.Net 后台访问接口获取数据

 

private AccessToken GetAccessToken(string strUrl) {
//令牌类 可换成请求的实体类
AccessToken token = new AccessToken();
//try {
string szdw = System.Web.Configuration.WebConfigurationManager.AppSettings["placeNumber"].ToString();
string secret = System.Web.Configuration.WebConfigurationManager.AppSettings["secret"].ToString();
//请求接口 最好配置到webconfig
strUrl = strUrl + "api/index?action=token_getAccessToken";
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(strUrl);
//设置请求参数
string json = new JavaScriptSerializer().Serialize(new {
secret = secret,
szdw = szdw
});
//设置请求方式
webRequest.ContentType = "application/json";
webRequest.Accept = "application/json";
webRequest.Method = "POST";
//传参
byte[] buffer = Encoding.GetEncoding("UTF-8").GetBytes(json);
Stream requestStream = webRequest.GetRequestStream();
requestStream.Write(buffer, 0, buffer.Length);
requestStream.Close();
//发送请求，等待服务器返回
var httpResponse = (HttpWebResponse)webRequest.GetResponse();
//将字节流包装为高级的字符流，以便于读取文本内容
using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) {
//读取响应内容
var result = streamReader.ReadToEnd();
//数据反序列化变成可读取数据
JObject jo = (JObject)JsonConvert.DeserializeObject(result);
token.code = jo["code"].ToString();
token.msg = jo["msg"].ToString();
token.expireTime = jo["expire_time"].ToString();
token.accessToken = jo["access_token"].ToString();
//创建文件夹 获取请求日志到本地
string sPath = @"C:xsoft";
if (!Directory.Exists(sPath)) {
Directory.CreateDirectory(sPath);
}
FileStream fs1 = new FileStream(sPath + "data.txt", FileMode.Create, FileAccess.Write);
StreamWriter sw1 = new StreamWriter(fs1);
sw1.WriteLine(jo["code"].ToString() + jo["msg"].ToString());
sw1.Close();
fs1.Close();
}
return token;
}
