如何使用vue.js发送文件?
以下代码对我不起作用:
<span title="Upload" class="badge badge-info">
<input type="file" id="file" name="file" @change="uploadData" class="archive" > <i id="iarchive" class="fa fa-upload"></i>
</span>
当我console.log(this.request.file)
时,我得到FILE [object File]
。
这是.js:
uploadData: function(e) {
var files = e.target.files[0];
this.request.action = 'upload';
this.request.file = files;
console.log("FILE "+this.request.file);
this.$http.post('data/getData.php', {
data: this.request,
headers: {
'Content-Type': 'multipart/form-data'
}
}
).then(function(response) {
console.log("RESPONSE: "+response.body);
}, function(response) {
alert("error");
});
return false;
}
但在PHP中,我无法获取该文件,响应为:{} No properties
。
PHP代码:
$request = json_decode(file_get_contents('php://input'));
$req = $request->data;
echo json_encode($req->file)

将ref属性添加到输入:
<input ref="file-input" .../>
在控制器中你应该写动作:
uploadFile: function () {
// try to log $refs object for deep understanding
let fileToUpload = this.$refs.fileInput.files[0];
let formData = new FormData();
formData.append('fileToUpload', fileToUpload);
this.$http.post ( 'data/getData.php', formData ).then(function () {
// success actions
});
}
在php端点中,您上传的文件将位于表单请求对象中。

使用FormData if let newVC = shouldAdd {
navigationController?.pushViewController(newVC, animated: true)
}
if var stack = navigationController?.viewControllers {
stack.remove(at: shoudlRemoveIndex)
navigationController?.viewControllers = stack
}
函数:
append()
