其实就是找个地方然后给关键的代码做个笔记什么的……
字符串访问API接口，访问方法为POST：
string url = URL;
string RequestParam = Param;
string headername = HeaderName;
string header = Header;
string html = "";
try
{
WebRequest wbreq = WebRequest.Create(url);
}
catch (WebException WebEx)
{
Console.WriteLine("无法访问的URI:" + "\r\n" + WebEx.ToString());
}
byte[] byteArray = Encoding.UTF8.GetBytes(RequestParam);
{
//POST访问接口
HttpWebRequest RequestInterfaceRequsetByString = (HttpWebRequest)HttpWebRequest.Create(new Uri(URL));
RequestInterfaceRequsetByString.KeepAlive = false;
RequestInterfaceRequsetByString.ProtocolVersion = HttpVersion.Version11;
RequestInterfaceRequsetByString.Method = "post";
RequestInterfaceRequsetByString.ContentType = "application/x-www-form-urlencoded";
RequestInterfaceRequsetByString.Timeout = -1;//超时时间设置为无限大
RequestInterfaceRequsetByString.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0";
Encoding encoding = Encoding.GetEncoding("utf-8");
RequestInterfaceRequsetByString.Headers.Add(headername, Header);
try
{
Stream requeststream = RequestInterfaceRequsetByString.GetRequestStream();
requeststream.Write(byteArray, 0, byteArray.Length);
requeststream.Close();
try
{
HttpWebResponse response = (HttpWebResponse)RequestInterfaceRequsetByString.GetResponse();
Stream responsestream = response.GetResponseStream();
StreamReader sr = new StreamReader(responsestream);
html = sr.ReadToEnd(); //从头读到尾，放到字符串html
responsestream.Close();
response.Close();
}
catch (Exception ex)
{
html = ex.Message;
}
}
catch (Exception ex)
{
html = ex.Message;
}
}
return html;
}
json转字典类型：
public static Dictionary<string, object> ConvertDictionary(string str) { JavaScriptSerializer jss = new JavaScriptSerializer(); //string jsstr = ConvertJsonString(str); try { return jss.Deserialize<Dictionary<string, object>>(str); } catch (Exception ex) { throw new Exception(ex.Message); } }
字典类型访问API接口：与字符串类型访问接口基本类似，但是需要加入字典相关的东西，访问方法为POST
Dictionary<string, object> requestdic = ConvertToDictionary.ConvertDictionary(RequestParam); StringBuilder buffer = new StringBuilder(); int i = 0; foreach (string key in requestdic.Keys) { if (i > 0) { buffer.AppendFormat("&{0}={1}", key, requestdic[key]); } else { buffer.AppendFormat("{0}={1}", key, requestdic[key]); } i++; } byte[] byteArray = Encoding.UTF8.GetBytes(buffer.ToString());
格式化json字符串：
public static string ConvertJsonString(string str) { //格式化json字符串 JsonSerializer serializer = new JsonSerializer(); TextReader tr = new StringReader(str); JsonTextReader jtr = new JsonTextReader(tr); object obj = serializer.Deserialize(jtr); if (obj != null) { StringWriter textWriter = new StringWriter(); JsonTextWriter jsonWriter = new JsonTextWriter(textWriter) { Formatting = Formatting.Indented, Indentation = 4, IndentChar = ‘ ‘ }; serializer.Serialize(jsonWriter, obj); return textWriter.ToString(); } else { return str; } } }
