Node.js Express REST API - accessing JSON url params with GET request -

-

I have a final end point, which is / geo / search and long to be sent as part of it Requires Latitude / Coordinate Request (Geo Polygon).

  • Is there a way that I can use JSON in the GET request? I was thinking that URL encoding can be a solution: data on encodeurIComponent ({"coordinate": [[122.610168,37.598167], [- 122.288818,37.598167], [- 122.2,88,818, 37.845833], [- 122.610168,37.845833], [- 122.610168,37.598167]]});

  • How do I access these parameters in the path?

    • Reply to # 1 - Thanks @ MCCF

    Using JQuery.param:

    Customer: 

      test = {"coordinate": [[- 122.610168,37.598167], [- 122.288818, 37.598167], [-122.288818,37.845833], [- 122.610168,37.845833], [- 122.610168,37.598167]]}; Console.log ($. Ultimate (test));

    Output: 

      Coordinates% 5B0% 5D% 5b% 5D = -122.6,10,168 & amp; Coordinate% 5B0% 5D% 5b% 5D = 37.5, 98167 & amp; Coordinate% 5B1% 5D% 5b% 5D = -122.2,88818 & amp; Coordinate% 5B1% 5D% 5b% 5D = 37.5, 98167 & amp; Coordinate% 5B2% 5D% 5b% 5D = -122.2,88818 & amp; Coordinate% 5B2% 5D% 5b% 5D = 37.845833 & amp; Coordinate% 5B3% 5D% 5b% 5D = -122.6,10,168 & amp; Coordinate% 5B3% 5D% 5b% 5D = 37.845833 & amp; Coordinate% 5B4% 5D% 5b% 5D = -122.6,10,168 & amp; Thanks for Broad:  
     Server - Express way:  
        
     Router .Get ('/ search_polygon', function (request, race) {console.log ('server received:' + JSON.stringify (req.query.coordinates)); ...  
     < P> Output: 
     
      Server received: [["-122.6,10,168", "37.5, 98167"], ["- 122.2,88, 818 "," 37.5, 98167 "], [" - 122.2, 88,818 "," 37.8,45,833 "], [" -122.6,10,168 "," 37.8,45,833 "], [" - 122.6,10,168 "," 37.5, 98167 "]]  
     
     My issue is part of the path In the cross as The was trying to, and not as in as parameters that they should be.

Edit: In the socket: The CanReceive () argument was the reason I was checking the input 1 millisecond While stepping into GDB, everything worked out. I have a problem with C sock send () / recv () do nothing if they are in non-debug mode. Even if std :: cout can not return their return value for some reason std :: cout is not working in my method I std: : Cerr can not even make a mistake It does not make sense to check that in GDB, because everything works perfectly as a virus in non-debug mode.

I'm trying to display a static page with Go. Go: Package main import "net / http" function main () {fs: = http.FileServer (http.Dir ("static / house")) Http: .handle ("/", fs) http.ListenAndServe (": 4747", zero)} directory: project / stable home Html edit.html project.go When I run it, the web page displays links to edit.html and home.html instead of displaying a static page from home.html is. What am I doing wrong. Is this the best way to serve files? I know that there are other ways like From the HTML / templates package, but I'm not sure what is the difference between each of these methods and when. Thanks! fancy main () {http.Handle ("/", http.FileServer (Http) .ir ("static")) http.ListenAndServe (": 4747", zero)} You do not need static / home , just Static . and when you do not have index.html in / static , the directory instead Content appears.
