Я хочу вызвать REST API с помощью Unity-Script, но это происходит из-за ошибки 400 Bad Request.Это может быть из-за http-заголовка.Можешь помочь мнеSAP предлагает фрагмент кода в JAVA, который я хочу сначала показать вам:
DataOutputStream dataOut = null;
BufferedReader in =null;
try {
//API endpoint for API sandbox
String url = "https://sandbox.api.sap.com/mlfs/api/v2/image/scene-text-
recognition";
//Available API Endpoints
//https://mlfproduction-scene-text-
recognition.cfapps.eu10.hana.ondemand.com/api/v2/image
//https://mlfproduction-scene-text-
recognition.cfapps.us10.hana.ondemand.com/api/v2/image
URL urlObj = new URL(url);
HttpURLConnection connection = (HttpURLConnection)
urlObj.openConnection();
//setting request method
connection.setRequestMethod("POST");
//adding headers
connection.setRequestProperty("content-type","multipart/form-data;
boundary=---011000010111000001101001");
//API Key for API Sandbox
connection.setRequestProperty("APIKey","----api-Key---");
//Available Security Schemes for productive API Endpoints
//OAuth 2.0
connection.setDoInput(true);
//sending POST request
connection.setDoOutput(true);
dataOut = new DataOutputStream(connection.getOutputStream());
dataOut.writeBytes("-----011000010111000001101001\r\nContent-
Disposition: form-data; name=\"files\"; filename=\"<file_name>\"\r\nContent-Type: <file_type>\r\n\r\n<file_contents>\r\n-----011000010111000001101001--");
dataOut.flush();
int responseCode = connection.getResponseCode();
in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
//printing response
System.out.println(response.toString());
} catch (Exception e) {
//do something with exception
e.printStackTrace();
} finally {
try {
if(dataOut != null) {
dataOut.close();
}
if(in != null) {
in.close();
}
} catch (IOException e) {
//do something with exception
e.printStackTrace();
}
}
Мой UnityCode выглядит примерно так:
public void ExecutePost()
{
Debug.Log("execute started");
byte[] img =
File.ReadAllBytes(@"C:\Users\InnovationLab\Documents\ECENTA\ECENTA
FSE\Bild1.jpg");
string url = "https://sandbox.api.sap.com/mlfs/api/v2/image/scene-
text-recognition";
coroutine = Post(url, img);
StartCoroutine(coroutine);
}
public IEnumerator Post(string url,byte[] image)
{
WWWForm form = new WWWForm();
form.AddBinaryData("imageField", image, "HoloImg");
var headers = new Dictionary<string, string> {
{"content-type", "multipart/form-data; boundary=---011000010111000001101001" },
{"APIKey", "---here I implemented the key---" }
};
WWW www = new WWW(url, image, headers);
yield return www;
if (www.error != null && www.error != "")
{ // on error, show information and return
Debug.Log("Network Error occured: " + www.error);
yield break;
}
while (!www.isDone)
{
Debug.Log(www.text);
}
}
}
Поэтому мой вопрос заключается в том, как изменить единствокод, чтобы он работал?
