/listFilm?page=1&areaId=906&filmTypeId=1 微信app支付 签名错误 以及 访问https 的解决办法微信支付的接口不同于支付宝等其他第三方接口足够友好，所以这里有必要对 微信签名错误和访问https接口做一些小结以供参考。签名错误：
首先总结原因，可能发生签名错误的原因如下： 1 密钥错误，密钥是32位长的一串字符，类似于 f0fnf5872825aien55end044e092le39 ，如果需要重新设置 ，位置在 设置位置：账户设置-安全设置-API安全 2 本地签名程序
基本遵照微信官方文档说明即可 https://pay./wiki/doc/api/app.php?chapter=4_3传递哪些参数 需要根据文档说明 https://pay./wiki/doc/api/app.php?chapter=9_1参考(内部的一些关键参数只提供参考，位数不对)： sb
appid=wxf6e555f&body=Corsair Neutron Series GTX 480GB 固态硬盘&mch_id=1&nonce_str=1BF9DEA12 &notify_url=/pay/notify&out_trade_no =857821&spbill_create_ip=10.244.1.171&total_fee=84462&trade_type=APP&key=f0fn3fen55end044e092le39 再对此字符串进行md5加密之后调成大写，即为sign签名 生成的xml文档：&xml&&appid&wxf6e555f&/appid&&body&&![CDATA[Corsair Neutron Series GTX 480GB 固态硬盘]]&&/body&&mch_id&1&/mch_id&&nonce_str&1BF9DEA12&/nonce_str&&notify_url&/pay/notify&/notify_url&&out_trade_no&857821&/out_trade_no&&sign&&![CDATA[CD0DCCA447A6C0BA545A0BA]]&&/sign&&spbill_create_ip&10.244.1.171&/spbill_create_ip&&total_fee&84462&/total_fee&&trade_type&APP&/trade_type&&/xml&生成的xml是提交给 微信的参数，必须和签名的字符串里的值相同 如果返回的微信参数提示 签名错误，可以到微信官方测试测试地址测试https://pay./wiki/tools/signverify/ 微信返回信息中，如果出现签名错误，可以把自己的资料填写在上面的测试用例中获取微信生成的签名， 如果测试sign与自己生成的不同 返回上步检查，如果微信生成的和自己生成的签名相同，但是微信还是返回签名错误，则一定是商品中文(body)编码。 有几个地方的编码必须注意. 设置 sb
字符串 的时候 body一定为utf-8,sb字符串md5加密的时候 必须为utf-8, 传递给 微信的时候 ，此参数也必须为 utf-8 :entity = new StringEntity(xml,"utf-8");httpclient 头部和参数 也设置成utf-8:httpPost.setEntity(entity);
httpPost.addHeader("Content-Type", "text/charset=UTF-8");
httpClient.getParams().setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET, "UTF-8");httpPost.getParams().setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET, "UTF-8"); 这几个编码优先级逐步提高，也就是说后面的会覆盖前面的。

微信支付中文签名错误
最近因为公司需要，要做一个微信支付，碰到一个签名的问题。 折腾了我两天，郁闷呀
1、先说一下，签名的问题，按照规则排序就不说了，最后说一下编码 &
data=new String( data.getBytes( "UTF-8"),"ISO8859-1" );&
2、第二个是重点
这个也是对的，关键是这个改完了，还签名错误 最奇葩的是junit 单元测试时过了的，但是 在生产环境中，就是有问题。然后就是各种折腾，首先还是测试，把中文换掉，OK的，说明还是编码的问题。然后再检查httpclient ，提交时候的编码，各种比对，问题以后。后来发现，在没有提交的时候，签名已经有问题了，比对内容，UE,然后人眼比对，各种无奈呀，最后，直接两个str equals，居然是true ,然后傻脸了，最后就是想tomcat 和junit 有什么不同，既然是java ,那么默认的肯定是UTF-8,一个噢然的机会，撇了一个签名函数 Md5 签名的参数是 byte ,需要把 String 转为byte ,然后就改了.getBytes("UTF-8") ，然后就OK了 ，后来就像这个问题。
在junit &下 str.getBytes()==str.getBytes("UTF-8")
在tomcat7 下str.getBytes()==str.getBytes("GBK"),
tomcat 版本是 7 &&
不是说java 默认下都是UTF-8 么，为什么会这样呢？
