嘿，伙计们，我在使用 ajax PUT 时遇到了一个愚蠢的问题，在我尝试将 json 数据放回之后，即使我使用了：dataType：“application/json”，服务器也会认为它的 xml 数据，知道为什么会发生这种情况吗？这就是我的 PUT 的样子：
$.ajax({
type: "PUT",
url: bank_url,
dataType: "application/json",
data: {"banking_detail_id": page.viewModel.payer_banking_detail_id(),
"person_id": person_id, "account_number": page.viewModel.payer_account_number(),
"branch": page.viewModel.payer_branch(), "date_inserted": page.viewModel.payer_date_insterted(),
"date_effective": page.viewModel.payer_date_effective(), "account_type": page.viewModel.payer_account_type(),
"account_holder": page.viewModel.payer_account_holder() , "debit_day": page.viewModel.payer_debit_day() ,
"branch_code": page.viewModel.payer_branch_code() , "bank_branch_id": page.viewModel.payer_bank_branch_id(),
"branch_name": page.viewModel.payer_branch_name(), "bank_name": page.viewModel.payer_bank_name(),
"user_id": page.viewModel.payer_user_id()},
});
服务器响应如下：
