将 JSON 对象发送到 Web API

问题描述

我想弄清楚如何将一些信息从表单发送到 Web API 操作.这是我尝试使用的 jQuery/AJAX:

var source = {'ID': 0,'ProductID': $('#ID').val(),'PartNumber': $('#part-number').val(),'供应商ID':$('#Vendors').val()}$.ajax({类型:POST"，数据类型:json"，url: "/api/PartSourceAPI/",数据:JSON.stringify({模型:源})，成功:功能(数据){alert('成功');},错误:函数(错误){jsonValue = jQuery.parseJSON(error.responseText);jError('保存新零件源时出错:' + jsonValue, { TimeShown: 3000 });}});

这是我的模型

公共类 PartSourceModel{公共 int ID { 获取；放;}公共 int ProductID { 获取；放;}公共 int VendorID { 获取；放;}公共字符串 PartNumber { 获取；放;}}

这是我的观点

@foreach(Model.Sources 中的 SmallHorse.ProductSource 源代码){@source.ItemNumber 
}
<label>部件号</label><input type="text" id="part-number" name="part-number"/><input type="submit" id="save-source" name="save-source" value="Add"/>

这是我的控制器动作

//POST api/partsourceapipublic void Post(PartSourceModel 模型){//当前没有值被传递到模型参数}

我错过了什么?现在，当我在 ajax 请求命中控制器操作时调试并逐步执行此操作时，没有任何内容被传递到模型参数中.

解决方案

试试这个:

jquery

 $('#save-source').click(function (e) {e.preventDefault();变量源 = {'ID': 0,//'ProductID': $('#ID').val(),'PartNumber': $('#part-number').val(),//'VendorID': $('#Vendors').val()}$.ajax({类型:POST"，数据类型:json"，url: "/api/PartSourceAPI",数据源，成功:功能(数据){警报(数据)；},错误:函数(错误){jsonValue = jQuery.parseJSON(error.responseText);//jError('保存新部分源时出错:' + jsonValue, { TimeShown: 3000 });}});});

控制器

 public string Post(PartSourceModel 模型){返回模型.零件编号；}

查看

部件号<input type="text" id="part-number" name="part-number"/><input type="submit" id="save-source" name="save-source" value="Add"/>

现在，当您在填写完文本框后单击Add"时，controller 会吐出您在PartNumber 警报框.

I am trying to figure out how I can send some information from a form to a Web API action. This is the jQuery/AJAX I'm trying to use:

var source = {
        'ID': 0,
        'ProductID': $('#ID').val(),
        'PartNumber': $('#part-number').val(),
        'VendorID': $('#Vendors').val()
    }

    $.ajax({
        type: "POST",
        dataType: "json",
        url: "/api/PartSourceAPI/",
        data: JSON.stringify({ model: source }),
        success: function (data) {
            alert('success');
        },
        error: function (error) {
            jsonValue = jQuery.parseJSON(error.responseText);
            jError('An error has occurred while saving the new part source: ' + jsonValue, { TimeShown: 3000 });
        }
    });

Here is my model

public class PartSourceModel
{
    public int ID { get; set; }
    public int ProductID { get; set; }
    public int VendorID { get; set; }
    public string PartNumber { get; set; }
}

Here is my view

<div id="part-sources">
    @foreach (SmallHorse.ProductSource source in Model.Sources)
    {
        @source.ItemNumber <br />
    }
</div>
<label>Part Number</label>
<input type="text" id="part-number" name="part-number" />

<input type="submit" id="save-source" name="save-source" value="Add" />

Here is my controller action

// POST api/partsourceapi
public void Post(PartSourceModel model)
{
    // currently no values are being passed into model param
}

What am I missing? right now when I debug and step through this when the ajax request hits the controller action there is nothing being passed into the model param.

解决方案

Try this:

jquery

    $('#save-source').click(function (e) {
        e.preventDefault();
        var source = {
            'ID': 0,
            //'ProductID': $('#ID').val(),
            'PartNumber': $('#part-number').val(),
            //'VendorID': $('#Vendors').val()
        }
        $.ajax({
            type: "POST",
            dataType: "json",
            url: "/api/PartSourceAPI",
            data: source,
            success: function (data) {
                alert(data);
            },
            error: function (error) {
                jsonValue = jQuery.parseJSON(error.responseText);
                //jError('An error has occurred while saving the new part source: ' + jsonValue, { TimeShown: 3000 });
            }
        });
    });

Controller

    public string Post(PartSourceModel model)
    {
        return model.PartNumber;
    }

View

<label>Part Number</label>
<input type="text" id="part-number" name="part-number" />

<input type="submit" id="save-source" name="save-source" value="Add" />

Now when you click 'Add' after you fill out the text box, the controller will spit back out what you wrote in the PartNumber box in an alert.
