谷歌安全浏览查找的java API代码

Question

我在编程中遇到了一些困难，并且请求体的含义混淆了。它总是返回400个响应代码。请帮帮我。

 String baseURL="https://sb-ssl.google.com/safebrowsing/api/lookup";
 String arguments = "";
 arguments+=URLEncoder.encode("client", "UTF-8")+"="+URLEncoder.encode("demo-app", "UTF-8")+"&";
 arguments+=URLEncoder.encode("apikey", "UTF-8")+"="+URLEncoder.encode("apikey", "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")+"&";
 arguments+=URLEncoder.encode("post_req_body", "UTF-8")+"="+URLEncoder.encode("2nhttp://www.google.comnhttp://www.facebook.com", "UTF-8");
 String query = arguments;
    System.out.println("Sending POST request - " + query);
// Construct the url object representing cgi script
    URL url = new URL( baseURL );
    // Get a URLConnection object, to write to POST method
    URLConnection connect = url.openConnection();
    // Specify connection settings
    connect.setDoInput(true);
    connect.setDoOutput(true);
// Get an output stream for writing
    OutputStream output = connect.getOutputStream();

    PrintStream pout = new PrintStream (output);
    pout.print ( query );
    pout.close();

您的请求是错误的。如果你使用POST请求，那么参数client、apikey、apiver和pver应该是URL的一部分。

请求体应该只包含要检查的url(加上第一行的url数)。

可以是这样的

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("12341234", "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);
// 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();
