为什么 FedEx API 返回编码字符？

Question

FedEx 地址验证 API 返回编码字符和 400 错误请求错误。这是我的请求正文，由于明显的原因，秘密密钥被屏蔽了：

POST /address/v1/addresses/resolve HTTP/1.1
Content-Type: application/json
x-customer-transaction-id: 
x-locale: en_US
authorization: Bearer {my secret key}
{
  "addressesToValidate": [
   {
      "address":{
         "streetLines":[
            "1234 Example Rd.",
            ""
         ],
         "city":"Morris",
         "stateOrProvinceCode":"AL",
         "postalCode":"35116",
         "countryCode":"US"
      }
   }]
}

这就是编码响应的样子：

HTTP/1.1 400 BadRequest
Content-Type: application/json;charset=UTF-8
Content-Encoding: gzip
Connection: close
Server-Timing: cdn-cache; desc=MISS,edge; dur=115,origin; dur=62

Answer 1

答案是查找如何用我使用的语言解压缩 gzip。通过 Outsystems，我下载了一个名为 gzip 的伪造组件，该组件可以将二进制文件与明文文件进行压缩和解压缩。

在 java 中解压缩 fedex api 错误消息的示例语法

Public apiCall()
{

 try{
  // api call
}catch(Exception e)
{
    String errorMessage = deCompress(e.getResponseBodyAsByteArray());
}

}    


private static String deCompress(byte[] str) throws IOException{
         String decodedString= null;
         ByteArrayInputStream byteA = new ByteArrayInputStream(str);
         final GZIPInputStream gzipInput = new GZIPInputStream(byteA);
         InputStreamReader reader = new InputStreamReader(gzipInput);
         BufferedReader in = new BufferedReader(reader);
         String readed="";
         String errormessage = "";
         while ((readed = in.readLine()) != null) {  
             System.out.println(readed);
             errormessage=readed;
         }
         
        return errormessage;

    }

如果您使用 PHP，这是适合我的解决方案：

// Execute request and get response
$response = curl_exec($ch);

// Check if the response is compressed and decompress if necessary
if (substr($response, 0, 2) == "\x1f\x8b") {
    // It's GZIP compressed, so decompress
    $response = gzdecode($response);
}
