我们最近在我们的azure网站和我们的网络API之间启用了HTTP2流量。 这是通过azure门户中的开关启用的。 Web应用程序向Web API发出的第一个请求失败： （失败）net :: ERR_SPDY_PROTOCOL_ERROR
看起来这个请求看起来不像是api。 我们已尝试将这两个应用程序升级到.NET 4.6.1，假设旧版本不支持新的HTTP2协议。 我正在努力在chrome中的dev工具中找到任何用途，或者使用chrome中的高级跟踪工具。 以下是我们在使用高级Chrome网络工具（chrome：// net-internals /＃events）检查api请求的详细HTTP2会话事件跟踪时看到的错误：

我觉得应该有更多关于如何让你的应用程序使用http2进行通信的在线信息，但我们找不到任何东西。
感谢任何帮助！

修改
我还包含了我们正在制作的HTTP2请求，从chrome中的HAR文件中保存：
"request": {
"method": "OPTIONS",
"url": "https://autoservice.compareunittest.com/api/mi/pagevisit",
"httpVersion": "http/2.0",
"headers": [

},
{

},
{

当我切换回HTTP1并且它正确响应时，这是API的响应：
"response": {
"status": 200,
"statusText": "OK",
"httpVersion": "HTTP/1.1",
"headers": [
{

"value": "OPTIONS, TRACE, GET, HEAD, POST"
},

},

答案 0 :(得分：1)
HTTP_TRANSACTION_READ_HEADERS之后错误发生的事实。
HTTP / 2对HTTP标头更加严格，而HTTP / 1对无效标头非常宽容。因此，如果HTTP标头中有冒号或空格，则可能是原因。
通常情况下，您会在chrome://net-internals/#events中看到比您显示的更多信息，如果这是原因，这应该有助于查明导致问题的标题。尝试转到chrome://net-internals/#http2，了解您是否获得了更多信息。
有关详细信息，请参阅this blog post。或者，如果您将HTTP标头（来自HTTP / 1请求）添加到问题中，那么我们可能会发现某些内容。
答案 1 :(得分：0)
因此，在尝试了上述所有操作后，从标题中删除所有小写字符串，删除＆＃34; __＆＃34;从请求令牌，没有任何工作。 我们在防伪请求中连接了两个令牌，并在API端将它们分开。 我注意到第二个静态字符串有一个＆＃34; =＆＃34;在字符串的末尾。 我们从所有应用中删除了它，现在它正在处理所有HTTP1和2个请求！
感谢您的帮助！检查标题中的字符是我从中学到的。
