webservice_rest接口_学习笔记

1、声明WebClientUtil工具类

public class WebClientUtil {

BufferedReader reader = null;
StringBuffer resultBuffer = new StringBuffer();

if (params != null)
{
parameterData = "";
if("json".equals(dataType)){
parameterData = JSON.toJSONString(params);
}else{
for (String key : params.keySet()) {
parameterData = parameterData + (parameterData.equals("") ? "" : "&") + key + "=" + URLEncoder.encode(String.valueOf(params.get(key)), "UTF8");
}
}
}
HttpURLConnection httpURLConnection = getHttpURLConn(url, parameterData,"POST",token,contentType,connectTimeout,readTimeout);

}
URLConnection connection = localURL.openConnection();
HttpURLConnection httpURLConnection = (HttpURLConnection)connection;
httpURLConnection.setDoOutput(true);
if(connectTimeout > 0){
httpURLConnection.setConnectTimeout(connectTimeout);//设置连接超时
}

}
httpURLConnection.setRequestMethod(mode);
httpURLConnection.setRequestProperty("Accept","*");
httpURLConnection.setRequestProperty("connection","Keep-Alive");
httpURLConnection.setRequestProperty("Accept-Charset","utf-8");
if(StrUtil.isNotNull(contentType)){

}

private static void closeStream(OutputStream outputStream, OutputStreamWriter outputStreamWriter, InputStream inputStream, InputStreamReader inputStreamReader, BufferedReader reader)

3、postman检测接口是否可以正常调用

http://127.0.0.1:8080/rdpe-shanxi/rest/commonApiRestful.action?jsonStr={
"action": "txMktSmsSend",
"params": {
"pageNo" : 3,
"busiCode" : "",
"triggerCount" : "",
"eventType" : ""
}
}
