泛微OA调用发送消息接口 .Net C#示例

详细步骤查看上面两个文档

泛微OA发送消息，只有java代码示例，这里整理了一套.Net版本的示例，仅供参考，目前写的可以调用，后期泛微接口做调整，本文章不做对应更新。

用的.Net Core 3.1框架，需要先依赖注入

cs 复制代码

private readonly string _appid = string.Empty;
private readonly string _ip = string.Empty;
private readonly string _cpk = string.Empty;
private readonly int _time = 1800;
private readonly string _code = string.Empty;
private readonly IRepository<Message, string> _messageRepository;
private readonly IRepository<MessageDetail, string> _messageDetailRepository;
private readonly IGuidGenerator _guidGenerator;
private readonly IObjectMapper _objectMapper;
private readonly MesMessageDbContext _mesMessageDbContext;
private readonly ILogger<MessageDetailService> _logger;
private readonly IHttpClientFactory _httpClientFactory;
private readonly IConfiguration _configuration;
private readonly IRepository<Appsetting, Guid> _appsettingRepository;

public MessageDetailService(
    IRepository<Message, string> messageRepository,
    IRepository<MessageDetail, string> messageDetailRepository,
    IGuidGenerator guidGenerator,
    IObjectMapper objectMapper,
    MesMessageDbContext mesMessageDbContext,
    ILogger<MessageDetailService> logger,
    IHttpClientFactory httpClientFactory,
    IConfiguration configuration,
    IRepository<Appsetting, Guid> appsettingRepository)
{
    _messageRepository = messageRepository;
    _messageDetailRepository = messageDetailRepository;
    _guidGenerator = guidGenerator;
    _objectMapper = objectMapper;
    _mesMessageDbContext = mesMessageDbContext;
    _logger = logger;
    _httpClientFactory = httpClientFactory;
    _configuration = configuration;
    _appid = configuration["OA:appid"];
    _ip = configuration["OA:ip"];
    _cpk = configuration["OA:cpk"];
    _time = Convert.ToInt32(configuration["OA:time"]);
    _code = configuration["OA:code"];
    _appsettingRepository = appsettingRepository;
}

第一步获取spk

这里把spk和secret存到了数据库中

cs 复制代码

#region 第一步 获取spk
[UnitOfWork(true)]
private async Task<Result> GetSPKAsync()
{
    var path = "/api/ec/dev/auth/regist";
    Dictionary<string, string> headers = new Dictionary<string, string>();
    headers.Add("appid", _appid);
    headers.Add("cpk", _cpk);

    var resultMsg = await PostAsync(_ip + path, "", "", headers);
    var result = JsonConvert.DeserializeObject<Result>(resultMsg);
    if (result != null && result.status)
    {
        await _appsettingRepository.DeleteAsync(d => d.Code == "spk" || d.Code == "secret");
        AppsettingDto spkInDto = new AppsettingDto()
        {
            Code = "spk",
            Value = result.spk,
            CreateTime = DateTime.Now
        };
        var spkItem = _objectMapper.Map<AppsettingDto, Appsetting>(spkInDto);
        await _appsettingRepository.InsertAsync(spkItem);

        AppsettingDto secretInDto = new AppsettingDto()
        {
            Code = "secret",
            Value = result.secret,
            CreateTime = DateTime.Now
        };
        var secretItem = _objectMapper.Map<AppsettingDto, Appsetting>(secretInDto);
        await _appsettingRepository.InsertAsync(secretItem);
    }
    return result;
}
#endregion

第二步获取token

cs 复制代码

#region 第二步 获取token
/// <summary>
/// 获取token
/// </summary>
/// <returns></returns>
public async Task<string> GetTokenAsync()
{
    var path = "/api/ec/dev/auth/applytoken";
    var spkValue = _appsettingRepository.FirstOrDefault(d => d.Code == "spk")?.Value;
    var secretValue = _appsettingRepository.FirstOrDefault(d => d.Code == "secret")?.Value;
    if (string.IsNullOrWhiteSpace(spkValue) || string.IsNullOrWhiteSpace(secretValue))
    {
        var spkResult = await GetSPKAsync();
        spkValue = spkResult.spk;
        secretValue = spkResult.secret;
    }
    var secret = RsaEncrypt(secretValue, spkValue);
    Dictionary<string, string> headers = new Dictionary<string, string>();
    headers.Add("appid", _appid);
    headers.Add("time", _time.ToString());
    headers.Add("secret", secret);

    var resultMsg = await PostAsync(_ip + path, "", "", headers);
    var result = JsonConvert.DeserializeObject<Result>(resultMsg);

    return await Task.FromResult(result.token);
}
#endregion

第三步调用泛微接口发送消息

cs 复制代码

#region 第三步 调用泛微接口发送消息
public async Task<Result> SendMessageAsync(Content content)
{
    var path = "/api/ec/dev/message/sendCustomMessageSingle";
    var token = await GetTokenAsync();
    Dictionary<string, string> headers = new Dictionary<string, string>();
    headers.Add("token", token);
    headers.Add("appid", _appid);
    //headers.Add("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");
    headers.Add("skipsession", "1");

    //var parameter = JsonConvert.SerializeObject(content);
    Dictionary<string, string> data = new Dictionary<string, string>();
    data.Add(nameof(content.code), content.code);
    data.Add(nameof(content.userIdList), content.userIdList);
    data.Add(nameof(content.creater), content.creater);
    data.Add(nameof(content.title), content.title);
    data.Add(nameof(content.context), content.context);
    var resultMsg = await Post2Async(_ip + path, data,"", headers);

    //var data = $"code={content.code}&userIdList={content.userIdList}&creater={content.creater}&title={content.title}&context={content.context}";
