java - 使用参数调用 POST 方法时无法获得正确的响应

Question

尝试使用 main 方法调用 post 方法，但收到 400 Bad request。我正在使用下面的代码

private static String POST_URL = "http://localhost:8080/RestApi/api/v1/getDetails";

public static void main(String[] args) {
    try {
        sendPost();
    } catch (Exception e) {
        System.out.println("Exception occurred while calling service and exception is " + e);
    }
}

private static void sendPost() throws Exception {
    HttpPost post = new HttpPost(POST_URL);
    post.addHeader(HttpHeaders.CONTENT_TYPE, "application/json");

    // add request parameter, form parameters
    List<NameValuePair> urlParameters = new ArrayList<>();
    urlParameters.add(new BasicNameValuePair("id", "1004906799"));
    urlParameters.add(new BasicNameValuePair("identifer", "Customer"));

    post.setEntity(new UrlEncodedFormEntity(urlParameters));

    try (CloseableHttpClient httpClient = HttpClients.createDefault(); CloseableHttpResponse response = httpClient.execute(post)) {

        System.out.println(EntityUtils.toString(response.getEntity()));
    }

}

Answer 1

尝试设置编码。将 post.setEntity(new UrlEncodedFormEntity(urlParameters)); 行替换为

post.setEntity(new UrlEncodedFormEntity(urlParameters, "UTF-8"));

尚未运行，但应该可以工作。
