我有一个Facebook应用程序的画布，写在AS3和使用Adobe Facebook的API。

I have a Facebook canvas app, written in AS3, and using the Adobe Facebook API.

我可以连接，获取好友列表，选择一个朋友，所有的东西是工作的罚款。问题是，当我尝试发布到朋友的墙上。我想张贴图片。就是这样，只是一个形象。

I can connect, get a list of friends, pick a friend, all that stuff is working fine. The problem is when I try and post to a friend's wall. I am trying to post an image. That's it, just an image.

图片为200×200，可满足不比50×50和外部的3小的Facebook的guidlines：1的比例

The image is 200x200, which meets the facebook guidlines of not being smaller than 50x50 and outside of a 3:1 ratio.

我已经找遍了所有在interwebz的答案，并已经尝试了所有的例子我能找到。我已经拼凑看起来像是有前途的尝试，只为有图像仍然没有露面。其他信息，如邮件，链接等，确实显示了，如果我有它。只是没有图片。这里是code，看起来最有前途的依据是什么Facebook的文档说。

I have searched all over the interwebz for an answer and have tried all examples I can find. I have cobbled together what looked like promising attempts, only to have the image still not show up. Other info, like the message, link etc, do show up if I include it. Just no picture. Here is the code that looked the most promising based on what facebook docs say.

Facebook.api('/' + friendID  +'/feed', onPicPosted, {image:imageToPost, message:messageToPost, fileName:'FILE_NAME'}, URLRequestMethod.POST);

friendID 是所选择的朋友， imageToPost 是一个位图， onPicPosted 是回调，它返回成功，即使图像不显示出来。

friendID is the selected friend, imageToPost is a bitmap, onPicPosted is the callback, which returns successful, even though the image does not show up.

我自己也尝试根据别人的建议，一个微小的变化，改变的图片为图片在params对象。

I have also tried a slight variation based on someone's suggestion, changing image to picture in the params object.

Facebook.api('/' + friendID  +'/feed', onPicPosted, {picture:imageToPost, message:messageToPost, fileName:'FILE_NAME'}, URLRequestMethod.POST);

权限已被正确地请求和授予（publish_stream，也user_photos'和'friends_photos只是为了安全的措施）。

permissions have been properly requested and granted ('publish_stream', and also 'user_photos' and 'friends_photos' just for safe measure).

这个问题推迟交货，因此是急我摸不着头脑。如果任何人有关于如何完成发布的图像（位图，在Flash创建的）到所选择的朋友墙的想法，请大家帮忙！谢谢！

This issue is delaying a delivery so it is urgent I figure this out. If anyone has an idea of how to accomplish posting an image (bitmap, created in flash) to a selected friend's wall, please help! Thanks!

推荐答案

在一些调查研究：

这是不可能的。 图片是不是一个属性预期，而图片是，和图片需要一个URL作为它的值不是一个位图。

This is not possible. image is not a property expected, rather picture is, and picture expects a url as its value not a bitmap.

解决的办法是首先将图像上传到通过PHP的服务器，然后张贴图像与返回的URL。

The solution was to first upload the image to a server via php, then post the image with the returned url.

此外，作为一个侧面说明，通过一个应用程序发布到朋友的墙上的图像不能超过90x90大。如果发布到用户自己的壁，而不是在用户的好友的壁也可以是产生大于

Also, as a side note, an image posted to a friend's wall via an app can be no larger than 90x90. It can be larger than that if posted to the user's own wall, but not to the user's friends' walls.
