node.js - Parse request with JSON.parse -

-

I try to parse a request with node.js , then next I I create: 

  app.get ('/ download', function (request, race) {var parseJSON = JSON.parse (request); on file = parseJson.fileName; res. Set the file; // set and send it.});   
 And I send a request with the Advanced Rest client:  
 URL:  http: // localhost: 5000 / download   
 method:  received   
 raw logic:  fileinfo: "C: //1//239698_n.jpg"   
 And this gives me the next error:  
  Syntax error: Unexpected token at o port at Object.parse (native) (c: \ node \ NodeJS \ express.js: 13: 24) On the callback (c: \ node \ NodeJS \ node_modules \ express \ lib \ router \ index.js: 164: 37) on the ultimate (c: \ node \ NodeJS \ node_modules \ express \ lib \ router \ index.js: 138: 11) near (c: \ n D \ NodeJS \ node_modules \ express \ lib \ router \ index.js: 145: 5) Router._dispatch (minus c: \ node \ NodeJS \ node_modules \ \ lib \ router \ index. Js: 173: 5 ) Object.router (less than c: \ node \ NodeJS \ node_modules \ express \ lib \ router \ index.js: 33: 10)   
 What can be reson?   
 
 
 You are not sending JSON. You are sending query string formatted logic. Whether you want to use or, shameless plug alerts, my modules, which format is atheist.

cmake set_source_files_properties not working properly -

-
I have a project in which. C is a group of files which need to be compiled as C files, but I need it to be compiled as C ++ code. I tried the solution I found, but did not work as expected. Instead of making filename.c only, it is compiled as C ++, it compiles all the files in my project as C ++ code. Without that call, all the files have been compiled as C. I also tried: set_source_files_properties ($ {FILES_SRC} property languages ​​C) set_source_files_properties (filename.c property languages ​​CFX) Where FILES_SRC variable keeps all my source files. I am CMK 2.8.12 and Visual Studio 11 ARM Generator. Any ideas how can I fix this? I finished compiling the library using C compiler and added a C ++ code to a different library For which I created a C interface so it can be told from my C library.

python - Writing Greek in matplotlib labels, titles -

I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
