如何使用放心來調用Web服務

Question

我是新手，請放心 ，我很難用它來運行基本程序。 我剛剛創建了一個Java項目並添加了所需的放心罐子。 下面是我的簡單代碼：

import com.jayway.restassured.RestAssured;
import com.jayway.restassured.RestAssured.*;
import com.jayway.restassured.matcher.RestAssuredMatchers.*;
import org.hamcrest.Matchers.*;

public class RestServiceTest 
{

    public static void main(String args[]) throws Exception
    {
//        RestAssured.baseURI="http://restcountries.eu/rest/v1/";

          String str=RestAssured.get("http://restcountries.eu/rest/v1/name/Norway").asString();
          System.out.println(str);


    }
}

我還添加了一個pom.xml文件來添加以下依賴項。

<dependency>
  <groupId>com.sun.jersey.jersey-test-framework</groupId>
  <artifactId>jersey-test-framework-core</artifactId>
  <version>1.9</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>com.sun.jersey.jersey-test-framework</groupId>
  <artifactId>jersey-test-framework-external</artifactId>
  <version>1.9</version>
</dependency>

當我運行上面的代碼時，我得到以下異常：

有人可以幫忙，我需要創建一個maven項目或只是java項目並添加pom.xml文件？

我已經將maven添加到環境變量中。

Answer 1

您需要創建一個maven項目並將依賴項添加到pom.xml文件並構建maven項目。

您需要添加的其他依賴項：

<dependency>
    <groupId>com.jayway.restassured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>2.5.0</version>
</dependency>
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5</version>
</dependency>

Answer 2

問題似乎是你缺少Groovy的HTTP-Builder。

如果您已經在使用Maven，請嘗試將這些行添加到Maven pom.xml中的“dependencies”部分：

http://mvnrepository.com/artifact/org.codehaus.groovy.modules.http-builder/http-builder/0.6

<dependency>
    <groupId>org.codehaus.groovy.modules.http-builder</groupId>
    <artifactId>http-builder</artifactId>
    <version>0.6</version>
</dependency>

否則，請下載.jar（相同鏈接）並將其添加到項目的類路徑中。

另請參閱HTTP-Builder Wiki：
