如何在node.js中发布表单数据以测试multer node.js应用程序

Question

使用multer软件包的js应用程序。代码如下所示：

var multer  = require('multer')
var upload = multer({ dest: 'avatars' })

router.post('/users/me/avatar', upload.single('avatar'), (req, res) => {
    res.send()
})

我正在尝试使用SoapUi测试这个端点。

但是，我从节点获得了下面的响应。

Distributors\Node\task-manager\node_modules\multer\index.js:40:19)：

MulterError: wrappedFileFilter的意外字段(C:\Users\pdatta\OneDrive - American )(C:\Users\pdatta\OneDrive -美国轮胎Distributors\Node\task-manager\node_modules\multer\lib\make-middleware.js:114:7) at Busboy.emit (events.js:311:20) at Busboy.emit (C:\Users\pdatta\OneDrive )-美国轮胎Distributors\Node\task-manager\node_modules\busboy\lib\main.js:38:33) at PartStream.(C:\Users\pdatta\OneDrive -美国轮胎Distributors\Node\task-manager\node_modules\busboy\lib\types\multipart.js:213:13) at PartStream.emit (events.js:311:20) at HeaderParser.(C:\Users\pdatta\OneDrive -美国轮胎Distributors\Node\task-manager\node_modules\dicer\lib\Dicer.js:51:16) at HeaderParser.emit (events.js:311:20) at HeaderParser._finish (C:\Users\pdatta\OneDrive )-美国轮胎Distributors\Node\task-manager\node_modules\dicer\lib\HeaderParser.js:68:8) at SBMH。(C:\Users\pdatta\OneDrive -美国轮胎Distributors\Node\task-manager\node_modules\dicer\lib\HeaderParser.js:40:12) at SBMH.emit (events.js:311:20) at SBMH._sbmh_feed (C:\Users\pdatta\OneDrive - American Tire Distributors\Node\task-manager\node_modules\streamsearch\lib\sbmh.js:95:16) at SBMH.push )美国轮胎Distributors\Node\task-manager\node_modules\dicer\lib\HeaderParser.js:46:19) at Dicer._oninfo (C:\Users\pdatta\OneDrive -美式轮胎Distributors\Node\task-manager\node_modules\dicer\lib\Dicer.js:197:25) at SBMH )(C:\Users\pdatta\OneDrive -美国轮胎Distributors\Node\task-manager\node_modules\dicer\lib\Dicer.js:127:10)

请帮我解决这个问题。该文件未保存在目标目录中。

如果你需要其他信息，请告诉我。

尝试将此作为中间件

​

const multer  = require('multer')

const dirStorage =  __dirname +'/avatas';

const storageOption = multer.diskStorage({
    destination: function (req, file, cb) {
      cb(null, req.dirStorageUser);
    },
    filename: function (req, file, cb) {
      cb(null, `new_avatar.png`);
    }
});

const upload = multer({
  storage: storageOption
}).single('upload');


router.post('/users/me/avatar', uploadMiddleware, (req, res) => {
    res.send("");
})


function uploadMiddleware(req, res, next) {

    if (!fs.existsSync(dirStorage)) {
      fs.mkdirSync(dirStorage);
    }

    upload(req, res, function (err) {
      let errorMsg;
      if (err instanceof multer.MulterError) {
        errorMsg = 'Was not possible save image';
      } else if (err) {
        errorMsg = 'Something was wrong on save image';
      }
   
      if (errorMsg) {
        return res.send(errorMsg);
      }
      return res.send("success");
      //next("route");
    });

}
