大佬教程收集整理的这篇文章主要介绍了通过iOS应用程序中的node.js将图像上传到服务器，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
//test file h3 Pic Upload form(action='/pic_upload',method='post',enctype='multipart/form-data') | @R_489_9004@pic: input(type='file',name='@R_489_9004@pic') input(type='submit') //app.js var userlogin =require('./routes/userlogin'); app.post('/pic_upload',userlogin.picUpload); //userlogin.js //picUpload function exports.picUpload = function(req,res) { console.log(req.files); // showing undefined,when called from IOS app // pic upload script... });
我尝试从应用程序端发送图像作为数据或文件参数,但它不起作用.如何从app端发送文件参数,以便我可以轻松地将图像@L_675_1@到服务器？请建议一种解决问题的方法.
