Here's how to write to a writable file on disk using the StorageFile class. The common first step for each of the ways of writing to a file unless you're writing to the file immediately after creating it is to get the file with StorageFolder.
First, call ConvertStringToBinary to get a buffer of the bytes based on an arbitrary string that you want to write to your file. First, open the file by calling the StorageFile. It returns a stream of the file's content when the open operation completes. Next, get an output stream by calling the GetOutputStreamAt method from the stream. Put this in a using statement to manage the output stream's lifetime. Now add this code within the existing using statement to write to the output stream by creating a new DataWriter object and calling the DataWriter.
Lastly, add this code within the inner using statement to save the text to your file with StoreAsync and close the stream with FlushAsync. Here's how to read from a file on disk using the StorageFile class. The common first step for each of the ways of reading from a file is to get the file with StorageFolder. Then use a DataReader object to read first the length of the buffer and then its contents. I normally use curl to make test requests and there's a curl mini-reference at the end of this article.
As a convention in this document, whenever a server response is presented, it is preceded by the HTTP request that was made to generate the particular response with any relevant parameters and headers.
The request itself is not part of the response. Routes can use different converters in their definition,. And sometimes that data can be in one of multiple formats: Accessing the HTTP headers is done using the request. Responses are handled by Flask's Response class:.
Mimetype is just the content-type without the additional information e. If possible, return the the full content type information. The previous example can be further simplified by using a Flask convenience method for generating JSON responses:. Specifying the mime type is particularly useful when using a custom mime type e.
