JSON格式(通过jQuery AJAX post发送JSON到Java/Wicket服务器)

时间:2021-06-19 21:30:20

I'm using jQuery to post JSON to a Java server, but I think my JSON must be wrong. Here's an example of my data and how I'm sending it:

我正在使用jQuery向Java服务器发布JSON,但我认为我的JSON一定是错的。这是我的数据的一个例子,以及我如何发送它:

var lookup = {
    'name': name,
    'description': description,
    'items': [{
        'name': itemName,
        'value': itemValue
    }]
}

$.ajax({
    type: 'post',
    data: lookup,
    dataType: 'json'
});

I'm using Wicket's AbstractAjaxBehavior to receive the data and would like to get a single JSON string that I can parse. When I get a Map of the parameters passed, the keyset looks like this:

我正在使用Wicket的AbstractAjaxBehavior接收数据,并希望获得一个可以解析的JSON字符串。当我得到传递的参数的映射时,keyset看起来是这样的:

items[0][name],
description,
name,
items[0][value],

Obviously I can easily get the values for name and description, but the key for my array of items is messed up. I'm sure it's something simple, but I seem to keep running around the solution. Any suggestions? Thanks!

显然,我可以很容易地获得名称和描述的值,但是我的项目数组的键是混乱的。我相信这很简单,但我似乎一直在寻找解决方案。有什么建议吗?谢谢!

You have to use JSON.stringify:

你必须使用json。stringify:

$.ajax({
    type: 'post',
    data: JSON.stringify(lookup),
    contentType: 'application/json',
    dataType: 'json'
});

You should also specify 'application/json' as the contentType. By default jQuery will serialize objects with application/x-www-form-urlencoded (even if the contentType is application/json'). So you have to do it manually.

您还应该将“application/json”指定为contentType。默认情况下,jQuery将使用application/x-www-form- urlencoding(即使内容类型是application/json)序列化对象。所以你必须手动操作。

EDIT: Key for 'post' should be type, not method.

编辑:“post”的键应该是类型,而不是方法。
