課金のAPIが欲しいとか作ってみたとか、途中経過とか

七夕のお願い
課金API
必要な物
aws sdk for java (1.2.1使った)
それに付いてる3rdpartyの中身 (多分httpClientしか使ってない)

使い方はActivityClient.java のmainに書いてあり

githubにあげるのもめんどいからここにコピペ

MailPassAWSCredentials.java

package jp.jawsug.account;

import com.amazonaws.auth.AWSCredentials;

public class MailPassAWSCredentials implements AWSCredentials {

    private String mailAddress;

    private String password;

    public MailPassAWSCredentials(String mail, String pass) {
        this.mailAddress = mail;
        this.password = pass;
    }

    @Override
    public String getAWSAccessKeyId() {
        return this.mailAddress;
    }

    @Override
    public String getAWSSecretKey() {
        return this.password;
    }
}

ActivityClient.java

ここが大事な所。
