Using php to check MIME type of file uploaded via form

匆匆过客 提交于 2019-12-11 03:33:55
问题 Ok, so I'm creating a website that will let users upload csv-files that are to be scanned in to a mySQL-databse. Because I don't want to risk evil people uploading strange files that can mess with my database I'm guessing it's a good idea to check the mime type of the file. From other threads I've understood that the only way to properly do this is by using finfo(). But I don't get it to work. The following code in my uploadfile.php just prints out the temporary file name followed by "hello".

How can I prevent user-agents from presenting a download window for unrecognized mime types?

问题 If you set the Content-Disposition header to attachment , this causes user-agents to always present a download window for that file. I would like to do this opposite of this: force user-agents to always display the response directly. In this particular case, I have an API that's sending JSON. I'd like to serve it as application/json as indicated by the specification, but since user-agents typically don't recognize the mime type, they present a download window. This makes debugging a real pain

getting base64 content string of an image from a mimepart in Java

问题 I am trying to get the base64 content of a MimePart in a MimeMultiPart, but I'm struggling with the Javamail package. I simply want the base64 encoded String of a certain inline image, there doesn't seem to be an easy way to do this though. I wrote a method that will take the mime content (as a string) and an image name as a parameter, and searches for the part that contains the base64 content of that image name, and in the end returns this base64 string (as well as the content type but that

问题 Trying to get photo to upload but can't get the file data to the server. The app brings up the camera and does a POST to the server but there is never any file uploaded. I've created the simplest app I could to test this at https://github.com/dustinb/Camera/blob/master/index.html. When the upload happens there is only 452 bytes sent to the server. 73.3.252.133 - - [04/Dec/2014:23:55:11 +0000] "POST /upload HTTP/1.1" 200 452 "-" "Dalvik/1.4.0 (Linux; U; Android 2.3.4; ADR6400L Build/GRJ22)" I

Overriding a MIME type in Rails

一笑奈何 提交于 2019-12-10 21:20:37
问题 I want to override the JSON MIME type ("application/json") in Rails to ("text/x-json"). I tried to register the MIME type again in mime_types.rb but that didn't work. Any suggestions? Thanks. 回答1: This should work (in an initializer, plugin, or some similar place): Mime.send(:remove_const, :JSON) Mime::Type.register "text/x-json", :json 回答2: Try: render :json => var_containing_my_json, :content_type => 'text/x-json' 来源: https://stackoverflow.com/questions/95554/overriding-a-mime-type-in-rails

Set / Change MIME type of iFrame?

别说谁变了你拦得住时间么 提交于 2019-12-10 21:05:47
问题 Is is possible to set the MIME type for an iFrame dyanamically with JavaScript? Same question for DIV? 回答1: No. The MIME type is determined by what you load into it. For a frame that will be whatever the src specifies. Divs don't load external content so don't have MIME types. 回答2: I may have the answer you need. Although our purposes may be different. I spent days trying to specify MIME type for iframe because I use iframe to include text data into my .htm program. If the text data extension

How to obtain just a single form field from an HttpResponse in Java and write it to a file?

问题 I am calling a client's download service which sends back MIME data and attempting to save a zip file. The service does not simply return the file by itself but several other MIME fields as well. So when I open the inputstream using entity.getContent() I end up writing all of this data to my zip file whereas I only wish to write one part "Payload". I have searched and do not see anyway to obtain just the one individual part from the content. Code is below: HttpResponse response = services
