我正在尝试通过Google的安全浏览API发送请求,但我没有得到任何输出,我不知道为什么。我在网上搜索了这个,但是每个解决方案或者只是指如何发送或接收POST请求(但不是两者),或者数据的输入是以不同方式完成的。
根据Google安全浏览文档:
使用以下格式在POST请求正文中指定查询的URL:
POST_REQ_BODY = NUM LF URL (LF URL)* NUM = (DIGIT)+ URL = URL string following the RFC 1738
-
回复机构:
POST_RESP_BODY = VERDICT (LF VERDICT)* VERDICT = “phishing” | “malware” | "unwanted" | “phishing,malware” >| "phishing,unwanted" | "malware,unwanted" | "phishing, malware, unwanted" >| “ok”
并发送至:
https://sb-ssl.google.com/safebrowsing/api/lookup?client=CLIENT&key=APIKEY
我找到另一个主题,显示您如何发送此请求,但我不确定如何获取/打印响应。这是我试过的:
String baseURL="https://sb-ssl.google.com/safebrowsing/api/lookup";
String arguments = "";
arguments +=URLEncoder.encode("client", "UTF-8") + "=" + URLEncoder.encode("myapp", "UTF-8") + "&";
arguments +=URLEncoder.encode("apikey", "UTF-8") + "=" + URLEncoder.encode("12345", "UTF-8") + "&";
arguments +=URLEncoder.encode("appver", "UTF-8") + "=" + URLEncoder.encode("1.5.2", "UTF-8") + "&";
arguments +=URLEncoder.encode("pver", "UTF-8") + "=" + URLEncoder.encode("3.0", "UTF-8");
// Construct the url object representing cgi script
URL url = new URL(baseURL + "?" + arguments);
// Get a URLConnection object, to write to POST method
URLConnection connect = url.openConnection();
// Specify connection settings
connect.setDoInput(true);
connect.setDoOutput(true);
InputStream input = connect.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
StringBuilder result = new StringBuilder();
String line;
// Get an output stream for writing
OutputStream output = connect.getOutputStream();
PrintStream pout = new PrintStream (output);
pout.print("2");
pout.println();
pout.print("http://www.google.com");
pout.println();
pout.print("http://www.facebook.com");
pout.close();
while((line = reader.readLine()) != null) {
result.append(line);
}
System.out.println(result.toString());
错误在哪里?
答案 0 :(得分:1)
移动以下行:
InputStream input = connect.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
在pout.close();
之后,getInputStream
方法实际上将HTTP请求发送到服务器,在该示例中,您在填充正文之前发送请求。
看起来在此之后还有其他事情需要解决。
