I would like to know how to send correctly cookies value of timezone in HTTP request.
Code from response using HTTLiveHeaders in firefox:
Cookie: YSC=FcoGhPJts60; CONSENT=YES+cb.20220329-15-p1.en+FX+439; PREF=tz=Europe.London; GPS=1; VISITOR_INFO1_LIVE=v-FuzDqhJuF
My code:
Dim timeZone As String = "tz=Europe.London"
req.Cookies.Container.Add(New Uri("https://www.website.com"), New Cookie("PREF", timeZone))
because normally after PREF there is also "=" sign, but in HTTP request we don't need to add it, but it have another "=" so I'm not sure if it includes or not.
thanks for help.

I tried to search for a quick answer to this but I did not see a response...so I apologize if this is redundant.
I am pretty new to VBA and only use it to pull data from APIs to make my life easier.
My question is about the response im getting from a particular API. HEre is the code im using:
Dim URL As String: URL = "API URL HERE in json format"
Dim Http As New WinHttpRequest
Dim Resp As String
Http.Open "GET", URL, False
Http.Send
Resp = Http.ResponseText
Debug.Print Resp
So the Resp text is complete gibberish...is this a security thing? I pass a security key successfully when I use it in the browser so I assumed it was not that.... I have used this exact method on numerous APIs but this is the first time I have seen this garbled response. FYI the url I am using works just fine in a browser.
The Resp looks like this for example:
gõi:?ñq¢²^2?7AÄ??æºz³Gs=Î Ü?¬«¤%?$ÖÉ'q¯¼|?¼²ôue¦½Þ"HË!ø5[4]s½?·Þ.OÛÃBh×?4"rÊÊ[r7
Thanks for any help!

I'm trying to send a POST request and format the query string in a specific format. Order doesn't matter aside from the first parameter, but I haven't been successful.
What I need:
localhost/someapp/api/dosomething/5335?save=false&userid=66462
What some of my attempts have spit out:
http://localhost/someapp/api/dosomething/?Id=29455&save=false&userId=797979
http://localhost/someapp/api/dosomething/?save=false&userId=797979
How I formatted the request:
request.AddQueryParameter("Id", "29455");
request.AddQueryParameter("save", "false");
request.AddQueryParameter("user", "4563533245");
If I try AddParameterfor Id it doesn't get appended on the query string (I'm thinking because it's a POST and not a GET), so that won't work. The API isn't expecting a form, it's expecting :
(string id, List<Dictionary<string,string>>)
I could use a StringBuilder, but that feels wrong. I'm not sure if UrlSegment is the best way to go either, since I would basically be hacking the query string. Is there a way to format my request in the format I need using RestSharp's API?
What I ended up using is UrlSegment and then kept the .AddQueryParameter methods, so the final code block looks like :
var url = new RestClient(localhost/someapp/api/dosomething/{id});
var request = new RestRequest(Method.POST);
request.AddParameter("Id", "5335", ParameterType.UrlSegment);
request.AddQueryParameter("save", "true");
request.AddQueryParameter("UserId", "5355234");
Which produced the URI I needed.
The easiest coding process for using RestSharp or any other API client library would be to use Postman to generate if you are unsure of how to code it. Download Postman, do a new request, enter the URL string to send to the API, click on Code, select C# (RestSharp) from the dropdown. Here is the code it generated.
var client = new RestClient("http://localhost/someapp/api/dosomething /5335?save=false&userid=66462");
var request = new RestRequest(Method.POST);
request.AddHeader("Postman-Token", "bd05aa45-f1b9-4665-a3e7-888ad16f2800");
request.AddHeader("cache-control", "no-cache");
IRestResponse response = client.Execute(request);
In a particular case I need to be able to disable compression in the requst/response.
Using Firefox RestClient I am able to post some xml to a web service and get some response xml successfully with a single header parameter "Accept-Encoding" : " "
which if I do not set this header, the response body would come back compressed with some binary data in the response body(that's why I want to disable gzip in response)
Now using the same header value in my app (using RestSharp in C#), I still get the binary data (gzip) in response.
Can someone please shed some light? Is it supported in RestSharp?
RestSharp does not support disabling compression.
If you look at the source code in Http.Sync.cs line 267 (assuming a sync request, async has the same code duplicated in Http.Async.cs line 424)
webRequest.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip | DecompressionMethods.None;
that is, the underlying WebRequest that Restsharp uses to make the http call has the compression options hardcoded. There is an open issue that documents this
The feature (only just) seems to have been added, but stealthily - without a note on the issue's status nor on the changelogs. Possibly as it hasn't been sufficiently tested?
Nevertheless I recently had a need for this functionality and tested it - and it works. Just set the RestClient instance's AutomaticDecompression property to false.
If you intend to keep your RestClient instance long-lived remember to do this before its first use - the setting seems to be 'locked in' after use and cannot change after. In my case I needed to make calls with and without AutomaticDecompression so i simply created two different RestClient instances.
Using RestSharp v106.11.4, I was unable to turn off automatic decompression as Bo Ngoh suggested. I set the AutomaticDecompression on the RestClient instance at the moment it gets instantiated, but still the Accept-Encoding header was added.
The way to set this & disable the decompression is through the ConfigureWebRequest method, which is exposed on the RestClient. Below snippet allowed me to turn off this feature:
var client = new RestClient();
client.ConfigureWebRequest(wr =>
{
wr.AutomaticDecompression = DecompressionMethods.None;
});
Not sure if this relevant anymore, but for maybe future references
RestRequest has IList<DecompressionMethods> AllowedDecompressionMethods, and when creating new RestRequest the list is empty. Only when calling the Execute method it fills with the default values (None, Deflate, and GZip) unless it's not empty
To update the wanted decompression method, simply use the method named AddDecompressionMethod and add the wanted decompression method - and that's that
Example:
var client = new RestClient();
var request = new RestRequest(URL, Method.GET, DataFormat.None);
request.AddDecompressionMethod(DecompressionMethods.GZip);
var response = client.Execute(request);
As of RestSharp version 107, the AddDecompressionMethod has been removed and most of the client options has been move to RestClientOptions. Posting here the solution that worked for me, in case anyone needs it.
var options = new RestClientOptions(url)
{
AutomaticDecompression = DecompressionMethods.None
};
_client = new RestClient(options);
I am trying to send an HTTP GET request in VBA which includes a cookie containing a colon character, like so:
objReq.Open "GET", "http://my.url.com?foo=bar", False
objReq.setRequestHeader "Cookie", "abcd=cookie:containing:colons"
objReq.Send
Depending on what object type I use for objReq, however the request gets treated differently.
The following object type works:
Dim objReq As MSXML2.ServerXMLHTTP
Set objReq = New MSXML2.ServerXMLHTTP
Unfortunately, I need to use a different object type (as MSXML2.ServerXMLHTTP can't capture sufficient detail about HTTP redirects). From what I've read, I need to use Winhttp.WinHttpRequest, MSXML2.ServerXMLHTTP40, or MSXML2.ServerXMLHTTP60, but using any of those objects results in the following error when including colons in the cookie value.
I have tried replacing the colons with Chr(58), %3A, and double-quoting within the string to no avail. I have also tried adding a 'Content-Type' header with various character encodings, but that doesn't seem to work either.
Anyone know how I can send a cookie value containing colons using the Winhttp.WinHttpRequest, MSXML2.ServerXMLHTTP40, or MSXML2.ServerXMLHTTP60 objects?
PS: Alternatively, if anyone knows how I can get the ending URL of a redirect sequence when using MSXML2.ServerXMLHTTP, that would work as well! Winhttp.WinHttpRequest would allow me to capture a 302 status code, and MSXML2.ServerXMLHTTP40 or MSXML2.ServerXMLHTTP60 would allow me to use GetOption(-1), but MSXML2.ServerXMLHTTP doesn't support either of these methods (from what I can tell).
I did a bit of testing with WinHttpRequest and I came up with the following code:
Dim objReq As WinHttp.WinHttpRequest
Set objReq = New WinHttp.WinHttpRequest
objReq.Option(WinHttpRequestOption_EnableRedirects) = True
objReq.Open "GET", "http://www.example.com", False
objReq.setRequestHeader "Cookie", "abcd=cookie:containing:colons"
objReq.send
I did notice i got the same error that you posted when I forgot to include the "http://" in the url.
I hope this helps!
httpclient, httpmime 4.1.3
I am trying to upload a file through http to a remote server with no success.
Here's my code:
HttpPost method;
method = new HttpPost(solrUrl + "/extract");
method.getParams().setParameter("literal.id", fileId);
method.getParams().setBooleanParameter("commit", true);
MultipartEntity me = new MultipartEntity();
me.addPart("myfile", new InputStreamBody(doubleInput, contentType, fileId));
method.setEntity(me);
//method.setHeader("Content-Type", "multipart/form-data");
HttpClient httpClient = new DefaultHttpClient();
HttpResponse hr = httpClient.execute(method);
The server is Solr.
This is to replace a working bash script that calls curl like this,
curl http://localhost:8080/solr/update/extract?literal.id=bububu&commit=true -F myfile=#bububu.doc
If I try to set "Content-Type" "multipart/form-data", the receiving part says that there's no boundary (which is true):
HTTP Status 500 - the request was rejected because no multipart boundary was found
If I omit this header setting, the server issues an error description that, as far as I discovered, indicates that the content type was not multipart [2]:
HTTP Status 400. The request sent by the client was syntactically incorrect ([doc=null] missing required field: id).
This is related to [1] but I couldn't determine the answer from it. I was wondering,
I am in the same situation but didn't understand what to do. I was hoping that the MultipartEntity would tell the HttpPost object that it is multipart, form data and have some boundary, and I wouldnt set content type by myself. I didn't quite get how to provide boundaries to the entities - the MultipartEntity doesn't have a method like setBoundary. Or, how to get that randomly generated boundary to specify it in addHeader by myself - no getBoundary methor either...

[2] http://lucene.472066.n3.nabble.com/Updating-the-index-with-a-csv-file-td490013.html
I am suspicious of
method.getParams().setParameter("literal.id", fileId);
method.getParams().setBooleanParameter("commit", true);
In the first line, is fileId a string or file pointer (or something else)? I hope it is a string. As for the second line, you can rather set a normal parameter.
I am trying to tackle the HTTP Status 400. I dont know much Java (or is that .Net?)
