我构建了一个存储过程来调用 Web 服务并从端点检索响应。除了一些例外之外，一切都运行良好。我使用
sp_OACreatesp_OAMethodsp_OAGetProperty对象 ID 响应失败：ODSOLE 扩展过程。描述：为此字符串或二进制列或参数指定的源数据太长
我还有一个状态文本回复：
对于输入字符串：“ D”“
400`and a status of "
根据我的日志，我的请求“发送”成功并且消息被成功接收。这是没有成功返回的响应。
奇怪的是，我联系了我的请求响应方的人员，他们正在发回一条我已从其他请求成功收到的消息，如下：
<responses success="true">
<response key="quoteRequest" service="quoteRequest" success="false"
message="Processing error received for quote request. Support has been notified and is looking into the error.">
</response>
</responses>
我知道这个 SQL 函数的最大长度是 4000，即使请求成功，响应也永远不会那么长。
这是我用来执行的SQL。我会包含 URL，但我觉得回复公司不会喜欢这样...:

当响应远不接近最大长度时，有人遇到过这个问题吗？感谢您的帮助！
您应该将内容长度发送到网络服务器。 在您的代码中，可以这样做：
SET @len = LEN(@in_vchXMLMessage);
EXEC @v_nResult = sp_OAMethod @v_nObject,'setRequestHeader',NULL,'Content-Length',@len;
IF @v_nResult <> 0
BEGIN
EXEC sp_OAGetErrorInfo @v_nObject, @v_vchSource OUT, @v_vchDesc OUT
SET @v_vchCode = N'-20004';
SET @v_vchMsg = N'Lengh Failed on Object ID ' + ISNULL(@v_vchSource, '') + ' description ' + ISNULL(@v_vchDesc , '')
GOTO DESTROY;
END
SELECT 'set len', @v_nResult
您应该在发送主要消息之前执行此操作。 希望这有帮助
使用表格类型以获得无限的响应。
将代码中的行替换如下：
DECLARE @ResponseTable as table(Json_Table nvarchar(max))
EXEC sp_OAMethod @token, 'ResponseText', @ResponseTable OUTPUT
INSERT into @ResponseTable(Json_Table) EXEC sp_OAGetProperty @token, 'ResponseText'
SELECT * from @ResponseTable
我也遇到这个问题了。没有解决方案可以解决此问题，但通过使用以下代码，您可以获得所有响应文本。
`EXEC @ret3 = sp_OAGetProperty @internalToken, 'responseText';
如果@ret3 <> 0
开始
将 @src 声明为 VARCHAR(100)
将 @desc 声明为 VARCHAR(200)
EXEC sp_OAGetErrorInfo @internalToken、@src OUT、@desc OUT
选择@src + '-' + @desc
结束`
