瞬态400错误 [英] Transient 400 errors
问题描述
运行100多批面部检测时出现问题。它会因400个错误请求而失败，但并非总是如此（同时重新尝试单个检测以及整个批次）。我已经运行了429个错误并实施了速率限制，所以
我希望这是一个明显的问题。我附上相关http事务的细节。首先，最后一个成功，然后是失败，然后尝试复制错误（没有复制）。哈希被混淆了。为了调试
方便，我删除了所有三个事务共有的所有行，并且我也附加了该分析。将这三个电话分开很少。欢迎任何建议。谢谢
I am having some problem when running a 100-long batch of face detections. It will fail with 400 bad request, but not always (both re-attempting single detections as well the whole batch). I have already run in 429 errors and implemented rate limits, so I expect this to be a distinct problem. I attach the detail of related http transactions. First, the last successful one, followed by the failed on, followed by an attempt to replicate the error (did not replicate). Hashes have been obfuscated. For debugging convenience, I eliminated all lines common to all three transaction, and I attach also that analysis. There is very little to separate the three calls. Any suggestion welcome. Thanks

推荐答案
由于您指向存储在另一个站点中的图像，访问这些文件是否会出错？该网站可能正在做些什么 很奇怪？
Since you are pointing to images stored in another site, could it be something going wrong accessing those file? That site might be doing something weird?
您可以将图像下载到本地计算机并尝试使用'Content-type'：'application / octet-stream'方法吗？
Can you download the images to your local machine and try using the 'Content-type': 'application/octet-stream' method?
