Question

下面是我正在使用的nginx conf（nginx是一个docker容器） - Nginx用作所有后端api服务器的代理服务器。当我尝试上传文件时，如果大小超过1 MB，我会收到错误。尝试了所有可能的解决方案，但是没有解决。任何帮助都会有用。

#include <SPI.h>
#include <MFRC522.h>

#define SS_PIN 10
#define RST_PIN 9
MFRC522 mfrc522(SS_PIN, RST_PIN);   // Create MFRC522 instance.

void setup() {
    Serial.begin(9600); // Initialize serial communications with the PC
    SPI.begin();            // Init SPI bus
    mfrc522.PCD_Init(); // Init MFRC522 card    
}

void loop() {
    String code = "";
    // Look for new cards
    if ( ! mfrc522.PICC_IsNewCardPresent()) {
        return;
    }

    // Select one of the cards
    if ( ! mfrc522.PICC_ReadCardSerial()) {
        return;
    }

    for (byte i = 0; i < mfrc522.uid.size; i++) {
      code += String(mfrc522.uid.uidByte[i] < 0x10 ? "0" :"");
      code += String(mfrc522.uid.uidByte[i], HEX);
    }
    Serial.println(code);
    mfrc522.PICC_HaltA();
}

我可以上传任何小于1MB的文件，但是上传的文件较大。低于错误 -

Answer 1

upload_max_filesize上的php.ini设置是什么？还尝试在http指令（在/etc/nginx/nginx.conf中）以及location指令中添加client_max_body_size 10M;。

Answer 2

我有一种问题。它通过微调下一个（后面的nginx）Web服务器来解决。但是，http部分中的一些设置可以提供帮助

default_type  application/octet-stream;
sendfile        on;
keepalive_timeout  300;
client_max_body_size 100m;
gzip  on;

Answer 3

错误消息表明您的后端（Java服务器）已关闭连接。检查日志以找出问题来源。
