optional(error domain=nsurlerrordomain code=-1012 "the operation couldn’t completed. (nsurlerrordomain error -1012.)" userinfo=0x7f9050e1f750 {nserrorfailingurlstringkey=https://rainforestcloud.com:9445/cgi-bin/post_manager, nsunderlyingerror=0x7f9050fe4eb0 "the operation couldn’t completed. (kcferrordomaincfnetwork error -1012.)", nserrorfailingurlkey=https://rainforestcloud.com:9445/cgi-bin/post_manager})

here snippet of code 

var therequest : nsmutableurlrequest =  nsmutableurlrequest(url: nsurl(string: base_url)!)     therequest.httpmethod = "post"     therequest.setvalue("text/html", forhttpheaderfield: "content-type")     therequest.addvalue("cloud-id", forhttpheaderfield: "001226")     therequest.addvalue("user", forhttpheaderfield: "john.lee@rainforestautomation.com")     therequest.addvalue("password", forhttpheaderfield: "rainforest")     var stringdata =  "confirm_message";     var requestbodydata = stringdata.datausingencoding(nsutf8stringencoding, allowlossyconversion: false)     therequest.httpbody = requestbodydata;     var response: nsurlresponse?     var error: nserror?     let urldata = nsurlconnection.sendsynchronousrequest(therequest, returningresponse: &response, error: &error)     if ((error) != nil)     {         println(error)      }     else     {         self.performseguewithidentifier("meterview", sender: self)     }     therequest.timeoutinterval = 0.20

postman api call images here response image

i have code connect rest api. uses jsonvalue, because assume value returned in json.

the way call 

datafromserver('file.php', ["parm1": "value1", "parm2": 2])  func datafromserver(file:string, var parms:dictionary<string, anyobject!>) -> jsonvalue {       let url = "\(serverurl)/\(file)"      let request = nsmutableurlrequest()     request.url = nsurl(string: url)     request.httpmethod = "post"      let boundary = "---------------------------29839217397249927731321937129879827"     let contenttype = "multipart/form-data; boundary=\(boundary)"      request.addvalue(contenttype, forhttpheaderfield: "content-type")      let body = nsmutabledata()      (key, value) in parms {          if value uiimage {             //if uiimage              if let img = value as? uiimage {                  var newwidth = 0                 var newheight = 0                 var sizelimit = 700 //in px                  let originalwidth = int(img.size.width)                 let originalheight = int(img.size.height)                  //get new size max w/h = 700                 if originalwidth > originalheight {                     //max width                     newwidth = sizelimit                     newheight = (originalheight*sizelimit)/originalwidth                 }else{                     newwidth = (originalwidth*sizelimit)/originalheight                     newheight = sizelimit                 }                  let newsize = cgsizemake(cgfloat(newwidth), cgfloat(newheight))                 uigraphicsbeginimagecontext(newsize)                 img.drawinrect(cgrectmake(0, 0, cgfloat(newwidth), cgfloat(newheight)))                 let newimg = uigraphicsgetimagefromcurrentimagecontext()                 uigraphicsendimagecontext()                 let imagedata = uiimagepngrepresentation(newimg)                  body.appenddata(("\r\n--\(boundary)\r\n" nsstring).datausingencoding(nsutf8stringencoding)!)                 body.appenddata(("content-disposition: form-data; name=\"\(key)\"; filename=\"tempimage.png\"\r\n" nsstring).datausingencoding(nsutf8stringencoding)!)                 body.appenddata(("content-type: application/octet-stream\r\n\r\n" nsstring).datausingencoding(nsutf8stringencoding)!)                 body.appenddata(nsdata(data: imagedata))             }           }else{              body.appenddata(("\r\n--\(boundary)\r\n" nsstring).datausingencoding(nsutf8stringencoding)!)             body.appenddata(("content-disposition: form-data; name=\"\(key)\";" nsstring).datausingencoding(nsutf8stringencoding)!)             body.appenddata(("\r\n\r\n" nsstring).datausingencoding(nsutf8stringencoding)!)             body.appenddata(("\(value)" nsstring).datausingencoding(nsutf8stringencoding)!)         }     }      body.appenddata(("\r\n--\(boundary)\r\n" nsstring).datausingencoding(nsutf8stringencoding)!)      request.httpbody = body      var urldata:nsdata?     var response: nsurlresponse?     var error: nserror?     urldata = nsurlconnection.sendsynchronousrequest(request, returningresponse: &response, error: &error)       if let serverdata = urldata {         if let data = response {             let astr = nsstring(data: serverdata, encoding: nsutf8stringencoding)             let json = jsonvalue(urldata)             println("return \(file): \(astr)")             return json         }     }      return jsonvalue("") }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
