使用 .Net HttpClient() 创建 Calendly webhook 订阅时出错

Question

我正在尝试使用 .net HttpClient() 为 Calendly 创建 webhook 订阅

https://developer.calendly.com/docs/webhook-subscriptions

我正在尝试将此 Curl 命令转换为 .Net

curl --header "X-TOKEN: <your_token>" --data "url=https://blah.foo/bar&events[]=invitee.created&events[]=invitee.canceled" https://calendly.com/api/v1/hooks

这是我的 .Net 代码：

private static async Task<HttpResponseMessage> PostCreateWebhookSubscription()
{
    var client = new HttpClient {BaseAddress = new Uri("https://calendly.com")};
    var request = new HttpRequestMessage(HttpMethod.Post, "/api/v1/hooks/");
    var keyValues = new List<KeyValuePair<string, string>>
    {
        new KeyValuePair<string, string>("url",
            "https://requestb.in/17ruxqh1&events[]=invitee.created&events[]=invitee.canceled")
    };
    request.Content = new FormUrlEncodedContent(keyValues);
    request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/x-www-form-urlencoded") {CharSet = "UTF-8"};
    request.Content.Headers.Add("X-TOKEN", "<my_calendly_token>");
    return await client.SendAsync(request);
}

我收到此错误 422 错误，但无法弄清楚要更改什么才能使其正常工作。

收到无法处理的实体错误

{"type":"validation_error","message":"Validation failed","errors":{"events":["can't be blank"] }}

我能够运行 Curl 命令，它在同一台机器上工作正常，所以我知道它正在工作。

我创建了一个 .net HttpClient 调用来测试基本令牌，它运行良好。

有什么建议吗？

终于回来了，再看代码就明白了。

本来我是把整个URL看成一个大字符串，但一开始没有意识到分隔要传递的值的&符号。

下面的错误代码：

var keyValues = new List<KeyValuePair<string, string>>
{
    new KeyValuePair<string, string>("url",
        "https://requestb.in/17ruxqh1&events[]=invitee.created&events[]=invitee.canceled")
};

应该更改为将每个值从文档中分离出来：

var keyValues = new List<KeyValuePair<string, string>>
{
     new KeyValuePair<string, string>("url","https://requestb.in/17ruxqh1"),
     new KeyValuePair<string, string>("events[]","invitee.created"),
     new KeyValuePair<string, string>("events[]","invitee.canceled")
};

因此，对于那些想要使用 .Net 通过 Calendly 创建 webhook 订阅的人来说，这里有一个完整的 TestMethod 代码可以试用。只需将第一个参数替换为您的 requestb.in 或 post url。同时放入您的 Calendly api 键。

    [TestMethod]
    public void CreateCalendlyWebhookSubscription()
    {
        var task = PostCreateWebhookSubscription();
        task.Wait();
        var response = task.Result;
        var body = response.Content.ReadAsStringAsync().Result;
    }

    private static async Task<HttpResponseMessage> PostCreateWebhookSubscription()
    {
        var client = new HttpClient {BaseAddress = new Uri("https://calendly.com")};
        var request = new HttpRequestMessage(HttpMethod.Post, "/api/v1/hooks/");
        var keyValues = new List<KeyValuePair<string, string>>
        {
            new KeyValuePair<string, string>("url","https://requestb.in/17ruxqh1"),
            new KeyValuePair<string, string>("events[]","invitee.created"),
            new KeyValuePair<string, string>("events[]","invitee.canceled")
        };
        request.Content = new FormUrlEncodedContent(keyValues);
        request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/x-www-form-urlencoded") {CharSet = "UTF-8"};
        request.Content.Headers.Add("X-TOKEN", "<your Calendly ApiKey>");
        return await client.SendAsync(request);
    }

希望这对某人有所帮助！
