自定义API请求

自定义请求响应的API结构

如果你不想使用默认的ApiResult实体作为统一的服务端响应实体,比如说你想要下面的响应实体:

private int errorCode; //请求的错误码
private String errorInfo; //请求错误的原因描述
private T result; //请求的结果
private long timeStamp; //服务端返回的时间戳

(1)首先,继承ApiResult实体,重写其getCodegetMsgisSuccessgetDatasetData方法。

public class CustomApiResult<T> extends ApiResult<T> {

    private int errorCode;
    private String errorInfo;
    private T result;
    private long timeStamp;

    public int getErrorCode() {
        return errorCode;
    }

    public CustomApiResult<T> setErrorCode(int errorCode) {
        this.errorCode = errorCode;
        return this;
    }

    public String getErrorInfo() {
        return errorInfo;
    }

    public CustomApiResult<T> setErrorInfo(String errorInfo) {
        this.errorInfo = errorInfo;
        return this;
    }

    public T getResult() {
        return result;
    }

    public CustomApiResult<T> setResult(T result) {
        this.result = result;
        return this;
    }

    public long getTimeStamp() {
        return timeStamp;
    }

    public CustomApiResult<T> setTimeStamp(long timeStamp) {
        this.timeStamp = timeStamp;
        return this;
    }

    @Override
    public int getCode() {
        return errorCode;
    }

    @Override
    public String getMsg() {
        return errorInfo;
    }

    @Override
    public boolean isSuccess() {
        return errorCode == 0;
    }
    
    @Override
    public void setData(T data) {
        result = data;
    }
    
    @Override
    public T getData() {
        return result;
    }

    @Override
    public String toString() {
        return "ApiResult{" +
                "errorCode='" + errorCode + '\'' +
                ", errorInfo='" + errorInfo + '\'' +
                ", timeStamp='" + timeStamp + '\'' +
                ", result=" + result +
                '}';
    }
}

(2)进行请求的时候使用execute(CallBackProxy)或者execute(CallClazzProxy方法进行请求

XHttp.get("/test/testCustomResult")
            .execute(new CallBackProxy<CustomApiResult<Boolean>, Boolean>(new TipRequestCallBack<Boolean>() {
                @Override
                public void onSuccess(Boolean response) throws Throwable {
                    ToastUtils.toast("请求成功:" + response);
                }
            }){});  //千万注意,这里的{}一定不能去掉,否则解析错误

【注意】上面提示的{}一定不能去掉,否则解析错误, 会报"ApiResult.class.isAssignableFrom(cls) err!!"的错误。

如果你觉得写一长串比较麻烦,你可以自定义请求继承你需要的请求方式,例如这里是get请求,我们可以这样写:

public class CustomGetRequest extends GetRequest {

    public CustomGetRequest(String url) {
        super(url);
    }

    @Override
    public <T> Observable<T> execute(Type type) {
        return execute(new CallClazzProxy<CustomApiResult<T>, T>(type) {
        });
    }

    @Override
    public <T> Disposable execute(CallBack<T> callBack) {
        return execute(new CallBackProxy<CustomApiResult<T>, T>(callBack) {
        });
    }
}

然后我们就可以用自定义的CustomGetRequest进行请求了,是不是简化了很多呢。

new CustomGetRequest("/test/testCustomResult")
        .execute(new TipRequestCallBack<Boolean>() {
            @Override
            public void onSuccess(Boolean response) throws Throwable {
                ToastUtils.toast("请求成功:" + response);
            }
        });

使用自定义的retrofit接口

如果你对retrofit接口情有独钟,我也提供了相应的api方便调用.

1.定义retrofit接口。例如我定义一个用户添加的接口:

/**
 * 使用的是retrofit的接口定义
 */
public interface UserService {
    @POST("/user/registerUser/")
    @Headers({"Content-Type: application/json", "Accept: application/json"})
    Observable<ApiResult<Boolean>> registerUser(@Body RequestBody jsonBody);


    @POST("/user/registerUser/")
    @Headers({"Content-Type: application/json", "Accept: application/json"})
    Observable<ApiResult> register(@Body User user);
}

2.使用XHttp.custom()构建的CustomRequest进行请求,你可以使用apiCallcall进行请求。

  • apiCall: 针对的是retrofit定义的接口,返回的是Observable<ApiResult>的情况,对ApiResult进行拆包,直接获取数据。对于上面定义的第一个接口registerUser

  • call: 针对的是retrofit定义的接口,返回的是Observable的情况,不对ApiResult进行拆包。对于上面定义的第二个接口register

使用示例如下:

CustomRequest request = XHttp.custom();
request.apiCall(request.create(TestApi.UserService.class)
        .registerUser(HttpUtils.getJsonRequestBody(UserManager.getInstance().getRandomUser())))
        .subscribeWith(new TipRequestSubscriber<Boolean>() {
            @Override
            protected void onSuccess(Boolean aBoolean) {
                ToastUtils.toast("添加用户成功!");
            }
        });
CustomRequest request = XHttp.custom();
request.call(request.create(TestApi.UserService.class)
        .register(HttpUtils.getJsonRequestBody(UserManager.getInstance().getRandomUser())))
        .subscribeWith(new TipRequestSubscriber<ApiResult>() {
            @Override
            protected void onSuccess(ApiResult apiResult) {
                ToastUtils.toast("添加用户成功!");
                showResult(JsonUtil.toJson(apiResult));
            }
        });
