作为一个快速背景：我已经成功建立了一个小型应用程序，该应用程序将连接到雅虎的API并使用我团队名单上的PUT请求每天设置我的阵容Yahoo Developer's Guide。
具体来说，我现在遇到问题：
POST
使用POST，可以从团队中添加和/或删除玩家，或进行交易 可以提出。 POST到事务集合的URI是：
http://fantasysports.yahooapis.com/fantasy/v2/league//transactions对事务API的POST请求的输入XML格式 用一个团队中的另一个玩家替换一个玩家是：
<fantasy_content> <transaction> <type>add/drop</type> <players> <player> <player_key>{player_key}</player_key> <transaction_data> <type>add</type> <destination_team_key>{team_key}</destination_team_key> </transaction_data> </player> <player> <player_key>{player_key}</player_key> <transaction_data> <type>drop</type> <source_team_key>{team_key}</source_team_key> </transaction_data> </player> </players> </transaction> </fantasy_content>
我提出请求的方法如下：
def self.make_signed_request(address, method, user_id, input_file=nil )
# format http method and return false if not accepted API method
method = method.upcase
return false if ( method != "GET" ) && ( method != "POST" ) && ( method != "PUT")
# find user
user = User.find(user_id)
if ( user.yahoo_access_token_expiration.nil? || user.yahoo_access_token_expiration < Time.now )
# expired token, so renew
YahooOAuth.renew_token(user_id)
user.reload
end
# normalize text HMAC-SHA1
digest = OpenSSL::Digest.new('sha1')
nonce = rand(10 ** 30).to_s.rjust(30,'0')
timestamp = Time.now.to_i
text = method + "&" + CGI.escape("#{address}") + "&" + CGI.escape("oauth_consumer_key=#{YAHOO_OAUTH_API[:CLIENT_ID]}&oauth_nonce=#{nonce}&oauth_signature_method=HMAC-SHA1&oauth_timestamp=#{timestamp}&oauth_token=#{CGI.escape(user.yahoo_access_token)}&oauth_version=1.0")
# create key for HMAC-SHA1
key = CGI.escape("#{YAHOO_OAUTH_API[:CLIENT_SECRET]}")+ "&" + CGI.escape("#{user.yahoo_access_token_secret}")
# create HMAC-SHA1 signature for api request
hmac = OpenSSL::HMAC.digest(digest, key, text)
signature_sha1 = CGI.escape(Base64.strict_encode64(hmac))
# make API request
response = nil
if method == "GET"
response = Curl.get("#{address}?oauth_consumer_key=#{YAHOO_OAUTH_API[:CLIENT_ID]}&oauth_nonce=#{nonce}&oauth_signature_method=HMAC-SHA1&oauth_timestamp=#{timestamp}&oauth_token=#{CGI.escape(user.yahoo_access_token)}&oauth_version=1.0&oauth_signature=#{signature_sha1}")
elsif method == "POST"
# return "Not implemented"
response = Curl.post("#{address}?oauth_consumer_key=#{YAHOO_OAUTH_API[:CLIENT_ID]}&oauth_nonce=#{nonce}&oauth_signature_method=HMAC-SHA1&oauth_timestamp=#{timestamp}&oauth_token=#{CGI.escape(user.yahoo_access_token)}&oauth_version=1.0&oauth_signature=#{signature_sha1}", input_file) do |http|
http.headers['Accept'] = 'application/xml'
http.headers['Content-Type'] = 'application/xml'
end
elsif method == "PUT"
response = Curl.put("#{address}?oauth_consumer_key=#{YAHOO_OAUTH_API[:CLIENT_ID]}&oauth_nonce=#{nonce}&oauth_signature_method=HMAC-SHA1&oauth_timestamp=#{timestamp}&oauth_token=#{CGI.escape(user.yahoo_access_token)}&oauth_version=1.0&oauth_signature=#{signature_sha1}", input_file) do |http|
http.headers['Accept'] = 'application/xml'
http.headers['Content-Type'] = 'application/xml'
end
end
# return raw XML result
return response.body
end
当我提出要求时 -
def add_drop(players)
# players are added in [{player_key}, {add/drop}, {faab_bid (or nil if not FAAB)}] form
url = "http://fantasysports.yahooapis.com/fantasy/v2/league/#{self.league.league_key}/transactions"
builder = Nokogiri::XML::Builder.new(:encoding => 'UTF-8') do |xml|
xml.fantasy_content {
xml.transaction {
xml.type "add/drop"
xml.faab_bid players[0][2] unless players[0][2].nil?
xml.players {
players.each do |player|
xml.player {
xml.player_key player[0]
xml.transaction_data {
xml.type player[1] # this will be "add" or "drop"
# adds use "destination_team_key," drops use "source_team_key"
if player[1] == "add"
xml.destination_team_key self.team_key
else
xml.source_team_key self.team_key
end
} # transaction_data
} # player
end
} # players
} # transaction
} # fantasy_content
end # builder
xml_input = builder.to_xml
YahooOAuth.make_signed_request(url, 'put', self.user.id, xml_input)
end
- 生成的XML如下所示 -
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<fantasy_content>\n <transaction>\n <type>add/drop</type>\n <players>\n <player>\n <player_key>357.p.10171</player_key>\n <transaction_data>\n <type>add</type>\n <destination_team_key>370.l.4801.t.7</destination_team_key>\n </transaction_data>\n </player>\n <player>\n <player_key>357.p.9317</player_key>\n <transaction_data>\n <type>drop</type>\n <source_team_key>370.l.4801.t.7</source_team_key>\n </transaction_data>\n </player>\n </players>\n </transaction>\n</fantasy_content>\n"

老实说，我不确定两个响应之间有什么区别，因为我已经得到了两个响应，我非常确定相同的XML输入和POST参数。
有人有任何见解吗？
答案 0 :(得分：0)
刚遇到同样的问题，这篇Stack Overflow文章是我在网上找到的唯一相关链接。决定是时候我回馈这个社区......
问题是Yahoo的交易页面上的一个示例XML是错误的。带有{}占位符且没有＆lt; faab_bid＆gt;的示例节点是正确的，但它下面的FAAB示例有＆lt; destination_team_key＆gt;而不是＆lt; source_team_key＆gt;作为“下降”交易的一部分。当我确保使用“source_team_key”而不是“destination_team_key”作为drop节点集时，事务开始工作。
我猜测错误代码25是一般错误，表明XML的某些部分是错误的或意外的。如果这不能解决您的问题，请尝试从第一个添加/删除示例XML开始，逐个填写值。
希望这有帮助。
