examples目录里的complex例程如何增删查？ about node-odata HOT 9 CLOSED

request data 只接受 JSON 格式的数据, JavaScript object 是不行的, 你可以尝试:

POST /orders

{"custom":{"id":"1","name":"john"},"orderItems":[{"quantity":10,"product":{"id":"1","name":"com","price":2.1}}]}

from node-odata.

Thx，it's done.

from node-odata.

还有一个问题：
.before(function (entity) {...}) 这个before方法里可以对request内容进行更改吗？这样可以不必重定义post等方法？ 怎么做？

from node-odata.

可以的.

server.resource('orders', order)
.post().before(function (entity) {
    entity.custom.name = "zack";
});

from node-odata.

@TossShinHwa 你好，如果request data的json数据里面包含了中文，POST会失败。都是英文的话不会返回ERROR。试试下面这段代码呢？看你那边会不会。

var http = require('http');

var bookBody = {
    "title": "黑客与画家",
    "price":9.89
}

var bookBodyString = JSON.stringify(bookBody);
var options = {
    host: 'localhost',
    port:'3000',
    path: '/books',
    method: 'POST',
    headers: {
        'Accept': '/',
        'Content-Type':'application/json',
        'Content-Length': bookBodyString.length
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function(data) {
        console.log(data);
    });

    res.on('err',function(data){
        console.log(data);
    });
});


req.write(bookBodyString);
req.end();`

from node-odata.

这么取长度是不对的.

'Content-Length': bookBodyString.length

你可以考虑去掉这个参数, 让他自动计算, 就不会报错了.

from node-odata.

谢谢，果然是中文的坑。或者改成下面获取长度也可以避免。
Buffer.byteLength(bookBodyString, 'utf8')

from node-odata.

Great! 我之前都没有手动去处理过 req 的 length 问题, 学习了.

node test.js
{"title":"黑客与画家","price":9.89,"id":"7f9224d6-3b8c-4a14-9606-b665e17cec7d"}

我刚刚看到，调试的时候也是报错误，后台我对比curl，去掉了 content-length，就ok了
