我正在尝试使用Multer包上传任何文件.当我在我的server.js文件中使用以下代码时它工作正常.

var express = require('express'),
    app = express(),
    multer = require('multer');
app.configure(function () {
    app.use(multer({
        dest: './static/uploads/',
        rename: function (fieldname, filename) {
            return filename.replace(/\W+/g, '-').toLowerCase();
        }
    }));
    app.use(express.static(__dirname + '/static'));
});

app.post('/api/upload', function (req, res) {
    res.send({image: true, file: req.files.userFile.originalname, savedAs: req.files.userFile.name});
});

var server = app.listen(3000, function () {
    console.log('listening on port %d', server.address().port);
});

我想要的是将文件存储在不同的位置.我曾尝试过代码,但它对我不起作用.

var express = require('express'),
    app = express(),
    multer = require('multer');
app.configure(function () {
    app.use(multer({
        //dest: './static/uploads/',
        rename: function (fieldname, …

我想用格式的字符串解析带有时区的日期"31-12-2014 18:09 +05:30".我尝试使用"d-MM-yyyy HH:mm ZZ"和使用简单日期格式进行解析"d-MM-yyyy HH:mm Z".但它给了我一个无比例的日期例外.这该怎么做？请帮我.

我正在尝试将 XML 数据加载到 Hive 中，但出现错误：

java.lang.RuntimeException: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while processing row {"xmldata":""}

我使用的 xml 文件是：

<?xml version="1.0" encoding="UTF-8"?>
<catalog>
<book>
  <id>11</id>
  <genre>Computer</genre>
  <price>44</price>
</book>
<book>
  <id>44</id>
  <genre>Fantasy</genre>
  <price>5</price>
</book>
</catalog>

我使用的配置单元查询是：

1) Create TABLE xmltable(xmldata string) STORED AS TEXTFILE;
LOAD DATA lOCAL INPATH '/home/user/xmlfile.xml' OVERWRITE INTO TABLE xmltable;

2) CREATE VIEW xmlview (id,genre,price)
AS SELECT
xpath(xmldata, '/catalog[1]/book[1]/id'),
xpath(xmldata, '/catalog[1]/book[1]/genre'),
xpath(xmldata, '/catalog[1]/book[1]/price')
FROM xmltable;

3) CREATE TABLE xmlfinal AS SELECT * FROM xmlview;

4) SELECT * FROM xmlfinal WHERE …

所以我有这个图像,我按下它应该显示一个表格.我试图通过代码和警报工作做一些警报,但表单仍未显示.
