format.js生成406不可接受误差

Question

可能重复：
Weird “406 not acceptable” error

下面的代码生成一个406不可接受错误。

我的代码有什么问题？

def remote_create 
    @photo = Photo.new(params[:photo]) 

    respond_to do |format| 
     if @photo.save 
     # add @photo's thumbnail to last import tag 
     format.js { 
      render :update do |page| 
      page.insert_html :bottom, 'polaroids' , :partial => 'polaroid', :locals => {:photo => @photo} 
      end 
     } 
     else 
     format.html 
     end 
    end 
    end

Answer 1

我找到了解决办法，当我建立Ajax请求，我需要设置该参数之前设置下面的头参数

xhr.setRequestHeader("Accept", "text/javascript"); 

，请求头是

Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 

现在请求标题看起来像这样

Accept text/javascript 

现在正常工作

更新咕：

下面是完整的代码，该setRequestHeader是在发送功能

希望它有助于

在我看来

<%= link_to 'upload all', '/photos/remote_create', :remote => true, :method => 'POST', :multipart => 'droppedItems', :id => 'upload', :class => 'awesome small green' %> 

在rails.js function handleRemote（element）

else if (element.readAttribute('multipart') != null) { 
    url = element.readAttribute('data-url') || element.readAttribute('href'); 
    var uploader = new Uploader(null, $(element.readAttribute('multipart'))); 
    uploader.sendFiles(url); 
    return; 
} 

在一个js实用程序文件

sendFiles : function(url) { 
    try { 
     this.filesToUpload.forEach(function(file, index, all) { 
      send(file, url); 
     }); 
    } catch(e) { 
     alert('send Error: ' + e); 
    } 
} 

function send(file, url) { 
    try { 
     var xhr = new XMLHttpRequest; 

     var boundary = generateBoundary(); 

     var contentType = "multipart/form-data; boundary=" + boundary; 

     xhr.upload.addEventListener("loadstart", (function(e){ 
      $('progress_'+file.name).update('0%'); 
     }), false); 

     xhr.upload.addEventListener("progress", (function(e) { 
       if (e.lengthComputable) { 
        var percentage = Math.round((e.loaded * 100)/e.total); 
        $('progress_'+file.name).update(percentage + '%'); 
       } 
     }), false); 

     xhr.onreadystatechange = function() { 
      if (xhr.readyState === 4) { 
       eval(xhr.responseText || ''); 
      } 
     }; 

     xhr.open("POST", url, true); 

     xhr.setRequestHeader("Content-Type", contentType); 
     xhr.setRequestHeader("Accept", "text/javascript"); 

     var CRLF = "\r\n"; 
     var request = "--" + boundary + CRLF; 

     request += 'Content-Disposition: form-data; '; 
     request += 'name="' + 'photo[name]' + '"' + CRLF + CRLF; 
     request += file.name + CRLF; 

     request += "--" + boundary + CRLF; 

     request += 'Content-Disposition: form-data; '; 
     request += 'name="' + 'photo[photo]' + '"; '; 
     request += 'filename="'+ file.fileName + '"' + CRLF; 

     request += "Content-Type: application/octet-stream" + CRLF + CRLF; 
     request += file.value + CRLF; 
     request+= "--" + boundary + "--" + CRLF; 

     xhr.sendAsBinary(request); 

    } catch(e) { 
     alert('send Error: ' + e); 
    } 
}

你要为特定的格式（例如，如果使用jQuery，像{format: 'raw'}），或设置请求头MIME类型（搜索setRequestHeader）？

最容易找到的方法是使用Firebug并查看您的请求的样子。

要尝试的其他事情，与另一个浏览器发生同样的错误？
