<h1>Paf'Py</h1>
|

<p>Et Paf.</p>
|
||||
<p>Et PAF !</p>
|
||||
|
||||
<p>Ce « pastebin-like » s’utilise en ligne de commande, soit avec <tt>curl</tt> :</p>
|
||||
<h2>Envoyer un ou plusieurs fichiers</h2>
|
||||
|
||||
<div class="highlight"><pre><span></span>curl {{ request.build_absolute_uri }} <span class="o">-F</span>hello.py<span class="o">=</span>@hello.py
|
||||
En utilisant des requêtes <tt>multipart/form-data</tt> il est possible
|
||||
d'envoyer un fichier :
|
||||
|
||||
<div class="highlight"><pre><span></span>curl {{ request.build_absolute_uri }} <span class="o">-F</span>manage.py<span class="o">=</span>@manage.py
|
||||
| URL | size | filename |
|
||||
|-------------------------|--------|-----------|
|
||||
| https://p.afpy.org/g3LE | 251 | manage.py |
|
||||
</pre></div>
|
||||
|
||||
<p>Mais le mieux est de l'utiliser avec une fonction <tt>bash</tt> :</p>
|
||||
ou plusieurs fichiers en même temps :
|
||||
|
||||
<div class="highlight"><pre><span></span>pafpy<span class="o">()</span>
|
||||
<div class="highlight"><pre><span></span>curl {{ request.build_absolute_uri }} <span class="o">-F</span>manage.py<span class="o">=</span>@manage.py <span class="o">-F</span>requirements.txt<span class="o">=</span>@requirements.txt
|

| URL | size | filename |
|

|-------------------------|--------|------------------|
|
||||
| https://p.afpy.org/g3LE | 251 | manage.py |
|
||||
| https://p.afpy.org/k4oT | 547 | requirements.txt |
|
||||
</pre></div>
|
||||
|
||||
C'est l'extension dans le nom du fichier qui permet de choisir la
|
||||
coloration syntaxique pour chaque fichier.
|
||||
|
||||
|
||||
<h2>Envoyer dans le corps d'une requête</h2>
|
||||
|
||||
Il est possible de coller un unique fichier via le corps d'une requête <tt>POST</tt> :
|
||||
|
||||
<div class="highlight"><pre>
|
||||
$ cal | curl -XPOST --data-binary @- {{ request.build_absolute_uri }}
|
||||
| URL | size | filename |
|
||||
|-------------------------|--------|----------|
|
||||
| https://p.afpy.org/mo8X | 184 | request |
|
||||
|
||||
</pre></div>
|
||||
|
||||
Dans ce cas, il est possible de choisir la coloration syntaxique via l'entête <tt>Content-Type</tt> :
|
||||
|
||||
<div class="highlight"><pre>
|
||||
$ cal | curl -XPOST -H <span class="s2">"Content-Type: text/plain"</span> --data-binary @- {{ request.build_absolute_uri }}
|
||||
| URL | size | filename |
|
||||
|-------------------------|--------|-------------|
|
||||
| https://p.afpy.org/dNuo | 184 | request.txt |

<h2>Fonction <tt>bash</tt></h2>
|
||||
|
||||
<p>Pour ceux qui ne souhaitent pas rédiger des requêtes <tt>curl</tt>
|
||||
toute la journée, voici une petite fonction <tt>bash</tt> :</p>
|
||||
|
||||
<div class="highlight"><pre><span></span>paf<span class="o">()</span>
|
||||
<span class="o">{</span>
|
||||
curl {{request.build_absolute_uri}} -F<span class="s2">"</span><span class="nv">$1</span><span class="s2">=@</span><span class="nv">$1</span><span class="s2">"</span>
|
||||
<span class="k">if</span> <span class="o">[[</span> <span class="nv">$#</span> <span class="o">==</span> <span class="m">0</span> <span class="o">]]</span>
|
||||
<span class="k">then</span>
|
||||
curl https://p.afpy.org/ --data-binary @- -H <span class="s2">"Content-Type: text/plain"</span>
|
||||
<span class="k">else</span>
|
||||
curl https://p.afpy.org/ <span class="s2">"</span><span class="si">${</span><span class="p">@/*/-F&=@&</span><span class="si">}</span><span class="s2">"</span>
|
||||
<span class="k">fi</span>
|
||||
<span class="o">}</span>
|
||||
</pre></div>
|
||||
|
||||
Demo :
|
||||
Cette fonction est capable d'envoyer un fichier :
|
||||
|
||||
<div class="highlight"><pre><span></span>$ pafpy manage.py
|
||||
https://p.afpy.org/g3LE
|
||||
<div class="highlight"><pre><span></span>$ paf manage.py
|
||||
| URL | size | filename |
|
||||
|-------------------------|--------|-----------|
|
||||
| https://p.afpy.org/g3LE | 251 | manage.py |
|
||||
</pre></div>
|
||||
|
||||
On peut le voir dans un navigateur (avec de la coloration syntaxique) :
|
||||
<a href="https://p.afpy.org/g3LE">https://p.afpy.org/g3LE</a>), ou on peut le télécharger "brut" :
|
||||
plusieurs fichiers :
|
||||
|
||||
<div class="highlight"><pre><span></span>$ paf *.py
|
||||
| URL | size | filename |

</pre></div>
|
||||
|

et même de lire sur <tt>stdin</tt> :
|

<div class="highlight"><pre><span></span>$ cal | paf
|

| URL | size | filename |
|
