How to build fetch URLadresse using twoo parameters inside?-CodePudding

I want to sent request to Google Books using fetch to find book either by author or by tittle of book.

I don't have the problem to find books by using only one parameter where value is title of book for example:

   getData(value) {
    console.log(value);
    fetch(`https://www.googleapis.com/books/v1/volumes?q=intitle:${value}&printType=books&${myKey}`)
    .then(response => response.json())
    .then(data => console.log(data))
}

But if I want to use as value either author or tittle of the boks url works wrong. Books are found anly by author:

getData(value) {
    console.log(value);
    fetch(`https://www.googleapis.com/books/v1/volumes?q=inauthor:${value}&?q=intitle:${value}&printType=books&${myKey}`)
    .then(response => response.json())
    .then(data => console.log(data))
}

How to built url to fing the bokks either by author or by tittle.

CodePudding user response：

Since you want either to search for the author or title, wouldn't be easier if you do a small condition before and use the respective URL?

getValue(value, type){
   switch(type){
      case "title":
        fetch(`https://www.googleapis.com/books/v1/volumes?q=intitle:${value}&printType=books&${myKey}`)
        .then(response => response.json())
        .then(data => console.log(data))
        break;
      case "author":
        fetch(`https://www.googleapis.com/books/v1/volumes?q=inauthor:${value}&printType=books&${myKey}`)
        .then(response => response.json())
        .then(data => console.log(data))
        break;
   }
}

type would be what you want to search (in this case "author" or "title").

You need to add | (OR) between conditions, here you go:

https://www.googleapis.com/books/v1/volumes?q=intitle:${value}|inauthor:${value}&printType=books&${myKey}`

My example query:

https://www.googleapis.com/books/v1/volumes?q=flowers intitle:david|inauthor:keyes
