J'essaie de créer une API Web Asp.net pour poster des fichiers. J'ai trouvé l'exemple suivant dans https://code.msdn.microsoft.com/AngularJS-with-Web-API-22f62a6eTéléchargement d'un fichier et enregistrement des valeurs de saisie de texte en un clic?
La méthode API Web est:
[RoutePrefix("api/photo")]
public class PhotoController : ApiController
{
private IPhotoManager photoManager;
public PhotoController()
: this(new LocalPhotoManager(HttpRuntime.AppDomainAppPath + @"\Album"))
{
}
public PhotoController(IPhotoManager photoManager)
{
this.photoManager = photoManager;
}
// GET: api/Photo
public async Task<IHttpActionResult> Get()
{
var results = await photoManager.Get();
return Ok(new { photos = results });
}
// POST: api/Photo
public async Task<IHttpActionResult> Post()
{
// Check if the request contains multipart/form-data.
if(!Request.Content.IsMimeMultipartContent("form-data"))
{
return BadRequest("Unsupported media type");
}
try
{
var photos = await photoManager.Add(Request);
return Ok(new { Message = "Photos uploaded ok", Photos = photos });
}
catch (Exception ex)
{
return BadRequest(ex.GetBaseException().Message);
}
}
Et le code fichier Uploader html. (J'ai ajouté une entrée de texte <input type="text" id="test" value="testit" />
pour le test
<form name="newPhotosForm" role="form" enctype="multipart/form-data" ng-disabled="appStatus.busy || photoManagerStatus.uploading">
<div class="form-group" ng-hide="hasFiles">
<label for="newPhotos">select and upload new photos</label>
<input type="file" id="newPhotos" class="uploadFile" accept="image/*" eg-files="photos" has-files="hasFiles" multiple>
<input type="text" id="test" value="testit" /> <!--- Added a text input for test -->
</div>
<div class="form-group" ng-show="hasFiles && !photoManagerStatus.uploading">
<ul class="list-inline">
<li><strong>files:</strong></li>
<li ng-repeat="photo in photos"> {{photo.name}}</li>
</ul>
<input class="btn btn-primary" type="button" eg-upload="upload(photos)" value="upload">
<input class="btn btn-warning" type="reset" value="cancel" />
</div>
<div class="form-group" ng-show="photoManagerStatus.uploading">
<p class="help-block">uploading</p>
</div>
</form>
Le JS upload
Fonction:
function upload(photos)
{
service.status.uploading = true;
appInfo.setInfo({ busy: true, message: "uploading photos" });
var formData = new FormData();
angular.forEach(photos, function (photo) {
formData.append(photo.name, photo);
});
return photoManagerClient.save(formData)
.$promise
.then(function (result) {
if (result && result.photos) {
result.photos.forEach(function (photo) {
if (!photoExists(photo.name)) {
service.photos.push(photo);
}
});
}
appInfo.setInfo({message: "photos uploaded successfully"});
return result.$promise;
},
function (result) {
appInfo.setInfo({message: "something went wrong: " + result.data.message});
return $q.reject(result);
})
['finally'](
function() {
appInfo.setInfo({ busy: false });
service.status.uploading = false;
});
}
Cependant, il semble que la valeur de l'entrée ajoutée test
ne peut pas être transmise au code API Web?
