由 微笑、不失礼 提交于 2019-12-22 17:48:40
问题 I am trying to perform two, non-concurrent request, but would like to use data from my first request before performing a second request. How can I achieve getting the data from the first request then using that data for the second request? axios.get('/user/12345').then(response => this.arrayOne = response.data); axios.get('/user/12345/' + this.arrayOne.name + '/permissions').then(response => this.arrayTwo = response.data); 回答1: You can just nest the second axios call inside the first one.

问题 So i'm trying to get an image from a server and previewing it on the client, i can retrieve the image for now, but i don't know how to preview it on a web page asynchronously. axios.get(link,{responseType:'stream'}).then(img=>{ // What i have to do here ? }); Thank you. 回答1: First, you need to fetch your image with the response type arraybuffer .

问题 I'm having an issue with axios and twitter API. I made successful request using Postman (with Authorization header set - OAuth 1.0).

componentDidMount: Can't call setState (or forceUpdate) on an unmounted component

问题 I am fetching data in componentDidMount and updating the state and the famous warning is appearing: Warning: Can't call setState (or forceUpdate) on an unmounted component.

My code is as follow: componentDidMount() { let self = this; let apiBaseUrl = Config.serverUrl; axios.get( apiBaseUrl + '/dataToBeFetched/' ) .then( function
