.getJSONを使用してASP.Net MVC 3 jsonメソッドを呼び出そうとしたときに不正な要求を取得します。

Question

jQuery 1.7を使用しているクライアントがASP.Net MVC 3 Jsonメソッドを使用してサーバーにリクエストを行います。私は以下のように私の要求の打撃を与えるだろう。

と、私は「400（不正な要求）」との結果を得た、私の要求に何か問題があるGET？または私の要求をいくつかの要求に分割する必要がありますか？

idsにはセミコロン区切り記号付きのIDのリストが含まれていました。

Answer 1

クエリ文字列がmaxQueryStringLengthを超える場合、ASP.NETは400 (Bad Request)ステータスを返します。

この設定の既定値は2048ですが、ブラウザでもクエリ文字列/ URLの長さが制限されます。たとえばIE9の場合はmaximum of 2083 charactersとなります。

あなたが代わりに私がdataType: jsonと$.postを使用してPOST要求を介してデータを送信し、長いクエリ文字列で$.getJSONを使用してのコードを、変更することができる場合：

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