java - 收到 400 - 错误请求 Java 客户端

Question

我正在尝试使用小型 Java 程序执行请求，但收到 400 - 错误请求作为响应:

URI uri = new URIBuilder().setScheme("https")
                .setHost("somehost.com")
                .setPath("/API/v1/export").build();
        HttpPost post = new HttpPost(uri);
        post.setHeader("X-API-ID", "myId");
        post.setHeader("Accept", "application/json");
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        params.add(new BasicNameValuePair("format", "csv"));
        params.add(new BasicNameValuePair("userId", "userId"));
        post.setEntity(new UrlEncodedFormEntity(params));
        JsonNode responseJson = sendResponseEngineRequest(post);

此responseJson返回以下值:

{"meta":{"httpStatus":"400 - Bad Request","error":{"errorMessage":"Invalid Content-Type. expected=application/json found=application/x-www-form-urlencoded","errorCode":"RP_0.1"}}}

提前致谢。

Answer 1

答案实际上就在您收到的错误中。

您指定您只接受 post.setHeader("Accept", "application/json"); 并且错误告诉您您请求的是 found=application/x-www-form-urlencoded

如果您可以控制请求数据的端点，请将其更改为 application/json。如果您不将 post.setHeader("Accept", "application/json"); 更改为 post.setHeader("Accept", "application/x-www-form-urlencoded ");
