准备:
1,导入微信的libs包libammsdk.jar;
2,测试时使用weixinDemo中的debug_keystore;
3,需要注意应用要通过审核,并且几个Key值正确,一下为微信支付Demo中的值:

==========================================
根据微信支付Demo,微信支付分为三步:
第一步,获取accessToken,accessToken值第二步要用;

字段生成方法//package生成方法：//A)对所有传入参数按照字段名的ASCII
码从小到大排序（字典序）后，使用URL 键值对的格式（即key1=value1&key2=value2…）拼接成字符串string1；//B)
在string1 最后拼接上key=partnerKey 得到stringSignTemp 字符串， 并对 stringSignTemp进行md5 运算，再将得到的字符串所有字符转换为大写，得到sign值signValue。//C)对string1
中的所有键值对中的value 进行urlencode 转码，按照a 步骤重新拼接成字符串，得到string2。对于js 前端程序，一定要使用函数encodeURIComponent 进行urlencode编码（注意！进行urlencode时要将空格转化为%20而不是+）。//D)将sign=signValue
拼接到string1 后面得到最终的package 字符串。//app_signature生成方法：//A）参与签名的字段包括：appid、appkey、noncestr、package、timestamp以及
traceid //B）对所有待签名参数按照字段名的ASCII
码从小到大排序（字典序）后，使用URL 键值对的格式（即key1=value1&key2=value2…）拼接成字符串string1。 注意：所有参数名均为小写字符//C）对string1
作签名算法，字段名和字段值都采用原始值，不进行URL 转义。具体签名算法为SHA1</p> |
