java - 如何使用 Java 上的 Selenium WebDriver 从 json 调用(Post、Get、JSON)中获取任何值？

Question

我有以下功能:我通过用户表单创建一个新用户。在我提交输入的数据后，创建的用户获取条形码，该条形码将用于通过手动扫描仪扫描该条形码来访问其他系统部分。那么我怎样才能通过Java上的Selenium WebDriver获得任何值(在我的例子中，来自json调用(Post、Get、JSON)的条形码？

Selenium 与 json 无关。您可以使用Apache HttpClient 库发送GET、POST、PUT 和DELETE 请求并接收响应。下面给出的是适用于所有情况的简化函数。

public static HttpResponse sendRequest(String requestType, String body,String url,
        String... headers) throws Exception {
    try {

        HttpGet getRequest = null;
        HttpPost postRequest;
        HttpPut putRequest;
        HttpDelete delRequest;
        HttpResponse response = null;
        HttpClient client = new DefaultHttpClient();

        // Collecting Headers
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        for (String arg : headers) {

//Considering that you are applying header name and values in String format like this "Header1,Value1"

            nvps.add(new BasicNameValuePair(arg.split(",")[0], arg
                    .split(",")[1]));
        }
        System.out.println("Total Headers Supplied " + nvps.size());

        if (requestType.equalsIgnoreCase("GET")) {
            getRequest = new HttpGet(url);
            for (NameValuePair h : nvps) {
                getRequest.addHeader(h.getName(), h.getValue());
            }
            response = client.execute(getRequest);
        }

        if (requestType.equalsIgnoreCase("POST")) {
            postRequest = new HttpPost(url);
            for (NameValuePair h : nvps) {
                postRequest.addHeader(h.getName(), h.getValue());       
            }

            StringEntity requestEntity = new StringEntity(body,"UTF-8");
            postRequest.setEntity(requestEntity);
            response = client.execute(postRequest);
        }

        if (requestType.equalsIgnoreCase("PUT")) {
            putRequest = new HttpPut(url);
            for (NameValuePair h : nvps) {
                putRequest.addHeader(h.getName(), h.getValue());
            }
            StringEntity requestEntity = new StringEntity(body,"UTF-8");
            putRequest.setEntity(requestEntity);
            response = client.execute(putRequest);
        }

        if (requestType.equalsIgnoreCase("DELETE")) {
            delRequest = new HttpDelete(url);
            for (NameValuePair h : nvps) {
                delRequest.addHeader(h.getName(), h.getValue());
            }
            response = client.execute(delRequest);
        }

        return response;

    } catch (Exception e) {
        e.printStackTrace();
        throw e;
    }
}
