本文介绍了laravel vuejs/axios PUT Request Formdata为空的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有几个应用程序，当我使用axios发送表单数据时，POST数据被成功发送到API。但是当我使用PUT请求时，它不能与formData一起使用。

Whenedit选项TRUE。我正在使用axios put调用方法addLeadsAPI过帐数据，但Formdata为空$request->all()。
axios put不是在编辑数据。通过表单数据。
推荐答案
我已将axioscall改为POST并设置值_method:put
addLeads() {
if (this.edit === false) {
// add new leads
this.errors = null;
const constraints = this.getConstraints();
const errors = validate(this.$data.form, constraints);
if (errors) {
this.errors = errors;
return;
}
// multiple file uploading
this.lead = document.getElementById("leadform");
const formData = new FormData(this.lead);
if (this.attachments.length > 0) {
for (var i = 0; i < this.attachments.length; i++) {
let attachment = this.attachments[i];
formData.append("attachments[]", attachment);
}
}
var config = {
headers: { "Content-Type": "multipart/form-data" },
onUploadProgress: function(progressEvent) {
this.percentCompleted = Math.round(
(progressEvent.loaded * 100) / progressEvent.total
);
this.$forceUpdate();
}.bind(this)
};
//end
this.$store.dispatch("lead");
formData.append("_method", "post");
addLeadsAPI(formData, "post", config).then(res => {
swal("Good job!", "You clicked the button!", "success");
this.clearForm();
this.fetchLeads();
//this.attachments = [];
});
} else {
this.errors = null;
const constraints = this.getConstraints();
const errors = validate(this.$data.form, constraints);
if (errors) {
this.errors = errors;
return;
}
console.log("i am in edit");
// multiple file uploading
this.lead = document.getElementById("leadform");
let formData = new FormData(this.lead);
if (this.attachments.length > 0) {
for (var i = 0; i < this.attachments.length; i++) {
let attachment = this.attachments[i];
formData.append("attachments[]", attachment);
