我正在使用instagram紅寶石寶石。如果我做了超過2個以下的請求是我得到的錯誤。現在Ruby on rails：JSON :: ParserError和500內部服務器錯誤與instagram
，前兩個請求時，它顯示了這個
Processing by HomesController#index as JS
Processing by HomesController#index as */*
因此，當第三個請求現在會發生，它誤差修改成（如上面說的）這個
Completed 500 Internal Server Error in 4525ms
JSON::ParserError (757: unexpected token at '<!DOCTYPE html>

我認爲什麼是錯的頭部？由於我正在通過ajax進行這個過程，我如何強制它通過JS來處理它？因爲這是我認爲在這裏似乎有用的東西。
這裏是我的Ajax代碼
{
$.ajax({
url: /home,
method: "post",
data: {
// data goes here
},
success: function(html)
{
if(html)
{
// html goes here
}else
{
// html goes here</center>');
}
}
否在這種情況下，它會'阻止呼叫' – psharma
