使用ColdFusion将文件上传到Google云端硬盘

Question

*更新为更好的第二部分 - 现在得到"308恢复不完整",即使文件应该只是一个上传!

我使用cfgoogleRay Camden 的基础.但Google已弃用文档上传代码.新标准是Resumable Media Uploads.

我在上面引用的Google文档中使用了这部分(包括"启动可恢复的上传请求").

呼叫页面:

<cfset application.cfc.Google                   = createObject('component','#path_cf_cfc#Google') />
<cfset application.cfc.GoogleDocs               = createObject('component','#path_cf_cfc#GoogleDocs') />

<cfset gtoken = application.cfc.GoogleDocs.authenticate(emailaddress,password)>

<CFSET testdoc = "a\filepath\documentname.doc">
<CFSET FileType = "application/msword">
<CFSET FileTitle = "test_001">

<cfset temp = application.cfc.GoogleDocs.upload_auth("#Application.Map.DocStorage##tv.testdoc#",FileType,FileTitle)>  

<CFSET uploadpath = Listgetat(Listgetat(temp.header,ListContains(temp.header,"https://docs.google.com","#chr(10)#"),"#chr(10)#"),2," ") >  

<cfset temp2 = application.cfc.GoogleDocs.upload_file("#Application.Map.DocStorage##tv.testdoc#",FileType,FileTitle,uploadpath)>

该代码适用于并包括cfset临时行(获取唯一上载URI)

以下是upload_auth的代码:

<cffunction name="upload_auth" access="public" returnType="any" hint="I get a uniqu URI from Google API." output="false">
<cfargument name="myFile" type="string" required="true" hint="filepath to upload.">
<cfargument name="myType" type="string" required="true" hint="application/msword"> 
<cfargument name="myTitle" type="string" required="true" hint="name of doc"> 

<cfset GoogleUrl = "https://docs.google.com/feeds/upload/create-session/default/private/full">
<cfset GoogleVersion = 3> 
<cfset FileSize = createObject("java","java.io.File").init(myFile).length()>

<cfhttp url="#GoogleUrl#" method="post" result="diditwork" resolveurl="no">
<cfhttpparam type="header" name="Authorization" value="GoogleLogin auth=#getAuth(variables.docservice)#">
<cfhttpparam type="header" name="GData-Version" value="#GoogleVersion#">
<cfhttpparam type="header" name="Content-Length" value="0">
<cfhttpparam type="header" name="X-Upload-Content-Type" value="#myType#">
<cfhttpparam type="header" name="X-Upload-Content-Length" value="#FileSize#">
<cfhttpparam type="header" name="Slug" value="#myTitle#">

</cfhttp>

<cfreturn diditwork>
</cffunction>

好的 - 这么好.但这是它崩溃的地方:

运行upload_file会从Google返回"308 Resume Incomplete"(以免它不是400!).Arrgh!

这是upload_file -

<cffunction name="upload_file" access="public" returnType="any" hint="I upload the document." output="false">
<cfargument name="myFile" type="string" required="true" hint="filepath to upload.">
<cfargument name="myType" type="string" required="true" hint="like application/msword"> 
<cfargument name="myTitle" type="string" required="true" hint="name of doc"> 
<cfargument name="myAuthPath" type="string" required="true" hint="call auth"> 

<cfset FileSize = GetFileInfo(myFile).size >
<CFSET tv.tostartwithzero = FileSize - 1>

<CFFILE action="read" file="#myfile#" variable="FileText">

<cfhttp url="#myAuthPath#" method="put" result="diditwork" resolveurl="no" multipart="yes" charset="utf-8" >
<cfhttpparam type="header" name="Authorization" value="GoogleLogin auth=#getAuth(variables.docservice)#">
<cfhttpparam type="header" name="GData-Version" value="#variables.GoogleVersion#">
<cfhttpparam type="header" name="Content-Length" value="#FileSize#">
<cfhttpparam type="header" name="Content-Range" value="bytes 0-#tv.tostartwithzero#/#FileSize#">
<cfhttpparam type="header" name="Content-Type" value="#myType#">

<cfhttpparam type="body" value="#trim(FileText)#">

</cfhttp>

<cfreturn diditwork>
</cffunction>

所以,我们有它 - 我陷入困境.我可以得到唯一的URI,但(也许是因为它是深夜)我脑子里死了我做错了,否则完成文件上传.

所有帮助表示赞赏.

我强烈建议在这里采取不同的方法。您所走的道路有两个大问题：

• 代码似乎正在使用已弃用的客户端登录身份验证机制，并且使用用户名/密码而不是 OAuth。
• 使用已弃用的文档列表 API，而不是较新的 Drive API。

由于您可以调用 java，因此我建议使用纯 Java 编写上传代码，然后根据需要从 CF 页面调用它。
