尝试运行此代码时出现以下错误：
import com.jayway.restassured.response.Response;
import static com.jayway.restassured.RestAssured.*;
public class TestRestAssured {
public static void main (String args[]){
// Call the REST service
Response res = get("http://10.213.75.170:5000/bla"); // <--- Crashes on this line.
// Get the JSON payload
String json = res.asString();
}
}

我使用的是放心的1.7，常规的1.8.8，所有放心的依赖项都已加载到我的系统库路径中。我也在使用jdk 1.7。作为同事，这是某种环境问题，因为使用相同的.jar文件运行相同的代码没有问题...
最佳答案
那么您的get似乎返回了NullPointerException。
at com.jayway.restassured.RestAssured.get(RestAssured.java:776)
该方法内部出现问题。
您可能错过了instructions中提到的第三方依赖性。加载其他类时，似乎弹出错误。
非Maven用户
下载REST Assured，并将其放在您的类路径中。您可能还需要下载第三方依赖项，并将它们也放入您的类路径中。
