「さがす」の一覧取得、とりあえずjavascriptでいけたわ

const urlConfig = "https://platform-api.tver.jp/v2/api/platform_users/browser/create";;
const urlSearch = "https://platform-api.tver.jp/service/api/v1/callSearch";;
const method = "POST";
const objConfig = {"device_type":"pc"};
let headers = {
'Content-Type': 'application/x-www-form-urlencoded; charset=utf-8'
};
const body = Object.keys(objConfig).map((key)=>key+"="+encodeURIComponent(objConfig[key])).join("&");
fetch(urlConfig, {method, headers, body}).then((res)=>{return(res.json())})
.then((resp)=>{
let platform_uid = resp.result.platform_uid;
let platform_token = resp.result.platform_token;
console.log("platform_uid =" + platform_uid);
console.log("platform_token=" + platform_token);
const url = urlSearch + `?platform_uid=${platform_uid}&platform_token=${platform_token}&keyword=&require_data=later`;
headers = {"x-tver-platform-type":"web"};
console.log("request url=" + url);
fetch(url,{headers}).then((res)=>{return(res.json())})
.then((json)=>{
// 「さがす」の番組情報
console.log(json);
});
})
.catch(console.error);
