let text = this.data.text;

let img_item = this.data.arrs;//图片地址数组

console.log(img_item)

var formData = new FormData();

console.log(typeof(form))

for(let a= 0 ;a<img_item.length;a++){

console.log(a)

formData.append("images[]", img_item[a])

}

formData.append("content", text)

console.log(formData.getAll("images[]"))

wx.request({

url: urls,//上传服务器的接口

method: "POST",

header: {

"Content-Type": "multipart/form-data",

"DeviceId": 310995000000000,

"access-token": token,

},

data: formData,

dataType: "json",

fail: function (res) {

console.log("网络异常")

},

success: function (res) {

console.log(res.data)

}

})

是不是content-type 需要改成什么样子的才能传成功？
