Question

我正在尝试使用Restify模块将图像文件上传到Rest服务器（Confluence更具体），但是收到Assertion错误。我不确定我是否使用正确的方法将文件上传到REST服务器。有人能指出我正确的方向吗？

这是我的尝试 -

var restify = require('restify');
var header = {'Authorization': 'Basic xxxxx', 'content-type': 'multipart/form-data'};
var client = restify.createJsonClient({
   url: 'http://www.testsite.com',
   version: '*',
   headers: header
});
var image = "c:\\Users\\abc\\Documents\\bbb.jpg";           
var fileStream = fs.createReadStream(image);
var stat = fs.statSync(image);
var size = stat["size"];
var param = "?pageId=123&filename=mynewimage&mimeType=image%2Fjpeg&size=" + size;       
fileStream.pipe(
    client.post("/plugins/drag-and-drop/upload.action"+param, function(err, req, res, obj) {
        if (err) {
            return err;
        }

    })
);

更新：

这是一个断言错误我得到assert.js：86

throw new assert.AssertionError({
        ^

我一直在努力发送包含multipart/form-data的请求并使用restify 5在API上处理此请求。在@mscdex回答后，我想出了以下代码来处理这两种情况：

"use strict"

const restify  = require('restify'),
  plugins  = require('restify-plugins'),
  fs       = require('fs'),
  request  = require('request'),
  FormData = require('form-data');

var server = restify.createServer();
server.use(plugins.multipartBodyParser());  // Enabling multipart

// Adding route
server.post('/upload', (req, res, next) =>{
    /**
    * Processing request containing multipart/form-data
    */
    var uploaded_file = req.files.mySubmittedFile;  // File in form

    //Reading and sending file
    fs.readFile(uploaded_file.path, {encoding: 'utf-8'}, (err, data)=>{
        // Returning a JSON containing the file's name and its content
        res.send({
            filename: uploaded_file.name,
            content: data
        });
        next()
    });
});

// Launching server at http://localhost:8080
server.listen(8080, start);

// Client request
function start(){
    // Making a request to our API using form-data library
    // Post file using multipart/form-data
    var formData = {
        mySubmittedFile: fs.createReadStream('/tmp/hello.txt')
    }
    request.post({'url': 'http://localhost:8080/upload', formData: formData}, function(err, res, body){
        console.log("Response's body is: "+ body);
    });
}

使用：

form-data@2.2.0
request@2.81.0
restify@5.0.1
restify-plugins@1.6.0
node @ 6.11.1

我尝试不使用库form-data和request来仅使用restify / http但我最终得到了一个可怕的长代码。

要发送multipart/form-data，您必须使用restify以外的库，因为它不支持Content-Type。

您可以使用支持内置multipart/form-data http请求的request。
