从安卓发布到goo.gl

Question

继续获取以下内容：

V/RESPONSE(13605):  {
V/RESPONSE(13605):  "error": {
V/RESPONSE(13605):   "errors": [
V/RESPONSE(13605):    {
V/RESPONSE(13605):     "domain": "global",
V/RESPONSE(13605):     "reason": "parseError",
V/RESPONSE(13605):     "message": "This API does not support parsing form-encoded input."
V/RESPONSE(13605):    }
V/RESPONSE(13605):   ],
V/RESPONSE(13605):   "code": 400,
V/RESPONSE(13605):   "message": "This API does not support parsing form-encoded input."
V/RESPONSE(13605):  }
V/RESPONSE(13605): }

使用以下代码：

String apiKey = "blahblahblah";
String address="https://www.googleapis.com/urlshortener/v1/url";
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(address);
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("key", apiKey));
pairs.add(new BasicNameValuePair("longUrl", original));

try {
    post.setEntity(new UrlEncodedFormEntity(pairs));
} catch (UnsupportedEncodingException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

try {
    org.apache.http.HttpResponse response = client.execute(post);
    String responseBody = EntityUtils.toString(response.getEntity());
    Log.v("RESPONSE"," "+responseBody);
} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    tinyUrl="Protocol Error";
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    tinyUrl="IO Error";
}

我不确定如何格式化它。有什么想法吗？

我试着删除UrlEncodedFormEntity，但当然不会起作用。

Answer 1

您需要以json格式发送数据，而不是像您试图做的那样以表单编码的形式发送数据。

请看一下文档here。

将实体更改为StringEntity，如下所示：

post.setEntity(new StringEntity("{\"longUrl\": \"http://www.google.com/\"}"));

同时设置请求的内容类型：

post.setHeader("Content-Type", "application/json");

Answer 2

还可以考虑使用我制作的库，它提供了一个很好的接口，可以使用Goo.gl服务缩短您的urls。

它支持api密钥，使用起来非常简单：

GoogleShortenerPerformer shortener = new GoogleShortenerPerformer(new OkHttpClient());

String longUrl = "http://www.andreabaccega.com/";

GooglShortenerResult result = shortener.shortenUrl(
    new GooglShortenerRequestBuilder()
        .buildRequest(longUrl)
    );
if ( Status.SUCCESS.equals(result.getStatus()) ) {
    // all ok result.getShortenedUrl() contains the shortened url!
}
