毕加索:无法识别的HTTP方案请求类型

问题描述

我正在同步加载图像，以便在加载图像后显示通知.

I am loading images synchronously to display notification once the image is loaded.

bitmap = picasso.load(imageUrl).get();

工作正常，但今天我有一个例外:

It was working fine but today I got an exception:

Fatal Exception: java.lang.IllegalStateException: Unrecognized type of request: Request{

       at com.squareup.picasso.BitmapHunter$2.load(BitmapHunter.java:66)
       at com.squareup.picasso.BitmapHunter.hunt(BitmapHunter.java:206)
       at com.squareup.picasso.RequestCreator.get(RequestCreator.java:396)
       at com.jumbotail.app.utils.JtImageLoader.loadImageSync(JtImageLoader.java:397)
       at com.jumbotail.app.notifs.JumboGcmIntentService.readInboundIntent(JumboGcmIntentService.java:213)
       at com.jumbotail.app.notifs.JumboGcmIntentService.buildNotification(JumboGcmIntentService.java:273)
       at com.jumbotail.app.notifs.JumboGcmIntentService.onHandleIntent(JumboGcmIntentService.java:49)
       at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:65)
       at android.os.Handler.dispatchMessage(Handler.java:99)
       at android.os.Looper.loop(Looper.java:174)
       at android.os.HandlerThread.run(HandlerThread.java:60)

我知道当没有请求处理程序可以处理请求时，毕加索会抛出此错误.

I understand that this error is thrown by Picasso when no request handlers can handle the request.

现在，根据请求的Uri方案(为http) canHandleRequest(Request data) 的 NetworkRequestHandler 应该返回了true.

Now, as per the Uri scheme of the request (which is http) canHandleRequest(Request data) method of NetworkRequestHandler should have returned true.

但是所有请求处理程序都返回了false，包括NetworkRequestHandler.因此， ERRORING_HANDLER 由毕加索返回，导致出现异常:IllegalStateException("Unrecognized type of request: " + request).

But all the request handlers returned false including NetworkRequestHandler. Thus, ERRORING_HANDLER was returned by Picasso resulting into the exception : IllegalStateException("Unrecognized type of request: " + request).

对此异常还有其他解释吗?

Is there any other explanation to this exception?

我还在毕加索提出了一个问题.

推荐答案

特别是我遇到了此错误，因为如错误所提到的，我获取的URL不是处理程序可以使用的有效URL.特别是，URL字符串在"http"之前有空格，例如:

In particular I had this error because the URL I was getting, as the error mentions, is not a valid URL that a handler can use. In particular, the URL string had spaces before the "http", like:

" http://example.com/image.jpg".

所以我只需要在url字符串上调用trim()，然后再将其加载到Picasso中，就可以了！

So I just had to call trim() on the url string, before loading it with Picasso, and worked great!
