HTTP PUT pour télécharger un fichier en Java

Question

Edit : Je crois que j'ai trouvé comment faire la partie données binaires. Vérifiez-le dans le code, mais je suis presque sûr que j'ai compris. Maintenant, j'obtiens une nouvelle erreur lorsque j'essaie de compléter le téléchargement comme décrit dans l'aide en ligne. Documentation sur l'API de Vimeo

Edit 2 : Ajout de .debug() à OAuthService et mise à jour de la sortie.

Question originale : J'essaye de télécharger une vidéo sur Vimeo en utilisant la fonction API Vimeo (méthode de diffusion en continu) . J'utilise scribe pour autoriser mon application, obtenir mon jeton d'accès et préparer le téléchargement de la vidéo. Je ne sais pas quoi faire au moment où la documentation de l'API Vimeo dit "données binaires de votre fichier ici" dans cet exemple de requête HTTP pour le PUT :

PUT http://1.2.3.4:8080/upload?ticket_id=abcdef124567890 HTTP/1.1

Hôte : 1.2.3.4:8080

Content-Length : 339108

Content-Type : video/mp4

.... données binaires de votre fichier ici ....

Je peux obtenir le ticket et les en-têtes sans problème. C'est juste que, que dois-je faire pour insérer les données binaires de mon fichier ?

Notes :

• Il s'agit d'une application de bureau en Java
• C'est un petit fichier vidéo que je teste.

Voici mon code pour le put (rappelez-vous, j'utilise scribe )

// Setup File (line 52)
File testUp = new File("C:/Users/Kent/Desktop/test.mp4");
String contentLength = Long.toString(testUp.length());
System.out.println("The content length is: " + contentLength);
byte[] fileBytes = ByteStreams.toByteArray(new FileInputStream(testUp));

// Upload file (line 58)
request = new OAuthRequest(Verb.PUT, endpoint);
request.addHeader("Content-Length", contentLength);
request.addHeader("Content-Type", "video/mp4");
request.addPayload(fileBytes);
response = signSendAndPrint(service, accessToken, request, "Upload PUT: " + endpoint);

// Check response code is valid (line 65)
if (response.getCode() != 200) {
  System.out.println("The response was not 200! It was: " + response.getCode());
  return;
}

// Verify the upload (line 71)
request = new OAuthRequest(Verb.PUT, endpoint);
request.addHeader("Content-Length", "0");
request.addHeader("Content-Range", "bytes */*");
response = signSendAndPrint(service, accessToken, request, "Verify Upload PUT: " + endpoint);

// Check response code is valid (line 77)
if (response.getCode() != 308) {
  System.out.println("The response was not 308! It was: " + response.getCode());
  return;
}

// Complete Upload (line 83)
request = new OAuthRequest(Verb.PUT, endpoint);
request.addQuerystringParameter("method", "vimeo.videos.upload.complete");
Response completeResponse = signSendAndPrint(service, accessToken, request, "complete"); // This is line 86, it's the second to top level of my code that breaks the process.

//Set video info (line 88)
setVimeoVideoInfo(completeResponse, service, accessToken, vimeoAPIURL);
  }

  private static Response signSendAndPrint(OAuthService service, Token accessToken, OAuthRequest request, String description) {
    service.signRequest(accessToken, request);
    printRequest(request, description + " Request");
    Response response = request.send(); //This is line 105. It's the top level of my code that breaks the process
    printResponse(response, description + " Response");
    return response;
  }

Answer 1

Vous devez ajouter deux autres paramètres lorsque vous terminez le téléchargement. Documentation sur l'API de Vimeo indique que vous avez besoin de trois paramètres pour vimeo.videos.upload.complete : filename, oauth_token et ticket_id. scribe se charge du oauth_token pour vous.

De plus, vous devez appeler le point de terminaison original, et non celui obtenu lors de la demande de ticket.
