Java 标准库提供了HttpURLConnection类来实现 HTTP 请求。以下是一个简单的示例,用于发送 JSON 参数的 HTTP POST 请求。 2.1 示例代码 importjava.io.OutputStream;importjava.net.HttpURLConnection;importjava.net.URL;publicclassHttpPostExample{publicstaticvoidmain(String[]args){StringurlString="StringjsonInputSt...
private string HttpRequest(Dictionary<string, object> dic, string url) { string json = JSONhelper.ObjToJson(dic); WebRequest request = WebRequest.Create(url); request.Method = WebRequestMethods.Http.Post; request.ContentType = "application/json"; using (Stream requestStream = request.GetRequestS...
connection.setRequestProperty("Content-Type","application/json"); 1. 以上代码中,我们使用setRequestProperty方法设置请求头的键值对。在这个例子中,我们设置了Content-Type为application/json。 步骤3: 添加请求体 在发送POST请求时,通常需要将数据放在请求体中。以下是添加请求体的代码: StringrequestBody="{\"key...
URL url=newURL(httpUrl);//通过远程url连接对象打开连接connection =(HttpURLConnection) url.openConnection();//设置连接请求方式connection.setRequestMethod("POST");//设置连接主机服务器超时时间:15000毫秒connection.setConnectTimeout(150000);//设置读取主机服务器返回数据超时时间:60000毫秒connection.setReadTi...
