传递httpPost中的对象数组

本文关键字：对象 数组 httpPost 传递 | 更新日期: 2023-09-27 17:59:04

我开发了一个web api。我需要传递一组对象

[{"Id":"10010","lati":"12.991845763535506","longi":"77.54596710205078","PSID":"1001"},
 {"Id":"10011","lati":"12.97846402705198","longi":"77.55729675292969","PSID":"1001"},
 {"Id":"10012","lati":"12.967758119178907","longi":"77.54425048828125","PSID":"1001"}]

web api的模型类在下面给出

Locate.cs

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;
namespace webapi.Models
{
    public class Locate
    {
       [Key][Required]
       public string Id { get; set; }
       public string lati { get; set; }
       public string longi { get; set; }
       public string PSID { get; set; }
     }
 }

控制器文件中与post方法对应的代码在下面给出

LocatesController.cs

  // POST: api/Locates
    [ResponseType(typeof(Locate))]
    public async Task<IHttpActionResult> PostLocate(Locate locate)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }
        db.Locates.Add(locate);
        try
        {
            await db.SaveChangesAsync();
        }
        catch (DbUpdateException)
        {
          if (LocateExists(locate.Id))
            {
                return Conflict();
            }
            else
            {
                throw;
            }
        }
        return CreatedAtRoute("DefaultApi", new { id = locate.Id }, locate);
    }
    private bool LocateExists(string id)
    {
        return db.Locates.Count(e => e.Id == id) > 0;
    }

我在下面给出的js脚本中发送http post请求

app.js

  $scope.adding = function()
  {    
    var idd = $rootScope.vaar;
    var datas = [];
    var len = latitudes.length;
    for (var i = 0; i < len; i++) {
        datas.push({
            "Id": idd + i.toString(),
            "lati": latitudes[i].toString(),
            "longi": longitudes[i].toString(),
            "PSID": idd
        });
    }
 var jsonData = angular.Json(datas);
  var objectToSerialize = {'object':jsonData};
  var data = $.param(objectToSerialize);
   var config = {
        headers: {
            'Content-Type': 'application/-www-form-urlencoded;charset=utf-8'
        }
    }
    $http.post('http://localhost:8080/pool/api/locates/', data,config).success(function (data, status, headers, config) {
        alert("Success");
            }).error(function (data, status, header, config) {
            alert("An error has occured while adding!"+status);
             });
        }

它不添加上面的数组。请帮助我

传递httpPost中的对象数组

问题就在这里：

[ResponseType(typeof(Locate))]
public async Task<IHttpActionResult> PostLocate(Locate locate)

并且你发布了一个数组，所以它应该是：

[ResponseType(typeof(Locate))]
public async Task<IHttpActionResult> PostLocate(List<Locate> locates)

问题解决了。我将参数更改为(List<Locate> locates)，并在post方法中创建了一个逻辑。感谢Glenn Packer
