如何用Java调用别人API接口

java发一个http请求过去,带上参数就可以了啊,跟我们在浏览器上访问资源是一样的 只是它返回的是json格式的数据而已

给你两个方法吧:

public static String do_post(String url, ListNameValuePair name_value_pair) throws IOException {

String body = "{}";

DefaultHttpClient httpclient = new DefaultHttpClient();

try {

HttpPost httpost = new HttpPost(url);

httpost.setEntity(new UrlEncodedFormEntity(name_value_pair, StandardCharsets.UTF_8));

HttpResponse response = httpclient.execute(httpost);

HttpEntity entity = response.getEntity();

body = EntityUtils.toString(entity);

} finally {

httpclient.getConnectionManager().shutdown();

}

return body;

}

public static String do_get(String url) throws ClientProtocolException, IOException {

String body = "{}";

DefaultHttpClient httpclient = new DefaultHttpClient();

try {

HttpGet httpget = new HttpGet(url);

HttpResponse response = httpclient.execute(httpget);

HttpEntity entity = response.getEntity();

body = EntityUtils.toString(entity);

} finally {

httpclient.getConnectionManager().shutdown();

}

return body;

}

如何在java中调用api接口

需要导入对应的lib包,然后调用具体的接口以及方法

通过实现http协议进行post或者get请求具体api接口
