# webcc
C++ client and server library for HTTP, REST and SOAP based on *Boost.Asio*.
Please turn to our [Wiki](https://github.com/sprinfall/webcc/wiki) for more tutorials and guides, or just follow the links below:

- [Logging](https://github.com/sprinfall/webcc/wiki/Logging)

- [SOAP Server Tutorial](https://github.com/sprinfall/webcc/wiki/SOAP-Server-Tutorial)
- [REST Server Tutorial](https://github.com/sprinfall/webcc/wiki/REST-Server-Tutorial)
## Quickstart
A complete client example:
```cpp
#include <iostream>
#include "webcc/http_client_session.h"
#include "webcc/logger.h"
int main() {
WEBCC_LOG_INIT("", webcc::LOG_CONSOLE);
try {
webcc::HttpClientSession session;
auto r = session.Request(webcc::HttpRequestBuilder{}.Get().
url("http://httpbin.org/get")());
std::cout << r->content() << std::endl;
} catch (const webcc::Exception& e) {
std::cout << e.what() << std::endl;
}
return 0;
}
```
List GitHub public events:
```cpp
auto r = session.Request(webcc::HttpRequestBuilder{}.Get().
url("https://api.github.com/events")());
// Parse r->content() to JSON object...
```
For more examples, see the Wiki tutorials.
## Build Instructions
### General
A lot of C++11 features are used, e.g., `std::move`.
VS2015 and above is required for building `webcc` on Windows. No support for VS2013 any more!
[CMake 3.1.0+](https://cmake.org/) is used as the build system. But if you don't use CMake, you can just copy the `src/webcc` folder to your own project then manage it by yourself, though some changes are needed to make it work. See [Wiki/Integrate Into Your Project]( https://github.com/sprinfall/webcc/wiki/Integrate-Into-Your-Project) for more details.
[C++ Boost](https://www.boost.org/) should be 1.66+ because Asio made some broken changes to the API since 1.66.
OpenSSL is required for HTTPS support. Already included in the `third_party` folder for Windows.
Zlib is required for compressing and decompressing HTTP requests and responses.
### Build Options
The following CMake options determine how you build the projects. They are quite self-explanatory.
```cmake
option(WEBCC_ENABLE_SOAP "Enable SOAP support (need pugixml)?" ON)
option(WEBCC_ENABLE_UNITTEST "Build unit test?" ON)
option(WEBCC_ENABLE_EXAMPLES "Build examples?" ON)
set(WEBCC_ENABLE_LOG 1 CACHE STRING "Enable logging? (0:OFF, 1:ON)")
set(WEBCC_LOG_LEVEL 2 CACHE STRING "Log level (0:VERB, 1:INFO, 2:WARN, 3:ERRO or 4:FATA)")
```
Options `WEBCC_ENABLE_LOG` and `WEBCC_LOG_LEVEL` together define how logging behaves. See [Wiki/Logging](https://github.com/sprinfall/webcc/wiki/Logging) for more details.
If `WEBCC_ENABLE_SOAP` is `1`, **pugixml** (already included) is used to parse and compose XML strings.
### Build On Linux
Create a build folder under the root (or any other) directory, and `cd` to it:
```bash
mkdir build
cd build
```
Generate Makefiles with the following command:
```bash
cmake -G"Unix Makefiles" \
-DCMAKE_INSTALL_PREFIX=~ \
-DWEBCC_ENABLE_LOG=1 \
-DWEBCC_LOG_LEVEL=2 \
-DWEBCC_ENABLE_SOAP=ON \
-DWEBCC_ENABLE_UNITTEST=OFF \
-DWEBCC_ENABLE_EXAMPLES=ON \
..
```
Feel free to change the build options.
CMake variable `CMAKE_INSTALL_PREFIX` defines where to install the output library and header files. The default is `/usr/local`.
If everything is OK, then you can build with `make`:
```bash
$ make -j4 # or -j8, depending on how many CPU cores you have.
```
Then install:
```bash
$ make install
```
