使用 C# 的 CRM 2016 web api

Question

我们内部有 CRM 2016，想使用 c# 使用 API :

var credentials = new NetworkCredential(username, password);
HttpClient client = new HttpClient(new HttpClientHandler() {Credentials = credentials});
client.BaseAddress = new Uri("https://xxx.elluciancrmrecruit.com/api/data/v8.0/datatel_events");
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = client.GetAsync("datatel_events?$orderby=datatel_eventname").Result;
if (response.IsSuccessStatusCode)
{
   var yourcustomobjects = response.Content.ReadAsStringAsync();
}
else
{
   //Something has gone wrong, handle it here
}

但它总是 return HTML 页面说稍后再试，而不是 json 响应。

Answer 1

假设 date1_events 是一个自定义实体（尽管命名约定似乎不符合），您应该查询 OData 端点以获取您正在寻找的信息。

以查询为例 contacts:

var credentials = new NetworkCredential(username, password);
var client = new HttpClient(new HttpClientHandler() {Credentials = credentials})
{
    BaseAddress = new Uri("https://xxx.elluciancrmrecruit.com/api/data/v8.0/")
};
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var response = client.GetAsync("accounts?$top=1").Result;
if (response.IsSuccessStatusCode)
{
    var yourcustomobjects = response.Content.ReadAsStringAsync();
}
