Get同步请求

new Thread(new Runnable() {
@Override
public void run() {
try {
Response response = okHttpClient.newCall(request).execute();
final String string = response.body().string();
runOnUiThread(new Runnable() {
@Override
public void run() {
btn_1.setText(string);
}
});

} catch (IOException e) {
e.printStackTrace();
}
}
}).start();

Get异步请求

okHttpClient.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {

}

@Override
public void onResponse(Call call, Response response) throws IOException {
final  String strgin = response.body().string();
runOnUiThread(new Runnable() {
@Override
public void run() {
btn_1.setText(strgin);
}
});
}
});

Post请求提交 String Json 文件类型等

文件的下载
