JAVA为response设置请求头Content-Type示例

JAVA为response设置请求头Content-Type示例代码如下:
```java
import javax.servlet.http.HttpServletResponse;
public class Example {
public static void main(String[] args) {
HttpServletResponse response = ...; // 获取HttpServletResponse对象
response.setContentType("application/json");
}
}
```
以上代码演示了如何使用HttpServletResponse对象设置HTTP响应头中的Content-Type。在这个例子中,我们使用response.setContentType("application/json")指定了响应头中的Content-Type为application/json。

java http请求头设置Content-type 且字符集为utf-8
可以通过设置请求头的方式来设置Content-type和字符集,示例代码如下:
```
url = "http://example.com"
payload = "{\"key\": \"value\"}"
headers = {
'Content-Type': 'application/json; charset=utf-8'
}
response = requests.post(url, data=payload, headers=headers)
```
其中,`Content-Type`设置的是`application/json`,表示请求体内容的类型是JSON格式,字符集使用UTF-8编码。
java 发送一个post请求 用form-data格式 请求头的requestType-Content设置为ModelingStand
ard
可以使用Java的HttpURLConnection类来发送POST请求,并设置请求头为ModelingStandard。以下是示例代码:
```java
import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
public class PostFormDataExample {
public static void main(String[] args) throws IOException {
// 设置请求URL
URL url = new URL("https://example.com/api");
// 创建连接对象
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
// 设置请求头
conn.setRequestProperty("requestType-Content", "ModelingStandard");
// 设置请求正文
String requestBody = "name=John&age=30";
conn.setDoOutput(true);
try (OutputStream os = conn.getOutputStream()) {
byte[] input = requestBody.getBytes("utf-8");
os.write(input, 0, input.length);
}
// 发送请求并获取响应
int responseCode = conn.getResponseCode();
System.out.println("Response Code: " + responseCode);
try (BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(), "utf-8"))) {
StringBuilder response = new StringBuilder();
String responseLine = null;
while ((responseLine = br.readLine()) != null) {
response.append(responseLine.trim());
}
System.out.println("Response Body: " + response.toString());
}
}
}
```
