使用java向自定义视觉服务预测API提交请求 [英] Submitting a request to the custom vision service prediction API using java

问题描述

我已经将代码作为c＃中的示例示例，并尝试将其切换为java。但是，java应用程序正在给出  http响应代码为400.如果我运行c＃应用程序，则正确到达预测API，因此我知道
值正确。 

可以找到示例c＃代码这里  https://docs.microsoft.com/en-us/azure/cognitive-services/custom-vision-service/use-prediction-api

我提交的java代码在这里：

 HttpURLConnection connection =（HttpURLConnection）url.openConnection（）; 
 connection.setDoOutput（true）; 
 
 connection.setRequestMethod（" GET"）; 
 connection.setRequestProperty（" Prediction-Key"，predictionKey）; 
 connection.setRequestProperty（" Content-Type"，" application / octet-stream"）; 
 
 DataOutputStream outputStream = new DataOutputStream（connection.getOutputStream（））; 
 outputStream.write（data.getData（））; 

我不确定上述java请求有什么问题。感谢任何帮助。

您好，这个问题更适合认知服务论坛：  https://social.msdn.microsoft.com/Forums/en-US/home?forum = AzureCognitiveService

I have take the code that is given as a sample example that is in c# and attempted to switch it to java. However, the java application is giving  http response code of 400. If i run the c# application the prediction API is reached correctly so i know the values are correct. 

The sample c# code can be found here https://docs.microsoft.com/en-us/azure/cognitive-services/custom-vision-service/use-prediction-api

my code for the java submission is here:

                        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                        connection.setDoOutput(true);

                        connection.setRequestMethod("GET");
                        connection.setRequestProperty("Prediction-Key", predictionKey);
                        connection.setRequestProperty("Content-Type", "application/octet-stream");

                        DataOutputStream outputStream = new DataOutputStream(connection.getOutputStream());
                        outputStream.write(data.getData());

I am not sure what is wrong with the above java request. Any help is appreciated, thanks.
