Retrieving POST information from forms on UIWebview (image, multipart/form-data)

Asked 1 years ago, Updated 1 years ago, 69 views

This is my first post. Thank you for your cooperation.

The following PHP files are placed on the server and loaded into the UIWebView.

<form action="native://test" method="post" enctype="multipart/form-data">
<input type="file" accept="image/jpeg,image/gif,image/png"name="files"name="photo">
<input type="text" name="name">
...
</form>

In Swift, use the shouldStartLoadWithRequest method to

 vardata:NSData?=request.HTTPBody

Then data is nil.

<input type="file" accept="image/jpeg,image/gif,image/png"name="files"name="photo">

data can be retrieved correctly instead of nil.

What I want to do is to save the image I sent from Form to SQLite. Another method is fine, please let me know.

If the amount of data sent is large, it appears that the data is set to HTTPBodyStream instead of HTTPBody.

This is a sample code from HTTPBodyStream to NSMutableData.

 iflet stream=request.HTTPBodyStream{
  stream.open()
  vardata —NSMutableData=NSMutableData()
  whilestream.hasBytesAvailable {
    var buffer = [UInt8] (count:512, repeatedValue:0)
    letlen:Int=stream.read(&buffer, maxLength:buffer.count)
    data.appendBytes (buffer, length:len)
  }
}
