導入

webAPIの叩き方を各言語でまとめました。
後で見返す用です。

json リクエストのサンプルパラメータ

sample_endpoint = "http://localhost:8888/sample"
sample_parameter = {
    "title": "トマトスープ",
    "making_time": "15分",
    "serves": "5人",
    "ingredients": "玉ねぎ, トマト, スパイス, 水",
    "cost": "450"
}

Curl

curl --location --request POST 'http://localhost:8888/recipes' \
--header 'Content-Type: application/json' \
--data-raw '{
    "title": "トマトスープ",
    "making_time": "15分",
    "serves": "5人",
    "ingredients": "玉ねぎ, トマト, スパイス, 水",
    "cost": "450"
}'

Go

package main

import (
  "fmt"
  "strings"
  "net/http"
  "io/ioutil"
)

func main() {

  url := "http://localhost:8888/recipes"
  method := "POST"

  payload := strings.NewReader(`{
    "title": "トマトスープ",
    "making_time": "15分",
    "serves": "5人",
    "ingredients": "玉ねぎ, トマト, スパイス, 水",
    "cost": "450"
}`)

  client := &http.Client {
  }
  req, err := http.NewRequest(method, url, payload)

  if err != nil {
    fmt.Println(err)
    return
  }
  req.Header.Add("Content-Type", "application/json")

  res, err := client.Do(req)
  if err != nil {
    fmt.Println(err)
    return
  }
  defer res.Body.Close()

  body, err := ioutil.ReadAll(res.Body)
  if err != nil {
    fmt.Println(err)
    return
  }
  fmt.Println(string(body))
}

php

<?php
require_once 'HTTP/Request2.php';
$request = new HTTP_Request2();
$request->setUrl('http://localhost:8888/recipes');
$request->setMethod(HTTP_Request2::METHOD_POST);
$request->setConfig(array(
  'follow_redirects' => TRUE
));
$request->setHeader(array(
  'Content-Type' => 'application/json'
));
$request->setBody('{\n    "title": "トマトスープ",\n    "making_time": "15分",\n    "serves": "5人",\n    "ingredients": "玉ねぎ, トマト, スパイス, 水",\n    "cost": "450"\n}');
try {
  $response = $request->send();
  if ($response->getStatus() == 200) {
    echo $response->getBody();
  }
  else {
    echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' .
    $response->getReasonPhrase();
  }
}
catch(HTTP_Request2_Exception $e) {
  echo 'Error: ' . $e->getMessage();
}

python

import requests
import json

url = "http://localhost:8888/recipes"

payload = json.dumps({
  "title": "トマトスープ",
  "making_time": "15分",
  "serves": "5人",
  "ingredients": "玉ねぎ, トマト, スパイス, 水",
  "cost": "450"
})
headers = {
  'Content-Type': 'application/json'
}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text)

これから

getパラメータの記述方法なども追記していく
