1858	uWSGI params Content length issue when uploading file	heavey.sam@…		"Hello,

Working on 1.17 and using Nginx Upload Module I have come across a small bug. Perhaps only relevant to the 3rd party module but I have not had the time to check the source code. Apologies.

Have a look at the config below which '''does''' work. Basically, if the uwsgi params variable CONTENT_LENGTH (last line) is stored in the uwsgi params file and then ''included'', I run into problems. 

I have a flask app behind uWSGI and when I call ''request.form'' it hangs. This is after the 3rd party module strips the file from the body. However, it was not changing the content length. ''flask.request.form'' was waiting for further bytes to close off the request. As you can see I have declared it separately. 


	location /upload/ {

		auth_request     /upload_auth/;

		upload_pass @uploads;
		upload_store (redacted)
		upload_store_access all:rw;

		upload_set_form_field $upload_field_name.name ""$upload_file_name"";
		upload_set_form_field $upload_field_name.content_type ""$upload_content_type"";
		upload_set_form_field $upload_field_name.path ""$upload_tmp_path"";
		upload_pass_form_field ""^FileName$|^File$|^path$|^name$|^test$"";
	}

	location @uploads {
		uwsgi_pass (redacted)
		uwsgi_pass_request_body on;
		include /etc/nginx/uwsgi_params;
		uwsgi_param CONTENT_LENGTH $content_length;
        }
