javascript - require filename while downloading file using request module nodejs -

-

I use the request module in nodes to download the file (image file only) using this I'm doing, 

  request ('http://google.com/doodle.png'). Pipe (fs.createWriteStream ('doodle.png')),   
 or  
  request (url) .pipe (fs.createWriteStream (filename)) ,   
 But I only have url available and I need it to protect the file from its real name, so I must get the file name from the given url,  
  Please suggest to me how the last part of the URL has been removed   
 Thank you in advance ...   
 
 
 A simple solution can be:  
  var path = required ('path'); Var FS = Requirement ('FS'); // ... var filename = path.basename (url); Request (url) .pipe (fs.createWriteStream (file name));

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

C++ Array Type Not Assignable in Copy Constructor -

-
I have a simple class that represents the triangle, which consists of three arrays square triangle {public: double x [3]; Double y [3]; Unsigned four colors [3]; }; I want to create objects in this square on the heap, then pass on those functions which will use the value from the array. Since I am in these items, I need to make a deep copy to make a copy. Triangle (const triangle and obj) {X = new double [3]; Y = new double [3]; Color = new unsigned char [3]; For (int i = 0; i I keep the following error: "Error: array type 'double [3]' is not assignable for each of the three arrays. I am taking the same view as discussion, and I do not know why I am unable to create a new array. The answer is also the same approach. Does anyone have any insights? Looks like I'm really stupid. I'm taking the same approach as discussed in this video. In the video, you can see that he started the array Read on the member-preliminary list and how it is dif...
