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:

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;
}
}
}
}
一种ASP解决方案。NET核心:
using Newtonsoft.Json;
using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using System.Configuration;
namespace WebApp
{
public static class HttpHelper
{
// In my case this is https://localhost:44366/
private static readonly string apiBasicUri = ConfigurationManager.AppSettings["apiBasicUri"];
public static async Task Post<T>(string url, T contentValue)
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri(apiBasicUri);
var content = new StringContent(JsonConvert.SerializeObject(contentValue), Encoding.UTF8, "application/json");
var result = await client.PostAsync(url, content);
result.EnsureSuccessStatusCode();
}
}
public static async Task Put<T>(string url, T stringValue)
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri(apiBasicUri);
var content = new StringContent(JsonConvert.SerializeObject(stringValue), Encoding.UTF8, "application/json");
var result = await client.PutAsync(url, content);
result.EnsureSuccessStatusCode();
}
}
public static async Task<T> Get<T>(string url)
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri(apiBasicUri);
var result = await client.GetAsync(url);
result.EnsureSuccessStatusCode();
string resultContentString = await result.Content.ReadAsStringAsync();
T resultContent = JsonConvert.DeserializeObject<T>(resultContentString);
return resultContent;
}
}
public static async Task Delete(string url)
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri(apiBasicUri);
var result = await client.DeleteAsync(url);
result.EnsureSuccessStatusCode();
}
}
}
}
要发布，可以使用这样的代码:
await HttpHelper.Post<Setting>($"/api/values/{id}", setting);
删除示例:
await HttpHelper.Delete($"/api/values/{id}");
获取列表的示例:
List<ClaimTerm> claimTerms = await HttpHelper.Get<List<ClaimTerm>>("/api/values/");
示例只获取一个:
ClaimTerm processedClaimImage = await HttpHelper.Get<ClaimTerm>($"/api/values/{id}");
var TakingRequset = WebRequest.Create("http://xxx.acv.com/MethodName/Get");
TakingRequset.Method = "POST";
TakingRequset.ContentType = "text/xml;charset=utf-8";
TakingRequset.PreAuthenticate = true;
//---Serving Request path query
var PAQ = TakingRequset.RequestUri.PathAndQuery;
//---creating your xml as per the host reqirement
string xmlroot=@"<root><childnodes>passing parameters</childnodes></root>";
string xmlroot2=@"<root><childnodes>passing parameters</childnodes></root>";
//---Adding Headers as requested by host
xmlroot2 = (xmlroot2 + "XXX---");
//---Adding Headers Value as requested by host
// var RequestheaderVales = Method(xmlroot2);
WebProxy proxy = new WebProxy("XXXXX-----llll", 8080);
proxy.Credentials = new NetworkCredential("XXX---uuuu", "XXX----", "XXXX----");
System.Net.WebRequest.DefaultWebProxy = proxy;
// Adding The Request into Headers
TakingRequset.Headers.Add("xxx", "Any Request Variable ");
TakingRequset.Headers.Add("xxx", "Any Request Variable");
byte[] byteData = Encoding.UTF8.GetBytes(xmlroot);
TakingRequset.ContentLength = byteData.Length;
using (Stream postStream = TakingRequset.GetRequestStream())
{
postStream.Write(byteData, 0, byteData.Length);
postStream.Close();
}
StreamReader stredr = new StreamReader(TakingRequset.GetResponse().GetResponseStream());
string response = stredr.ReadToEnd();
