python notes 8 : module de requêtes-Tutoriel Python-php.cn

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: #008000">#</span><span style="color: #008000">返回结果类型是字符串：{"msg": "pass"}</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>
