但是我从Google服务器收到400个错误的请求作为响应:请求失败:错误的请求(400)

However I get 400 bad request as a response from the Google servers: Request failed: bad request (400)

有什么想法为什么会发生以及如何解决?

Any ideas why this is happening and how I can fix it?

有趣的行为:如果有< = 3个批处理请求，它可以工作，但是如果有更多则不起作用.

interesting behavior: it works if there are <= 3 batched requests but if there are more it doesn't.

推荐答案

我注意到两件事:

(1)第一部分Content-Type之前的空格

(1) the space before the Content-Type on the first part

(2)在POST的末尾(在其自己的行上等)缺少最后一个"--737d0154-1999-455c-9886-65d7121a1382--"，请注意后面的-"边界...

(2) missing a final "--737d0154-1999-455c-9886-65d7121a1382--" at the very end of the POST (on it's own line, etc), note the trailing "--" AFTER it the boundary as well...
