Question

我正在尝试使用java发送HTTP POST请求。我能够发送一个简单的json消息但是当我尝试向json消息添加多个属性时，我得到了400个错误的请求响应。我试图使用Gson to_json来正确显示它。有没有人知道我哪里错了？

public boolean Record(String message, LevelType levelType)
{
    try
    {

        URL url;
        url = new URL(String.format("https://intake.opbeat.com/api/v1/organizations/%s/apps/%s/errors/", this.OrganizationId, this.AppId));
        HttpURLConnection conn = (HttpURLConnection)url.openConnection();
        conn.setRequestProperty  ("Authorization", "Bearer " + this.SecretToken);
        conn.setRequestProperty("Content-Type", "application/json");
        conn.setRequestProperty("Accept", "application/json");
        conn.setRequestMethod("POST");
        conn.setDoOutput(true);

        //write parameters
        OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
        JsonObject test = new JsonObject();
        test.addProperty("Application ", ApplicationName);
        test.addProperty("Environment ", environment.name());
        test.addProperty("error ", message);
       String testAsJson = new Gson().toJson(test);
        writer.write(testAsJson);
        writer.flush();
        writer.close();

        // Get the response
        int responseCode = conn.getResponseCode();
        StringBuffer answer = new StringBuffer();
        BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line;
        while ((line = reader.readLine()) != null)
        {
            answer.append(line);
        }
        reader.close();
        //Output the response
        CustomLog.printlnVerbose(answer.toString());
    }
    catch (MalformedURLException ex)
    {
        CustomLog.println(ex);
    }
    catch (IOException ex)
    {
        CustomLog.println(ex);
    }
    //Send an http post to opbeat
    return true;
}

}

请将此文件保存在您的项目中：

码头-web.xml中

＆＃13;

<?xml version="1.0"?>
  <!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN"
  "http://jetty.mortbay.org/configure.dtd">

  <Configure id="WebAppContext" class="org.eclipse.jetty.webapp.WebAppContext">
          <Set name="maxFormContentSize" type="int">800000</Set>
  </Configure>

＆＃13;

＆＃13; 放置您的项目位置：.... / web / WEB-INF / jetty-web.xml

maxFormContentSize =设置你想要的人数。

Answer 2

我明白了。我需要做几件事。

更改＆＃34; writer.write（testAsJson）＆＃34; to＆＃34; writer.write（testAsJson.to_string）＆＃34;
添加第二个json对象时，而不是＆＃34; testAsJson.addProperty＆＃34;我需要使用＆＃34; testAsJson.add＆＃34;。

解决了我的错误并成功完成了POST请求。我非常感谢发布的答案！
