javascript - 如何在mvc4中将多个参数从 View 发送到api Controller

Question

我有多个参数必须传递给 api Controller 。

我做的是

在我的 javascript 中

            var routeInfo = JSON.stringify(routes);
            var colors = JSON.stringify(colorsArray);
            var times = JSON.stringify(mytimeArray);
            var distances = JSON.stringify(myDistancArray);
            var dir = $("#Direction").val();

          var fullString = routeInfo + ";" + colors + ";" + times + ";" + distances+";"+dir;

            $.post("api/HomeToSchool/?route=" + fullString,
                function (data) {
                    if (data = true) {
                        alert("Routes Saved Successfully");
                    }
                    else if (data = false) {
                        alert("Routes are not saved");
                    }
                });

& 在我的 Controller 中

public bool PostHomeToSchoolRoutes([FromUri]string route)
        {
// my logic
}

这里我只是获取“routeInfo”的值，其他值没有出现。例如

var routeInfo =  [["Børge,Brogade  38, 4100, Ringsted,09:25:00,55.43953, 11.79043","Grete,Sjællandsgade  27, 4100, Ringsted,09:25:00,55.44024, 11.78852","Else,Fynsgade  14, 4100, Ringsted,09:25:00,55.44128, 11.78595","Birthe,Eksercerpladsen  47, 4100, Ringsted,09:25:00,55.44954, 11.80309","Knud Lavard Centret, Eksercerpladsen 3,  4100,  Ringsted,370,55.45014, 11.80474"]]

                var colors = ["#886A52"]
                var times =  [7.97]
                var distances = [3.36]
                var dir = 0

我在 Controller 中得到的是

[["Børge,Brogade  38, 4100, Ringsted,09:25:00,55.43953, 11.79043","Grete,Sjællandsgade  27, 4100, Ringsted,09:25:00,55.44024, 11.78852","Else,Fynsgade  14, 4100, Ringsted,09:25:00,55.44128, 11.78595","Birthe,Eksercerpladsen  47, 4100, Ringsted,09:25:00,55.44954, 11.80309","Knud Lavard Centret, Eksercerpladsen 3,  4100,  Ringsted,370,55.45014, 11.80474"]];["

其他值不会出现。我在这里做错了什么。

我担心你的 url 太长(>255 个字符)，你可以试试这个。

$.ajax({
     type: 'POST',
     url:"api/HomeToSchool",
     data:{routeInfo:routes,colors:colorsArray,times:mytimeArray,distances:myDistancArray,dir:dir},
     dataType: "json",
     traditional:true,
     function (data) {
                        if (data = true) {
                            alert("Routes Saved Successfully");
                        }
                        else if (data = false) {
                            alert("Routes are not saved");
                        }
                    }
});

和你的 Controller :

public bool PostHomeToSchoolRoutes(string[] routeInfo,string[] colors,double[] times,double[] distances,int dir)
        {
// my logic
}

我看到您正在为 routeInfo 使用二维数组。但是只有一项，我觉得你应该把它改成一维数组来兼容 Controller 代码 string[] routeInfo
