更新:关于解决方案，请参阅下面Alexey的评论
我正在尝试什么，我认为这将是一个微不足道的功能采取一些有效的Json数据，并将其发布到远程url
我已经尝试了每一个例子，我可以找到接近这个在StackOverflow上，接收端总是有一个空的有效载荷。
我排除了接收端，因为可以这样做:
curl -XPOST 'http://supersecreturl/mypost' -d '[{"i sware to ritchie":"this json is 100 percent valid"},{"i can even":"copy and paste it into a curl POST request and receive it flawlessly on the remote side"}]'
请帮帮我，我都快疯了
/// Here is approximately my code - had to remove the valid url and the JSON content
func PutArticlesJSON(c appengine.Context, articles []*Articlez) (*http.Response){
url := "http://mysecreturl/mypost"
client := urlfetch.Client(c)
jsonarts, _ := json.Marshal(articles)
c.Debugf(" --- What do we have - %v", string(jsonarts)) /// the appengine log shows exactly valid json at this point, such as:
/*
[{"i sware to ritchie":"this json is 100 percent valid"},{"i can even":"copy and paste it into a curl POST request and receive it flawless on the remote side"}]
*/
// tried this way too....
//req, err := http.NewRequest("POST", url, strings.NewReader(string(jsonarts)))
//
req, err := http.NewRequest("POST", url, bytes.NewBuffer(string(jsonStr))) /// on the receiving side, the payload is completely empty no matter what I try
req.Header.Set("Content-Type", "application/json")
resp, err := client.Do(req)
if err != nil {
panic(err)
}
defer resp.Body.Close()
body, _ := ioutil.ReadAll(resp.Body)
return resp
}

from flask import Flask
from flask import request
import urllib
import json
app = Flask(__name__)
@app.route('/mypost', methods = ['GET','POST'])
def esput():
datapack = request.form
datastream = request.stream
with open("/tmp/log", "a") as myf:
myf.write(str(datastream))
myf.write(str(datapack))
myf.write("n")
return "all good"

app.run(threaded=True,host='0.0.0.0',port='333',debug=False)
这里有两个问题。
- 虽然你认为你正在发送一个有效的Json，你不是。
- NewBuffer应该接收[]字节，而不是字符串
试着这样写:
s := `[{"i sware to ritchie":"this json is 100 percent valid"},{"i can even":"copy and paste it into a curl POST request and receive it flawless on the remote side"}]`
req, err := http.NewRequest("POST", url, bytes.NewBuffer([]byte(fmt.Sprintf(`{"data":%s}`, s))))
