在Java中发送HTTP请求通常有多种方式,每种都有其便捷性。以下是几个常用的库:
1. **Apache HttpClient**:这是一个老牌且功能丰富的HTTP客户端库,提供简单易用的API用于发送GET、POST等请求。
```java
CloseableHttpClient client = HttpClients.createDefault();
HttpGet httpGet = new HttpGet("http://example.com");
CloseableHttpResponse response = client.execute(httpGet);
```
2. **OkHttp**:这是一个流行的轻量级库,特别适合Android应用,API简洁直观。
```java
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("http://example.com")
.build();
Response response = client.newCall(request).execute();
```
3. **Java HttpURLConnection**:这是Java自带的标准库,虽然功能相对有限,但在不需要外部依赖的情况下可以使用。
```java
URL url = new URL("http://example.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
StringBuilder content = new StringBuilder();
while ((inputLine = in.readLine()) != null) {
content.append(inputLine);
}
```
每个库都有其优势,如性能、易用性和社区支持。选择哪种取决于项目需求和个人偏好。
