背景：

我正在尝试使用one-api向手机发送短信并接收交付状态。我POST向他们的服务器发出请求。JSON然后我从收到的响应中提取一个字符串。我使用该字符串向GET包含该 ID 的 URL 发出另一个请求。问题是当我提出GET请求时字符串会发生变化。虽然我从响应中提取它时是一样的，但不知道为什么它在 GET 请求过程中会发生变化。

遵循的方法和问题解释：

初始请求的响应POST`：

{"resourceReference":
     {"resourceURL":"https:\/\/oneapi-gw.gsma.com:443\/SendSmsService\/OneAPI_REST_v2_0\/routing\/2_0\/smsmessaging\/outbound\/tel:7511\/requests\/998371119"}
}

我提取了ID我在 url (998371119) 中收到的内容。我.split用来提取如下：

String tmp = (String)resourceReference.get("resourceURL");
String [] tmp2 = tmp.split("/");
String id = tmp2[(tmp2.length)-1].toString(); 
System.out.println(id); 
// the output is:998371119.

使用此 ID 创建另一个 url 来发送 GET 请求。

String url2 = "https://oneapi-gw.gsma.com/smssend/2_0/smsmessaging/outbound/tel:7511/requests/"+id+"/deliveryInfos"

当我发送GET请求时，ID 的最后 2 位数字似乎会自动更改，并且在发出 GET 请求后我会收到Response Codeas 。400以下是错误流：

    {  "requestError" : 
        {    "serviceException" : { 
                 "text" : "Invalid input value for message part requestIdentifier",
                 "variables" : [ 
                     "requestIdentifier", "998371122" 
                  ]    
              }
        }
    }

请注意服务器如何将 ID 解释为998371122（998371119我最初请求的）。最后 2 位数字变了。我想了很多，但我不知道为什么会这样。虽然当我curl用来发送GET请求时，一切正常。所以不是服务器问题。他们在我如何形成 url 或提取 ID 或发出 GET 请求方面存在一些问题。有什么建议么？提前致谢。

您可能需要的其他相关代码

这就是我提出GET请求的方式：

private String getResponseFromGETRequest(String accept, String url) {

    URL obj;
    StringBuffer response = new StringBuffer();;
    HttpURLConnection con;
    String authHeaderValue = new String(Base64.encode(credentials.getBytes()));
    //Credentals variable is a string storing "username:password"
    try {
        obj = new URL(url);
        con = (HttpURLConnection) obj.openConnection();
        con.setRequestProperty ("Authorization", "Basic " + authHeaderValue);

        // optional default is GET
        con.setRequestMethod("GET");

        //add request header
        con.setRequestProperty ("Accept", accept);
        //con.setRequestProperty("Content-Type", accept);

        int responseCode = con.getResponseCode();
        InputStream ipStream;
        if (con.getResponseCode() >= 400) {
            ipStream = con.getErrorStream();
        } else {
            ipStream = con.getInputStream();
        }

        System.out.println("Response Code : " + responseCode);
        BufferedReader in = new BufferedReader(
                new InputStreamReader(ipStream));
        String inputLine;

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        //print result
        System.out.println(response.toString());

    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        return "";
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        return "";
    }

    return response.toString();
}

最后两天后，这是一个奇怪的解决方案。事实证明解析很好，GET请求POST的形成也很好。POST在收到请求的响应后和发送另一个请求之前，我只延迟了 3 秒GET。这解决了它。 

try {
    Thread.sleep(3000);
} catch(InterruptedException ex) {
    Thread.currentThread().interrupt();
}
