I'm try to upload a file to the shared folder...
This is my code.
// using httpclient-4.5
Path filePath = Paths.get("C:/afile.txt");
String ticket = getTicket(); // get a ticket via /alfresco/service/api/login...
CloseableHttpClient client = HttpClients.createDefault();
HttpPost post = new HttpPost("http://localhost:8080/alfresco/service/api/upload?alf_ticket=" + ticket);
MultipartEntityBuilder entity = MultipartEntityBuilder.create();
StringBody descriptionBody = new StringBody("a test", ContentType.TEXT_PLAIN);
StringBody siteId = new StringBody("company_home", ContentType.TEXT_PLAIN); // how can upload the file
StringBody containerid = new StringBody("/Shared", ContentType.TEXT_PLAIN); // in the shared folder??
entity.addBinaryBody("filedata", filePath.toFile());
entity.addPart("siteid", siteId);
entity.addPart("containerid", containerid);
post.setEntity(entity.build());
CloseableHttpResponse postResponse = client.execute(post);
// ...
Can anyone help me? Thanks.

I am trying to upload an image file as ByteArrayContent through my web service. I have added all the images to the shared project and set the build action as Embedded resource.
Following is my code:
var fileBytes = File.ReadAllBytes("Avatars." + selectedAvatar);
var byteContent = new ByteArrayContent(fileBytes);
content.Add(byteContent, "file", selectedAvatar);
When I try like above I am getting System.IO.FileNotFoundException: Could not find file "/Projectname.Avatars.ic_avatar01_xx.png"
Added the images directly inside a folder in the shared project like the below screenshot.
:
I tried changing the . with a / in the file path, like below:
var fileBytes = File.ReadAllBytes("Avatars/" + selectedAvatar);
var byteContent = new ByteArrayContent(fileBytes);
content.Add(byteContent, "file", selectedAvatar);
But in that case, I am getting the System.IO.DirectoryNotFoundException: Could not find a part of the path "/Avatars/ic_avatar01_xx.png"
What is the correct way to get the path of an image file stored on a shared project?
Also tried another approach:
string avatarFileName = "Avatars/" + selectedAvatar;
var assembly = typeof(ProfilePage).GetTypeInfo().Assembly;
var stream = assembly.GetManifestResourceStream($"{assembly.GetName().Name}.{avatarFileName}");
content.Add(stream, "file", avatarFileName);
But in the above case I am getting the below error:
If you want to upload the image with Stream , you could check the following code
private async Task<string> UploadImage(Stream FileStream)
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://your.url.com/");
MultipartFormDataContent form = new MultipartFormDataContent();
HttpContent content = new StringContent("fileToUpload");
form.Add(content, "fileToUpload");
content = new StreamContent(FileStream);
content.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
{
Name = "fileToUpload",
FileName = "xxx.png"
};
form.Add(content);
var response = await client.PostAsync("http://your.url.com/", form);
return response.Content.ReadAsStringAsync().Result;
}
Option 2:
You could also use the plugin FileUploaderPlugin . It support uploading multiple files at once
Uploading from a file path
CrossFileUploader.Current.UploadFileAsync("<URL HERE>", new FilePathItem("<REQUEST FIELD NAME HERE>","<FILE PATH HERE>"), new Dictionary<string, string>()
{
{"<HEADER KEY HERE>" , "<HEADER VALUE HERE>"}
}
);
Option 3:
The first parameter of MultipartFormDataContent is HttpContent. To handle the stream, try using the StreamContent type which inherits from the HttpContent. Get the streamContent from the stream and add id to the MultipartFormDataContent.
string avatarFileName = "Avatars." + selectedAvatar;
var assembly = typeof(ProfilePage).GetTypeInfo().Assembly;
var stream = assembly.GetManifestResourceStream($"{assembly.GetName().Name}.{avatarFileName}");
var streamContent = new StreamContent(stream);
content.Add(streamContent, "file", avatarFileName);
Based on the doc from MS https://learn.microsoft.com/en-us/sharepoint/dev/sp-add-ins/using-csom-for-dotnet-standard, Save/OpenBinaryDirect methods is not available for .NET core app, they suggest to use regular file API, so what is the alternative way to read/write files stored in SharePoint online? what is the regular file API? does anyone done this? any example code/documentation?
Download file in .NET Core CSOM:
using (var authenticationManager = new AuthenticationManager())
using (var context = authenticationManager.GetContext(site, user, password))
{
context.Load(context.Web, p => p.Title);
context.ExecuteQuery();
Microsoft.SharePoint.Client.File file = context.Web.GetFileByUrl("https://tenant.sharepoint.com/sites/michael/Shared%20Documents/aa.txt");
context.Load(file);
context.ExecuteQuery();
string filepath = #"C:\temp\" + file.Name;
Microsoft.SharePoint.Client.ClientResult<Stream> mstream = file.OpenBinaryStream();
context.ExecuteQuery();
using (var fileStream = new System.IO.FileStream(filepath, System.IO.FileMode.Create))
{
mstream.Value.CopyTo(fileStream);
}
using (System.IO.StreamReader sr = new System.IO.StreamReader(mstream.Value))
{
String line = sr.ReadToEnd();
Console.WriteLine(line);
}
}
Upload file in .NET Core CSOM:
string filepath = #"C:\temp\aa.txt";
FileCreationInformation newfile = new FileCreationInformation();
newfile.Url = System.IO.Path.GetFileName(filepath);
newfile.Content= System.IO.File.ReadAllBytes(filepath);
List library = context.Web.Lists.GetByTitle("Documents");
Microsoft.SharePoint.Client.File uploadFile = library.RootFolder.Files.Add(newfile);
context.Load(uploadFile);
context.ExecuteQuery();
Jerry's answer got me there, but I wanted to add a couple of extras that weren't mentioned in his answer.
If your file destination isn't the main Documents list, instead of the Lists.GetByTitle call use
var folder = context.Web.GetFolderByServerRelativeUrl(...);
File uploadFile = folder.Files.Add(newfile);
If you're updating a file, you've got to set
newFile.Overwrite = true;
And if the file you're uploading/replacing is greater than 2MB, you've got to use the ContentStream instead of Content
FileCreationInformation newfile = new FileCreationInformation
{
Url = relativeUrl,
ContentStream = stream,
Overwrite = true
};
I am trying to upload an image from ASP.NET to S3. I am using AWS SDK for that and have already set up what is needed. However, after i run my project, i received an error. I'll be replacing my bucket name to ... for this sample code.
I set up my secretkey and accesskey from User in my Web.config. Please do tell me if u need more codes. I need help.
controller
private static readonly string _awsAccessKey = ConfigurationManager.AppSettings["AWSAccessKey"];
private static readonly string _awsSecretKey = ConfigurationManager.AppSettings["AWSSecretKey"];
[HttpPost]
public ActionResult UploadFile(HttpPostedFileBase file)
{
try
{
if (file.ContentLength > 0)
{
IAmazonS3 client;
using (client = Amazon.AWSClientFactory.CreateAmazonS3Client(_awsAccessKey, _awsSecretKey))
{
PutObjectRequest request = new PutObjectRequest
{
BucketName = "...",
CannedACL = S3CannedACL.PublicRead,
Key = "images/" + (DateTime.Now.ToBinary() + "-" + file.FileName),
FilePath = Server.MapPath("~/UploadedFiles")
};
client.PutObject(request);
}
}
imageUrls = "File Uploaded Successfully!!";
System.Diagnostics.Debug.WriteLine("File Uploaded Successfully!!");
return Json(imageUrls);
}
catch
{
ViewBag.Message = "File upload failed!!";
System.Diagnostics.Debug.WriteLine("File upload failed!!");
return Json(ViewBag.Message);
}
}
You're getting the error due to DateTime.Now.ToBinary() which contains invalid characters to be used in a URL. For example, you could use a GUID or a Unix timestamp instead.
Also, the FilePath property you're assigning to the PutObjectRequest is the full path and name to a file to be uploaded. So, you don't need it when you already have HttpPostedFileBase as an input parameter, which contains the InputStream property (i.e., the stream object).
Your PutObjectRequest should look something like this:
.
.
.
Guid guid = Guid.NewGuid();
// Create a client
AmazonS3Client client = new AmazonS3Client(_awsAccessKey, _awsSecretKey);
// Create a PutObject request
PutObjectRequest request = new PutObjectRequest
{
BucketName = "...",
CannedACL = S3CannedACL.PublicRead,
Key = "images/" + guid + "-" + file.FileName
};
using (System.IO.Stream inputStream = file.InputStream)
{
request.InputStream = inputStream;
// Put object
PutObjectResponse response = client.PutObject(request);
}
.
.

I finally solved it. I realized i did not place region in AWSClientFactory, right at the end after the keys.
I wish to get the data of Google analytics via service account.
When I launch first time the application, everything works correctly and I have access to the data. But When I launch second time the application I have the following error which appears: " the system cannot find the path specified ". Have you an idea? I thought it can be a lock.
This is my source code:
public static String GetAccessToken(string clientIdEMail, string keyFilePath, String scope)
{
// certificate
var certificate = new X509Certificate2(keyFilePath, "notasecret", X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.Exportable);
// header
var header = new { typ = "JWT", alg = "RS256" };
// claimset
var times = GetExpiryAndIssueDate();
var claimset = new
{
iss = clientIdEMail,
scope = scope,
aud = "https://accounts.google.com/o/oauth2/token",
iat = times[0],
exp = times[1],
};
JavaScriptSerializer ser = new JavaScriptSerializer();
// encoded header
var headerSerialized = ser.Serialize(header);
var headerBytes = Encoding.UTF8.GetBytes(headerSerialized);
var headerEncoded = Convert.ToBase64String(headerBytes);
// encoded claimset
var claimsetSerialized = ser.Serialize(claimset);
var claimsetBytes = Encoding.UTF8.GetBytes(claimsetSerialized);
var claimsetEncoded = Convert.ToBase64String(claimsetBytes);
// input
var input = headerEncoded + "." + claimsetEncoded;
var inputBytes = Encoding.UTF8.GetBytes(input);
// signiture
var rsa = certificate.PrivateKey as RSACryptoServiceProvider;
var cspParam = new CspParameters
{
KeyContainerName = rsa.CspKeyContainerInfo.KeyContainerName,
KeyNumber = rsa.CspKeyContainerInfo.KeyNumber == KeyNumber.Exchange ? 1 : 2,
Flags = CspProviderFlags.UseMachineKeyStore
};
var aescsp = new RSACryptoServiceProvider(1024,cspParam) { PersistKeyInCsp = false };
var signatureBytes = aescsp.SignData(inputBytes, "SHA256");
var signatureEncoded = Convert.ToBase64String(signatureBytes);
// jwt
var jwt = headerEncoded + "." + claimsetEncoded + "." + signatureEncoded;
var client = new WebClient();
client.Encoding = Encoding.UTF8;
var uri = "https://accounts.google.com/o/oauth2/token";
var content = new NameValueCollection();
content["assertion"] = jwt;
content["grant_type"] = "urn:ietf:params:oauth:grant-type:jwt-bearer";
string response = Encoding.UTF8.GetString(client.UploadValues(uri, "POST", content));
JsonGoogleResponse result = (ser.Deserialize<JsonGoogleResponse>(response));
return result.access_token;
}

If you are running in IIS, you need to set "Load User Profile" to True in the application pool's advanced settings to be able to load a cert by filename & password.
So, I just had the exact same problem. I tried to solve it for almost 4 hours.
Problem was in passed path to key. Because I used the code from Google sample console application, where the path was just "key.p12" and the key was in the same directory as the exe file.
And when I wanted to create MVC application, I did not realize, that root of virtual server path can not be called just like "key.p12".
SOLUTION
Double check the path to the key. If it is MVC application (or another ASP web), then add the key file to the root and in code call the key by using Server.MapPath("key.p12").
I just had the same issue, in my case it was a space in the path. I have no idea why, but when I put the p12 file on c:\ root, it's working...
I have a requirement where I need to download binary file of a multimedia component but when I access the properties exposed of BinaryContentData class then there is no property to download an image file. Although for uploading file, Core Service have a property namely UploadFromFile.
So is there a way to download binary file to a temp location. Below is the code I am using:
core_service.ServiceReference1.SessionAwareCoreService2010Client client = new SessionAwareCoreService2010Client();
client.ClientCredentials.Windows.ClientCredential.UserName = "myUserName";
client.ClientCredentials.Windows.ClientCredential.Password = "myPassword"; client.Open();
ComponentData component = (ComponentData)client.TryCheckOut(
multimediaComponentURI, new ReadOptions());
BinaryContentData binaryData = component.BinaryContent;
Please Suggest.
There is a helper function called streamDownloadClient.DownloadBinaryContent inside Tridion.ContentManager.CoreService.Client.dll that you can use.
I have created the following function that I usually reuse for that purpose:
private static void CreateBinaryFromMultimediaComponent(string tcm)
{
Tridion.ContentManager.CoreService.Client.StreamDownloadClient streamDownloadClient = new StreamDownloadClient();
SessionAwareCoreServiceClient client = new SessionAwareCoreServiceClient("netTcp_2011");
ComponentData multimediaComponent = client.Read(tcm, new ReadOptions()) as ComponentData;
// Generate you own file name, and file location
string file = "D:\\MyTempLocation\\" + Path.GetFilename(multimediaComponent.BinaryContent.Filename);;
// Write out the existing file from Tridion
FileStream fs = File.Create(file);
byte[] binaryContent = null;
if (multimediaComponent.BinaryContent.FileSize != -1)
{
Stream tempStream = streamDownloadClient.DownloadBinaryContent(tcm);
var memoryStream = new MemoryStream();
tempStream.CopyTo(memoryStream);
binaryContent = memoryStream.ToArray();
}
fs.Write(binaryContent, 0, binaryContent.Length);
fs.Close();
}
