HttpQuery function not working and showing empty msgbox, while it should show html codes of page?

14 Jul 2019, 02:34

Hello friends..

I want to get full html codes from https://cmyip.com/ as shown in this video-
https://www.youtube.com/watch?v=wTYhMgZNB8M&t=243s

for this i tried to use these codes-

Code: Select all

httpQuery(url, "https://cmyip.com/")
VarSetCapacity(url,-1)
MsgBox % url


; Below, there is httpQuery Function's codes

But, when i run these codes after opening the site- https://cmyip.com/ in Chrome browser, it shows an empty msgbox.

Please tell me what i am doing wrong..

Thanks a lot..

@Sabestian Caine
The library you use is very-very outdated, just don't use it.
You could using something like this instead:

Code: Select all

url := "https://cmyip.com/"
whr := ComObjCreate("WinHttp.WinHttpRequest.5.1")
whr.Open("GET", url, false)
whr.Send()
MsgBox, % html := whr.ResponseText
RegExMatch(html, "(\d+\.){3}\d+", ip)
MsgBox, % ip

Thanks dear teadrinker... your really solved my problem... above codes are working great...

Sir, I want to ask one more thing..

As i want to make a POST request in https://cmyip.com/ then what should i do?
As I want to search this ip address - 169.45.78.148 in https://cmyip.com/ site then what should i do?

please look at this image-
14_07_19 @8_31_23.PNG
14_07_19 @8_31_23.PNG (149.26 KiB) Viewed 992 times
You can see there is an search box and i want this ip address - 169.45.78.148 to set in the above search box and search it using above codes, then what should i do?

Please help and guide..

Thanks a lot...

The type of the request is here: whr.Open("GET", url, false), so if you want to sent POST request, specify: whr.Open("POST", url, false), but in this case you don't need it.

Enter ip in the field, press the search button, than you will see the url you need in the address bar.

Code: Select all

url := "https://cmyip.com/search-ip.php?ip=169.45.78.148"
whr := ComObjCreate("WinHttp.WinHttpRequest.5.1")
whr.Open("GET", url, false)
whr.Send()
html := whr.ResponseText
; MsgBox, % html

RegExMatch(html, "Host Name:\s+(\S+).*?"
               . "City:\s+(\S.*?)\s*<.*?"
               . "Region:\s+(\S.*?)\s*<.*?"
               . "Country:\s+(\S.*?)\s*<.*?"
               . "ISP:\s+(\S.*?)\s*<", match)
               
MsgBox, % "Host Name: " . match1 . "`n"

Sir, could you please give me a good example of POST request, i.e. where should i use whr.Open("POST", url, false) ? I want to know is post request used to set data or strings into edit fields of websites? Please guide.. Thanks ..

The POST request is used in cases, when you need to send to the server some data, such as a file, JSON string or password/login. Unfortunately, there is no simple example to demonstrate this.
The following code sends an image file to imgur.com and receives a JSON string that contains the identifier of the image you uploaded.

Code: Select all

; sending an image file to imgur.com

FileSelectFile, filePath,, %A_ScriptDir%, Choose an image file, Images (*.gif; *.ti*f; *.jp*g; *.png; *.bmp)
if !filePath
   Return
url := "https://imgur.com/upload"
FileGetSize, size, % filePath

CreateFormData(postData, hdr_ContentType, {file: [filePath]})
whr := ComObjCreate("WinHttp.WinHttpRequest.5.1")
whr.Open("POST", url, false)
whr.SetRequestHeader("Content-Type", hdr_ContentType)
whr.SetRequestHeader("Content-Length", size)
whr.SetRequestHeader("Referer", url)
whr.SetRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0")
whr.Send(postData)

if ( (status := whr.Status) != 200 )

}

The POST request is used in cases, when you need to send to the server some data, such as a file, JSON string or password/login. Unfortunately, there is no simple example to demonstrate this.
The following code sends an image file to imgur.com and receives a JSON string that contains the identifier of the image you uploaded.

Code: Select all

; sending an image file to imgur.com

FileSelectFile, filePath,, %A_ScriptDir%, Choose an image file, Images (*.gif; *.ti*f; *.jp*g; *.png; *.bmp)
if !filePath
   Return
url := "https://imgur.com/upload"
FileGetSize, size, % filePath

CreateFormData(postData, hdr_ContentType, {file: [filePath]})
whr := ComObjCreate("WinHttp.WinHttpRequest.5.1")
whr.Open("POST", url, false)
whr.SetRequestHeader("Content-Type", hdr_ContentType)
whr.SetRequestHeader("Content-Length", size)
whr.SetRequestHeader("Referer", url)
whr.SetRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0")
whr.Send(postData)

if ( (status := whr.Status) != 200 )
   MsgBox, % "Error, whr.status:" . status
else {
   MsgBox, % JSON := whr.responseText
   RegExMatch(JSON, """hash"":""\K[^""]+", hash)
   MsgBox, % Clipboard := "https://imgur.com/" . hash
}

CreateFormData(ByRef retData, ByRef retHeader, objParam) {
   new CreateFormData(retData, retHeader, objParam)

Thanks a lot dear teadrinker for these great codes... You are really awesome...

Sir, i am trying to learn more about web api, I come across these codes from this site - https://the-automator.com/example-webservice-api-call-connecting-to-zoom-extracting-info/

Code: Select all

IniRead, API_Token ,Auth.ini,API, Token
IniRead, API_Key   ,Auth.ini,API, Key
IniRead, API_Secret,Auth.ini,API, Secret
 
;~  EndPoint:="https://api.zoom.us/v1/user/list" ;get list of users under your account
;~  EndPoint:="https://api.zoom.us/v1/meeting/list" ;get list of meetings for a given user
EndPoint:="https://api.zoom.us/v1/meeting/get" ;get specific meeting info
;~  QueryString:=QueryString_Builder({"api_key":API_Key,"api_secret":API_Secret,"data_type":"XML","host_id":"pPzEua3eSDerCD2WO3JbUg"})
QueryString:=QueryString_Builder({"api_key":API_Key,"api_secret":API_Secret,"data_type":"XML","id":"693773857","host_id":"pPzEua3eSDerCD2WO3JbUg"})
 
;********API call**********************
HTTP := ComObjCreate("WinHttp.WinHttpRequest.5.1") ;Create COM Object
HTTP.Open("POST", EndPoint . QueryString) ;GET & POST are most frequent, Make sure you UPPERCASE
HTTP.Send() ;If POST request put data in "Payload" variable
Response_data:= HTTP.ResponseText ;Save the text that is returned
SciTE_Output(Response_data) ;Text,Clear=1,LineBreak=1,Exit=0
 
;***********query string builder******************* 
QueryString_Builder(kvp){
for key, value in kvp
  queryString.=((A_Index="1")?(url "?"):("&")) key "=" value
return queryString
}



I watched this video too - https://www.youtube.com/watch?v=tw3kLhoRhnI

But, i am getting very little..

Please tell me, as he is posting these values - QueryString_Builder({"api_key":API_Key,"api_secret":API_Secret,"data_type":"XML","id":"693773857","host_id":"pPzEua3eSDerCD2WO3JbUg"}) in QueryString
What are these values.?
Secondly- what is endpoint? Does endpoint mean the name of website?
and thirdly why he needs to use QueryString_Builder(kvp) function?

Please help and guide..

Thanks teadrinker...

Thanks a lot dear teadrinker... You really helped me a lot... thanks for your kind support..

Sir, please tell me one last thing- what is requestheaders which you used in your codes like-

Code: Select all

whr.SetRequestHeader("Content-Type", hdr_ContentType)
whr.SetRequestHeader("Content-Length", size)
whr.SetRequestHeader("Referer", url)
whr.SetRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0")
Why we use SetRequestHeaders? please tell.. Thanks...

This is some info that the server needs to determine what kind of data we sent, what to do with it and what the response we expect to receive.
