我得到了“400（错误请求）”的结果，我的请求有问题吗？还是我应该将我的请求分成几个请求？

ids 包含带有分号分隔符的 id 列表。

Answer 1

如果您的查询字符串超出maxQueryStringLengthASP.NET 将返回一个400 (Bad Request)状态。

此设置默认为 2048，您可以增加它，但是，浏览器也限制查询字符串/url 长度，例如 IE9最多允许 2083 个字符。

如果您可以更改代码，而不是使用$.getJSON长查询字符串，我将通过使用以下请求POST的请求发送数据：$.postdataType: json

$.post(yourUrl, yourData, function (data) {
     // data has the same value as if you used $.getJSON
}, 'json');
