获取no-cors意外的输入结束

Question

Using react and webpack.. why does the code below result in an error: Uncaught (in promise) SyntaxError: Unexpected end of input(…) ? Thanks

    fetch(feedURL, {"mode": "no-cors"})
    .then(response => response.json())
    .then(function(data){

        this.setState({
            data: data
        })

    }.bind(this));

Answer 1

To better understand your error, add a catch case to your fetch request.

Also, if you use arrow functions, you don't need to bind(this);

fetch(feedURL, {"mode": "no-cors"})
.then(response => response.json())
.then(data => {
    this.setState({
        data: data
    });
})
.catch(resp => {
    console.error(resp);
});
