如何将json对象数组发布到web api

Question

如何将JSON数组发布到Web API？它适用于单个对象.

这是我试过的,但控制器似乎正在返回0而不是预期3.

这是我的JSON:

var sc = [{
              "ID": "5",
              "Patient_ID": "271655b8-c64d-4061-86fc-0d990935316a",
              "Table_ID": "Allergy_Trns",
              "Checksum": "-475090533",
              "LastModified": "2015-01-22T20:08:52.013"
          },
          {
              "ID": "5",
              "Patient_ID": "271655b8-c64d-4061-86fc-0d990935316a",
              "Table_ID": "Allergy_Trns",
              "Checksum": "-475090533",
              "LastModified": "2015-01-22T20:08:52.013"
          },
          {
              "ID": "5",
              "Patient_ID": "271655b8-c64d-4061-86fc-0d990935316a",
              "Table_ID": "Allergy_Trns",
              "Checksum": "-475090533",
              "LastModified": "2015-01-22T20:08:52.013"
          }];           

AJAX电话:

$.ajax({
           url: urlString,
           type: 'POST',
           data: sc,
           dataType: 'json',
           crossDomain: true,
           cache: false,
           success: function (data) { console.log(data); }
        });

Web API控制器:

[HttpPost]
public string PostProducts([FromBody]List<SyncingControl> persons)
{
    return persons.Count.ToString(); // 0, expected 3
}

Answer 1

Table_ID": "Allergy_Trns"应该是json中有错误"Table_ID": "Allergy_Trns".

缺少双引号.

更新

您需要确保将参数发送为json,如下所示:

 $.ajax({
        url: urlString,
        type: 'POST',
        data: JSON.stringify(sc),
        dataType: 'json',
        contentType: 'application/json',
        crossDomain: true,
        cache: false,
        success: function (data) { console.log(data); }
    });

注意JSON.stringify(sc),@herbi在指定内容类型方面也是部分正确的.
