Android使用OkHttp发送post请求

本文实例为大家分享了使用okhttp发送post请求的具体代码，供大家参考，具体内容如下

mainactivity.java

public class mainactivity extends appcompatactivity {

 private edittext met_qq;
 private edittext met_pwd;
 private textview mtv_status;

 string path = "http://169.254.53.96:8080/web/loginservlet";

 private static final int success = 665;
 private static final int fall = 894;

 handler handler=new handler(){
  @override
  public void handlemessage(message msg) {
   switch (msg.what) {
    case success:
     string text= (string) msg.obj;
     mtv_status.settext(text);
     break;
    case fall:
     toast.maketext(mainactivity.this, "没有网", toast.length_short).show();
     break;
    default:
     break;
   }
  }
 };

 @override
 protected void oncreate(bundle savedinstancestate) {
  super.oncreate(savedinstancestate);
  setcontentview(r.layout.activity_main);
  //对控件进行初始化操作
  initview();
 }

 private void initview() {
  met_qq = (edittext) findviewbyid(r.id.et_qq);
  met_pwd = (edittext) findviewbyid(r.id.et_pwd);
  mtv_status = (textview) findviewbyid(r.id.tv_status);
 }

 /**
  * 使用post进行表单(键值对)上传,完成登录
  * @param view
  */
 public void login(view view){

  //得到用户输入的信息,进行非空判断
  string qq = met_qq.gettext().tostring().trim();
  string pwd =met_pwd.gettext().tostring().trim();
  if(textutils.isempty(qq) || textutils.isempty(pwd) ){
   toast.maketext(mainactivity.this, "不能输入为空", toast.length_short).show();
   return;
  }

  //1.0 创建okhttpclinet
  okhttpclient okhttpclient = new okhttpclient.builder()
    .connecttimeout(10, timeunit.seconds)
    .readtimeout(10,timeunit.seconds)
    .writetimeout(10,timeunit.seconds)
    .build();

  formbody formbody= new formbody.builder()
    .add("qq", qq).add("pwd", pwd)
    .build();

  request request= new request.builder()
    .post(formbody)
    .url(path)
    .build();

  call call = okhttpclient.newcall(request);

  call.enqueue(new callback() {
   @override
   public void onfailure(call call, ioexception e) {
    handler.sendemptymessage(fall);
   }

   @override
   public void onresponse(call call, response response) throws ioexception {
    string string = response.body().string();
    message msg = message.obtain();
    msg.obj=string;
    msg.what=success;
    handler.sendmessage(msg);
   }
  });
 }
}
