Java simulated HTTPS request

A recent app to use cloud storage, compared to a few cloud space, finally chose Bmob (http://www.bmob.cn/), Bmob features a lot, but also provides a variety of APIs, free.

Because my app is small and business is simple, the rest API provided directly with Bmob.

Bmob REST API is HTTPS protocol, so my idea is: Lead out Bmob certificate, use Java Keytool tool to make Certificate library (KeyStore), then use httpsurlconnection and Bmob server communication.

The following steps are specific:

1: Export Certificate
Use the IE Certificate tool to export the certificate of the Web site. Open the Web page, view the page's property page, the property page in the lower-right corner to find the certificate, and finally "copy the certificate to a file."



Because the Java Keytool tool cannot import certificates in the P7B format, in the Import Wizard, I select the BASE64-encoded CER certificate:


Finally get the certificate file:


2: Create the Certificate library and import the certificate
With the Java Keytool Tool, execute the following command to get the Bmob.keystore certificate library file:

--Generate Certificate library files
Keytool-genkey-alias bmob.keystore-keyalg rsa-validity 100000-keystore bmob.keystore

--Import Der/cer Certificate
Keytool-import-file Bmob.cer-keystore Bmob.keystore

Note: When importing a bmob.cer file into a certificate library, it is best to have the same directory as the certificate library

3:java Call Request
Static block Setting Certificate:

/** * * * *
 Load Certificate
 * * * *
/static {
	System.setproperty ("Javax.net.ssl.trustStore", "C:\\bmob.keystore");
	System.setproperty ("Javax.net.ssl.trustStorePassword", "password");
}

Post method:

/** * Add Example * @see <a href= ' Http://docs.bmob.cn/restful/developdoc/index.html?menukey=develop_doc&key=develop_ Restful#index_ Add Data ' > Example </a> */public static void Add () throws Exception {//build request URL PostURL = new URL (add_u

	RL); Httpsurlconnection con = (httpsurlconnection) posturl.openconnection ();//Open Connection Con.setrequestmethod ("POST");
	Post method commits con.setdooutput (TRUE);//Open Read-write properties, default is False Con.setdoinput (true);

	Con.setusecaches (false);//post request cannot use cache con.setinstancefollowredirects (TRUE);
	Add header information Con.setrequestproperty ("X-bmob-application-id", app_id);
	Con.setrequestproperty ("X-bmob-rest-api-key", Api_key);

	Con.setrequestproperty ("Content-type", "Application/json");

	DataOutputStream out = new DataOutputStream (Con.getoutputstream ());
	Send request String data = "{\" name\ ": \" Tom\ "}";
	Out.writebytes (data);
	Out.flush ();

	Out.close ();
	Receive data BufferedReader reader = new BufferedReader (New InputStreamReader (Con.getinputstream (), "UTF-8"));
	String Line; StringbuffEr responsetext = new StringBuffer ();
	while (line = Reader.readline ())!= null) {Responsetext.append (line). Append ("\ r \ n");
	} reader.close ();
	Con.disconnect ();
System.out.println (Responsetext.tostring ()); }

Get Way:

/** * Query Data example * @see <a target=_blank href= "http://docs.bmob.cn/restful/developdoc/index.html?menukey=develop_doc& Amp;key=develop_restful#index_ query Data "> Example </a> * * */public static void Select () throws Exception {//Build request URL Post

	url = new URL (select_url);
	Httpsurlconnection con = (httpsurlconnection) posturl.openconnection ();//Open Connection Con.setrequestmethod ("get");//get method Commit
	Con.setdoinput (TRUE);

	Con.setinstancefollowredirects (TRUE);
	Add header information Con.setrequestproperty ("X-bmob-application-id", app_id);
	Con.setrequestproperty ("X-bmob-rest-api-key", Api_key);

	Con.setrequestproperty ("Content-type", "Application/json");
	Receive data BufferedReader reader = new BufferedReader (New InputStreamReader (Con.getinputstream (), "UTF-8"));
	String Line;
	StringBuffer responsetext = new StringBuffer ();
	while (line = Reader.readline ())!= null) {Responsetext.append (line). Append ("\ r \ n");
	} reader.close ();
	Con.disconnect ();
System.out.println (Responsetext.tostring ()); }

In fact, the same as the HTTP request, but more than the Certificate Production section.
