我正在尝试在我的 android 应用程序中创建对 Google Shortener Api 的 POST 请求。但它返回带有代码 400 的 Parse 错误消息。这是我的代码......我错过了什么吗?
final String GOOGL_URL = "https://www.googleapis.com/urlshortener/v1/url";
String tinyUrl = null;
final Gson gson = new Gson();
try
{
InputStream in;
HttpClient client = new DefaultHttpClient();
HttpResponse response;
JSONObject json = new JSONObject();
HttpPost post = new HttpPost(GOOGL_URL);
json.put("key", "my_key");
json.put("longUrl", longUrl);
post.setHeader("json", json.toString());
StringEntity se = new StringEntity(json.toString());
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,
"application/json"));
post.setEntity(se);
response = client.execute(post);
in = response.getEntity().getContent();
BufferedReader br = new BufferedReader(new InputStreamReader(in));
StringBuilder resultString = new StringBuilder();
String lineGet;
while ((lineGet = br.readLine()) != null) {
resultString.append(lineGet);
}
if (Common.DEBUG) {
Log.d(TAG, "Request string : " + json.toString());
Log.d(TAG, "Response string : " + resultString);
}
GooGlResult result = gson.fromJson(resultString.toString(),
GooGlResult.class);
return result.getId();
}
catch (Exception ex) {
System.out.println("UrlShortener "+ex);
return longUrl;
}
提前致谢..
