expressjs mysql更新错误

我使用expressjs与node-mysql模块。 我发布更新操作时遇到此错误

/Users/mac/node_modules/mysql/lib/mysql/client.js:106 cb(err); ^ TypeError: string is not a function at String.CALL_NON_FUNCTION (native) at Query.<anonymous> (/Users/mac/node_modules/mysql/lib/mysql/client.js:106:9) at Query.emit (events.js:64:17) at Query._handlePacket (/Users/mac/node_modules/mysql/lib/mysql/query.js:35:12) at Client._handlePacket (/Users/mca/node_modules/mysql/lib/mysql/client.js:294:14) at Parser.<anonymous> (/Users/mac/node_modules/mysql/lib/mysql/client.js:83:14) at Parser.emit (events.js:64:17) at /Users/mac/node_modules/mysql/lib/mysql/parser.js:75:14 at Parser.write (/Users/mac/node_modules/mysql/lib/mysql/parser.js:580:7) at Socket.<anonymous> (/Users/mca/node_modules/mysql/lib/mysql/client.js:63:16) 

我使用这个动作：

  app.post('/post/:id/edit', function(req, res){ var id = req.params.id; var query = client.query( 'UPDATE '+POST, 'SET title = ?, text = ?', [req.body.title, req.body.text ], ' WHERE id='+id ); res.redirect('/'); }); 

怎么了？

Answer 1

 var query = client.query( 'UPDATE '+POST + ' SET title = ?, text = ?' + ' WHERE id='+id, [req.body.title, req.body.text ] ); 

你正在使用,而不是+

你想连接所有的string部分，然后在最后传递你的参数数组。
