以下是使用Java发送from-data格式请求的示例代码:
```
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
public class FormDataExample {
public static void main(String[] args) {
String url = "https://example.com/api";
String charset = "UTF-8";
String param1 = "value1";
String param2 = "value2";
try {
// Create connection
URL apiURL = new URL(url);
HttpURLConnection connection = (HttpURLConnection) apiURL.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
connection.setDoOutput(true);
// Encode parameters and send request
String postData = "param1=" + URLEncoder.encode(param1, charset) +
"¶m2=" + URLEncoder.encode(param2, charset);
connection.getOutputStream().write(postData.getBytes(charset));
// Read response
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String response;
while ((response = reader.readLine()) != null) {
System.out.println(response);
}
reader.close();
} catch (Exception e) {
System.err.println("Error occurred: " + e.getMessage());
}
}
}
```
在此示例中,我们使用HttpURLConnection类创建一个POST请求,并将Content-Type设置为“application/x-www-form-urlencoded”,这是from-data格式的一种常见变体。我们然后将参数编码为字符串,并将其写入连接的输出流中。最后,我们读取响应并在控制台上打印它。
