一、appsettings.json定义小程序配置信息
"WX": { "AppId": "wx88822730803edd44", "AppSecret": "75b269042e8b5026e6ed14aa24ba9353", "Templates": { "Audit": { "TemplateId": "aBaIjTsPBluYtj2tzotzpowsDDBGLhXQkwrScupnQsM", "PageUrl": "/pages/index/formAudit?formId={0}&tableId={1}", "MiniprogramState": "developer", "Lang": "zh_TW", "Data": { "Title": "thing6", "Content": "thing19", "Date": "date9" } } }, "SignatureToken": "aaaaaa", "MessageSendUrl": "https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token={0}", "AccessTokenUrl": "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={0}&secret={1}" }
二、编写通用类加载配置
using System; using System.Text; using System.Security.Cryptography; using Microsoft.Extensions.Configuration; using Microsoft.Extensions.Configuration.Json; namespace WXERP.Services { /// <summary> /// 项目公有静态类 /// </summary> public class Common { /// <summary> /// 獲取根目錄 /// </summary> public static string AppRoot => Environment.CurrentDirectory;// AppContext.BaseDirectory; /// <summary> /// 獲取項目配置 /// </summary> public static IConfiguration Configuration { get; set; } /// <summary> /// 加載項目配置 /// </summary> static Common() { Configuration = new ConfigurationBuilder() .Add(new JsonConfigurationSource { Path = "appsettings.json", ReloadOnChange = true //当appsettings.json被修改时重新加载 }) .Build(); } /// <summary> /// SHA1加密 /// </summary> /// <param>需要加密的字符串</param> /// <returns>返回40位大寫字符串</returns> public static string SHA1(string content) { try { SHA1 sha1 = new SHA1CryptoServiceProvider(); byte[] bytes_in = Encoding.UTF8.GetBytes(content); byte[] bytes_out = sha1.ComputeHash(bytes_in); sha1.Dispose(); string result = BitConverter.ToString(bytes_out); result = result.Replace("-", ""); return result; } catch (Exception ex) { throw new Exception("Error in SHA1: " + ex.Message); } } } }
三、编写HttpHelper请求类
using System; using System.Text; using System.Net.Http; using System.Net.Http.Headers; using System.Threading.Tasks; using System.Collections.Generic; namespace WXERP.Services { /// <summary> /// HTTP請求輔助類 /// </summary> public class HttpHelper { /// <summary> /// post同步請求 /// </summary> /// <param>地址</param> /// <param>數據</param> /// <param>application/xml、application/json、application/text、application/x-www-form-urlencoded</param> /// <param>請求頭</param> /// <returns></returns> public static string HttpPost(string url, string postData = null, string contentType = null, Dictionary<string, string> headers = null) { using HttpClient client = new HttpClient(); if (headers != null) { foreach (var header in headers) client.DefaultRequestHeaders.Add(header.Key, header.Value); } postData ??= ""; using HttpContent httpContent = new StringContent(postData, Encoding.UTF8); if (contentType != null) httpContent.Headers.ContentType = new MediaTypeHeaderValue(contentType); HttpResponseMessage response = client.PostAsync(url, httpContent).Result; return response.Content.ReadAsStringAsync().Result; } /// <summary> /// post異步請求 /// </summary> /// <param>地址</param> /// <param>數據</param> /// <param>application/xml、application/json、application/text、application/x-www-form-urlencoded</param> /// <param>請求超時時間</param> /// <param>請求頭</param> /// <returns></returns> public static async Task<string> HttpPostAsync(string url, string postData = null, string contentType = null, int timeOut = 30, Dictionary<string, string> headers = null) { using HttpClient client = new HttpClient(); client.Timeout = new TimeSpan(0, 0, timeOut); if (headers != null) { foreach (var header in headers) client.DefaultRequestHeaders.Add(header.Key, header.Value); } postData ??= ""; using HttpContent httpContent = new StringContent(postData, Encoding.UTF8); if (contentType != null) httpContent.Headers.ContentType = new MediaTypeHeaderValue(contentType); HttpResponseMessage response = await client.PostAsync(url, httpContent); return await response.Content.ReadAsStringAsync(); } /// <summary> /// get同步請求 /// </summary> /// <param>地址</param> /// <param>請求頭</param> /// <returns></returns> public static string HttpGet(string url, Dictionary<string, string> headers = null) { using HttpClient client = new HttpClient(); if (headers != null) { foreach (var header in headers) client.DefaultRequestHeaders.Add(header.Key, header.Value); } HttpResponseMessage response = client.GetAsync(url).Result; return response.Content.ReadAsStringAsync().Result; } /// <summary> /// get異步請求 /// </summary> /// <param></param> /// <param></param> /// <returns></returns> public static async Task<string> HttpGetAsync(string url, Dictionary<string, string> headers = null) { using HttpClient client = new HttpClient(); if (headers != null) { foreach (var header in headers) client.DefaultRequestHeaders.Add(header.Key, header.Value); } HttpResponseMessage response = await client.GetAsync(url); return await response.Content.ReadAsStringAsync(); } } }
四、在sqlserver下存储并获取openid，这个主要是因为提交消息并不是在微信小程序端，如果是在微信小程序上发起订阅消息，可以忽略这个步骤
