@ccc This link is for Microsoft OneDrive. My Dropbox space is limited.

The original link is a more permanent and reliable alias to this URL.

I believe this is a copy of the last XCode Template modified by @coltonboyd. I have only used it to run the simulator with the latest version of XCode. It throws some warnings, but works for testing.

@ihf This script appears to work with python 2 or 3. Try changing #!python3 to #python2. It shouldn't be using simplejson, since json is a core python module. I see now that the your error may be a problem with your requests package. LIne 42 which reads result = r.json coverts the result to json. Line 41 contains json.dumps(data), which converts the arguemnts to a string.

@enceladus Thanks for creating the gist.

@enceladus Please go ahead and make a gist. I hope contribute more in the future when I have more time. Thanks!

@ihf I think there may be multiple versions of Dropbox file picker. The one a modified referenced 'r', not 'response' as the object that receives the download file.

Here is my complete download function.

def download_file(path, dest_filename, progress=None):
    data = {'path':path}
    headers = {'Authorization': 'Bearer %s' % (TOKEN,),'Dropbox-API-Arg': json.dumps(data)}
    url = 'https://content.dropboxapi.com/2/files/download'
    r = requests.post(url, stream=True, headers=headers)
    dest_path = os.path.join(os.path.expanduser('~/Documents'), dest_filename)
    i = 1
    while os.path.exists(dest_path):
        base, ext = os.path.splitext(dest_filename)
        dest_path = os.path.join(os.path.expanduser('~/Documents'), base + '-' + str(i) + ext)
        i += 1
    size = r.headers.get('Content-Length', 0)
    bytes_written = 0
    canceled = False
    with open(dest_path, 'w') as f:
        for chunk in r.iter_content(1024*10):
            f.write(chunk)
            bytes_written += len(chunk)
            if size > 0 and callable(progress):
                p = float(bytes_written) / float(size)
                should_cancel = progress(p)
                if should_cancel:
                    canceled = True
                    break
    if canceled:
        os.remove(dest_path)

I fixed one bug.
I had to redefine is_dir or else folders were defined as files.

    @ui.in_background
    def load_folder(self):
        infos = list_folder(self.path)
        items = []
        if self.path != '/':
            items.append({'title': '..', 'image': 'ionicons-arrow-up-c-32', 'up': True})
        if not infos:
            import console
            console.alert('Error', 'Could not load folder. Please check if you entered the access token correctly.', 'OK', hide_cancel_button=True)
            self.status_label.hidden = True
            return
        for info in infos:
            path = info.get('path_display')
            name = os.path.split(path)[1]
            if name.startswith('.'):
                continue
            #is_dir = info.get('is_dir', False)
            is_dir  = True if info.get('.tag') == 'folder' else False
            item = {'title': name, 'image': 'ionicons-folder-32' if is_dir else 'ionicons-ios7-download-outline-32', 'accessory_type': 'disclosure_indicator' if is_dir else 'none', 'is_dir': is_dir, 'path': info['path_display']}
            items.append(item)
        def c(o1, o2):
            u_cmp = -1 * cmp(o1.get('up', False), o2.get('up', False))
            if u_cmp != 0:
                return u_cmp
            d_cmp = -1 * cmp(o1.get('is_dir', False), o2.get('is_dir', False))
            if d_cmp == 0:
                return cmp(o1.get('path', '').lower(), o2.get('path', '').lower())
            return d_cmp
        items.sort(cmp=c)
        self.tableview.data_source.items = items
        self.status_label.hidden = True
        self.name = self.path

Ok. Now I see how to include source.

import requests
import urllib
import os
import ui
import json

def list_folder(folder_path='/'):
    headers = {'Authorization': 'Bearer %s' % (TOKEN,),'Content-Type': 'application/json' }
    if folder_path == '/': folder_path = ''
    data = {'path':folder_path}
    r = requests.post('https://api.dropboxapi.com/2/files/list_folder', headers=headers, data=json.dumps(data))
    result = r.json()
    return result.get('entries', None)

def download_file(path, dest_filename, progress=None):
    data = {'path':path}
    headers = {'Authorization': 'Bearer %s' % (TOKEN,),'Dropbox-API-Arg': json.dumps(data)}
    url = 'https://content.dropboxapi.com/2/files/download'
    r = requests.post(url, stream=True, headers=headers)

You also need to replace 'path' with 'path_dislpay' in twice in def load_folder.

@ui.in_background
    def load_folder(self):
        infos = list_folder(self.path)
        items = []
        if self.path != '/':
            items.append({'title': '..', 'image': 'ionicons-arrow-up-c-32', 'up': True})
        if not infos:
            import console
            console.alert('Error', 'Could not load folder. Please check if you entered the access token correctly.', 'OK', hide_cancel_button=True)
            self.status_label.hidden = True
            return
        for info in infos:
            path = info.get('path_display')
            name = os.path.split(path)[1]
            if name.startswith('.'):
                continue
            is_dir = info.get('is_dir', False)
            item = {'title': name, 'image': 'ionicons-folder-32' if is_dir else 'ionicons-ios7-download-outline-32', 'accessory_type': 'disclosure_indicator' if is_dir else 'none', 'is_dir': is_dir, 'path': info['path_display']}

This is my first post. I will try to include source.

import json

def list_folder(folder_path='/'):
    headers = {'Authorization': 'Bearer %s' % (TOKEN,),'Content-Type': 'application/json' }
    if folder_path == '/': folder_path = ''
    data = {'path':folder_path}
    r = requests.post('https://api.dropboxapi.com/2/files/list_folder', headers=headers, data=json.dumps(data))
    result = r.json()
    return result.get('entries', None)

def download_file(path, dest_filename, progress=None):
    data = {'path':path}
    headers = {'Authorization': 'Bearer %s' % (TOKEN,),'Dropbox-API-Arg': json.dumps(data)}
    url = 'https://content.dropboxapi.com/2/files/download'
    r = requests.post(url, stream=True, headers=headers)

You also need to change 'path' to 'path_display' in two places in def load_folder.

I've been using the v2 dropbox for a year, but hadn't tried to update any pythonista code until today. I have only done a few minutes of testing.

        for info in infos:
            path = info.get('path_display')
            name = os.path.split(path)[1]
            if name.startswith('.'):
                continue
            is_dir = info.get('is_dir', False)
            item = {'title': name, 'image': 'ionicons-folder-32' if is_dir else 'ionicons-ios7-download-outline-32', 'accessory_type': 'disclosure_indicator' if is_dir else 'none', 'is_dir': is_dir, 'path': info['path_display']}
            items.append(item)
