Retrofit进行post提交json数据

Posted 2020-10-15 gali

1：先看一看xutils3的提交代码

 　　　
　　　　　    String account = editText1.getText().toString();
                String password = editText2.getText().toString();
                JSONObject js_request = new JSONObject();//服务器需要传参的json对象
                try {
                    js_request.put("account", account);//添加相应键值对
                    js_request.put("password", password);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
                RequestParams requestParams = new RequestParams(LOGIN_URL);
                requestParams.setAsJsonContent(true);
                requestParams.setBodyContent(js_request.toString());
                x.http().post(requestParams, new Callback.CommonCallback<String>() {
                    @Override
                    public void onSuccess(String result) {
                        System.out.println("**ok"+result);
                        try {
                            JSONObject object = new JSONObject(result);
                            String code = object.getString("code");
                            if (code.equals("1")) {
                                // button.setClickable(false);
                                //登录成功后获得id
                            
                            } else {
                                // 登陆失败
                            }

                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                    }
                    @Override
                    public void onError(Throwable ex, boolean isOnCallback) {
                        System.out.println("errot");
                    }

                    @Override
                    public void onCancelled(CancelledException cex) {
                    }
                    @Override
                    public void onFinished() {
                    }
                });
            }

   2：Retrofit提交过程

  2.1 登陆 urL 

  public static String LOGIN_URL = "http://114.xx.xxx.xx:8088/vdyweb/ws/rest/Login";

　　

 interface APIStore {

    @Headers({"Content-Type: application/json","Accept: application/json"})//需要添加头
    @POST ("vdyweb/ws/rest/Login")
    Call<ResponseBody>getMessage(@Body RequestBody info);   // 请求体味RequestBody 类型

} 

 

public class Info {
    String account;
    String password;

    public Info(String account, String password) {
        this.account = account;
        this.password = password;
    }
}

　

public class MainActivity extends AppCompatActivity {

    public static String BASE_LOGIN_URL = "http://114.xx.xxx.xx:8088/";
    Retrofit retrofit;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Info info=new Info("test","123456");
 　　/*** 利用Gson 将对象转json字符串*/
        Gson gson=new Gson();
        String obj=gson.toJson(info);
        retrofit=new Retrofit.Builder().baseUrl(BASE_LOGIN_URL).build();
        RequestBody body=RequestBody.create(okhttp3.MediaType.parse("application/json; charset=utf-8"),obj);
        final APIStore login = retrofit.create(APIStore.class);
        retrofit2.Call<ResponseBody> data = login.getMessage(body);
        data.enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(retrofit2.Call<ResponseBody> call, Response<ResponseBody> response) {
                Log.d(TAG, "onResponse: --ok--"+response.body());
                try {
                    Log.d(TAG, "onResponse: --ok--"+response.body().string());
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            @Override
            public void onFailure(retrofit2.Call<ResponseBody> call, Throwable t) {
                Log.d(TAG, "onResponse: --err--"+t.toString());
            } });
} } 

3：添加get请求

  apiStore加

    @GET("vdyweb/ws/rest/device/getOwnerDevice/2/2/20")
    Call<ResponseBody>getMessage2();

　　

 retrofit2.Call<ResponseBody>data1=login.getMessage2();
        data1.enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                try {
                    Log.d(TAG, "onResponse: --ok--"+response.body().string());
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            @Override
            public void onFailure(Call<ResponseBody> call, Throwable t) {

            }
        });
