如何发送来自cfclient.camera.getPictureFromAlbum的图像

Question

我想将图像上传到来自图像库的服务器。第一部分通过使用：

<cffunction access="public" name="getPicAlbum" returntype="void" > 
    <cfset opt = cfclient.camera.getOptions()> 
    <cfset res = cfclient.camera.getPictureFromAlbum(opt,true)> 
    <cfset displayMessage("picAlbum <br><hr>", false)> 
    <cfset document.getElementById('imgBase64').value=#res#> 
    <cfset uploadImgAsJpg()> 
</cffunction> 

一旦我读取图像，我把base64值放入一个隐藏的文本字段。然后，我调用uploadImgAsJpg（）函数。

function uploadImgAsJpg() { 
    var base64Img = document.getElementById('imgBase64').value; 
    try { 
     myImage = cfclient.file.readAsBase64(base64Img); 
     cfclient.file.write("newImg.jpg", myImage); 
     // where does this newImg.jpg go? 
     var oldFileSystem = cfclient.file.getFileSystem(); 
     //Get file object from the path 
     var fileObj = cfclient.file.get("newImg.jpg"); 

     displayMessage("uploadImgAsJpg image - " + fileObj.fullPath + "<br><hr>", false); 

     var newFilePath = copyFileFromTempToPersistentFileSystem(fileObj.fullPath); 

         //Now upload file to the server 
         uploadFileToServer(newFilePath); 

         //Delete temporary file 
         cfclient.file.remove(fileObj.fullPath); 
         displayMessage("Deleted temporaty file " + fileObj.fullPath + "<br><hr>"); 
        } catch (any e) { 
         displayMessage("ERROR " + e.message + "<br><hr>"); 
         displayMessage("ERROR " + e.detail + "<br><hr>"); 
         displayMessage("ERROR " + e.TagContext + "<br><hr>"); 
        } 

       } 

一些这个代码是从http://ramkulkarni.com/blog/cfmobile-example-taking-picture-and-uploading-to-coldfusion-server/

复制当我运行上面的代码，我cfcatch显示：指定的错误文件/目录没有被发现。

cfclient.file.write保存文件在哪里？有没有更好的方法来做到这一点？

这解决了我的问题。这从库中获取图片并将其发送到服务器。

希望它可以帮助别人。

    <cfset opt = cfclient.camera.getOptions()> 
    <cfset res = cfclient.camera.getPictureFromAlbum(opt,false)> 
    <cfset imgStr = cfclient.file.readAsBase64(res)> 
    <cfset imgFile = cfclient.file.write("newImg.jpg",imgStr)> 
    <cfset cfclient.file.upload("newImg.jpg","xxx.com/?vw=uploadBase64",uploadSuccess,onUploadError)> 
</cffunction>
