要解决"Asynctask在getInputStream()上挂起"的问题,可以尝试以下解决方法:
ExecutorService executor = Executors.newFixedThreadPool(1);
executor.execute(new Runnable() {
@Override
public void run() {
try {
URL url = new URL("your_url");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
InputStream inputStream = connection.getInputStream();
// 处理输入流
} catch (Exception e) {
e.printStackTrace();
}
}
});
executor.shutdown();
protected String doInBackground(String... params) {
String result = null;
try {
URL url = new URL("your_url");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.connect();
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
InputStream inputStream = connection.getInputStream();
// 处理输入流
}
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
首先,将以下依赖项添加到build.gradle文件中:
implementation 'com.squareup.okhttp3:okhttp:4.9.1'
然后,使用以下代码进行网络请求:
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("your_url")
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
}
@Override
public void onResponse(Call call, Response response) throws IOException {
if (response.isSuccessful()) {
InputStream inputStream = response.body().byteStream();
// 处理输入流
} else {
throw new IOException("Unexpected response code: " + response.code());
}
}
});
这些解决方法可以避免在getInputStream()上挂起Asynctask,并允许在后台进行网络请求和处理输入流。
