.NET Core 通过XUnit进行接口单元测试（带请求头及参数）

最近在做core的接口单元测试，所以在这拿出来分享一下，添加XUnit的nuget包

话不多说，直接上代码了：

 [Fact]
        public string GetOrder() 
        {
            string result = "";
            string url = "http://请求地址";
            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
            req.Method = "POST";
            string content = "{ 'data':'','encrypt':'0'}";//添加Post 参数
            #region 请求头
            byte[] data = Encoding.UTF8.GetBytes(content);
            req.Headers.Add("HeadConten", "{ '**': '**'}"); //请求头header
            req.Headers.Add("Client", "{'***': '**’ }"); 
            req.ContentType = "application/json";
            req.ContentLength = data.Length;
            using (Stream reqStream = req.GetRequestStream())
            {
                reqStream.Write(data, 0, data.Length);
                reqStream.Close();
            }
            #endregion
            HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
            Stream stream = resp.GetResponseStream();
            //获取响应内容
            using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
            {
                result = reader.ReadToEnd();
            }
            return result;//返回json格式数据
        }
