kandi X-RAY | rDSN Summary
robust distributed system nucleus (rdsn) is a framework for quickly building robust distributed systems. it has a microkernel for pluggable components, including applications, distributed frameworks, devops tools, and local runtime/resource providers, enabling their independent development and seamless integration. the project was originally developed for microsoft bing, and now has been adopted in production both inside and outside microsoft. the core of rdsn is a service kernel with which we can develop (via service api and tool api) and plugin lots of different application, framework, tool, and local runtime modules, so that they can seamlessly benefit each other. here is an incomplete list of the pluggable modules. rdsn provides flexible configuration so that developers can combine and configure the modules differently to enable different scenarios. all modules are loaded by dsn.svchost, a common process runner in rdsn, with the given configuration file. the following table lists some examples (note dsn.core is always required therefore omitted in modules column). | scenarios | modules | config | demo | |----------|---------------|--------|------|

QUESTION
I tried to sole this problem myself for a few days searching on examples and documentations, also it wasn't solved on ruSO. So, I hope that solution will be found here, on enSO.
I develop a service for automatic creation of ads at Vk social network using Python and Google App Engine. Initially, pictures for ads are loaded to my server (part 1), then they are uploaded to Vk server at some time (parts 2.1 and 2.2). It seems that pictures are loaded and stored on my server correctly (I downloaded them and compared with original ones — every byte is the same). But I attach the part 1 code just in case.
To upload a picture to Vk.Ads firstly I need to get a URL — this is simple, so skip it. Secondly, I need to send a POST request to this link with field file
with binary content of the photo (API documentation). I created two ways for that (2.1 and 2.2), but both of them returns errcode: 2
which means corrupted file
. To my mind, the problem is about the requests, but I don't exclude the possibility of it files uploading/storage on my server, or some strange work of the API. I'll appreciate any answers and comments.
