[英]How can i get any value from json calls (Post, Get, JSON) with Selenium WebDriver on Java?
I have a following functionality: I create through the user form a new user. 我具有以下功能:通过用户表单创建一个新用户。 After i had submitted the entered data, created user get the bar-code, which would be used for get access to the other system section by scanning that bar-code with hand-scanner.
在我提交了输入的数据之后,创建的用户将获得条形码,该条形码可通过使用手动扫描仪扫描该条形码来访问其他系统部分。 So how can i get any value (in my case that bar-code from json calls (Post, Get, JSON) with Selenium WebDriver on Java?
那么,如何在Java上使用Selenium WebDriver获取任何值(以json条形码(Post,Get,JSON)中的条形码为例)呢?
Selenium has nothing to do with json. Selenium与json无关。 You can use Apache HttpClient library for sending GET, POST, PUT and DELETE requests and receiving the responses.
您可以使用Apache HttpClient库发送GET,POST,PUT和DELETE请求并接收响应。 Given below is a simplified function for all cases.
下面给出的是所有情况下的简化功能。
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;
}
}
Selenium only deals with browsers. 硒仅与浏览器打交道。 Java has classes that do http requests.
Java具有执行http请求的类。
see the code below: 参见下面的代码:
private HttpURLConnection setODataConnection(String url, String method) {
try {
URL obj = new URL(url);
HttpURLConnection conn = (HttpURLConnection) obj.openConnection();
conn.setRequestMethod(method);
// add request header
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Accept", "application/json;odata=verbose");
return conn;
} catch (Exception e) {
Assert.fail(e.getMessage());
return null;
}
}
private StringBuilder sendODataRequest(HttpURLConnection conn) {
try {
int responseCode = conn.getResponseCode();
String method = conn.getRequestMethod();
System.out.println("\nSending '" + method + "' request to URL : " + conn.getURL());
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
StringBuilder response = new StringBuilder();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
return response;
} catch (Exception e) {
Assert.fail(e.getMessage());
return null;
}
}
private ArrayList<String> getByFullUrl(String fullUrl, String entity) {
HttpURLConnection conn = setODataConnection(fullUrl, "GET");
StringBuilder response = sendODataRequest(conn);
ArrayList<String> s = new ArrayList<String>();
Pattern p = Pattern.compile(entity + "\" : (.*?)\\}");
Matcher m = p.matcher(response);
while (m.find()) {
s.add(m.group(1).replace("\"", ""));
}
return s;
}
public ArrayList<String> get(String table, String entity) {
String url = oDataUrl + table + "?$select=" + entity;
return getByFullUrl(url, entity);
}
public void post(String table, String bodyDetails) {
String url = oDataUrl + table;
HttpURLConnection conn = setODataConnection(url, "POST");
conn.setDoOutput(true);
try {
DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
wr.writeBytes("details={" + bodyDetails + "}");
wr.flush();
wr.close();
} catch (Exception e) {
Assert.fail(e.getMessage());
}
sendODataRequest(conn);
}
public void put(String table, String id, String bodyDetails) {
String url = oDataUrl + table + "(" + id + ")";
HttpURLConnection conn = setODataConnection(url, "PUT");
conn.setDoOutput(true);
try {
DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
wr.writeBytes("details={" + bodyDetails + "}");
wr.flush();
wr.close();
} catch (Exception e) {
Assert.fail(e.getMessage());
}
sendODataRequest(conn);
}
