HTTP接口目前接触到的有两种：
①.共同点：
模式相同，接口方法大致相同，
②.不同点：
传参方式不同
HttpWebRequest中的ContentType方法不同
键值对方式为：“application/x-www-form-urlencoded”
非键值对为： “application/json”;
1.接口请求体为键值对方式
键值对请求体样例：
Srv中先定义：
private static readonly string DefaultUserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";
接口方法：
string url = "http://10.40.95.30/nwom/plugins/jswebservice/siteperformanceassess/assessResult.ilf"; --接口地址
string outData = "";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "post";
req.ContentType = "application/x-www-form-urlencoded";
req.UserAgent = DefaultUserAgent;
Encoding requestEncoding = Encoding.GetEncoding("UTF-8");
string repData = JsonConvert.SerializeObject(opDetailList); --opDetailList为请求体
StringBuilder buffer = new StringBuilder();
buffer.AppendFormat("{0}={1}", "opDetail", repData); --opDetail为键（按照他的要求定义键），repData值（解析之后的请求体）
byte[] postData = requestEncoding.GetBytes(buffer.ToString());
using (Stream reqStream = req.GetRequestStream())
{
reqStream.Write(postData, 0, postData.Length);
}
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
using (Stream stream = resp.GetResponseStream())
{
using (StreamReader sr = new StreamReader(stream, Encoding.UTF8))
{
outData = sr.ReadToEnd();
}
}
if (outData != null)
{
}
2.接口请求体非键值对
非键值对请求体样例：
"{
" alarmtitle \ ": [“基站退服”,“小区退服”],
\ "exResId \ ":[“2026413640”,“2031327029”],
\ "alarmnetype \ ":[“BTS”,“NodeB”],
\ "startEventTime\ ": 1542536234,
\ "endEventTime\ ": 1542709034
}"
接方法口：
UserNum un = new UserNum();
un.userName = userName;
un.password = passWord;
string repData = JsonConvert.SerializeObject(un);
byte[] postData = Encoding.UTF8.GetBytes(repData);
//ERP导入项目的API地址
string importProjectApiUrl = "http://10.40.9.185:60001/cloud/ailk-cms-ms-uac/auth";
string outData = "";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(importProjectApiUrl);
req.Method = "post";
req.ContentType = "application/json";
using (Stream reqStream = req.GetRequestStream())
{
reqStream.Write(postData, 0, postData.Length);
}
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
using (Stream stream = resp.GetResponseStream())
{
using (StreamReader sr = new StreamReader(stream, Encoding.UTF8))
{
outData = sr.ReadToEnd();
}
}
if (outData != null)
{
}
特殊实例：
接口方要求请求接口时带参数：
类似：
curl -XPOST -H ‘Content-Type:application/json;charset=utf-8’ -H ‘Authorization:eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJhY2Nfb2lkIjo0NzQsImFyZWFfbmFtZSI6ImFkbWluLmNvbSIsInN1YiI6ImNtcyIsInNwZWNpYWx0eSI6WzEsMiwzLDQsNSw2LDddLCJhY2NfbG9naW5uYW1lIjoiYWlsayIsImltc19waG9uZSI6IjE1MDYyMjA1NDk2IiwiYXJlYV9pZCI6MSwicm9sZV9uYW1lIjoiU1lTVEVNIiwiY2l0eV9uYW1lIjoi5rGf6IuP55yBIiwiY2l0eV9sYXllciI6MSwicm9sZV9pZCI6MSwiZXhwIjoxNTQ3ODA0MTk4LCJjaXR5X2lkIjoiMDAiLCJ0aW1lc3RhbXAiOjE1NDc4MDA1OTgwNDV9.I-MApLklxH4Zs3AGxWofwU3CLZpsFCFEY_knmrbqYVFuZbKnhHpZry3jzOXWa7aBoHbdLKz28ogIlIz9Y8OOCg’ ‘10.40.9.185:60001/cloud/ailk-cms-ms-alarmquery/size’ -d ‘{
“alarmtitle”:[“基站退服”,“小区退服”],
“exResId”:[“2026413640”,“2031327029”],
“alarmnetype”:[“BTS”,“NodeB”],
“startEventTime”:1542816000,
“endEventTime”:1542844800
}’
（绿色为请求参数中的键，红色为值，类似系统中处理页面的url?id=id）
只需要
HttpWebRequest req2 = (HttpWebRequest)WebRequest.Create(importProjectApiUrl2);
req2.Headers.Add(“Authorization”, Authorization); --前面的Authorization为上面标记中绿色部分，后面的Authorization为上方标记中红色部分
