[SOLVED] Php posting file to ServiceStack API

Issue

I need help posting a file (doc, Docx, or pdf) to a ServiceStack API using PHP.

php cURL setup:

$curl = curl_init();
$cfile = new CURLFile('C:\\test.doc');
$params = array('Data' => $cfile);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($curl, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_POSTFIELDS,$params);

API setup:

 public object Any([FromBody]ExampleRequest exampleRequest){
...
}

public class ExampleRequest : IReturn<ExampleResponse>
    {
        public object Data { get; set; }
    }

With a property called Data of type object inside ExampleRequest

I'm not sure why Data will always be null. Any help would be appreciated

Solution

[FromBody] is not a ServiceStack Attribute and has no effect in ServiceStack Services.

Your Typed Request DTO needs to simply match the schema of the ExampleRequest. All ServiceStack Services can be populated by QueryString, FormData, or via Request Body in any of the default registered Content-Types like JSON. You need to ensure your Request is sending the correct format that matches its Content-Type HTTP Request Header.

It's recommended that you never use object otherwise you need to account for the custom serialization behavior and security restrictions for deserializing object types.

By defining a Data property, you're telling ServiceStack to accept requests with a Data property like (e.g. JSON):

{"Data": ...}

If sending flat Key/Value pairs, consider using Dictionary<string,string> instead of object

Parsing the Raw Request Body yourself

Your Request DTO should specify the Type of the Schema, if you don't want to do that you can tell ServiceStack to skip deserializing the Request Body and have your Service parse the raw Request Body by having your Request DTO implement IRequiresRequestStream, e.g:

//Request DTO
public class ExampleRequest : IRequiresRequestStream
{
    Stream RequestStream { get; set; }
}

Implementation:

public object Any(ExampleRequest request)
{
    byte[] bytes = request.RequestStream.ReadFully();
    string text = bytes.FromUtf8Bytes(); //if text was sent
}
