now the interface side gives an interface for uploading pictures and says that it wants to be in multipart/form-data format. Now there is a problem when transmitting data. The code is as follows
<f7-input type="file" id="z_img" placeholder="Name"/>
<span @click="shangchuan()"></span>
shangchuan:function(){
var self = this
var token_all = self.$global.token;
var qurl = self.$global.qurl;
var tupian = document.getElementById("z_img")
var img_src = tupian.files[0]
var data1 = new FormData();
data1.append("file",img_src)
self.$$.ajax({
url: qurl + "/api/common/uploadFile",
method: "post",
data: {data1},
processData : false,
contentType : false,
cache: false,
async:false,
headers: {
"Content-Type": "multipart/form-data; boundary=----WebKitFormBoundarykZiow0s1qkwq4AJH"
},
beforeSend: function (xhr) {
},
success: function (xhr111, status) {
const info = JSON.parse(xhr111);
console.log(status)
console.log(xhr111)
},
error: function (xhr111) {
},
complete: function (xhr) {
// $$(".gjjzdiv").hide();
}
});
}and then upload
in Google browser.
