You'll need to check your code to make sure you set the Netty options correctly and pass the correct host and port
could remote
Suggest a more specific description of the problem, what effect is to be achieved, what problems are encountered, and post the relevant code
The specific problem is a little more detailed, and there is no error information in your screenshot, can not judge
the network is connected
The following answers are based on ChatGPT and GISer Liu:
If you have written test cases in Android io, but do not send requests to the server while testing, there are several common problems that can cause this problem:
Check that your network connection is normal. You may want to check that your device or emulator is connected to the network and that your network connection is working. If your device is unable to connect to the Internet, you may need to change your network connection Settings or restart the device.
Check that your code is correct. You need to ensure that the request URL, request method, and request parameters are set correctly in the test case. If your code has syntax errors or logical errors, the test case may not work properly.
Check that your server is running. You need to make sure that the server is running and that your test cases can connect to it. You can test the API using a browser or other tool to make sure it works.
Check that your code handles the response correctly. If your code doesn't handle the server's response correctly, you may not see the results you expect. You need to check your code to make sure it parses the response correctly and converts it into the format you need.
There are many reasons why your Android application may not connect to the server. Here are some common reasons:
Network connection problems: Your device cannot connect to the Internet. Check that your Internet connection is working, and make sure your device can connect to other sites or services.
Server connection problems: Your server cannot connect or is down. You can use the command line or browser to try to connect to the server and see if you can connect to the server.
Network Proxy issues: If your application runs on an enterprise network, you may need to configure a network proxy. Please check that your network Settings are configured correctly.
Firewall issues: The firewall on your network or device may prevent applications from connecting to the server. Check the firewall Settings on your network or device to make sure your application can connect to the server.
Application code problems: If there is an error in the application code, it may prevent the application from connecting to the server. Please check your application code and make sure it can connect to the server properly.
If you are sure that none of the above reasons are the problem, you can check your application logs or debug messages to see if there are any errors or exceptions. You can also use a network debugging tool, such as Charles or Fiddler, to check the communication between your application and the server.
Here is a sample code for sending a POST request in Android io using the OkHttp library:
// 创建OkHttpClient对象
OkHttpClient client = new OkHttpClient();
// 创建JSON数据请求体
JSONObject jsonBody = new JSONObject();
try {
jsonBody.put("username", "testuser");
jsonBody.put("password", "testpassword");
} catch (JSONException e) {
e.printStackTrace();
}
RequestBody body = RequestBody.create(MediaType.parse("application/json"), jsonBody.toString());
// 创建POST请求
Request request = new Request.Builder()
.url("http://example.com/api/login")
.post(body)
.build();
// 发送请求并处理响应
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()) {
throw new IOException("Unexpected code " + response);
}
String responseBody = response.body().string();
Log.d(TAG, responseBody);
}
});
In the above code, we first create an OkHttpClient object. Next, a JSON data Request body is created and a Request object is created using the POST method. The Request object is then sent through the OkHttpClient object and the result of the response is processed. In this example, the enqueue() method provided by the OkHttp library is used to send requests asynchronously to avoid time-consuming network operations in the main thread. In the onResponse() callback method, you get the response returned by the server.
Write based on Monster group and GPT:
Code error: Check the code and whether the correct methods were called, request parameters, etc.
Network problems: The network connection is normal, including whether it is connected to the correct WiFi, whether the proxy is set, whether the VPN is enabled, and so on. You can test on another network, or try testing on another device on the same network.
Server problem: Is the server running properly?
