我需要使用 POST 参数调用 API,例如:
- URL = http://localhost/myAPI/
- ARGS = 选项=蓝色&类型=汽车
我看过 XDocument 但不确定如何在请求中发送参数。我也不确定我将如何异步调用,即使我应该或者在另一个线程中运行是否更好/更容易。
我将从基于 Windows 的 C# 应用程序中调用它。

您可以使用WebClient的上传方法之一。
WebClient client = new WebClient();
string response = client.UploadString(
"http://localhost/myAPI/?options=blue&type=car",
"POST data");
从哪里调用?Javascript?如果是这样,您可以使用 JQuery:
http://api.jquery.com/jQuery.post/
$.post('http://localhost/myAPI/', { options: "blue", type="car"}, function(data) {
$('.result').html(data);
});
data 将包含您的帖子的结果。
如果从服务器端,您可以使用 HttpWebRequest 并使用您的参数写入它的流。
// Create a request using a URL that can receive a post.
WebRequest request = WebRequest.Create ("http://localhost/myAPI/");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "options=blue&type=car";
byte[] byteArray = Encoding.UTF8.GetBytes (postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream ();
// Write the data to the request stream.
dataStream.Write (byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close ();
// Get the response.
WebResponse response = request.GetResponse ();
// Display the status.
Console.WriteLine (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Clean up the streams.
reader.Close ();
dataStream.Close ();
response.Close ();
要将另一个选项放入环中,您可能需要考虑使用 .NET 4.5 中的PostAsync
方法HttpClient
。一个公认的未经测试的刺:
HttpClient client = new HttpClient();
var task = client.PostAsync(string.Format("{0}{1}", "http://localhost/myAPI", "?options=blue&type=car"), null);
Car car = task.ContinueWith(
t =>
{
return t.Result.Content.ReadAsAsync<Car>();
}).Unwrap().Result;
var client = new RestClient("www.api.url");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("id", "givenid");
request.AddHeader("HASH", "generatedHash");
request.AddParameter("text/plain", "fullxml or body", ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
POST /api/somename/1.1
Host: google.com
id: merchantid
HASH: generatedshah
<node1><element>Individual</element></node1>
import http.client
import mimetypes
conn = http.client.HTTPSConnection("url")
payload = "<Node><Element>Individual</Element></Node>"
headers = {
'id': 'givenid',
'HASH': 'generatedhash'
}
conn.request("POST", "/api/blacklist/verify", payload, headers)
res = conn.getresponse()
data = res.read()
print(data.decode("utf-8"))
