I am trying to upload a file through the post request in flask restfulplus
I followed the example in this link
Here is my code
#ns.route('/upload/logo/')
#ns.doc('Upload Logo')
class UploadImage(Resource):
#ns.param('picture', 'image file path')
# #ns.route('/upload/')
def post(self):
parse = reqparse.RequestParser()
parse.add_argument('picture', type=FileStorage, location='files', required=True)
argsd = parse.parse_args()
print(argsd)
imgFile = argsd['picture']
print(imgFile)
imgFile.save("your_file_name.jpg")
return {'successfully' : 'loaded'}
For some reason the file is not getting uploaded. Can someone help me to solve this problem.

I am trying to setup a POST request method using the "Add Item" operation within a REST API for my portal so that the PNG images can be add and later updated. Currently my script uploads the item to the portal but when i try to download the file or share it then it opens a page saying "Item does not have a file . Error 500" I assume its something to do with how i am building the POST request. How should i send the file over the POST request so that i can later download and update the file . Here is my current code:
def add_item(username,files,type,title):
"""
Add an item to the portal
Input:
- file: path of the the file to be uploaded
- username: username of user uploads the item
Return:
- Flag with a list of messages
"""
# set request header authorization type
header = {
'Authorization': f'Bearer {token}'
}
# build url
u_rl = f"{portal}/sharing/rest/content/users/{username}/addItem"
# search for id
req = requests.post(url=u_rl, headers=header,files=files,data={ "type":type,"title":title,"f": "json"})
response = json.loads(req.text)
if 'error' in response.keys():
error = response["error"]
raise Exception(
f"Error message: {error['message']}", f"More details: {','.join(error['details'])}")
return response["success"] if 'success' in response.keys() else False
if __name__ == "__main__":
user = input("input your USERNAME: ")
password = getpass.getpass("input your PASSWORD: ")
portal = "https://cvc.portal"
token = generate_token(user, password, portal=portal)
files = {'upload_file': open(r'C:\Users\test.png','rb')}
type='Image',
title='An image'
add_item(user,files,type,title
I'm trying to POST to a Sharepoint REST service an attached file with SoapUI Pro. I've tried the examples at: https://support.smartbear.com/readyapi/docs/requests/attachment/rest.html
But with no luck.
It should work with POST with byte-array as body. But how do I do that in SoapUI and Groovy?
In the tool Insomnia it works with "Binary File".
I add these headers:
Accept: application/json;odata=verbose
Content-Type: application/octet-stream
Media type = multipart/mixed and Post QueryString
But the file won't be uploaded to SharePoint.
PowerShell code that works:
$headers = #{
'X-RequestDigest' = 'xxxxxxxxxxxxxxxxxxxxxxx'
'Accept' = 'application/json;odata=verbose'
}
$document = [System.IO.File]::ReadAllBytes('C:\temp\myFile.docx')
Invoke-RestMethod -Method Post -UseDefaultCredentials -Uri "https://xxxx.xxx/add(url='myFile.docx',%20overwrite=true)" -Headers $headers -Body $document
I tried to go through this as well a while ago but I found it easier to use HTTP to do this.
You may try to see if it fits your requirements
My groovy script for attachment :
// upload source file before import
// get uploading request
def source_file = context.expand( '${#TestCase#source_file_path}' )
log.info "upload $source_file"
def aPIToolsTestSuite = context.expand( '${#Project#APIToolsTestSuite}' ) // the test suite that contains the test case with the HTTP request
tc_name = "import - upload resource files"
request = testRunner.testCase.testSuite.project.testSuites[aPIToolsTestSuite].testCases[tc_name].getTestStepByName("Request 1").testRequest
// clear request from any existing attachment
for (a in request.attachments)
{
request.removeAttachment(a)
}
// attach file to upload
def file = new File(source_file)
if (file == null)
{
log.error "bad file name : $source_file"
}
else
{
// attach file and set properties
try{
def attachment = request.attachFile (file, true)
attachment.contentType = "application/octet-stream"
attachment.setPart("upload file '$source_file'")
}
catch (Exception e){
log.error "file ${file.name} : exception $e"
}
}
// now upload file - launch the request
def jsonSlurper = new groovy.json.JsonSlurper()
def TC;
def async = false
TC = testRunner.testCase.testSuite.project.getTestSuiteByName(aPIToolsTestSuite).getTestCaseByName(tc_name)
result = TC.run (context.getProperties(), async)
if (String.valueOf( result.status ) != "PASS")
{
msg = "unexpected failure during $tc_name when uploading $source_file"
testRunner.fail(msg)
log.error msg
}
else
{
// this part is for further processing
// file uploaded, go through the import and properties backup process
resource_to_import = TC.getPropertyValue("testResponse").split('\"')[1]
// file uploaded, go through the import and properties backup process
testRunner.testCase.setPropertyValue("resource_id", resource_to_import)
}
And the HTTP request contained in the test case APIToolsTestSuite/import - upload resource files
first step : get endpoint
def env = testRunner.testCase.testSuite.project.activeEnvironment
rest = env.getRestServiceAt(0)
config = rest.getEndpoint().config
endpoint = new XmlSlurper().parseText(config.toString())
testRunner.testCase.setPropertyValue("endpoint", endpoint.toString())
second step, HTTP request:
POST
with Request tab parameters :
name : metadata
value : {"storageType":"FILESYSTEM","itemName":"my_source_file"}
type : QUERY
media type : multipart/form-data
Post QueryString
Headers : application/json
Good luck :)
I'm using the flask-user extension (https://flask-user.readthedocs.io/) along with the mongoengine adapter and flask-wtf to create an HTML form that'll accept several files (images, mp4). The goal is to directly store those files in MongoDB using GridFS but I can't get it to work without storing the image locally on the flask server first...
Here's my non-working code:
#bp.route('/video1', methods=['GET', 'POST'])
#login_required
def video1():
video1Form = Video1Form()
if request.method == 'POST' and video1Form.validate_on_submit():
newVideo1 = Video1(
slogan = video1Form.slogan.data,
objectif = video1Form.objectif.data,
stat1 = video1Form.stat1.data,
stat2 = video1Form.stat2.data
)
name = secure_filename(str(current_user.id) + "__" + "logo.png")
fh = open(video1Form.logo.data, 'rb')
newVideo1.logo.put(fh, filename=name, content_type = "image/jpeg")
newVideo1.save()
return redirect(url_for('video.download'))
if video1Form.errors:
flash(video1Form.errors, 'alert-danger')
return render_template('video/video1.html', video1Form=video1Form)
`
I get the following error on:
[...]File "/home/lucaspierru/Documents/IKADA/sos_sponsors/app/video/routes.py", line 35, in video1
fh = open(video1Form.logo.data, 'rb')
FileNotFoundError: [Errno 2] No such file or directory: 'name_of_the_uploaded_file.ext'
Is it possible to point directly to the file's content and not just get the filename without saving it to the server first ?
I found my mistake:
I forgot to add the enctype="multipart/form-data" attribute to my HTML <form> tag and apparently it is needed to properly upload files, otherwise they'll be considered as text data.
I am attempting to access the betfair API using Matlab and the urlread2 function available here.
EDIT: I have posted this problem on Freelancer if anyone can help with it: tinyurl.../pa7sblb
The documentation for the betfair API I am following is this getting started guide. I have successfully logged in and kept the session open using these codes: (I am getting a success response)
%% Login and get Token
url = 'https://identitysso.betfair.com/api/login';
params = {'username' '******' 'password' '******'};
header1 = http_createHeader('X-Application','*****');
header2 = http_createHeader('Accept','application/json');
header = [header1, header2];
[paramString] = http_paramsToString(params)
[login,extras] = urlread2(url,'POST',paramString,header)
login = loadjson(login)
token = login.token
%% Keep Alive
disp('Keep Session Alive')
url_alive = 'https://identitysso.betfair.com/api/keepAlive';
header1 = http_createHeader('X-Application','******');
header2 = http_createHeader('Accept','application/json');
header3 = http_createHeader('X-Authentication',token');
header_alive = [header1, header2, header3];
[keep_alive,extras] = urlread2(url_alive,'POST',[],header_alive);
keep_alive = loadjson(keep_alive);
keep_alive_status = keep_alive.status
My trouble starts when I am attempting to do the next step and load all available markets. I am trying to replicate this example code which is designed for Python
import requests
import json
endpoint = "https://api.betfair.com/exchange/betting/rest/v1.0/"
header = { 'X-Application' : 'APP_KEY_HERE', 'X-Authentication' : 'SESSION_TOKEN_HERE' ,'content-type' : 'application/json' }
json_req='{"filter":{ }}'
url = endpoint + "listEventTypes/"
response = requests.post(url, data=json_req, headers=header)
The code I am using for Matlab is below.
%% Get Markets
url = 'https://api.betfair.com/exchange/betting/rest/v1.0/listEventTypes/';
header_application = http_createHeader('X-Application','******');
header_authentication = http_createHeader('X-Authentication',token');
header_content = http_createHeader('content_type','application/json');
header_list = [header_application, header_authentication, header_content];
json_body = savejson('','filter: {}');
[list,extras] = urlread2(url_list,'POST',json_body,header_list)
I am having trouble with a http response code 415. I believe that the server cannot understand my parameter since the headings I have used with success previously.
Any help or advice would be greatly appreciated!
This is the error:
Response stream is undefined
below is a Java Error dump (truncated):
Error using urlread2 (line 217)
Java exception occurred:
java.io.IOException: Server returned HTTP response code: 415 for URL....
I looked at your problem and it seems to be caused by two things:
1) The content type should be expressed as 'content-type' and not 'content_type'
2) The savejson-function doesn't create an adequate json-string. If you use the json-request from the Python-script it works.
This code work for me:
%% Get Markets
url = 'https://api.betfair.com/exchange/betting/rest/v1.0/listEventTypes/';
header_application = http_createHeader('X-Application','*********');
header_authentication = http_createHeader('X-Authentication',token');
header_content = http_createHeader('content-type','application/json');
header_list = [header_application, header_authentication, header_content];
json_body = '{"filter":{ }}';
[list,extras] = urlread2(url,'POST',json_body,header_list)
I get the following error when trying to process uploaded images with imagick.
Fatal error: Uncaught exception 'ImagickException' with message 'unable to open image `9eK59iu.jpg': No such file or directory # error/blob.c/OpenBlob/2644' in D:\PATH\upload.php on line 77
The code looks like this:
<?php
$new_folder_name = "D:/PATH/content";
mkdir("$new_folder_name",0700);
$tmp_img = $_FILES["upload_file"]["tmp_name"];
$img = new Imagick($tmp_img);
$img->thumbnailImage(100 , 100 , TRUE);
$img->writeImage($new_folder_name);
?>
Without imagick the image upload works just fine.
Only imagick won't open the image given to $_FILES
I also tried to open the image with imagick, after move_uploaded_file, like this:
<?php
$extension = pathinfo($upload_file_name, PATHINFO_EXTENSION);
$new_upload_file_name = rand(00000, 99999).".".$extension;
$new_folder_name = "D:/PATH/content".time();
mkdir("$new_folder_name",0700);
$path_to_file = $new_folder_name."/".$new_upload_file_name;
move_uploaded_file($_FILES["upload_file"]["tmp_name"],$path_to_file);
$img = new Imagick($path_to_file);
$img->thumbnailImage(100 , 100 , TRUE);
$img->writeImage($new_folder_name);
?>
neither works.. :-(
Any suggestion?
Read the file upload docs. The server-side temporary filename assigned by PHP to store the uploaded file in ['tmp_name'] in the $_FILES array. You're trying to use the client-side user-provided ['name'], which DOES NOT exist anywhere on your server.
$tmp_img = $_FILES["upload_file"]["tmp_name"];
^^^^
You are also simply assuming that the upload has succeed. That is NOT a good thing. Never EVER assume success with dealing with remote resources (web apis, file uploads, database operations, etc...). ALWAYS check for errors:
if ($_FILES['upload_file']['error'] !== UPLOAD_ERR_OK) {
die("Upload failed with error code " . $_FILES['upload_file']['error']);
}
