I don't have a good explanation as the script works for me and the URL is valid. Maybe outgoing requests from your script are blocked by the firewall? Try to disable the firewall for outgoing calls or try running the script from a different computer.
Ok, I did that. There is no timeout anymore but whether I use your or my script the saved. If I try to view it Windows displays an error saying that it seems like it is damaged or corrupted. Did you get a perfectly fine image which is viewable? Show 1 more comment. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.

Question feed. Note that :close performs a connection:shutdown prior to releasing resources. Returns the next peer initiated stream on the connection. This function can be used to yield and "listen" for incoming HTTP streams. Provide a callback to get called when the connection becomes idle i.
When called it will receive the connection as the first argument. Returns the previous handler. Within a stream there may be a number of "header" blocks as well as data known as the "body". Convenience wrapper equivalent to stream. Retrieves the next complete headers object i. Write the given headers object to the stream. The function takes a flag indicating if this is the last chunk in the stream, if true the stream will be closed.
If timeout is specified, the stream will wait for the send to complete until timeout is exceeded. Returns the next chunk of the http body from the socket, potentially yielding for up to timeout seconds. Reads the entire body from the stream and return it as a string.
Reads n characters bytes of body from the stream and return them as a string. If the stream ends before n characters are read then returns the partial result. Reads in body data from the stream until the lua pattern pattern is found and returns the data as a string. Reads the body from the stream and saves it to the lua file handle file. Reads the body from the stream into a temporary file and returns a lua file handle.
Places str back on the incoming data buffer, allowing it to be returned again on a subsequent command "un-gets" the data. Writes the string chunk to the stream. Writes the string str to the stream and ends the stream. Writes the contents of file file to the stream and ends the stream. Results are only consistent between underlying implementations when parameters and results are in the range of 0 to 0x7fffffff. Negotiates the HTTP settings with the remote server. If TLS has been specified, this function instantiates the encryption tunnel.
Parameters are as follows:. This function returns a new connection to an HTTP server. Constructor for a new connection. Takes a cqueues socket object, a connection type string and a numeric HTTP version number. Valid values for the connection type are "client" and "server".
Valid values for the version number are 1 and 1. Returns the newly initialized connection object. Shut down is as graceful as possible: pipelined streams are shutdown , then the underlying socket is shut down in the appropriate direction s. If it contains "r" it will shut down reading, if it contains "w" it will shut down writing. The default is "rw" , i. Clears errors to allow for further read or write operations on the connection. Returns the error number of existing errors. This function is used to recover from known errors.
Used to hand the reference of the connection socket to another object. Resets the socket to defaults and returns the single existing reference of the socket to the calling routine. Reads a request line from the socket. Returns the request method, requested path and HTTP version for an incoming request. If the incoming chunk is not a valid HTTP request line, nil is returned.
Reads a line of input from the socket. If the input is a valid status line, the HTTP version 1 or 1. If the socket could not be read, returns nil , an error message and an error number. This function will yield until a MIME compliant header item is received or until timeout is exceeded. If the header could not be read, the function returns nil an error and an error message.
Checks for an empty line, which indicates the end of the HTTP headers. Returns true if an empty line is received. Any other value is pushed back on the socket receive buffer unget and the function returns false. This function will yield waiting for input from the socket or until timeout is exceeded.
Returns nil , an error and an error message if the socket cannot be read. Get len number of bytes from the socket. Use a negative number for up to that number of bytes. This function will yield and wait on the socket if length of the buffered body is less than len.
Asserts if len is not a number. Reads the entire request body. This function will yield until the body is complete or timeout is expired. If the read fails the function returns nil , an error message and an error number. Reads the next available line of data from the request and returns the chunk and any chunk extensions.
This function will yield until chunk size is received or timeout is exceeded. If the chunk size is indicated as 0 then false and any chunk extensions are returned.
Returns nil , an error message and an error number if there was an error reading reading the chunk header or the socket. Writes the opening HTTP 1. Yields until success or timeout. If the write fails, returns nil , an error message and an error number. Writes an HTTP status line to the socket buffer. If the write fails, the function returns nil , an error message and an error number. Writes a header item to the socket buffer as a key:value string. Returns nil , an error message and an error if the write fails.
This function will flush all outstanding data in the socket output buffer. Writes a chunk of data to the socket. Will yield until complete or timeout is exceeded. Returns nil , an error message and an error number if the write fails. Note that the connection will not be immediately flushed to the remote server; normally this will occur when trailers are written. Writes the contents of body to the socket and flushes the socket output buffer immediately.
Yields until success or timeout is exceeded. A table mapping from status codes as strings to reason phrases for HTTP 1. Any unknown status codes return "Unassigned". Sets the state of the stream to new. Reads and returns a header block from the underlying connection. Does not take into account buffered header blocks. Reads and returns the next chunk as a string from the underlying connection. Does not take into account buffered chunks. An HTTP 2 connection can have multiple streams actively transmitting data at once, hence an http.
Takes a cqueues socket object, a connection type string and an optional table of HTTP 2 settings. Returns the newly initialized connection object in a non-connected state. A type of error object that encapsulates HTTP 2 error information. An http. A table containing errors as defined by the HTTP 2 specification. It can be indexed by error name e. Returns a boolean indicating if the object ob is an http. Creates a new error object from the passed table. The table should have the form of an error object i.
If cond is falsy i. The module follows the stream interface as well as HTTP 2 specific functions. An ordered list of header fields. Each headers object has an index by field name to efficiently retrieve values by key.
Keep in mind that there can be multiple values for a given field name. As noted in the Conventions section, HTTP 1 request and status line fields are passed around inside of headers objects under keys ":authority" , ":method" , ":path" , ":scheme" and ":status" as defined in HTTP 2. As such, they are all kept in string form important to remember for the ":status" field.
Returns all headers with the given name in a table. The table will contain a field.
