xUtils 的 post和get 请求 使用记录

xUtils 的 post和get 请求 使用记录.最后有规范的代码。开始的只是过程

post请求:

刚开始不知道怎么添加请求参数，就自己动手尝试。最后通过下面的代码请求成功了。

        RequestParams params = new RequestParams(HttpUrl.add_to_cars);//里面参数为请求地址
// 请求参数
//        {
//            "memberId": "297ebe0e528b62cd01528c36ed02005c",
//            "commCommodityId": "2c95869052f8659c0152f865fa940000",
//            "commCount": "20"
//        }
	//直接使用了拼接字符串。  
        params.setBodyContent("{\"memberId\":\"" + "297ebe0e528b62cd01528c36ed02005c"
                + "\",\"commCommodityId\":\"" + goodsId + "\",\"commCount\":\""
                + String.valueOf(chooseCount) + "\"}");
        Callback.Cancelable cancelable = x.http().post(params, new Callback.CommonCallback<TestBean>() {
            @Override
            public void onSuccess(TestBean baseBean) {
                showToast(baseBean.message);
            }
            @Override
            public void onError(Throwable ex, boolean b) {
                Toast.makeText(x.app(), ex.getMessage(), Toast.LENGTH_LONG).show();
            }
            @Override
            public void onCancelled(CancelledException e) {
                //  Toast.makeText(x.app(), "cancelled", Toast.LENGTH_LONG).show();
            }
            @Override
            public void onFinished() {
            }
        });

TestBean.java

@HttpResponse(parser = JsonResponseParser.class)
public class TestBean extends BaseBean {
    /**
     * data : null
     */
    public Object data;
}
BaseBean.java
public class BaseBean implements Parcelable {
    /**
     * message : 
     * count : 3
     * curCount : 0
     * success : true
     */
    public String message;
    public int count;
    public int curCount;
    public boolean success;
    @Override
    public int describeContents() {
        return 0;
    }
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(this.message);
        dest.writeInt(this.count);
        dest.writeInt(this.curCount);
        dest.writeByte(success ? (byte) 1 : (byte) 0);
    }
    public BaseBean() {
    }
    protected BaseBean(Parcel in) {
        this.message = in.readString();
        this.count = in.readInt();
        this.curCount = in.readInt();
        this.success = in.readByte() != 0;
    }
    public static final Parcelable.Creator<BaseBean> CREATOR = new Parcelable.Creator<BaseBean>() {
        public BaseBean createFromParcel(Parcel source) {
            return new BaseBean(source);
        }
        public BaseBean[] newArray(int size) {
            return new BaseBean[size];
        }
    };
}

get方式:

get方式比较简单，只需要把下面的url改成你的请求地址，把Object 改成请求返回的Json数据实体类就行了。

还有就是记得在改的实体类之前加上这个@HttpResponse(parser = JsonResponseParser.class)。例子如下

@HttpResponse(parser = JsonResponseParser.class)
public class GoodsDetailsBean extends BaseBeanget请求例子

RequestParams params = new RequestParams(url);//url是get的请求地址

Callback.Cancelable cancelable = x.http().get(params, new Callback.CommonCallback<Object>() {
    @Override
    public void onSuccess(Object o) {
	//请求成功
    }

    @Override
    public void onError(Throwable throwable, boolean b) {
		//请求出错
    }    @Override    public void onCancelled(CancelledException e) {
		//请求取消
    }    @Override    public void onFinished() {
		//请求完成
    }});

后面发现有规范的代码如下。

public class HttpUtils {

    // get请求方式
    public static void getDataFromWeb(Callback.CommonCallback callback, String url) {
        RequestParams params = new RequestParams(url);
        x.http().get(params, callback);
    }

    // post请求方式
    public static void postDataFromWeb(Object entity, Callback.CommonCallback callback, String url) {
        RequestParams params = new RequestParams(url);
        String str = JsonBinder.buildNonNullBinder().toJson(entity);
        params.setAsJsonContent(true);
        params.addBodyParameter("", str, "application/json");
        x.http().post(params, callback);
    }
}

get请求就可以改为这样，Object为请求返回的实体类,记得在改的实体类之前加上这个@HttpResponse(parser = JsonResponseParser.class)。url为请求地址.HttpUtils.getDataFromWeb(new Callback.CommonCallback<Object>() {
    @Override
    public void onSuccess(Object bean) {
    }
    @Override
    public void onError(Throwable throwable, boolean b) {
    }
    @Override
    public void onCancelled(CancelledException e) {
    }
    @Override
    public void onFinished() {
    }
}, url);

post请求可以改成这样.object和url和上面一样。PostBean是post请求参数组成的一个自定义的请求类。只要把请求参数传进这个类的构造方法里面去就好了PostBean bean = new PostBean("?","?","?");
HttpUtils.postDataFromWeb(bean, new Callback.CommonCallback<Object>() {
    @Override
    public void onSuccess(Object o) {
    }
    @Override
    public void onError(Throwable throwable, boolean b) {
    }
    @Override
    public void onCancelled(CancelledException e) {
    }
    @Override
    public void onFinished() {
    }
}, url);
class PostBean {
    String ?;
    String ?;
    String ?;
    public PostBean(String ?, String ?, String ?) {
        this.?= ?;
        this.?= ?;
        this.?= ?;
    }
}
