详解使用Spring的restTemplete进行Http请求

最近学习spring框架，本文介绍了使用spring的resttemplete进行http请求，留个笔记

/*
* rest templete
*/
public class resttemplatetest {
  //private static string url = "http://10.2.1.46:8080";
  private static string url = "http://127.0.0.1:8080/test";
  private static string autodeploy = "/api/ddd/manages/yyy/1111";

  public static void main(string[] args) throws unsupportedencodingexception {
    jsonobject token1 = logintest.login(url);
    jsonobject token = new jsonobject();
    token.put("token", token1.getstring("token"));
    token.put("username", "[e-mail]");
    string name = "明辰晨";
    token.put("name", urlencoder.encode(name, "utf-8"));

    string jsonbody = dmsautodeploytest.dmsautodeploydata();
    autodeploy(jsonbody,token.tojsonstring());
  }

  /*
  * 主要的post方法
  */
  public static void autodeploy(string json,string token){
    string autodeployurl = url + autodeploy;
    resttemplate resttemplate = new resttemplate();
    httpheaders headers = new httpheaders();
    //一定要设置好contenttype为utf8否则会乱码
    mediatype type = mediatype.parsemediatype("application/json; charset=utf-8");
    headers.setcontenttype(type);
    headers.add("accept", mediatype.application_json.tostring());
    headers.add("authentication", token);//设置自定义session header

    httpentity<string> formentity = new httpentity<string>(json, headers);

    map<string, object> parametermap = new hashmap<>();
    //entity = header，urivariables = parameters;
    resttemplate.postforobject(autodeployurl, formentity, string.class, parametermap);
  }

  /*
  * 测试
  */
  public static void test4(){
      jsonobject response = null;
      map<string,object> param = new hashmap<>();
      param.put("ming", "chyen");

      string json = "haha";
      try {
        response = restutil.post("http://127.0.0.1:8080/cloud-master/api/release/manages/detail", jsonobject.class,null,null,json);
      } catch (exception e) {
        e.printstacktrace();
      }
      system.out.println(response);
  }
  /**
   * 测试
   */
  public static void test(){
    resttemplate resttemplate = new resttemplate();

    map<string, object> parametermap = new hashmap<>();
    resttemplate.getforobject("url", string.class,parametermap);
    //factory.createrequest(uri, httpmethod)
  }
}
