这是我到目前为止的代码:
public class Class1
{
private const string URL = "https://sub.domain.com/objects.json?api_key=123";
private const string DATA = @"{""object"":{""name"":""Name""}}";
static void Main(string[] args)
{
Class1.CreateObject();
}
private static void CreateObject()
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = DATA.Length;
StreamWriter requestWriter = new StreamWriter(request.GetRequestStream(), System.Text.Encoding.ASCII);
requestWriter.Write(DATA);
requestWriter.Close();
try {
WebResponse webResponse = request.GetResponse();
Stream webStream = webResponse.GetResponseStream();
StreamReader responseReader = new StreamReader(webStream);
string response = responseReader.ReadToEnd();
Console.Out.WriteLine(response);
responseReader.Close();
} catch (Exception e) {
Console.Out.WriteLine("-----------------");
Console.Out.WriteLine(e.Message);
}
}
}
问题是我认为异常块正在被触发(因为当我删除try-catch时，我得到一个服务器错误(500)消息。但是我没有看到控制台。我在catch block里放了几行。
我的控制台:

我们已经开始使用地下酒吧了。这很棒:

// create a client
var client = HttpClient.Create("http://example.com/api");
// get some companies!
var companies = client.Get("companies").OnOk().As<List<Company>>();
// upload a company, with validation error support
client.Post(company, "companies")
.On(HttpStatusCode.BadRequest, (List<ValidationError> errors) => {
Console.WriteLine("Ruh Roh, you have {0} validation errors", errors.Count());
})
.On(HttpStatusCode.Created, () => Console.WriteLine("Holy moly you win!"));
// update a company
client.Put(company, "company/:id", new { id = "awesome-sauce" })
.OnOk(() => Console.WriteLine("Company updated"));
// run a search
client.Get("images/:category", new { category = "cats", breed = "omg the cutest", size = "kittens" })
.OnOk().As<List<Image>>();
// make an asynchronous request
var response = await client.GetAsync("companies/:id", new { id = 5 })
response.OnOk(UpdateCompaniesCallback)
请使用以下代码进行REST API请求:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Text;
using System.Json;
namespace ConsoleApplication2
{
class Program
{
private const string URL = "https://XXXX/rest/api/2/component";
private const string DATA = @"{
""name"": ""Component 2"",
""description"": ""This is a JIRA component"",
""leadUserName"": ""xx"",
""assigneeType"": ""PROJECT_LEAD"",
""isAssigneeTypeValid"": false,
""project"": ""TP""}";
static void Main(string[] args)
{
AddComponent();
}
private static void AddComponent()
{
System.Net.Http.HttpClient client = new System.Net.Http.HttpClient();
client.BaseAddress = new System.Uri(URL);
byte[] cred = UTF8Encoding.UTF8.GetBytes("username:password");
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(cred));
client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
System.Net.Http.HttpContent content = new StringContent(DATA, UTF8Encoding.UTF8, "application/json");
HttpResponseMessage messge = client.PostAsync(URL, content).Result;
string description = string.Empty;
if (messge.IsSuccessStatusCode)
{
string result = messge.Content.ReadAsStringAsync().Result;
description = result;
}
}
}
}

response.OnOk(UpdateCompaniesCallback)
第一步是为HTTP客户机创建helper类。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;
namespace callApi.Helpers
{
public class CallApi
{
private readonly Uri BaseUrlUri;
private HttpClient client = new HttpClient();
public CallApi(string baseUrl)
{
BaseUrlUri = new Uri(baseUrl);
client.BaseAddress = BaseUrlUri;
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
}
public HttpClient getClient()
{
return client;
}
public HttpClient getClientWithBearer(string token)
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
return client;
}
}
}
然后可以在代码中使用这个类。
这是如何使用上面的类调用不带承载的REST API的示例。
// GET API/values
[HttpGet]
public async Task<ActionResult<string>> postNoBearerAsync(string email, string password,string baseUrl, string action)
{
var request = new LoginRequest
{
email = email,
password = password
};
var callApi = new CallApi(baseUrl);
var client = callApi.getClient();
HttpResponseMessage response = await client.PostAsJsonAsync(action, request);
if (response.IsSuccessStatusCode)
return Ok(await response.Content.ReadAsAsync<string>());
else
return NotFound();
}
这是一个如何调用需要承载的REST API的示例。
// GET API/values
[HttpGet]
public async Task<ActionResult<string>> getUseBearerAsync(string token, string baseUrl, string action)
{
var callApi = new CallApi(baseUrl);
var client = callApi.getClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
HttpResponseMessage response = await client.GetAsync(action);
if (response.IsSuccessStatusCode)
{
return Ok(await response.Content.ReadAsStringAsync());
}
else
return NotFound();
}
