继续获取:

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): }

使用此代码:

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？

我尝试删除 UrlEncodedFormEntity，但这当然行不通。

您需要将数据作为 json 发送，而不是像您尝试的那样以编码形式发送。

查看文档 here .

像这样将实体更改为 StringEntity:

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");
