ASP.NET：Ajax不发送字符串
-
确保使用的是POST方法
function sendData(strData) { $.ajax({ type: "POST", url: "MyApiUrl", data: strData, contentType: "application/json; charset=utf-8", dataType: "json", success: function (response) { console.log(response); }, error: function (xhr, ajaxOptions, thrownError) { console.log(xhr.status); console.log(thrownError); } }); }
-
设置content-type为application/json，并将data参数转换为JSON字符串
function sendData(strData) { $.ajax({ type: "POST", url: "MyApiUrl", data: JSON.stringify(strData), contentType: "application/json; charset=utf-8", dataType: "json", success: function (response) { console.log(response); }, error: function (xhr, ajaxOptions, thrownError) { console.log(xhr.status); console.log(thrownError); } }); }
-
如果仍然无法发送字符串，请尝试使用XMLHttpRequest对象手动发送
function sendData(strData) { var xhr = new XMLHttpRequest(); xhr.open('POST', 'MyApiUrl', true); xhr.setRequestHeader('Content-Type', 'application/json'); xhr.onreadystatechange = function () { if (xhr.readyState == 4 && xhr.status == 200) { console.log(xhr.responseText); } }; xhr.send(strData); }
