我试图部署我的webapp在我的域，一切似乎工作的时刻，但最后几个步骤。
当我运行我的前端时，它确实成功地运行了“GET”请求，但是当我想编辑，创建或删除一些东西时，我的后端返回HTTP：403禁止。
我不知道为什么。使用Postman，所有调用都成功，只是使用我的webapp返回失败的请求
下面是我的nginx.conf：

`server {
    listen 80 default_server;
    server_name DOMAIN.com;

    location / {
        root /usr/share/nginx/html;
        index  index.html index.htm;
        try_files $uri $uri/ /index.html;
    }

    location /urs {
        rewrite /api/(.*) /$1  break;
        proxy_pass http://service:9001;
        proxy_pass_request_headers on;
        default_type  application/json;
    }
}`

下面是我docker-composed文件：

和我的React应用的Dockerfile：

`# pull official base image
FROM node:20 AS builder

# Set the working directory to /client inside the container where the UI will be located at
# as if we would use "cd" in linux, if the folder does not exist, it will create the folder under the given path
WORKDIR /usr/src/client

# Copy app files to workdir inside the docker container
COPY package*.json ./

# Install dependencies (npm ci makes sure the exact versions in the lockfile gets installed)
RUN npm ci

# Copy all of the project files into the docker container
COPY . .

# RUN the build after installing dependencies and the "COPY" of the whole source code
RUN npm run build

##########################
# Use the official Nginx base image with Alpine Linux as the base image for the final production container.
# Nginx will be used to serve the static files generated by the React app.
FROM nginx:alpine

# Set the working directory inside the container to /usr/share/nginx/html, where Nginx serves the static content.
WORKDIR /usr/share/nginx/html

# Remove the default Nginx configuration file that comes with the image.
# We will replace it with our custom configuration file.
RUN rm /etc/nginx/conf.d/default.conf

# Copy the custom Nginx configuration file from the host (your machine) to the container.
# This configuration file will be used by Nginx to serve the React app and handle incoming requests.
COPY conf/nginx.conf /etc/nginx/conf.d/default.conf

# Remove all the existing files in the /usr/share/nginx/html directory to clear any default content that Nginx might have placed there.
RUN rm -rf ./*

# Copy the production build files of the React app (generated in the previous build stage) from the "builder" stage into the /usr/share/nginx/html directory.
# This makes the built React app available to Nginx for serving.
COPY --from=builder /usr/src/client/build .

# Set the default command that will run when the container starts.
# This command starts Nginx in the foreground to serve the React app and keeps the container running.
ENTRYPOINT ["nginx", "-g", "daemon off;"]

在这里，您可以看到使用“Postman”的第一个调用使用“POST”API调用确实可以工作。但是在webapp上使用相同的调用并不起作用。
任何帮助都是感激的。
我已经尝试了几个配置和视频，也了解背后发生了什么，并试图修复它。以及检查我的CORS设置在我的后端，没有这些想法/建议成功：（
