客戶端POST發送json數據給服務端
//請求的地址
String url = "http://localhost:8080/springmvc/request/postRequest";
//創建Http Request(內部使用HttpURLConnection)
ClientHttpRequest request =
new SimpleClientHttpRequestFactory().
createRequest(new URI(url), HttpMethod.POST);
//設置請求頭的內容類型頭和內容編碼（GBK）
request.getHeaders().set("Content-Type", "application/json;charset=gbk");
//以GBK編碼寫出請求內容體
String jsonData = "{\"username\":\"admin\", \"password\":\"admin\"}";
request.getBody().write(jsonData.getBytes("gbk"));
//發送請求並得到響應
ClientHttpResponse response = request.execute();
System.out.println(response.getStatusCode());
客戶端接收服務器端json數據響應
public static void jsonRequest() throws IOException, URISyntaxException {
//請求的地址
String url = "http://localhost:8080/springmvc/response/reponseContent";
//創建Http Request(內部使用HttpURLConnection)
ClientHttpRequest request =
new SimpleClientHttpRequestFactory().
createRequest(new URI(url), HttpMethod.POST);
//設置客戶端可接受的媒體類型
request.getHeaders().set("Accept", "application/json");
//發送請求並得到響應
ClientHttpResponse response = request.execute();
//得到響應體的編碼方式
Charset charset = response.getHeaders().getContentType().getCharSet();
//得到響應體的內容
InputStream is = response.getBody();
byte bytes[] = new byte[(int)response.getHeaders().getContentLength()];
is.read(bytes);
String jsonData = new String(bytes, charset);
System.out.println("charset : " + charset + ", json data : " + jsonData);
}
