使用vue插件axios传数据的Content-Type及格式问题详解

this.$axios({
	method: 'get',
	url: this.$store.state.api1 
		+ '&username=' + 'xxx' 
		+ '&password=' + 'xxx'
})

this.$axios({
	method: 'get',
	url: this.$store.state.api1,
	params: {
		username: 'xxx',
	  	password: 'xxx'
	}
})

this.$axios({
	url: this.$store.state.api1,
	method: 'post',
	data: {
		username: 'xxx',
	  	password: 'xxx'
	}
})

this.$axios({
	method: 'post',
	url: this.$store.state.api1,
	data: 'username=' + 'xxx'
		+ '&password=' + 'xxx'
	})

this.$axios({
method: 'post',
url: this.$store.state.api1,
data: qs.stringify({
	username: 'xxx',
	password: 'xxx'
})

// 获取文件
let input = document.querySelector('.input_file')
let curFiles = input.files

// 将文件放入formData中
let formData = new FormData()
for(let file of curFiles){
	formData.append('files', file)
}

// 将需要传递的参数放入formData中
formData.append('username', 'xxx')
formData.append('password', 'xxx')

// 调接口
this.$axios({
	url: this.$store.state.api1,
	method: 'post',
	data: formData
})
