几个月以来,我一直在放心工作。
从开源API获取数据时,发现通过Postman API进行GET调用时返回200,并且接收到有效/预期的数据。
编写以下代码(使用Rest-Assured的Java)从API获取相同的数据:
package com.type.GetFuelTypeFromAPI;
import static io.restassured.RestAssured.given;
import java.net.MalformedURLException;
import java.net.URL;
import org.testng.annotations.Test;
import io.restassured.response.Response;
public class SampleGetAPI {
@Test
public void getDetails() throws MalformedURLException {
Response response=
given()
.queryParam("cmd", "getTrims")
.queryParam("make", "Abarth")
.queryParam("year", "1955")
.queryParam("model", "207")
.when()
.get(new URL("https://carqueryapi.com/api/0.3/"));
String responseBody = response.body().asString();
System.out.println(responseBody);
}
}
代码输出为:

有人可以指导我如何克服这个问题吗?

经过大量搜索后,执行以下步骤:
使用Wireshark捕获邮递员和保证安全的API调用。

标题 User-Agent 的值不同。该API阻止了对 Apache-HttpClient 的请求,但允许了 PostmanRuntime / 7.6.0 。
更新了代码,使标头 User-Agent 的值为 PostmanRuntime / 7.6.0 ,并且可以正常工作。
下面是工作代码:
package com.type.GetFuelTypeFromAPI;
import static io.restassured.RestAssured.given;
import java.net.MalformedURLException;
import java.net.URL;
import org.testng.annotations.Test;
import io.restassured.response.Response;
public class SampleGetAPI {
@Test
public void getDetails() throws MalformedURLException {
Response response=
given()
.header("User-Agent", "PostmanRuntime/7.6.0")
.queryParam("cmd", "getTrims")
.queryParam("make", "Abarth")
.queryParam("year", "1955")
.queryParam("model", "207")
.when()
.get(new URL("https://carqueryapi.com/api/0.3/"));
String responseBody = response.body().asString();
System.out.println(responseBody);
}
}
