Java Http（application/x-www-form-urlencoded）post请求方式代码示例

CloseableHttpClient httpClient = HttpClients.createDefault();
try {
//创建一个获取连接客户端的工具
    URIBuilder builder = new URIBuilder(url);
//拼接url参数
    builder.addParameter("token","");
    URI uri = builder.build();
    //创建Post请求、设置请求类型
    HttpPost httpPost = new HttpPost(uri);
    httpPost.addHeader("Content-Type", "application/x-www-form-urlencoded");
//需要的参数
    Map<String,String> map = new HashMap<>();
    map.put("","");
    map.put("","");
    ...
    //拼接参数体
    List<NameValuePair> paramList=new ArrayList<NameValuePair>();
    for(Map.Entry<String, String> entry : map.entrySet()){
        paramList.add(new BasicNameValuePair(entry.getKey(),entry.getValue()));
    }
    httpPost.setEntity(new UrlEncodedFormEntity(paramList,"UTF-8"));

    try {
//发送请求
        CloseableHttpResponse response = httpClient.execute(httpPost);
        org.apache.http.HttpEntity httpEntity = response.getEntity();
//返回状态码200表示请求成功
        if (response.getStatusLine().getStatusCode() == 200) {
            JSONObject resultString = (JSONObject) JSONObject.parse(EntityUtils.toString(response.getEntity(), "UTF-8"));
            return Result.ok(JSONObject.toJSON(resultString));
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
} catch (URISyntaxException | UnsupportedEncodingException e) {
    e.printStackTrace();
}
