I have a problem with the right receive POST:
python3, uwsgi 0.9.7
in html/js on chrome 10:
var xhr = new XMLHttpRequest;
var formData = new FormData();
formData.append("filename", file.fileName);
xhr.open("post", "/upload/", true);
xhr.send(formData);
And the data is sent. Chrome adds the headers correctly.
It receives in uWSGI:
{'CONTENT_LENGTH': '153',
'CONTENT_TYPE': 'multipart/form-data;
boundary=----WebKitFormBoundaryryYWB0YiAo4Ct3BF',
'HTTP_ACCEPT': '*/*',
'HTTP_ACCEPT_CHARSET': 'ISO-8859-2,utf-8;q=0.7,*;q=0.3',

'wsgi.multiprocess': True,
'wsgi.multithread': False,
'wsgi.run_once': False,
'wsgi.url_scheme': b'http',
'wsgi.version': (1, 0)}
backend code:
pprint(self.environ)
try: length = int(self.environ.get('CONTENT_LENGTH', '0'))
except ValueError: length = 0
form = cgi.FieldStorage(
fp=environ['wsgi.input'],
environ=environ,
keep_blank_values=1,
)
print(form['filename'])
On reading wsgi.input hangs like CONTENT_LENGTH was not correct.
It seems that waiting for data, but nothing comes.
When throw an exception timeout, it parses the data correctly.
after adding to ini:
post-buffering=4096
