HTTPS Client 露
This example demonstrates a basic synchronous HTTPS client using boost::beast .
http::request
A typical HTTP request.
Defined in header < boost/beast/http/message.hpp >
Member Functions
This container is derived from the Fields template type. To understand all of the members of this class it is necessary to view the declaration for the Fields type. When using the default fields container, those declarations are in http :: fields . A message can be a request or response, depending on the isRequest template argument value. Requests and responses have different types; functions may be overloaded based on the type if desired. The Body template argument type determines the model used to read or write the content body of the message. Newly constructed messages objects have version set to HTTP/1.1. Newly constructed response objects also have result code set to http :: ok .

Reading large response body 馃挕
This example presents how to increase the default limit of the response body size, thus the content larger than the default 8MB can be read.

1 Answer Sorted by: 4 In the operator= for the body is not available because your request is declared with template http::dynamic_body: http::request<http::dynamic_body> req_; Change your template argument to http::string_body and the operator= will work http::response<http::string_body> req_; It will be possible to compile the code

By the way, it looks like you are making a copy of the string. If you know that the string is going to exist at least until the completion handler is called, you can use request<span_body<char>> instead of request<string_body> and make it a non-owning reference.
#1304 Closed JanVerschaeren opened this issue on Nov 15, 2018 路 4 comments JanVerschaeren commented on Nov 15, 2018 How does this serializer work? Does it convert the data of the opened file to a string and then sends a post request with a string_body type?
Body Type Members Value Type The value_type nested type allows the body to define the declaration of the body type as it appears in the message. This can be any type. For example, a body's value type may specify std::vector<char> or std::list<std::string>.
1 I'm writing a boost::beast server, and I'm having trouble figuring out how to use the different request flavours. When a connection is accepted, I do this to read the request: I call async_read (), which populates my request<string_body> I look at the request's method and target to dispatch it to whoever can handle that request

Return the request-method verb. Set the request-method. method_string. Return the request-method as a string. need_eof. Returns true if the message semantics require an end of file. operator= Assignment. payload_size. Returns the payload size of the body in octets if possible. prepare_payload. Prepare the message payload fields for the body. reason
1 Answer Sorted by: 5 In general, you can use the http::buffer_body to handle arbitrarily large request/response messages. If you specifically want to read/write from a filesystem file, you can have the http::file_body instead. Full Demo buffer_body
aikuimail. Dear vinniefalco: I really love this library, but I don't know how to send a https with the beast, the server dose not have a certificate with the https.
Tell the server to send smaller bodies. But really, you need to refactor your code to pass the parser around. If this is an impossible task you have bigger problems.
