我的AJAX代码在这里

function demo(data) {
    debugger

    var treeBinding =arrayToObjectString(data) 

    $.ajax({
        url: '/Flow/demo',
        type: "GET",
        data: { dd: treeBinding },
        success: function (res) {

        },
        error: function (error) {
            //alert('error : ' + json.stringify(error));
        }
    });
}

当我尝试仅发布此数据样本时，我收到404错误。请告诉我一些解决方案。

Answer 1

尝试发送：

JSON.stringify（yourData）

Answer 2

检查ajax中的url是否与后面的代码相同。这是导致404错误的一个主要原因。

Answer 3

使用contentType: "application/json;charset=utf-8"和data:treeBinding，如下所示。希望这能解决你的问题。

function demo(data) {
    var treeBinding =arrayToObjectString(data) 

    $.ajax({
        url: '/Flow/demo',
        type: "GET",
        data: treeBinding,
        contentType: "application/json;charset=utf-8"
        success: function (res) {

        },
        error: function (error) {
            //alert('error : ' + json.stringify(error));
        }
    });
}

无法在Controller上发送Json数据
