我是 Java 新手,我正在尝试创建一个库来从 Web 服务中获取巴西地址,但我无法读取响应。
在类的构造函数中,我有这个result
字符串,我想将响应附加到这个字符串中,一旦这个变量填充了响应,我就会知道该怎么做。
问题是:由于某种原因,我猜该BufferedReader
对象不工作,所以没有响应被读取:/
这是代码:
package cepfacil;
import java.net.*;
import java.io.*;
import java.io.IOException;
public class CepFacil {
final String baseUrl = "http://www.cepfacil.com.br/service/?filiacao=%s&cep=%s&formato=%s";
private String zipCode, apiKey, state, addressType, city, neighborhood, street, status = "";
public CepFacil(String zipCode, String apiKey) throws IOException {
String line = "";
try {
URL apiUrl = new URL("http://www.cepfacil.com.br/service/?filiacao=" + apiKey + "&cep=" +
CepFacil.parseZipCode(zipCode) + "&formato=texto");
String result = "";
BufferedReader in = new BufferedReader(new InputStreamReader(apiUrl.openStream()));
while ((line = in.readLine()) != null) {
result += line;
}
in.close();
System.out.println(line);
} catch (MalformedURLException e) {
e.printStackTrace();
}
this.zipCode = zipCode;
this.apiKey = apiKey;
this.state = state;
this.addressType = addressType;
this.city = city;
this.neighborhood = neighborhood;
this.street = street;
}
}
所以这是代码应该如何工作的,你构建一个像这样的对象:
String zipCode = "53416-540";
String token = "0E2ACA03-FC7F-4E87-9046-A8C46637BA9D";
CepFacil address = new CepFacil(zipCode, token);
// so the apiUrl object string inside my class definition will look like this:
// http://www.cepfacil.com.br/service/?filiacao=0E2ACA03-FC7F-4E87-9046-A8C46637BA9D&cep=53416540&formato=texto
// which you can check, is a valid url with content in there
为简洁起见,我省略了此代码的某些部分,但构造函数中调用的所有方法都在我的代码中定义,并且没有发生编译或运行时错误。
我很感激你能给我的任何帮助,我很想听听最简单的解决方案:)
提前致谢!
更新:现在我可以解决问题(@Uldz 向我指出问题的巨大道具)它是开源的http://www.rodrigoalvesvieira.com/cepfacil/
