第二阶段冲刺二

今天主要完成的任务：OKHttp3框架的学习和应用

遇到的困难：不懂上传文件的原理也不知道改如何上传

解决办法：补充计网的一些知识，参考http传送数据的博客

今日体会：自己一定要学会使用优秀的开源框架，学会阅读github上的文档说明，只有这样，自己才能更好的将框架封装成自己想要的功能，比如说OKHttp3框架

源程序代码

同步GET请求

String url = "http://wwww.baidu.com";
OkHttpClient okHttpClient = new OkHttpClient();
final Request request = new Request.Builder()
        .url(url)
        .build();
final Call call = okHttpClient.newCall(request);
new Thread(new Runnable() {
    @Override
    public void run() {
        try {
            Response response = call.execute();
            Log.d(TAG, "run: " + response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}).start();

　　

POST方式提交String

MediaType mediaType = MediaType.parse("text/x-markdown; charset=utf-8");
String requestBody = "I am Jdqm.";
Request request = new Request.Builder()
        .url("https://api.github.com/markdown/raw")
        .post(RequestBody.create(mediaType, requestBody))
        .build();
OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.newCall(request).enqueue(new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
        Log.d(TAG, "onFailure: " + e.getMessage());
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        Log.d(TAG, response.protocol() + " " +response.code() + " " + response.message());
        Headers headers = response.headers();
        for (int i = 0; i < headers.size(); i++) {
            Log.d(TAG, headers.name(i) + ":" + headers.value(i));
        }
        Log.d(TAG, "onResponse: " + response.body().string());
    }
});
