message轉(zhuǎn)發(fā)json字符串時(shí)遇到的問題
項(xiàng)目用gateway搭建的TCP服務(wù)器，用來做客戶端之間的轉(zhuǎn)發(fā)，轉(zhuǎn)發(fā)前會先將message打包一個json字符串，然后進(jìn)行轉(zhuǎn)發(fā)，
；當(dāng)message為單純字符串的時(shí)候，這個沒有問題，結(jié)果是這樣
；但是當(dāng)$message本身就是一個json字符串的時(shí)候，轉(zhuǎn)發(fā)就會出錯，并且壓根就不會進(jìn)行轉(zhuǎn)發(fā)，請問這種message是json字符串的情況，該怎么進(jìn)行處理。
$message如下:
{"data":[{"avg":149.0269927978516,"ch1":150.8728485107422,"ch2":147.1811370849609,"ch3":150.5439910888672,"ch4":150.6110382080078,"ell":3.691711425781250,"max":150.8728485107422,"min":147.1811370849609}],"dev_temp":21.30,"id":"20201218104516580","length":0.0,"negative_value":0.0,"positive_value":3.0,"product_type":"102系列","real_length":0.0,"speed":0.0,"standard_value":154.70,"steel_no":757,"steel_temp":972.2577514648438,"wind_pressure":785.0}
直接這樣轉(zhuǎn)發(fā)可以收到,
打包成json字符串后就無法收到

應(yīng)該是發(fā)出去了，但是你們客戶端不識別，導(dǎo)致以為沒發(fā)出去。
抓包看下發(fā)出去沒
