    Post表单提交-单个参数 @Field

    • 接口
      /** 表单提交要加 @FormUrlEncoded
         * 登录
         * @param username 用户名
         * @param password 密码
         * @param deviceId 设置ID
         * @param platform 平台这里是Android
         * @param verId 版本号
         * @return
         */
        @FormUrlEncoded
        @POST("login")
        Call<String> login(@Field("loginName") String username,
                           @Field("password") String password,
                           @Field("deviceId") String deviceId,
                           @Field("platform") String platform,
                           @Field("verId") String verId);
    
    • 调用
        private void login(){
    
            /**
             * 初始化
             */
            Retrofit retrofit = new Retrofit.Builder()
                     .baseUrl(baseUrl)
                    .addConverterFactory(ScalarsConverterFactory.create())
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
    
            //生成对象的Service
            LoginService loginService = retrofit.create(LoginService.class);
            //调用方法得到Call

                    getDeviceId(),
                    PLATFORM,

                   L.d("vivi",t.toString());
                }
            });
    
        }
    
        /**
         * 获取设备号

            L.d("vivi",deviceId);
    
            return deviceId;
        }
    
    • 权限
        <!--读取手机状态的权限-->
        <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    
    • 结果
    OK   {"msg":"OK","result":{"accessToken":"A0BdgCrMG22CwfSKrlsEPAs3ZAozND","securiyCode":"5jUduYno","time":null,"userId":"402882823a9d5e0d013a9dabe3680002","userName":"home","verId":"V1.0"},"status":1,"verId":"1.0"}
    

    Post表单提交-多个参数-@FieldMap

    
        /**
         * 表单提交要加 @FormUrlEncoded 
         * Post使用map多参数
         * @param params
         * @return
         */
        @FormUrlEncoded
        @POST("login")
        Call<LoginBean> login2(@FieldMap Map<String,String>params);
    
    • 调用
    
            /**
             * 初始化
             */
            Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(ScalarsConverterFactory.create())
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
    
            Map<String, String> hashMap = new HashMap<String, String>();
            hashMap.put("loginName", "home123");
            hashMap.put("password", "123456");
            hashMap.put("deviceId", getDeviceId());
            hashMap.put("platform", PLATFORM);
            hashMap.put("verId", VERSION_ID);
    
            //生成对象的Service
            LoginService loginService = retrofit.create(LoginService.class);
    
            //调用方法得到Call
            Call<LoginBean> loginCall = loginService.login2(hashMap);
    
            //异步执行
            loginCall.enqueue(new Callback<LoginBean>() {
                @Override
                public void onResponse(Call<LoginBean> call, Response<LoginBean> response) {
    
                    L.d("vivi",response.message()+"   "+response.body().toString());
                }
    
                @Override
                public void onFailure(Call<LoginBean> call, Throwable t) {
    
                    L.d("vivi",t.getMessage());
                    L.d("vivi",t.toString());
                }
            });
    

    结果与第一个一样,这样就拿到token

    使用@HeaderMap过滤请求 动态添加请求动

    @Headers()
    这个是写在方法上的
    如果请求头是固定的,就可以使用这个

    @Header与@HeaderMap作为参数使用的
    请求头不固定,要动态添加 就使用,2个用法就和@Field 与@FieldMap一样

    • 接口
     
        @POST("p/userCenter")
        Call<String> getUserCenter(@HeaderMap Map<String,String> headers);
    
    
    • 调用
     private void getUserInfo(){
            
            /**
             * 初始化
             */
            Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(ScalarsConverterFactory.create())
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
    
            //生成对象的Service
            LoginService loginService = retrofit.create(LoginService.class);
          /*  SimpleDateFormat     dateFormat   = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    
            String              date  = dateFormat.format(new Date());*/
    
            /**
             * 这里测试参数写死了,实际可以改变,
             */
            Map<String, String> headers = new HashMap<String, String>();
            headers.put("userId", "402882823a9d5e0d013a9dabe3680002");
            headers.put("userName", "home");
            headers.put("accessToken", "A0BdgCrMG22CwfSKrlsEPAs3ZAozND");
            //当前时间,因为后台加密,原因写死 
            headers.put("time", "2016-10-27 13:28:07");
            headers.put("verId","V1.0");
    
        //这个是加载后的数据后台接收后,同样有一个比对
            String validateCode = "674BA63B66D0D4A1E6C9EED16CE193C7";
            headers.put("code", validateCode);
    
            Call<String> userCall = loginService.getUserCenter(headers);
            userCall.enqueue(new Callback<String>() {
                @Override
                public void onResponse(Call<String> call, Response<String> response) {
                    L.d("vivi",response.message()+"   "+response.body());
                }
    
                @Override
                public void onFailure(Call<String> call, Throwable t) {
                    L.d("vivi",t.getMessage());
                    L.d("vivi",t.toString());
                }
            });
    
        }
    
    • 结果
    OK   {"msg":"OK","result":{"availablePredeposit":28,"favoriteLength":2,"messageCount":1,"nickName":"home123","portraitPic":"2016/10/27/92f2272d-cf41-4f22-bf46-905575197441.jpg","score":602,"subCountsDtoList":[{"status":"UNPAY","subCounts":15},{"status":"PADYED","subCounts":1},{"status":"SUCCESS","subCounts":1},{"status":"CLOSE","subCounts":3}],"userId":"402882823a9d5e0d013a9dabe3680002","userMobile":"13800138000","userName":"home"},"status":1,"verId":"1.0"}
    
    • 如果传过去是一个空的map就请求不到数据
    OK   {"msg":"401 user validate failed" ,"result":null,"status":"401","verId":"1.0"}
    

    @Headers()
    @Header()
    @HeaderMap
    基本上是用于过滤请求的

      • 沈敏杰:不错:+1:,其实你的接口还能封装一下,如网络请求的回调,入参封装成一个class等
