python notes 8 : module de requêtes

PHP中文网original: 2017-07-09 18:13:091561parcourir

Présentation :

requests est une bibliothèque client http pour Python, similaire à urlib et urlib2. Le module de requêtes est développé sur la base du module urlib et l'implémentation du code est plus simple.

Installation des modules :

demandes d'installation pip, importez simplement les requêtes directement lorsque vous utilisez le module de requêtes.

Requêtes faciles à utiliser :

L'interface du protocole http, la méthode de requête est divisée en get et post, ces deux-là sont les plus couramment utilisés. Les formes de paramètres de demande couramment utilisées incluent la valeur-clé, le json, le téléchargement de fichiers, l'ajout d'interface de cookies, les en-têtes et d'autres opérations.

obtenir les paramètres d'épissage requête-url :

<span style="color: #0000ff">import</span><span style="color: #000000"> requests
url </span>= <span style="color: #800000">'</span><span style="color: #800000">http://127.0.0.1:5000/gettest?username=abc</span><span style="color: #800000">'</span>
<span style="color: #008000">#</span><span style="color: #008000">返回结果类型是字符串：{"msg": "pass"}</span>
res =<span style="color: #000000"> requests.<span style="color: #ff0000">get</span>(url).text</span><span style="color: #0000ff"><br></span>

Vous pouvez également utiliser .json(), et le type de résultat renvoyé est un dictionnaire (Remarque : le type de valeur de retour demandé par l'interface est lié au type de définition de retour de l'interface)

<span style="color: #008000">#</span><span style="color: #008000">返回结果类型是字典：{'msg': 'pass'}</span>
res_dic =<span style="color: #000000"> requests.<span style="color: #ff0000">get</span>(url).json()</span><span style="color: #0000ff"><br></span>

get request - le type de paramètre de requête est sous forme clé-valeur :

<span style="color: #0000ff">import</span><span style="color: #000000"> requests
url </span>= <span style="color: #800000">'</span><span style="color: #800000">http://127.0.0.1:5000/gettest</span><span style="color: #800000">'</span>
<span style="color: #008000">#</span><span style="color: #008000">请传参类型是 name=xxx&pwd=123456</span>
data = {<span style="color: #800000">"</span><span style="color: #800000">username</span><span style="color: #800000">"</span>: <span style="color: #800000">"</span><span style="color: #800000">abc</span><span style="color: #800000">"</span><span style="color: #000000">}
</span><span style="color: #008000">#</span><span style="color: #008000">返回结果类型是str：{"msg": "pass"}</span>
res = requests.<span style="color: #ff0000">get</span>(url, data).text

Vous pouvez également utiliser .json(), le type de résultat renvoyé est un dictionnaire (Remarque : le type de valeur de retour de la requête d'interface est lié au type de définition de retour de l'interface)

<span style="color: #008000">#</span><span style="color: #008000">返回结果类型是字典:{"msg": "pass"}</span>
res_dic =<span style="color: #000000"> requests.<span style="color: #ff0000">get</span>(url, data).json()</span><span style="color: #0000ff"><br></span>

L'interface appelée par requête get est implémentée comme suit :
