Android上的Facebook Graph API搜索

Question

我使用以下代碼來從Facebook Graph API檢索數據，並且可以正常工作。

GraphRequest.newGraphPathRequest(AccessToken.getCurrentAccessToken()
                        , "/me"
                        , new GraphRequest.Callback() {
                            @Override
                            public void onCompleted(GraphResponse response) {
                                showToast(response.toString());
                                ((TextView) findViewById(R.id.result_textview)).setText(response.toString());
                            }
                        }).executeAsync();

但是，當我使用以下可在Graph API Explorer中運行的搜索查詢時，它將不再起作用。

GraphRequest.newGraphPathRequest(AccessToken.getCurrentAccessToken()
                        , "/search?q=coffee&type=place"
                        , new GraphRequest.Callback() {
                            @Override
                            public void onCompleted(GraphResponse response) {
                                showToast(response.toString());
                                ((TextView) findViewById(R.id.result_textview)).setText(response.toString());
                            }
                        }).executeAsync();

錯誤json在下面。

Response:responseCode:400,
graphObject:null,
error:{  
   HttpStatus:400,
   errorCode:100,
   errorType:GraphMethodException,
   errorMessage:   Unsupported get request. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api
}
}

請閱讀文檔。 您做錯了方法。

new GraphRequest(
    AccessToken.getCurrentAccessToken(),
    "...?fields={fieldname_of_type_Location}",
    null,
    HttpMethod.GET,
    new GraphRequest.Callback() {
        public void onCompleted(GraphResponse response) {
            /* handle the result */
        }
    }
).executeAsync()

要么

GraphRequest request = GraphRequest.newGraphPathRequest(
  accessToken,
  "/search",
  new GraphRequest.Callback() {
    @Override
    public void onCompleted(GraphResponse response) {
      // Insert your code here
    }
});

Bundle parameters = new Bundle();
parameters.putString("type", "place");
parameters.putString("center", "53,27");
parameters.putString("distance", "30000");
request.setParameters(parameters);
request.executeAsync();

在現場，您可以使用國家/地區，經度，緯度，引用等。這是文檔

希望這對您有幫助。
