在Java中,发送HTTP请求通常会涉及到使用`java.net.HttpURLConnection`、`java.net.URL`,或者是第三方库如`org.apache.httpcomponents.client5`等。当你需要在URL中包含引号或其他特殊字符时,你需要对它们进行正确的转义。下面是一个基本的例子,展示了如何使用`HttpURLConnection`发送GET请求,其中包含了查询字符串中有引号的情况:
```java
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class HttpRequestExample {
public static void main(String[] args) throws Exception {
String url = "https://api.example.com/search?q= \"John Doe\""; // URL with quotes escaped as %22
try (HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection()) {
connection.setRequestMethod("GET");
connection.setRequestProperty("Accept", "application/json");
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuilder response = new StringBuilder();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
System.out.println(response.toString());
} else {
System.out.println("Failed : HTTP error code : " + responseCode);
}
}
}
}
```
在这个例子中,我们使用`%22`来替换双引号`"`, 这是URL编码的方式。如果你使用的是其他的字符,例如空格,也需要相应的编码。
