使用Java为Hangouts聊天API设置传入webhook？

我在这里遵循了这个示例（），它向一个聊天室发送一条简单的消息，并按预期工作

from httplib2 import Http
from json import dumps

def main():
    url = 'https://chat.googleapis.com/v1/spaces/AAAAUfABqBU/messages?key=<WEBHOCK-KEY>'
    bot_message = {
        'text' : 'Hello from Python script!'}

    message_headers = { 'Content-Type': 'application/json; charset=UTF-8'}

    http_obj = Http()

    response = http_obj.request(
        uri=url,
        method='POST',
        headers=message_headers,
        body=dumps(bot_message),
    )

    print(response)

if __name__ == '__main__':
    main()

---

我假设我添加json对象的方式有问题。有人看到错误了吗？

类似于转储，但移动行

final HttpResponse response=client.execute（request）设置请求正文后解决问题

private void sendPost() throws IOException {

    String url = "https://chat.googleapis.com/v1/spaces/AAAAUfABqBU/messages?key=<WEBHOCK-KEY>";

    final HttpClient client = new DefaultHttpClient();
    final HttpPost request = new HttpPost(url);
    // FROM HERE

    request.addHeader("Content-Type", "application/json; charset=UTF-8");

    final StringEntity params = new StringEntity("{\"text\":\"Hello from Java!\"}", ContentType.APPLICATION_FORM_URLENCODED);
    request.setEntity(params);

    // TO HERE
    final HttpResponse response = client.execute(request);

    final BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

    StringBuffer result = new StringBuffer();
    String line;
    while ((line = rd.readLine()) != null) {
        result.append(line);
    }

    System.out.println(result.toString());
}

private void sendPost（）引发IOException{

最终HttpClient=新的DefaultHttpClient（）；
最终HttpPost请求=新HttpPost（url）；

addHeader（“内容类型”，“应用程序/json；字符集=UTF-8”）；
最终的StringEntity参数=新的StringEntity（“{\”text\“：\”来自Java的你好！\“}”，ContentType.APPLICATION\u FORM\u URLENCODED）；

//到这里
最终HttpResponse响应=client.execute（请求）；
final BufferedReader rd=新的BufferedReader（新的InputStreamReader（response.getEntity（）.getContent（））；
StringBuffer结果=新的StringBuffer（）；
弦线；
而（（line=rd.readLine（））！=null）{
结果。追加（行）；
}
System.out.println（result.toString（））；
}

顺序有时确实很重要：）
