调用微信支付沙箱环境的API接口验证（ruby）

由于2018年5月29日微信支付HTTPS服务器更换证书&＃xff0c;为了检查服务器是否支持了DigiCert的证书&＃xff0c; 特地手动些了以下验证方法&＃xff1a;

def sign_generate(params)

key &＃61; params.delete(:key)

query &＃61; params.sort.map do |key, value|
"#{key}&＃61;#{value}" if value !&＃61; "" && !value.nil?
end.compact.join(&＃39;&&＃39;)

Digest::MD5.hexdigest("#{query}&key&＃61;#{key || WxPay.key}").upcase
end

params &＃61; {}
params[:appid ] &＃61; WX_APP_ID
params[:key] &＃61; WX_API_KEY
params[:mch_id] &＃61; WX_MCH_ID
params[:nonce_str] &＃61; &＃39;weixinpay&＃39;&＃43; "#{Time.now.to_i}" &＃43; "str"

sign &＃61; sign_generate(params)
payload &＃61; "#{params.map { |k, v| "<#{k}>#{v}" }.join}#{sign}"

url &＃61; "https://apitest.mch.weixin.qq.com/sandboxnew/pay/getsignkey"
r &＃61; RestClient::Request.execute(
{
method: :post,
url: url,
payload: payload,
headers: { content_type: &＃39;application/xml&＃39; }
}
)

result &＃61; Hash.from_xml(r)
hash &＃61; {}

if result[&＃39;xml&＃39;].class &＃61;&＃61; Hash
result[&＃39;xml&＃39;].each_pair do |k, v|
hash[k] &＃61; v
end
end

p hash

如果返回的值为&＃xff1a;  {"return_code"&＃61;>"SUCCESS", "return_msg"&＃61;>"ok", "sandbox_signkey"&＃61;>"xxxxxx"}

恭喜你&＃xff0c; 你的验证通过了。
