先看一下参数表和参数示例
首先是参数，我们而已发现，json数据成层级方式显示，所以我们先以层级关系为主 定义类(从图中可以发现一共存在6个类)：定义类的时候我们需要把子级类也定义出来（标黄部分）。这里定义的类只是请求参数的类
public class L_Lable { //Lable public L_Data Data { get; set; } public string Requestld { get; set; } public string RequestTime { get; set; } public string Version { get; set; } }public class L_Data { public string OrderID { get; set; } public L_ParcelInformation ParcelInformation { get; set; } public L_RecipientAddress RecipientAddress { get; set; } public string ChannelName { get; set; } public string Token { get; set; } public string ServiceTypeCode { get; set; } public string WarehouseCode { get; set; } public string LabelMarkText { get; set; } public L_RedundancyField RedundancyField { get; set; } }public class L_ParcelInformation { public string Weight { get; set; } public string WeightUnit { get; set; } public string Length { get; set; } public string Width { get; set; } public string Height { get; set; } public string SizeUnit { get; set; } public string ExistDangerousGoods { get; set; } public L_ProductInformations ProductInformations { get; set; } } public class L_RecipientAddress { //L_RecipientAddress public string FirstName { get; set; } public string LastName { get; set; } public string Company { get; set; } public string StreetAddress { get; set; } public string StreetAddress2 { get; set; } public string StreetAddress3 { get; set; } public string City { get; set; } public string State { get; set; } public string ZIPCode { get; set; } public string Country { get; set; } public string PhoneNumber { get; set; } public string PhoneExtension { get; set; } public string Email { get; set; } public string IsResidential { get; set; } } public class L_RedundancyField { public string SignatureOption { get; set; } } public class L_ProductInformations { public string Description { get; set; } public string Quantity { get; set; } public string Weights { get; set; } public string WeightUnits { get; set; } public string Currency { get; set; } public string Value { get; set; } public string Sku { get; set; } public string Remark { get; set; } public string ProductUrl { get; set; } public string HSCode { get; set; } }
类定义完成之后定义一个api控制器:(由于我的数据是从数据库中得到的，所以会有 GetLable(); GetParcelInformation(); GetProductInformations(); GetRecipientAddress(); GetRedundancyField(); GetData(); 方法去查询数据) 查询的方法自行定义
using System;using System.Collections.Generic;using System.Linq;using System.Threading.Tasks;using Microsoft.AspNetCore.Mvc;using Tally_test.Model;using Newtonsoft.Json;using System.Data;using System.Text;using System.Net;using System.IO;namespace Tally_test.Controllers{ [Route("api/[controller]")] [ApiController] public class ValuesController : ControllerBase { private IVLableListService _VLableList { get; set; } public ValuesController(IVLableListService VLableList) { _VLableList = VLableList; } // GET api/values [HttpGet] public ActionResult > Get() { return new string[] { "value1", "value2" }; } // GET api/values/5 [HttpGet("{id}")] public ActionResult Get(int id) { return "value"; } // POST api/values [HttpPost] public void Post([FromBody] string value) { } // PUT api/values/5 [HttpPut("{id}")] public void Put(int id, [FromBody] string value) { } // DELETE api/values/5 [HttpDelete("{id}")] public void Delete(int id) { } //查询标签数据 public async Task GetLable() { try { var x = _VLableList.GetLable(); return await x; } catch (Exception) { throw; } } public async Task GetParcelInformation() { try { var x = _VLableList.GetParcelInformation(); return await x; } catch (Exception) { throw; } } public async Task GetProductInformations() { try { var x = _VLableList.GetProductInformations(); return await x; } catch (Exception) { throw; } } public async Task GetRecipientAddress() { try { var x = _VLableList.GetRecipientAddress(); return await x; } catch (Exception) { throw; } } public async Task GetRedundancyField() { try { var x = _VLableList.GetRedundancyField(); return await x; } catch (Exception) { throw; } } public async Task GetData() { try { var x = _VLableList.GetData(); return await x; } catch (Exception) { throw; } } 控制器的主要内容我另起一标签（标黄部分为给子级类赋值）注意赋值前后顺序
[HttpGet("GetLables")] public string GetLables() { string result = ""; //接收从数据库中查询的数据 var a = GetLable(); var b = GetParcelInformation(); var c = GetProductInformations(); var d = GetRecipientAddress(); var e = GetRedundancyField(); var f = GetData(); //实例化类并进行赋值 L_ProductInformations ProductInformations = new L_ProductInformations(); { ProductInformations.Description = c.Result.Description; ProductInformations.Quantity = c.Result.Quantity; ProductInformations.Weights = c.Result.Weights; ProductInformations.WeightUnits = c.Result.WeightUnits; ProductInformations.Currency = c.Result.Currency; ProductInformations.Value = c.Result.Value; ProductInformations.Sku = c.Result.Sku; ProductInformations.Remark = c.Result.Remark; ProductInformations.ProductUrl = c.Result.ProductUrl; ProductInformations.HSCode = c.Result.HSCode; } L_RecipientAddress RecipientAddress = new L_RecipientAddress(); { RecipientAddress.FirstName = d.Result.FirstName; RecipientAddress.LastName = d.Result.LastName; RecipientAddress.Company = d.Result.Company; RecipientAddress.StreetAddress = d.Result.StreetAddress; RecipientAddress.StreetAddress2 = d.Result.StreetAddress2; RecipientAddress.StreetAddress3 = d.Result.StreetAddress3; RecipientAddress.City = d.Result.City; RecipientAddress.State = d.Result.State; RecipientAddress.ZIPCode = d.Result.ZIPCode; RecipientAddress.Country = d.Result.Country; RecipientAddress.PhoneNumber = d.Result.PhoneNumber; RecipientAddress.PhoneExtension = d.Result.PhoneExtension; RecipientAddress.Email = d.Result.Email; RecipientAddress.IsResidential = d.Result.IsResidential; } L_RedundancyField RedundancyField = new L_RedundancyField(); { RedundancyField.SignatureOption = e.Result.SignatureOption; } L_ParcelInformation ParcelInformation = new L_ParcelInformation(); { ParcelInformation.Weight = b.Result.Weight; ParcelInformation.WeightUnit = b.Result.WeightUnit; ParcelInformation.Length = b.Result.Length; ParcelInformation.Width = b.Result.Width; ParcelInformation.Height = b.Result.Height; ParcelInformation.SizeUnit = b.Result.SizeUnit; ParcelInformation.ExistDangerousGoods = b.Result.ExistDangerousGoods; ParcelInformation.ProductInformations = ProductInformations; } L_Data datas = new L_Data(); { datas.OrderID = f.Result.OrderID; datas.ChannelName = f.Result.ChannelName; datas.Token = f.Result.Token; datas.ServiceTypeCode = f.Result.ServiceTypeCode; datas.WarehouseCode = f.Result.WarehouseCode; datas.LabelMarkText = f.Result.LabelMarkText; datas.OrderID = f.Result.OrderID; datas.ParcelInformation = ParcelInformation; datas.RecipientAddress = RecipientAddress; datas.RedundancyField = RedundancyField; } V_LableList LableList = new V_LableList(); { LableList.Requestld = a.Result.Requestld; LableList.RequestTime = a.Result.RequestTime; LableList.Version = a.Result.Version; LableList.Data = datas; } //类实例化并赋值之后进行 json序列化 （LableList是父类，所以我们最后只要实例化父类就可以了） string Datajson = JsonConvert.SerializeObject(LableList); //HttpWebRepuest接收 string URL = "https://.../Api/LabelPrintService/PrintLabel";//你需要调用的接口路径 Encoding dataEncode = Encoding.UTF8;//编码格式 result = OpenReadWithHttps(URL, Datajson, dataEncode); return result; } //方法为了方便我就写在了控制器里，尽量放到类里面 public string OpenReadWithHttps(string URL, string paramData, Encoding dataEncode) { string responseContent = string.Empty; try { byte[] byteArray = dataEncode.GetBytes(paramData); //转化 HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(new Uri(URL)); webReq.Method = "POST"; webReq.ContentType = "application/json"; webReq.ContentLength = byteArray.Length; //webReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes())); using (Stream reqStream = webReq.GetRequestStream()) { reqStream.Write(byteArray, 0, byteArray.Length);//写入参数 } ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true; HttpWebResponse response = (HttpWebResponse)webReq.GetResponse(); using (StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.Default)) { /*这里面写你需要进行的操作*/ /* responseContent = sr.ReadToEnd().ToString(); string a = GetJsonValue(responseContent); //主要进行byte[]类型转换的 L_Data data = JsonConvert.DeserializeObject (a); System.IO.File.WriteAllBytes(@"D:\61290983244643354835.jpg", data.LabelImage); */ } } catch (Exception ex) { return ex.Message; } return responseContent;} public static string GetJsonValue(string strJson) { string strResult; JObject jo = JObject.Parse(strJson); string[] values = jo.Properties().Select(item => item.Value.ToString()).ToArray(); if (values == null) { strResult = ""; } else { strResult = values[0]; } return strResult; } }}
现在我们来看一下文档中的返回参数和效果
再来看一下我们的运行效果
这个接口的主要作用是打印标签，上面数据中的“LableImage”属性的值是byte[]类型，需要我们自行处理为图片类型就好了
以上仅为个人操作所得，有误之处，敬请之出，谢谢。
