java - 在 Java 类中的 HTTP 中发布 JSON 对象

Question

这是我将 JSON 发布为 json.toString() 时遇到的错误我被这个问题困扰了。需要帮助尽早克服这个问题

Error code -415
Unsupported Media Type.

代码是

String url = "http://0.0.0.0:0000/XXXX/XXXX?wsdl";
        HttpClient client=new DefaultHttpClient();
        HttpPost post = new HttpPost(url);
        post.setHeader("Accept", "application/json");
        post.setHeader("headerValue", "HeaderInformation");

        //setting json object to post request.
        JSONObject jsonObject=jsonValue();
        if(jsonObject!=null ){
            StringEntity entity = new StringEntity(jsonObject.toString(), "UTF8");
            entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
            post.setEntity(entity);

            //this is your response:
            HttpResponse response = client.execute(post);
            System.out.println("Response: " + response.getStatusLine());
            System.out.println(response.getStatusLine().toString());
        }else{
            System.out.println("jsonObject is Empty");

这意味着您接受帖子的服务不接受您提供的媒体类型。它可能用@Consumes(某些东西)进行注释。你需要找到它是什么。您在发布时必须明确指定媒体类型。

例如 JAX-RS 客户端 API:

Client client = ClientBuilder.newClient(new ClientConfig()
            .register(MyClientResponseFilter.class)
            .register(new AnotherClientFilter()));

String entity = client.target("http://example.com/rest")
            .register(FilterForExampleCom.class)
            .path("resource/helloworld")
            .queryParam("greeting", "Hi World!")
            .request(MediaType.TEXT_PLAIN_TYPE)
            .header("some-header", "true")
            .get(String.class);

根据您的情况，您需要更改:

.request(MediaType.TEXT_PLAIN_TYPE)
