JSON 和 JAVA 的 FOR 循环 [关闭]

Question

我有以下包含 JSON 的 POST API 代码。 JSON 中有一个 URL 提及为“https://nike.com” 我希望一次又一次地调用相同的 API，但要使用不同的 URL。我一直在通过调用这些 API 来截取提到的 URL 网页，所以我需要添加不同的 URL。 有没有办法一次添加两个或多个 URL，例如使用 for 循环或其他方法？

OkHttpClient client = new OkHttpClient();

MediaType mediaType = MediaType.parse("application/json");
RequestBody body = RequestBody.create(mediaType, "{\r\n  \"url\": \"https://www.nike.com\",\r\n  \"defer_time\": 5,\r\n  \"email\": true,\r\n  \"mac_res\": \"1024x768\",\r\n  \"win_res\": \"1366X768\",\r\n  \"smart_scroll\": true,\r\n  \"layout\": \"portrait\",\r\n  \"configs\": {\r\n    \"windows 10\": {\r\n      \"chrome\": [\r\n        \"76\",\r\n        \"75\",\r\n        \"74\"\r\n\r\n      ],\r\n      \"firefox\": [\r\n        \"67\",\r\n        \"66\"\r\n      ],\r\n      \"opera\": [\r\n        \"58\",\r\n        \"57\"\r\n      ],\r\n      \"ie\": [\r\n        \"11\"\r\n      ]\r\n    },\r\n    \"macos mojave\": {\r\n      \"chrome\": [\r\n        \"76\",\r\n        \"75\"\r\n      ],\r\n      \"firefox\": [\r\n        \"67\",\r\n        \"66\"\r\n      ],\r\n      \"opera\": [\r\n        \"58\",\r\n        \"57\"\r\n      ],\r\n      \"safari\": [\r\n        \"12\"\r\n      ]\r\n    },\r\n    \"ios 12.0\": {\r\n      \"devices\": [\r\n        \"iphone xr\",\r\n        \"iphone xs\",\r\n        \"iphone xs max\"\r\n      ]\r\n    },\r\n    \"android 9.0\": {\r\n      \"devices\": [\r\n        \"galaxy s9 plus\"\r\n      ]\r\n    }\r\n  }\r\n}");
Request request = new Request.Builder()
  .url("https://api.lambdatest.com/screenshots/v1/")
  .post(body)
  .addHeader("Content-Type", "application/json")
  .addHeader("Authorization", "Basic cmFtaXRkbGFtYmRhdGVzdDpBTIzdWprdFdhU3VCUnE5ak9qSW52QmFlbGlleUMwMFhhdlpVUA==")
  .addHeader("Accept", "*/*")
  .addHeader("Cache-Control", "no-cache")
  .addHeader("Host", "api.lambdatest.com")
  .addHeader("Accept-Encoding", "gzip, deflate")
  .addHeader("Connection", "keep-alive")
  .addHeader("cache-control", "no-cache")
  .build();

Response response = client.newCall(request).execute();

任何帮助将不胜感激。

Answer 1

您可以尝试在单独的方法中提取用于发出请求的所有代码，其中正文中的 url 是一个变量和一个方法参数。如果你把你需要的 url 放在一个数组中，你可以循环遍历数组并使用不同的 url 作为参数调用方法。

Answer 2

也许您可以尝试将代码块放入方法中。

 public void jsonCall(String url, String body) {
    OkHttpClient client = new OkHttpClient();

    MediaType mediaType = MediaType.parse("application/json");
    RequestBody body = RequestBody.create(mediaType, String.format("{\r\n  \"url\": \"%s\",\r\n  \"defer_time\": 5,\r\n  \"email\": true,\r\n  \"mac_res\": \"1024x768\",\r\n  \"win_res\": \"1366X768\",\r\n  \"smart_scroll\": true,\r\n  \"layout\": \"portrait\",\r\n  \"configs\": {\r\n    \"windows 10\": {\r\n      \"chrome\": [\r\n        \"76\",\r\n        \"75\",\r\n        \"74\"\r\n\r\n      ],\r\n      \"firefox\": [\r\n        \"67\",\r\n        \"66\"\r\n      ],\r\n      \"opera\": [\r\n        \"58\",\r\n        \"57\"\r\n      ],\r\n      \"ie\": [\r\n        \"11\"\r\n      ]\r\n    },\r\n    \"macos mojave\": {\r\n      \"chrome\": [\r\n        \"76\",\r\n        \"75\"\r\n      ],\r\n      \"firefox\": [\r\n        \"67\",\r\n        \"66\"\r\n      ],\r\n      \"opera\": [\r\n        \"58\",\r\n        \"57\"\r\n      ],\r\n      \"safari\": [\r\n        \"12\"\r\n      ]\r\n    },\r\n    \"ios 12.0\": {\r\n      \"devices\": [\r\n        \"iphone xr\",\r\n        \"iphone xs\",\r\n        \"iphone xs max\"\r\n      ]\r\n    },\r\n    \"android 9.0\": {\r\n      \"devices\": [\r\n        \"galaxy s9 plus\"\r\n      ]\r\n    }\r\n  }\r\n}", body));
    Request request = new Request.Builder()
            .url(url)
            .post(body)
            .addHeader("Content-Type", "application/json")
            .addHeader("Authorization", "Basic cmFtaXRkbGFtYmRhdGVzdDpBTIzdWprdFdhU3VCUnE5ak9qSW52QmFlbGlleUMwMFhhdlpVUA==")
            .addHeader("Accept", "*/*")
            .addHeader("Cache-Control", "no-cache")
            .addHeader("Host", "api.lambdatest.com")
            .addHeader("Accept-Encoding", "gzip, deflate")
            .addHeader("Connection", "keep-alive")
            .addHeader("cache-control", "no-cache")
            .build();

    Response response = client.newCall(request).execute();
}

public void callJson() {
    Map<String, String> urlAndBody = new HashMap<>();
    urlAndBody.put("https://api.lambdatest.com/screenshots/v1/", "https://www.nike.com");
    urlAndBody.put("https://api.lambdatest1.com/screenshots/v1/", "https://www.puma.com");
    urlAndBody.put("https://api.lambdatest2.com/screenshots/v1/", "https://www.adidas.com");
    // put more url body pair here

    urlAndBody.forEach((url, body) -> {
        this.jsonCall(url, body);
    });
}

用参数 url 替换那个 url。并根据需要多次调用此函数。每次只给不同的url？
