golang几种post方式
bodyBuf := bytes.NewBufferString("")bodyWriter :
= multipart.NewWriter(bodyBuf)
//建立文件的http第一部分数据,文件信息
_, err := bodyWriter.CreateFormFile(paramName, path)
if err != nil {
return nil, err
}
//读取文件,当做http第二部分数据
fh, err := os.Open(path)
if err != nil {
return nil, err
}
//mulitipart/form-data时,需要获取自己关闭的boundary
boundary := bodyWriter.Boundary()
closeBuf := bytes.NewBufferString(fmt.Sprintf("\r\n--%s--\r\n", boundary))
//建立写入socket的reader对象
requestReader :=io.MultiReader(bodyBuf, fh, closeBuf)
fi, err := fh.Stat()
if err != nil {
return nil, err
}
req, err := http.NewRequest("POST", uri, requestReader)
if err != nil {
return nil, err
}
//设置http头
req.Header.Add("Content-Type", "multipart/form-data; boundary="+boundary)
req.ContentLength = fi.Size() + int64(bodyBuf.Len()) + int64(closeBuf.Len())
