Upload file using Guzzle 6 to API endpoint
提问by Brad
I am able to upload a file to an API endpoint using Postman.
我可以使用 Postman 将文件上传到 API 端点。
I am trying to translate that into uploading a file from a form, uploading it using Laravel and posting to the endpoint using Guzzle 6.
我试图将其转换为从表单上传文件，使用 Laravel 上传并使用 Guzzle 6 发布到端点。
Screenshot of how it looks in Postman (I purposely left out the POST URL)

Below is the text it generates when you click the "Generate Code" link in POSTMAN:
以下是当您单击 POSTMAN 中的“生成代码”链接时生成的文本：

Below is controller function for saving the file and other info. The file uploads correctly, I am able to get the file info.
下面是用于保存文件和其他信息的控制器功能。文件上传正确，我能够获取文件信息。
I think the problem I am having is setting the multipart and headers array with the correct data.
我认为我遇到的问题是使用正确的数据设置 multipart 和 headers 数组。
public function fileUploadPost(Request $request)
{
$data_posted = $request->input();
$endpoint = "/file-submissions";
$response = array();
$file = $request->file('filename');
$name = time() . '_' . $file->getClientOriginalName();
$path = base_path() .'/public_html/documents/';
$resource = fopen($file,"r") or die("File upload Problems");
$file->move($path, $name);
// { "name": "test_upload.txt", "clientNumber": "102425", "type": "Writeoff" }
$fileinfo = array(
'name' => $name,
'clientNumber' => "102425",
'type' => 'Writeoff',
);
$client = new \GuzzleHttp\Client();
$res = $client->request('POST', $this->base_api . $endpoint, [
'auth' => [env('API_USERNAME'), env('API_PASSWORD')],
'multipart' => [
[
'name' => $name,
'FileContents' => fopen($path . $name, 'r'),
'contents' => fopen($path . $name, 'r'),
'FileInfo' => json_encode($fileinfo),
'headers' => [
'Content-Type' => 'text/plain',
'Content-Disposition' => 'form-data; name="FileContents"; filename="'. $name .'"',
],
// 'contents' => $resource,
]
],
]);
if($res->getStatusCode() != 200) exit("Something happened, could not retrieve data");
$response = json_decode($res->getBody());
var_dump($response);
exit();
}

回答by revo
The way you are POSTing data is wrong, hence received data is malformed.
您发布数据的方式是错误的，因此接收到的数据格式错误。
狂饮文档：
The value of
multipartis an array of associative arrays, each containing the following key value pairs:
name: (string, required) the form field name
contents:(StreamInterface/resource/string, required) The data to use in the form element.
headers: (array) Optional associative array of custom headers to use with the form element.
filename: (string) Optional string to send as the filename in the part.
的值
multipart是一个关联数组的数组，每个数组包含以下键值对：
name: (string, required) 表单字段名
contents:(StreamInterface/resource/string, required) 要在表单元素中使用的数据。
headers：（数组）与表单元素一起使用的自定义标题的可选关联数组。
filename: (string) 作为文件名发送的可选字符串。
Using keys out of above list and setting unnecessary headers without separating each field into one array will result in making a bad request.
使用上面列表之外的键并设置不必要的标头而不将每个字段分成一个数组将导致发出错误的请求。
$res = $client->request('POST', $this->base_api . $endpoint, [
'auth' => [ env('API_USERNAME'), env('API_PASSWORD') ],
'multipart' => [
[
'name' => 'FileContents',
'contents' => file_get_contents($path . $name),
'filename' => $name
],
[
'name' => 'FileInfo',
'contents' => json_encode($fileinfo)
]
],
]);

$body = fopen('/path/to/file', 'r');
$r = $client->request('POST', 'http://httpbin.org/post', ['body' => $body]);
