我正在尝试创建一个谷歌眼镜应用程序，它使用 CamFind api 来识别来自相机的对象。我已经安装了 maven，但它不会组装“主 jar”，所以我将依赖项添加到 gradle 构建路径。我已经让它编译没有任何错误（假设有 8 个警告），但它不会在没有错误的情况下完成对 api 的调用。
以下是相关代码：
包 com.akqa.glass.recipie；
import android.util.Log;
import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.JsonNode;
import com.mashape.unirest.http.Unirest;
import com.mashape.unirest.http.exceptions.UnirestException;
import org.json.JSONException;
import org.json.JSONObject;
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStream;
import java.io.InputStreamReader;
// For if I'm using Unirest - don't it's not working...
//import org.apache.http.HttpResponse;
//import org.shaded.apache.http.HttpHeaders;
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
private static final String TAG = JSONParser.class.getSimpleName();
// constructor
public JSONParser() {
}
public JSONObject getCamFindJSON(String type, String input) {
Log.d("PARSER", "Inside Parser");
/*
* Request processing from API
*/
if(type == "request"){
try {
HttpResponse<JsonNode> response = Unirest.post("https://camfind.p.mashape.com/image_requests")
.header("X-Mashape-Key", "Fhn5jZi5ixmshwnJMy7CGyj5yDCnp15DTQZjsniuwpVHfYHvFJ")
.field("image_request[image]", new File(input))
.field("image_request[locale]", "en_US")
.asJson();
} catch (UnirestException e) {
e.printStackTrace();
}
}
/*
* Receive response from API
*/
else if(type == "response"){
// These code snippets use an open-source library. http://unirest.io/java
try {
HttpResponse<JsonNode> response = Unirest.get("https://camfind.p.mashape.com/image_responses/" + input)
.header("X-Mashape-Key", "Fhn5jZi5ixmshwnJMy7CGyj5yDCnp15DTQZjsniuwpVHfYHvFJ")
.asJson();
} catch (UnirestException e) {
e.printStackTrace();
}
}
/*
* Parse Response into readable JSON
*/
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "n");
Log.d("Raw Data", line);
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
e.printStackTrace();
} catch (Exception e) {
Log.e("JSON Parse", "Unknown Error");
e.printStackTrace();
}
// return JSON String
return jObj;
}
}
这是相关的 gradle 构建路径：
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/NOTICE'
exclude 'META-INF/LICENSE'
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile files('C:/Users/torti_000/Documents/Recip.ie/libs/unirest-java-1.3.26.jar')
compile 'org.apache.httpcomponents:httpclient:4.3.5'
// compile 'org.apache.httpcomponents:httpclient-android:4.3.3'
compile 'org.apache.httpcomponents:httpmime:4.3.5'
compile 'org.apache.httpcomponents:httpasyncclient:4.0.2'
}
最后，这是 logcat 输出（我很确定这是导致所有问题的第一行）：
