等待多次axios访问完毕

Question

我有如下的脚本。

它启动多个API访问。

    var temp = [];
    for (let i = 0; i < `10;i++){
        var url = `http://www.myapi.com/api/?id=${i}`;
        axios.get(url).then(res =>{
            temp[i] = res['data'];
            //I want to do something if every API get the results.
            }).catch(res => {
            console.log("axios error");
        });
    }
    

现在我想等待每 10 个 api 访问完成。

这可能吗？我该怎么做？

您可以使用 Promise.all 来等待多个请求，

Promise.all([
    fetch('https://jsonplaceholder.typicode.com/posts'),
    fetch('https://jsonplaceholder.typicode.com/users')
]).then(function (responses) {
    // Get a JSON object from each of the responses
    return Promise.all(responses.map(function (response) {
        return response.json();
    }));
}).then(function (data) {
    // Log the data to the console
    // You would do something with both sets of data here
    console.log(data);
}).catch(function (error) {
    // if there's an error, log it
    console.log(error);
});
