Eu realmente não tenho certeza onde mais procurar a resposta. Cada guia ou pergunta on-line diz para verificar client_max_body_size e isso resolve.
Para mim, no entanto, estou tentando fazer uma grande solicitação PUT para um arquivo PHP que está em meu próprio servidor.
Eu tenho ... client_max_body_size 32M; no bloco do servidor nginx.conf. Eu sei que funciona porque o wordpress corretamente tem o tamanho do upload definido para 32MB.
Além disso, descobri que preciso verificar 3 variáveis PHP, não me lembro exatamente o que elas eram, mas elas são grandes o bastante (em centenas de MB).
Talvez eu precise fazer algo com buffers? Eu não tenho ideia: (
O script que estou usando é um script de proxy para se comunicar com o serviço de terceiros. Ele registra todos os seus dados para a saída, e este é o log até agora ... não tenho certeza se isso poderia aludir a um problema.
Acho que isso abaixo é o que o servidor está tentando para enviar (porque está no arquivo de log e está gravando em STDOUT, então presumo que o script do proxy php esteja tentando gravar um arquivo de log de os cabeçalhos que está querendo enviar).
No entanto, quando uso as ferramentas de desenvolvimento do Chrome, não vejo Expect: 100-continue . Isso poderia ter alguma coisa a ver com isso?
Editar: Depois de ver o código fonte do PHP, parece que foi um 'bug' com 100-continue e isso estava bagunçando o script do proxy ... Então ignore toda a saída abaixo. Eu suponho que vou colocá-lo de qualquer maneira apenas no caso de ter outros bits úteis.

Não tenho certeza se isso ajuda ... mas aqui está o script de proxy.

você pode por favor anexar o seu nginx-conf relacionado?
você sabe se o pedido é transferido para os locais do php ou está parado @ nginx?
Então você pode fazer o upload via POST, mas não via PUT? Eu começaria a investigar esse problema; O que acontece quando você muda seu PUT para POST?
quando googling PUT 413: Request Entity Too Large nginx o mais referenciado é o que você já fez, e eu não começaria a mexer no cliente _ * _ temp-vars e temp_caching (atm).
