java - RESTful 服务调用

Question

我正在使用 Chrome 插件，并且可以成功让我的服务正常工作:

我现在正尝试将同样的事情放入我的 Java 调用中。不过，我在将 Raw 部分放入我的 Java 服务时遇到问题。有什么想法吗？

  httpPost = new HttpPost(URL);
  nvps = new ArrayList<NameValuePair>();
  nvps.add(new BasicNameValuePair("Authorization", "Bearer " + token));
  nvps.add(new BasicNameValuePair("Content-Type", "application/json"));

  //I know this part is incorrect, but I don't know what to do with it
  nvps.add(new BasicNameValuePair("{\"pCode\": \"\", \"rType\": \"Sales Case\", \"subject\": \"test3\", \"description\": \"test4\", \"lookupInfo\": \"test5\", \"aaNum\": \"\"}", ""));

  try
  {
    httpPost.setEntity(new UrlEncodedFormEntity(nvps, "UTF-8"));
  } catch (UnsupportedEncodingException e)
  {
    e.printStackTrace();
  }

  HttpResponse response;
  try {
    response = client.execute(httpPost);
    BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
    String builder = "";

    String line = in.readLine();
    System.out.println("line = " + line);
  } catch (ClientProtocolException e)
  {
    e.printStackTrace();
  } catch (IOException e)
  {
    e.printStackTrace();
  }
}

HttpClient

我不知道你用什么来进行http调用，但是为了简单和理智，使用apache的httpclient。

示例

    HttpPost post = new HttpPost(URL);

    post.setHeader("Content-type", "application/json");
    post.setHeader("Authorization", "Bearer " + token));
    post.setHeader("Cache-Control", "no-cache"));

    FileBody fileBody = new FileBody(file);
    StringBody pCode = new StringBody("SOME TYPE OF VALUE", ContentType.MULTIPART_FORM_DATA);
    StringBody rType = new StringBody("SOME TYPE OF VALUE", ContentType.MULTIPART_FORM_DATA);
    //
    MultipartEntityBuilder builder = MultipartEntityBuilder.create();
    builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
    builder.addPart("pCode", pCode);
    builder.addPart("rType", rType);
    HttpEntity entity = builder.build();
    try
    {
        httpPost.setEntity(new UrlEncodedFormEntity(nvps, "UTF-8"));
    }catch (UnsupportedEncodingException e)
    {
       e.printStackTrace();
    }

    HttpResponse response;
    try {
       response = client.execute(httpPost);
       BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
       String builder = "";

       String line = in.readLine();
       System.out.println("line = " + line);
    } catch (ClientProtocolException e)
    {
      e.printStackTrace();
    } catch (IOException e)
    {
    e.printStackTrace();
  }

}

此代码尚未经过测试。

更新

JSON 只是一个奇特的字符串(从 java 的角度来看)，所以只需添加以下内容:

builder.addPart("someName", new StringBody(json, ContentType.TEXT_PLAIN));

更新2

上面将 JSON 添加为 POST 变量，而不是正文。 Look AT This Post
