错误“当试图将请求体解析为JSON时，无法读取它”

Question

我们的开发人员在API (Bright珍珠)上遇到了一些小问题，在尝试运行下面的脚本时，收到了一个“请求体无法读取，同时试图将其解析为JSON”的消息。有人对这个可能的问题有什么想法吗？在此之前，非常感谢您。

<?php
define ("DB_HOST","localhost");
define ("DB_USER","busi6292_REMOVED");
define ("DB_PASSWORD","REMOVED");
define ("DB_DATABASE","busi6292_REMOVED");

$link = @mysql_connect(DB_HOST, DB_USER, DB_PASSWORD)
or die ('I cannot connect to the database because: ' . @mysql_error());
@mysql_select_db (DB_DATABASE);
mysql_set_charset('utf8',$link);

我不能完全确定，但我相信您的问题在于第二个curl请求。您正在传递一个标头-> Content-Type: application/json;charset=UTF-8 <-连同您的请求。但是，将数据编码为url字符串-> CURLOPT_POSTFIELDS,http_build_query($newShippingWarehouseDetails));。

试试这个：

更改如下：

CURLOPT_POSTFIELDS,http_build_query($newShippingWarehouseDetails));

to此文：

CURLOPT_POSTFIELDS, json_encode($newShippingWarehouseDetails));

如果数据被正确地编码为JSON，我认为您应该没有问题。
