通过okhttp网络请求方式获取到接口里参数path的MP4文件，麻烦写下完整的代码。我不知道怎么解析返回的数据
我的代码如下所示：
public class MainActivity extends AppCompatActivity {
final OkHttpClient client = new OkHttpClient();
// private final Gson gson = new Gson();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getRequest();
}
private void getRequest() {
final Request request = new Request.Builder()
.get()
.tag(this)
.url("http://huaruanyun.cn:19001/get_play_list?devno=7C0CC5C2E3D69960")
.build();
new Thread(new Runnable() {
@Override
public void run() {
Response response = null;
try {
response = client.newCall(request).execute();
if (response.isSuccessful()) {
String result = response.body().string();
Log.i("qp", "打印GET响应的数据：" + result);
} else {
throw new IOException("Unexpected code " + response);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
}
}
String result = response.body().string();
JSONObject jsonObject = new JSONObject(result);
JSONArray jsonItems = jsonObject.getJSONArray("items");
for (int i = 0; i < jsonItems.length(); i++) {
JSONArray jsonData = jsonItems.getJSONObject(i).getJSONArray("tpl_data");
for (int e = 0; e < jsonData.length(); e++) {
JSONArray jsonContent = jsonData.getJSONObject(e).getJSONArray("content");
for (int n = 0; n < jsonContent.length(); n++) {
path = jsonContent.getJSONObject(0).getString("path");
}
}
}

http请求可根据自身需求，使用get或者post，传对应的参数即可
