Try changing the contentTypeto application/x-www-form-urlencodedor just dropping it since it is the default value.
尝试更改contentType为application/x-www-form-urlencoded或只是删除它，因为它是默认值。

Your problem is that the data you are posting is not matching the content-typeyou are sending.
您的问题是您发布的数据与content-type您发送的数据不匹配。
contentTypeis for the data being sent to the server, and dataTypeis for the data being received from the server.
contentType用于发送到服务器dataType的数据，用于从服务器接收的数据。
Just remove the contentType: "application/json"from your code.
只需contentType: "application/json"从您的代码中删除。
