我没有在通过提取和PUT方法发送的Api端点中接收formdata。
我使用了POST方法,并且得出了我认为不建议更新的方法。 我对在localhost:3000上运行的laravel-API和在localhost:5000上运行的laravel-API做出了反应。
Route::put('updateSlide/{id}', 'SlidesController@updateSlide');
public function updateImage(Request $request, int $id)
{
$image = $this->slideRepo->findSlideById($id)->image;
if ($image) {
$result = Storage::disk('ucmp')->delete($image);
}
if ($request->hasFile('image') && $request->file('image') instanceof UploadedFile) {
return $this->slideRepo->saveCover($request->file('image'));
} // return response()->json($data);
// data is an array (note)
return null;
}
public function updateSlide(Request $request, int $id)
{
$imageUrl=$this->updateImage($request, $id);
return response()->json($this->slideRepo->updateSlide([
'caption' => $request['caption'],
'image' => $imageUrl,
'url' => $request['url']
],$id));
}
export const updateSlideApi = (token, _slide, id) => {
return {
url: `${BASE_URL}/api/updateSlide/${id}`,
opt: API.requestOptions("PUT",token,null,{ body: _slide }, true)
};
};
我的标题中没有内容类型。
我希望从laravel API函数获得json数据,但出现错误“只能抛出对象”

PHP不会解析PUT请求的正文。
使用POST
并向参数_method
添加值PUT
。

PHP放置给了我艰辛的时间,使用此功能将节省您解析其他方法的时间:
function parsePutRequest()
{
// Fetch content and determine boundary
$raw_data = file_get_contents('php://input');
$boundary = substr($raw_data, 0, strpos($raw_data, "\r\n"));
// Fetch each part
$parts = array_slice(explode($boundary, $raw_data), 1);
$data = array();
foreach ($parts as $part) {
// If this is the last part, break
if ($part == "--\r\n") break;
// Separate content from headers
$part = ltrim($part, "\r\n");
list($raw_headers, $body) = explode("\r\n\r\n", $part, 2);
// Parse the headers list
$raw_headers = explode("\r\n", $raw_headers);
$headers = array();
foreach ($raw_headers as $header) {
list($name, $value) = explode(':', $header);
$headers[strtolower($name)] = ltrim($value, ' ');
}
// Parse the Content-Disposition to get the field name, etc.
if (isset($headers['content-disposition'])) {
$filename = null;
preg_match(
'/^(.+); *name="([^"]+)"(; *filename="([^"]+)")?/',
$headers['content-disposition'],
$matches
);
list(, $type, $name) = $matches;
isset($matches[4]) and $filename = $matches[4];
// handle your fields here
switch ($name) {
// this is a file upload
case 'userfile':
file_put_contents($filename, $body);
break;
// default for all other files is to populate $data
default:
$data[$name] = substr($body, 0, strlen($body) - 2);
break;
}
}
}
return $data;
}
