Question

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();
 }

   }

我正在使用休息的1.7，groovy 1.8.8，所有可靠的依赖项都加载到我的系统库路径中。我也在使用jdk 1.7。这是某种环境问题，作为一个同事，使用相同的.jar文件运行相同的代码没问题...

Answer 1

您的get似乎已返回NullPointerException。

at com.jayway.restassured.RestAssured.get(RestAssured.java:776)

此方法内部出现问题。

您可能错过了instructions中提到的第三方依赖项。加载其他类似乎会弹出错误。

非maven用户

下载REST Assured并将其放入您的类路径中。您可能还需要下载第三方依赖项并将它们放在类路径中。
