以下是将Java代码翻译成Python的代码:
```python
import urllib.request
import urllib.parse
username = "myUsername"
password = "myPassword"
url = "https://example.com/login.php"
query = urllib.parse.urlencode({'username': username, 'password': password}).encode('utf-8')
try:
loginUrl = urllib.request.urlopen(url + "?" + query)
response = loginUrl.read()
print(response.decode('utf-8'))
except Exception as e:
print(e)
```
这段Python代码使用了urllib库来发送GET请求,并将用户名和密码通过urlencode编码后作为查询字符串添加到URL中。如果登录成功,服务器应该向客户端发送一个响应,响应内容可以在控制台输出。请注意,此代码仅用于演示目的,并不是完整的生产就绪代码,您应该根据您的需求进行修改。

reader.readLine(); java.net.SocketException: Connection reset
根据提供的引用内容,java.net.SocketException: Connection reset错误通常是由于网络连接被重置而引起的。这种错误通常发生在使用HttpClient4进行网络请求时。解决这个问题的方法是检查网络连接是否正常,并确保服务器端正常响应。
以下是一个示例代码,演示如何处理java.net.SocketException: Connection reset错误:
```java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class HttpClientExample {
public static void main(String[] args) {
try {
URL url = new URL("http://example.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
StringBuilder response = new StringBuilder();
while ((line = reader.readLine()) != null) {
response.append(line);
}
reader.close();
System.out.println(response.toString());
} else {
System.out.println("HTTP request failed with response code: " + responseCode);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
```
这段代码使用HttpURLConnection发送GET请求,并读取服务器的响应。如果出现java.net.SocketException: Connection reset错误,可以尝试以下解决方法:
1. 检查网络连接是否正常,确保可以访问目标服务器。
2. 检查服务器端是否正常响应,可能是服务器端出现了问题导致连接被重置。
3. 尝试增加连接超时时间,可以使用`connection.setConnectTimeout(timeout)`设置连接超时时间。
java.lang.IllegalArgumentException: protocol = http host = null
这个异常通常是因为在使用Java请求HTTP时没有设置正确的URL或主机名导致的。请确保你的URL和主机名正确,并使用正确的协议(http或https)。
以下是一个示例代码,可以在Java中使用HttpURLConnection发送HTTP GET请求:
```java
import java.net.HttpURLConnection;
import java.net.URL;
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class HttpExample {
public static void main(String[] args) throws Exception {
URL url = new URL("https://example.com");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setRequestMethod("GET");
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer content = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
content.append(inputLine);
}
in.close();
System.out.println(content.toString());
}
}
```
这个示例代码向 "https://example.com" 发送了一个 HTTP GET 请求,并打印了响应的内容。请根据自己的实际情况修改URL和请求方法。
