Xml 收到Payezy/Firstdata无效签名

我目前正在开发一个使用Payezy/firstdata进行支付的网站。集成起来很麻烦，因为他们的API文档有点弱

我正在使用ColdFusion和cfhttp请求。我一直在按照以下步骤计算我的内容摘要和hmac哈希：

我最终得到了与演示终端中计算出的哈希值相匹配的哈希值，但是我的问题是：我在发送请求时遇到了一个奇怪的错误。我得到一个错误：

“收到无效签名‘Fgx/lR’。”

其中前几个字符每次都会更改。以下是我的请求代码：

邮费= 密钥id、hmac值、内容摘要都经过测试，都是正确的 x_time=GetIsTimeString（现在（））

提交的xml（不带空格或新行）

#确切身份证#
#密码#
#表格x\u卡片\u编号#
#FORM.x#u名字##FORM.x#u姓氏#
00
#表格x\U exp\U日期#
#数量#
#表格x_地址#
#FORM.x_city#
#FORM.x_zip#

我已将授权头更改为“Payezy_Gateway_API#key_id#：：#hmac_value#”，并且在Payezy终端上多次测试所使用的hmac值和密钥id时，我收到错误“Bad authorization header”

请，非常感谢您的帮助

在您链接的支持页面上使用示例Python代码进行测试时，CGGE4_API和GGE4_API对我都有效，但我拨打了他们的支持电话，他们告诉我应该使用GGE4_API

显然，支持页面已经过时，使用Payezy_Gateway_API根本不起作用。下面是该页面上的示例Python代码的外观：

从hashlib导入sha1
从时间导入gmtime，strftime
导入base64
进口hmac
导入httplib
payezy_gateway_date=strftime（“%Y-%m-%dT%H:%m:%S”，gmtime（））+Z”
uri='/transaction/v19'
key_id=“”#在此处添加您的密钥id
key=''#在此处添加您的HMAC密钥
事务_body=''#在此处添加事务请求正文
方法='POST'
content\u digest=sha1（事务\正文）.hexdigest（）
content_type='text/xml'#如果您使用的是json，则将其更改为'application/json'
主机='api.demo.globalgatewaye4.firstdata.com'
标题={'Content Type'：内容类型，
“x-gge4-content-sha1”：内容摘要，
“x-gge4-date”：Payezy_网关_日期，
‘授权’：‘GGE4_API’+密钥id+’：‘+base64.b64encode（hmac.new（密钥、方法+“\n”+内容类型+“\n”+内容摘要+“\n”+Payezy_网关\u日期+“\n”+uri.split（“？”）[0]，sha1.digest（））}
conn=httplib.HTTPSConnection（主机）
conn.request（方法、uri、事务体、头）
打印连接getresponse（）.read（）

---

在我的申请中，我还收到了收到的无效签名。原来我是在我的

内容类型

标题中添加

charset=utf-8

（归功于）。删除它使我的请求被接受。

我还试图用Payezy解决这个问题。我可能晚了一天，还缺了一美元，不过我还是要把这件事做好。我对我遇到的问题和/或尼克的原始代码做了几处修改：

删除事务xml中的字符集声明

将“文本”更改为“应用程序”

为了使加密与网站的测试加密相匹配，我将回车改为

char（10）

，然后

将第一个标题条目从“CGGE4_API”更改为“GGE_API”

仅供参考，如果您使用的是v11，您不需要任何头或散列代码，只需要xml

这是我的全部测试代码，包括一些分解返回的xml的代码

只是猜测，但您的计算中是否包含字符集？IIRC，cfhttp默认添加“UTF-8”。Payezy文档说，“如果内容类型标题中包含字符集，那么在计算中也必须使用它（计算器中没有这方面的规定）”。这可能是个问题。您可以使用Fiddler查看它正在发送什么，或者如果发送失败，请将cfhttp指向服务器上的.cfm页面，该页面会转储

GetHTTPRequestData（）

。此外，您确定它是“CGGE4_API”吗？一些示例使用了“GGE4_API”。不确定哪个是正确的。是的，我已经在上测试了python和C#示例。由于它们都有效，这表明cfhttp头中的文本前缀或额外字符集存在问题，但没有询问者的确认，这似乎不足以作为答案发布
