我想从 jQuery 向远程服务器发出 POST 请求。当我写这样的代码时
$.ajax({
type: 'POST',
url: 'http://mysite:8080/orderService/order/send',
crossDomain: true,
data: JSON.stringify(orderSendRequest),
dataType: 'json',
success: function(responseData, textStatus, jqXHR) {
var value = responseData.someKey;
},
error: function (responseData, textStatus, errorThrown) {
alert('POST failed.');
}
});
一切正常,但我希望 ContextType 为 application/json,当我将此行添加到代码中时,请求不起作用,并且出现以下错误:
XMLHttpRequest cannot load http://mysite:8080/orderService/order/send. Origin null is not allowed by Access-Control-Allow-Origin.
$.ajax({
type: 'POST',
url: 'http://mysite:8080/orderService/order/send',
crossDomain: true,
data: JSON.stringify(orderSendRequest),
dataType: 'json',
contentType : 'application/json; charset=utf-8',
success: function(responseData, textStatus, jqXHR) {
var value = responseData.someKey;
},
error: function (responseData, textStatus, errorThrown) {
alert('POST failed.');
}
});
