问题描述
如何直接从代码隐藏调用 ASP.NET Web API?或者我应该调用从代码隐藏中调用 getJSON 方法的 javascript 函数?
How would I call an ASP.NET Web API directly from code-behind? Or should I be calling my javascript function that calls the getJSON method from code-behind?
我通常有这样的事情:
function createFile() { $.getJSON("api/file/createfile", function (data) { $("#Result").append('Success!'); }); }任何指针表示赞赏.TIA.
Any pointers appreciated. TIA.
*我使用的是 WebForms.

推荐答案如果必须自己调用 web 服务,可以尝试使用 HttpClient 如 Henrik Neilsen 所述.
If you must call the web service itself, you can try using HttpClient as described by Henrik Neilsen.
更新的 HTTPClient 示例
一个基本的例子:
// Create an HttpClient instance HttpClient client = new HttpClient(); // Send a request asynchronously continue when complete client.GetAsync(_address).ContinueWith( (requestTask) => { // Get HTTP response from completed task. HttpResponseMessage response = requestTask.Result; // Check that response was successful or throw exception response.EnsureSuccessStatusCode(); // Read response asynchronously as JsonValue response.Content.ReadAsAsync<JsonArray>().ContinueWith( (readTask) => { var result = readTask.Result //Do something with the result }); });更多推荐
