chrome浏览器插件的background.js环境权限很高，可以跨域访问接口。自己封装一个Chrome插件，安装在扩展程序中，解决跨越问题。
使用方法
在自己的项目中id为cross-request-sign的标签。在页面加载之后可以访问window.crossRequest()就能跨越访问
- GET
crossRequest({
url: 'http://caibaojian.com/ajax-jsonp.html',
method: 'GET',
success: function(res, header){
}})- POST
crossRequest({
url: 'http://127.0.0.1:3000/api',
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
data: {
a: 1,
b: 2,
c: {
t: 1
}
},
success: function (res) {
console.log(arguments)
}
})- FILE upload
crossRequest({
url: 'http://127.0.0.1:8081/upload',
method: 'POST',
data: {
name: 'hello',
id: '19'
},
files: {
file: 'fileId' //File Upload-Input dom id
},
success: function (res) {
alert(res)
}
})文件结构
