【问题描述】：

我正在尝试使用Trustpilot API 发布产品评论邀请。

正如您在下面的代码中看到的那样，我已成功完成身份验证步骤，但是我无法成功将数据发布到Trustpilot Invitations API。 PostAsnyc 方法似乎卡在 WaitingForActivation 状态。我想知道您是否有什么可以提供帮助的建议。

这是我的代码（这里的 API 凭据不是真实的！）：

using (HttpClient httpClient = new HttpClient())

    string trustPilotAccessTokenUrl = "https://api.trustpilot.com/v1/oauth/oauth-business-users-for-applications/accesstoken";

    httpClient.BaseAddress = new Uri(trustPilotAccessTokenUrl);

    httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));

    var authString = "MyApiKey:MyApiSecret";

    httpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Base64Encode(authString));

    var stringPayload = "grant_type=password&username=MyUserEmail&password=MyPassword";

    var httpContent = new StringContent(stringPayload, Encoding.UTF8, "application/x-www-form-urlencoded");

    HttpResponseMessage httpResponseMessage = httpClient.PostAsync(trustPilotAccessTokenUrl, httpContent).Result;

    var accessTokenResponseString = httpResponseMessage.Content.ReadAsStringAsync().Result;

    var accessTokenResponseObject = JsonConvert.DeserializeObject<AccessTokenResponse>(accessTokenResponseString);

    // Create invitation object
    var invitation = new ReviewInvitation
    
        ReferenceID = "inv001",
        RecipientName = "Jon Doe",
        RecipientEmail = "[e-mail]",
        Locale = "en-US"
    ;

    var jsonInvitation = JsonConvert.SerializeObject(invitation);

    var client = new HttpClient();
    client.DefaultRequestHeaders.Add("token", accessTokenResponseObject.AccessToken);

    var invitationsUri = new Uri("https://invitations-api.trustpilot.com/v1/private/business-units/MyBusinessID/invitations");

    // This here as a status of WaitingForActivation!
    var a = client.PostAsync(invitationsUri, new StringContent(jsonInvitation)).ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode());

【参考方案1】：

这就是我解决问题的方法：

    // Serialize our concrete class into a JSON String
    var jsonInvitation = JsonConvert.SerializeObject(invitationObject);

    // Wrap our JSON inside a StringContent which then can be used by the HttpClient class
    var stringContent = new StringContent(jsonInvitation);


    // Get the access token
    var token = GetAccessToken().AccessToken;

    // Create a Uri 
    var postUri = new Uri("https://invitations-api.trustpilot.com/v1/private/business-units/BusinessUnitID/invitations");


    // Set up the request
    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, postUri);
    request.Content = stringContent;
    request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
    request.Content.Headers.Add("token", token);

     // Set up the HttpClient
    var httpClient = new HttpClient();
    //httpClient.DefaultRequestHeaders.Accept.Clear();
    //httpClient.BaseAddress = postUri;
    //httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
    //httpClient.DefaultRequestHeaders.AcceptLanguage.Add(new StringWithQualityHeaderValue("en-US"));

    var task = httpClient.SendAsync(request);

    task.Wait();
