如何在XML的"Net::HTTP.post_form“中找到隐藏的空白或新行？
如何在XML的"Net::HTTP.post_form“中找到隐藏的空白或新行？
提问于 2015-04-16 12:59:20
我使用ruby Net::HTTP.post_form将XML发布到ConnectWise服务器，使用CompanyAPI。我得到了一个错误：
System.Xml.XmlException: Data at the root level is invalid. Line 1, position 1.从我能找到的所有东西来看，我可能在<?xml version="1.0" encoding="utf-8"?>前有一个空格或换行符。
以下是代码：
require 'net/http'
require 'uri'
require 'builder'
#f = File.new('cw.get_company.xml', 'w')
@cwhostname = 'cw_fqdn'
companyapi_url = 'https://' + @cwhostname + '/v4_6_release/apis/2.0/CompanyApi.asmx'
uri = URI(companyapi_url)
def cw_company_api_get_company
companyid = 'company_name'
integratorloginid = 'inegrator_login_id'
integratorpassword = 'inegrator_passwd'
companyidint = 0
xml = Builder::XmlMarkup.new(:indent=>2)
xml.instruct!
xml.tag!('soap:Envelope'){
xml.tag!('soap:Body'){
xml.tag!('GetCompany xmlns="https://'+@cwhostname+'"'){
xml.tag!('credentials'){
xml.CompanyId(companyid)
xml.IntegratorLoginId(integratorloginid)
xml.IntegratorPassword(integratorpassword)
}
}
xml.id(companyidint)
}
}
end
response = Net::HTTP.post_form(uri,[cw_company_api_get_company])
#puts cw_company_api_get_company
puts response.body以下是带有错误的完整输出：
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><soap:Code><soap:Value>soap:Receiver</soap:Value></soap:Code><soap:Reason><soap:Text xml:lang="en">System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Xml.XmlException: Data at the root level is invalid.

下面是在ConnectWise API文档中提供的一个示例XML：
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetCompany xmlns="http://connectwise.com">
<credentials>
<CompanyId>string</CompanyId>
<IntegratorLoginId>string</IntegratorLoginId>
<IntegratorPassword>string</IntegratorPassword>
</credentials>
<id>int</id>
</GetCompany>
</soap:Body>
</soap:Envelope>回答 1

它与空格无关。您的XML是完全不正确的。问题在于字符串：
xml.tag!('GetCompany xmlns="https://'+@cwhostname+'"')显然，它将整个字符串视为一个标记，生成结束标记为：
</GetCompany xmlns="https://connectwise.com">在代码中的任何地方，puts cw_company_api_get_company都可以很容易地看到这一点。属性将传递给构建器标记，如下所示：
xml.tag!('GetCompany', :xmlns => "https://#{@cwhostname}")另一个问题是您需要将id放在GetCompany标记中。总结：
def cw_company_api_get_company
companyid = 'company_name'
integratorloginid = 'inegrator_login_id'
integratorpassword = 'inegrator_passwd'
companyidint = 0
xml = Builder::XmlMarkup.new(:indent=>2)
xml.instruct!
xml.tag!('soap:Envelope'){
xml.tag!('soap:Body'){
xml.tag!('GetCompany', :xmlns => "https://#{@cwhostname}"){
xml.tag!('credentials'){
xml.CompanyId(companyid)
xml.IntegratorLoginId(integratorloginid)
xml.IntegratorPassword(integratorpassword)
}
xml.id(companyidint)
}
}
}
end希望这能有所帮助。
