些数据可以有多种形式（流，缓冲，字符串等）你不需要管道。如果您需要发布JSON数据，可以执行以下操作：

    const req = request.post({
        url: 'http://localhost:3030/decompress',  
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify(<your JSON data>)                
    });

Answer 2

var request = require('request');  
    var fs = require('fs');
    var file = fs.createReadStream('./originalJsonDataWithObject.json');// This line opens the file as a readable stream.
    http.get(url, function (response) {
        response.pipe(file);// this line just create a stream and move to file into stream
    });

如何将数据从文件传输到节点js中的post body请求
