OKHTTP封装使用

最近比较火的是OKhttp+picasso解析混合使用
接下来我们先上Okhttp抓抓数据。

显然Okhttp里面的那个onResponse 和 onFailure是非UI线程，那么我们改变他的话只有发送个通知出来让其他的UI线程来处理UI变化了，这个时候，屌丝王Handler出场了。

1.okhttp的get请求封装
直接上代码:

    public static final int ok_error = -1;
    public static final int ok_success = 1;

    /**
     * okhttp Post请求方式
     */
    public static void OKdoGet(String url, final Handler handler) {

        OkHttpClient client = new OkHttpClient();
        final Request request = new Request.Builder().url(url).build();
        // new call
        Call call = client.newCall(request);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Request request, IOException e) {
                handler.sendEmptyMessage(ok_error);
            }
            @Override
            public void onResponse(final Response response) throws IOException {
                String resultStr = response.body().string();
                Message msg = new Message();
                msg.what = ok_success;
                msg.obj = resultStr;
                handler.sendMessage(msg);
            }
        });
    }

至于Handler里面怎么拿自行脑补。

2.Okhttp的post请求封装

/**
     * Post请求的封装
     */
    public static void OKdoPost(String url, final Handler handler,
            FormEncodingBuilder builder) {
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder().url(url).post(builder.build())
                .build();
        client.newCall(request).enqueue(new Callback() {

            @Override
            public void onFailure(Request arg0, IOException arg1) {
                handler.sendEmptyMessage(ok_error);
            }

            @Override
            public void onResponse(Response arg0) throws IOException {
                String resultStr = arg0.body().string();
                Message msg = new Message();
                msg.what = ok_success;
                msg.obj = resultStr;
                handler.sendMessage(msg);
            }
        });
    }

    /**
     * Post请求的封装
     */
    public static void OKdoPostWithCode(String url, final Handler handler,
            FormEncodingBuilder builder, final int success, final int error) {
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder().url(url).post(builder.build())
                .build();
        client.newCall(request).enqueue(new Callback() {

            @Override
            public void onFailure(Request arg0, IOException arg1) {
                handler.sendEmptyMessage(error);
            }

            @Override
            public void onResponse(Response arg0) throws IOException {
                String resultStr = arg0.body().string();
                Message msg = new Message();
                msg.what = success;
                msg.obj = resultStr;
                handler.sendMessage(msg);
            }
        });
    }

因为他传值是不定的，所以咱把FormEncodingBuilder 给抽出来另外加，这样想怎么传就怎么传，再者不知道他是成功还是失败，所以就弄了多的两个判断的。

3.post请求的参数方法

       /**
         * post请求
         */
        FormEncodingBuilder builder = new FormEncodingBuilder();
        builder.add("sj_id", "1");
        builder.add("xx", "1");
        builder.add("page", page + "");
        builder.add("oauth_token", "f5fbefc2bd9f538c3010fd24f57eb536");
        OkHttpUtil.OKdoPost(ContextUrl.url, handler, builder);//Post请求方法调用

       /**
         * post请求  带请求码
         */
        FormEncodingBuilder builder = new FormEncodingBuilder();
        builder.add("sj_id", "1");
        builder.add("xx", "1");
        builder.add("page", page + "");
        builder.add("oauth_token", "f5fbefc2bd9f538c3010fd24f57eb536");
        OkHttpUtil.OKdoPostWithCode(ContextUrl.url, handler, builder, 3, 4);

OKhttp暂时说到这里，有啥加的再上。
