각도가

Question

인 파일을 업로드 할 때 HttpPostedFileBase가 null입니다. Angular를 MVC와 함께 사용합니다. 파일을 업로드 할 때 HttpPostedFileBase은 null입니다.

HTML :

<input type="file" data-ng-model="fileName" onchange="angular.element(this).scope().fileInputChanged(this)"> 

각도 :

scope.fileInputChanged = function (element) { 
    scope.$apply(function (scope) { 
     console.log('files:', element.files); 

     _.each(element.files, function (element, index, list) { 
      scope.files.push(element); 
     }); 
    }); 
} 

scope.uploadDocuments = function() { 
    var formData = new FormData(); 

    // add uploaded files to form data object 
    for(var i in scope.files){ 
     formData.append("uploadedFile", scope.files[i]); 
    } 

    // create xml http request object 
    var httpRequest = new XMLHttpRequest(); 
    httpRequest.upload.addEventListener("progress", uploadProgress, false); 
    httpRequest.addEventListener("load", uploadComplete, false); 
    httpRequest.addEventListener("error", uploadFailed, false); 
    httpRequest.addEventListener("abort", uploadCanceled, false); 
    httpRequest.open("POST", "/Customer/UploadDocuments"); 

    // make progress bar visible 
    scope.progressVisible = true; 

    // send the request to the server with the form data 
    httpRequest.send(formData); 
} 

// Private functions 
function uploadProgress(event) { 
    scope.$apply(function() { 
     if (event.lengthComputable) { 
      scope.progressValue = Math.round(event.loaded * 100/event.total); 
     } 
     else { 
      scope.progressValue = "Kan progressie niet berekenen"; 
     } 
    }); 
} 

function uploadComplete(event) { 
    scope.hideForm(false); 
} 

function uploadFailed(event) { 
    alert("Het uploaden van de documenten is mislukt."); 
} 

function uploadCanceled(event) { 
    scope.$apply(function() { 
     scope.progressVisible = false; 
    }); 
}

public void UploadDocuments(HttpPostedFileBase file) 
{

내가이 작업을하려면 어떻게해야합니까?

Answer 1

양식 데이터의 이름을 uploadedFile으로 지정했기 때문에 그 작업은 file이라는 매개 변수를 사용합니다. 다음과 같이 매개 변수 이름을 변경하십시오.

public void UploadDocuments(HttpPostedFileBase uploadedFile) 
{ 
}
