Java的HttpRequest类可以通过setDoOutput方法开启输出流,并通过输出流写入请求体内容。以下是一个设置请求体的示例代码: importjava.io.DataOutputStream;importjava.io.IOException;importjava.net.HttpURLConnection;importjava.net.URL;publicclassHttpRequestExample{publicstaticvoidmain(String[]args)throwsIOException{String...
首先,我们需要创建与服务器的HTTP连接。在Java中,可以使用HttpURLConnection类来实现这个功能。 importjava.net.HttpURLConnection;importjava.net.URL;publicclassHttpRequestExample{publicstaticvoidmain(String[]args){try{// 创建URL对象URLurl=newURL("// 打开连接HttpURLConnectionconnection=(HttpURLConnection)url....
import java.net.HttpURLConnection; import java.net.URL; public class HttpExample { public static void main(String[] args) throws IOException { URL url = new URL(\https://www.example.com\ HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod(\GET\...
net.HttpURLConnection; import java.net.URL; public class HttpRequestExample { public static void main(String[] args) { try { // 创建URL对象 URL url = new URL("https://www.example.com"); // 打开连接 HttpURLConnection connection = (HttpURLConnection) url.openConnection(); // 设置请求...
Java中,常用四种方式调用http请求外部接口 第一种:使用原生的Java网络编程(HttpURLConnection)- 不推荐 URL url =newURL("http://example.com/api"); HttpURLConnection connection=(HttpURLConnection) url.openConnection(); connection.setRequestMethod("GET");intresponseCode =connection.getResponseCode();if(...
三、使用 Okhttp 库 Okhttp 是由 Square 公司开发的一款轻量级网络请求库,支持普通的 HTTP/1.1 和 SPDY,可与 Retrofit 等网络请求框架搭配使用。 示例代码: importokhttp3.OkHttpClient;importokhttp3.Request;importokhttp3.Response;importjava.io.IOException;publicclassOkhttpExample{privatestaticfinalOkHttpClient...
前言在日常工作和学习中,有很多地方都需要发送HTTP请求,本文以Java为例,总结发送HTTP请求的多种方式HTTP请求实现过程:GET创建远程连接设置连接方式(get...
The following is an example of a GET request that prints the response body as a String: Copy HttpClient client = HttpClient.newHttpClient(); HttpRequest request = HttpRequest.newBuilder() .uri(URI.create("http://foo.com/")) .build(); client.sendAsync(request, BodyHandlers.ofString()...
