Uploading files with HTTP PUT

[tsuna123]

How do i use HTTP PUT to upload files?

Im using C# code to send the request

var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
"link",
"",
"application/x-www-form-urlencoded",
instance.GetProxy(),
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.HeaderAndBody,
AdditionalHeaders: new []{"Authorization:Bearer " + oauth" }
);

return response;

how do i upload files with this?
or is there a better alternative?

Thanks in advance

It's the same as POST with multipart:

var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
"https://httpbin.org/put",
@"-----------------------------77748066757751
Content-Disposition: form-data; name=""file""; filename=""cat.jpg""
Content-Type: image/jpeg

C:\Downloads\multipart\cat.jpg
-----------------------------77748066757751--",
"multipart/form-data",
"",
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.BodyOnly
);
return response;

var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
project.Variables["url_upload"].Value,
@"-----------------------------77748066757751

Content-Type: application/x-rar-compressed

C:\папка\папка\123.rar
-----------------------------77748066757751--",

ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.BodyOnly
);
return response;

Использую данный код, в яндекс диск rest api, rar создаётся, но не закачивается.
При скачивании битый архив. В чём может быть проблема? С txt та же беда, создаётся новый файл с текстом директории (C:\папка\папка\123.txt).
Хотя в файле 123.txt - лежит другой текст

Спойлер: SDK яндекс апи

Thanks for the help but i dont think its working for me...

When i check the request traffic, this is what the request body looks like when i do it on the website

Спойлер: Normal

This is what the request body looks like when i try it with the code

Спойлер: Code

Doesnt look like the file is being chosen properly?

Also,

@"-----------------------------77748066757751
-----------------------------77748066757751--",

What do these parts mean?

How do you encode a file in your request? In bytes?

Sorry im kinda noob at this, not sure what that means or how to find out

can you show me how i can take a image link convert to Bytes and upload it using the PUT request like the one u showed above ?

string Url = "https://image_link";
using (var webClient = new System.Net.WebClient()) {
byte[] imageBytes = webClient.DownloadData(Url);

}

var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
"https://httpbin.org/put",
imageBytes[0],
"multipart/form-data",
"",
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.BodyOnly
);
return response;

Here are examples on how to convert image to bytes - https://stackoverflow.com/questions/3801275/how-to-convert-image-to-byte-array
You may convert image like this instead of webclient:

byte[] mageBytes  = System.IO.File.ReadAllBytes(HttpContext.Current.Server.MapPath(path));

@VladZen please help me with this last part ive been trying for a while but no luck

I don't quite understand what problem you have...
This code converts the image to bytes automatically. all you need is just insert link to image at the beginning.
And put the link to website where to upload image in var response string.

string Url = "https://image_link";
using (var webClient = new System.Net.WebClient()) {
byte[] imageBytes = webClient.DownloadData(Url);

}

var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
"https://httpbin.org/put",
imageBytes[0],
"multipart/form-data",
"",
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.BodyOnly
);
return response;

return response;

i tried running that code but is is not runable,
this is what is says in the log "
Compile code of Error in action "CS0103" "The name 'imageBytes' does not exist in the current context". [Row: 9; Column: 1]
"

byte[] imageBytes;
string Url = "https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png";
using (var webClient = new System.Net.WebClient()) {
imageBytes = webClient.DownloadData(Url);
}

var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
"https://httpbin.org/put",
imageBytes[0],
"multipart/form-data",
"",
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.BodyOnly
);
return response;

So i declared imageBytes outside but i am still geting error message:

Compile code of Error in action "CS1502" "The best overloaded method match for 'ZennoLab.CommandCenter.ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod, string, string, string, string, string, ZennoLab.InterfacesLibrary.Enums.Http.ResponceType, int, string, string, bool, int, string[], string, bool, bool, ZennoLab.InterfacesLibrary.ProjectModel.ICookieContainer)' has some invalid arguments".

Something wrong with arguments in this method... - https://help.zennolab.com/en/v5/zennoposter/5.27.0.0/topic758.html

назрела аналогичная проблема. Удалось как-то ее победить? Нейронку выдрочил, но она также не может родить рабочего решения, даже на коде.
Upd: решение найдено...

Если что, то получилось решить задачу по загрузке файла на я.диск по апи только через curl:

// Параметры
string filePath = project.Directory + @"\file\" + project.Variables["temp"].Value;
string uploadUrl = project.Json.href.ToString(); // полученный get-запросом url для загрузки файла

// Формируем команду curl с выводом заголовков
string curlCmd = $"curl -i -T \"{filePath}\" \"{uploadUrl}\"";

// Запуск процесса
var proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = "cmd.exe";
proc.StartInfo.Arguments = "/C " + curlCmd;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = true;
proc.Start();

string output = proc.StandardOutput.ReadToEnd();
string error = proc.StandardError.ReadToEnd();
proc.WaitForExit();

// Формируем полный ответ
string fullResponse = "=== STDOUT ===\n" + output + "\n\n=== STDERR ===\n" + error;

// Логирование результата
project.SendInfoToLog("Ответ curl:", true);
project.SendInfoToLog(fullResponse, true);

// Сохраняем полный ответ в переменную
project.Variables["api_response"].Value = fullResponse;

// Проверка результата
if (proc.ExitCode == 0)
{
    project.SendInfoToLog("✓ Файл отчета загружен через curl!", true);
    
    // Извлекаем код ответа из заголовков
    if (output.Contains("HTTP/1.1 201 Created"))
    {
        project.SendInfoToLog("Код ответа: 201 Created", true);
        
        // Извлекаем Location из заголовков
        string[] lines = output.Split('\n');
        foreach (string line in lines)
        {
            if (line.StartsWith("Location:"))
            {
                string location = line.Substring(9).Trim();
                project.SendInfoToLog("Файл сохранен по пути: " + Uri.UnescapeDataString(location), true);
                break;
            }
        }
    }
}
else
{
    project.SendInfoToLog("ОШИБКА загрузки через curl! Код: " + proc.ExitCode, true);
}
