node.js - 解析回调请求时出现多方错误

Question

我正在使用多方。它工作正常，但突然抛出错误。

错误

err: { Error: stream ended unexpectedly
    at Form.<anonymous> (/user_code/node_modules/multiparty/index.js:754:24)
    at emitNone (events.js:91:20)
    at Form.emit (events.js:185:7)
    at finishMaybe (_stream_writable.js:514:14)
    at endWritable (_stream_writable.js:524:3)
    at Form.Writable.end (_stream_writable.js:489:5)

    at process._tickDomainCallback (internal/process/next_tick.js:128:9) status: 400, statusCode: 400 }

代码

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

var multiparty = require('multiparty');
var http = require('http');
var util = require('util');

exports.helloWorld = functions.https.onRequest((request, response) => {
                                               var body = "";
                                               var POST = {};
                                               var form = new multiparty.Form();
                                               form.on('error', function(err) {
                                                       console.log('Error parsing form: ' + err.stack);
                                                       });
                                               form.parse(request, function(err, fields, files) {
                                                          response.status(500).send({
                                                                                    message: err
                                                                                    });
                                                          })
                                               });
});

“流意外结束” 错误意味着底层 TCP 套接字在收到完整的多部分表单之前已关闭。

正如您所说，这以前是有效的，您应该检查您向其发出请求的服务器是否存在任何可能提前关闭响应的错误。一个常见原因是响应数据的大小大于服务器或请求/响应 header 所接受的大小。
