当上传间歇性SSL错误使用Facebook的Andr​​oid的SDK 3.0张照片 [英] Intermittent SSL error when uploading photos using Facebook Android SDK 3.0

问题描述

我使用的Facebook的Andr​​oid SDK 3.0照片上传到我的专辑。一切正常，但有时第一次上传失败，一个有些出人意料的SSL错误。

I'm using Facebook Android SDK 3.0 to upload a photo to my album. Everything works, but sometimes the first upload fails with a somewhat unexpected SSL error.

请参阅功能 toHttpConnection 的<一个href="https://github.com/facebook/facebook-android-sdk/blob/master/facebook/src/com/facebook/Request.java"相对=nofollow> Request.java 。

try {
        connection = createConnection(url);

        serializeToUrlConnection(requests, connection);
    } catch (IOException e) {
        // THIS IS WHERE THE ERROR ORIGINATES FROM!
        throw new FacebookException("could not construct request body", e);
    } catch (JSONException e) {
        throw new FacebookException("could not construct request body", e);
    }

悬停电子在Eclipse中显示以下信息：

Hovering e in Eclipse shows this information:

这是在SDK中的错误？别的任何人遇到这样？而更重要的是，如何解决呢？

Is this a bug in the SDK? Did anybody else encounter this? And more importantly, how do I fix it?

推荐答案

我的几乎的准备解决我的previous（删除）的答案，直到我遇到了这篇文章：<一个href="http://vikaskanani.word$p$pss.com/2011/01/11/android-upload-image-or-file-using-http-post-multi-part/" rel="nofollow">http://vikaskanani.word$p$pss.com/2011/01/11/android-upload-image-or-file-using-http-post-multi-part/

I was almost ready to settle for my previous (removed) answer, until I came across this article: http://vikaskanani.wordpress.com/2011/01/11/android-upload-image-or-file-using-http-post-multi-part/

我决定给它一个镜头，它似乎工作！这是我的code：

I decided to give it a shot, and it seems to work! Here's my code:

for (Bitmap b : bitmaps) {
    // id is just a string
    String response = executeUpload(b, id);

    // do something with the response
}

private String executeUpload(Bitmap b, String id) throws MalformedURLException, IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    b.compress(CompressFormat.PNG, 100, baos);
    byte[] data = baos.toByteArray();

    HttpPost postRequest = new HttpPost("https://graph.facebook.com/me/photos");
    HttpParams params = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(params, 3000);
    HttpClient httpClient = new DefaultHttpClient();
    httpClient.setHttpRequestRetryHandler(new DefaultHttpRequestRetryHandler(2, true));

    ByteArrayBody bab = new ByteArrayBody(data, id + ".png");
    MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
    reqEntity.addPart("access_token", new StringBody(activeFacebookAccessToken));
    reqEntity.addPart("message", new StringBody(""));
    reqEntity.addPart("picture", bab);
    postRequest.setEntity(reqEntity);
    HttpResponse response = httpClient.execute(postRequest);
    BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
    String s;
    StringBuilder builder = new StringBuilder();
    while ((s = reader.readLine()) != null) {
        builder = builder.append(s);
    }

    return builder.toString();
}

正如上面的链接讨论，您必须安装最新的的HttpClient （在的 http://hc.apache.org/downloads.cgi ）。

要注意的另一个重要的事情是，Facebook的支持720像素的两种维度的最大图像尺寸。在我的code，我缩放位图是在该尺寸的限制做的上传极大地提高性能了。

Another important thing to note is that Facebook supports a maximum image size of 720 px in either dimension. In my code I'm scaling the bitmap to be within that size limit before doing the upload which greatly improves performance.
