خطأ عنوان URL غير صالح عند نشر الملفات برمجيا إلى مكتبة النمط باستخدام وحدة نمطية

Question

نستخدم ميزة لنشر الملفات الشائعة في WebParts لدينا إلى مكتبة النمط في SharePoint Server 2010، واجهنا مؤخرا المشكلة حيث لم يتم تحديث الملفات عندما نشرنا نسخة محدثة من الميزة. (ملاحظة: يمكنني استخدام مصطلح "الإصدار" فضفاضة هنا - لا نقوم بإصدار WebParts لدينا). بعد البحث حولها، وجدت أن هذه المشكلة (أي الوحدات النمطية ستنشر الإصدار الأولي من ملف ولكنها لن تقوم بتحديثها) تم توثيقها على عدد من المدونات. انتهى إبرام كل ذلك بتحديث الملفات، تحتاج إلى القيام بذلك برمجيا باستخدام مفصول. لقد وجدت اثنين من الحلول المختلفة:

جربت كل من الحلول، لكنه انتهى بالاستمرار في حل Johan مع بعض القرص الصغير لسيناريونا.

واجهت nullrefenceException عندما ران رمز Johan، ولكن هذا كان لأننا ليس لدينا سمة مسار على عنصر الوحدة النمطية. لقد استبدلت المكالمة لاسترداد سمة المسار مع مكالمة لاسترداد سمة URL. ثم واجهت الخطأ التالي: giveacodicetagpre.

لقد وجدت مختلف مدونات مختلفة تحدد الحلول لهذا الخطأ ولكن لا شيء قد حلها بالنسبة لي:

هل لدى أي شخص أي اقتراحات أخرى جانبا من السجلات؟

Answer 1

After doing a lot of reading and after debugging the feature receiver, I discovered two things:

1. One of our files (which was introduced after the original version was deployed but before the current version) didn't exist in the Style Library on the SharePoint site. i.e. it had never been deployed. I checked a couple of our test servers and the file wasn't there either so this confirmed it wasn't isolated to my dev machine. This "missing" file was the file throwing the Invalid URL error when SPWeb.Files.Add was called. I confirmed that the file did exist in the hive and that the Add method could create new files. I had a look at what SPWeb.GetFile() was returning. Interestingly enough, the SPFile object returned when retrieving the "virtual file" had Exists = true... but... the file doesn't exist on the server??? (Interesting post here on SPWeb.GetFile(): http://blog.mastykarz.nl/inconvenient-spwebgetfilestring/). I switched to using GetFileOrFolder() and casting to SPFile but my problem still wasn't resolved.

2. After looking again at Johan's code, I decided to see if there was something else in the call to Add that could be causing an issue. I re-examined our elements.xml file to see if the entry for the "missing" file was different from the other file entries. This ended up being where my problem was... the entry for the "missing" file didn't have all of the attributes that other entries had. In particular, it was missing the Type and IgnoreIfExists attributes.

   <File Path="Style Library\Assets\Scripts\JQuery\JQueryDollarFix.js" Url="Assets/Scripts/JQuery/JQueryDollarFix.js" />
   

   I updated the entry to be:

   <File Path="Style Library\Assets\Scripts\JQuery\JQueryDollarFix.js" Url="Assets/Scripts/JQuery/JQueryDollarFix.js" Type="GhostableInLibrary" IgnoreIfAlreadyExists="True"/>
   

   I re-deployed the wsp to the SharePoint site and activated the feature. The FeatureReceiver code ran successfully and the files were updated and checked into the Style Library.
