Postman是一款功能强大的网页调试与发送网页HTTP请求的Chrome插件。关于PostMan的下载和使用网上有很多相关的博客介绍&＃xff0c;本文主要介绍PostMan在进行模拟Http请求后可以根据需要的开发语言&＃xff0c;快速生成相应代码的过程。

示例请求以Microsoft Azure认知服务人脸识别Detect方法为例。

Body内容&＃xff1a;

{

"url": "http://www.gjstars.com/img/2017-4-17-67.jpg"

}

PostMan生成代码&＃xff1a;

使用PostMan自带Code功能生成JAva 代码&＃xff1a;

Java中使用OkHttpClient使用生成的代码测试。

Maven依赖&＃xff1a;

com.squareup.okhttp3

okhttp

3.10.0

Java 测试&＃xff1a;

Java Code&＃xff1a;

import okhttp3.*;

import java.io.IOException;

public class PostManDemo {

public static void main(String[] args) throws IOException {

OkHttpClient client &＃61; new OkHttpClient();

MediaType mediaType &＃61; MediaType.parse("application/json");

RequestBody body &＃61; RequestBody.create(mediaType, "{\r\n \"url\": \"http://www.gjstars.com/img/2017-4-17-67.jpg\"\r\n}");

Request request &＃61; new Request.Builder()

.url("https://api.cognitive.azure.cn/face/v1.0/detect?returnFaceId&＃61;true&returnFaceLandmarks&＃61;false&returnFaceAttributes&＃61;age")

.post(body)

.addHeader("Content-Type", "application/json")

.addHeader("Ocp-Apim-Subscription-Key", "73db498eb79943768d2a012a39b03e5f")

.addHeader("Cache-Control", "no-cache")

.addHeader("Postman-Token", "715400ac-fb98-b4ae-9c55-c7cf105e44be")

.build();

Response response &＃61; client.newCall(request).execute();

//打印输出结果

System.out.println(response.body().string());

}

}

结果&＃xff1a;

[{"faceId":"16760c9f-13f2-4318-89a1-f0884220b64c","faceRectangle":{"top":85,"left":68,"width":146,"height":146},"faceAttributes":{"age":25.8}}]
