我正在使用 angular 1.51 和 angular 1.6。我的 html 看起来像这样
<input type="file" name="file" />
和角度代码(基于这里的讨论):
let directive = {
..
link: (scope, element, attrs) => {
let inputElement = angular.element(element[0].querySelector('input'));
inputElement.bind('change', function () {
var formData = new FormData();
formData.append('file', inputElement[0].files[0]);
API.all('stores/csv').withHttpConfig({transformRequest: angular.identity}) .customPOST(formData,'' , undefined,
{ 'Content-Type': undefined }).then((response) => {console.log(response);
});
});
laravel 代码:
public function upload(Request $request)
{
$this->validate($request, [
'file' => 'required',
'type' => 'in:csv,xls,xlsx',
]);
$file = $request->file('file');
var_dump($file);
return response()->success(['file' => $file]);
}
问题是这里的 $file 在 laravel 转储中显示为一个空数组。文档在这方面非常糟糕。想法?
更新
使用邮递员可以正常工作。这是邮递员生成的卷曲:
邮递员卷曲:
curl -X POST \

这是由restangular生成的卷曲

更新2:
在比较两个卷曲之间的标题后,我注意到内容类型不同:
邮递员卷曲片段
-H 'Content-Type: application/x-www-form-urlencoded' \
restangular curl 片段
-H 'Content-Type: application/json'
这是令人震惊的,考虑到矩形人承诺通过使用上述语法,内容类型应该是application/x-www-form-urlencoded
:
Restangular.all('users') .withHttpConfig({transformRequest: angular.identity}) .customPOST(formData, undefined, undefined, { 'Content-Type': undefined }); 这基本上告诉请求使用 Content-Type: multipart/form-data 作为标头。
所以我写了这个:
API.all('stores/csv').withHttpConfig({transformRequest: angular.identity})
.customPOST(formData, undefined, undefined,
{ 'Content-Type': 'application/x-www-form-urlencoded' }).then((response) => {console.log(response);
这稍微改善了一些..现在比较两个卷发:
邮差
curl -X POST \
http://127.0.0.1:8000/api/stores/csv \
-H 'Accept: application/x.toters.v1+json' \
-H 'Authorization: Bearer ***' \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-H 'Postman-Token: 4f9d2f3b-551b-aa47-4f65-98c7582f2919' \
-H 'content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' \
-F file=@/Users/Shared/Download/bac-383-store-update.csv
有角度的
curl 'http://127.0.0.1:8000/api/stores/csv'
-H 'Origin: http://localhost:3000'
-H 'Accept-Encoding: gzip, deflate, br'
-H 'Accept-Language: en-US,en;q=0.9'

-H 'Connection: keep-alive'
