Java 为什么本机HTTP POST无法工作?
大家好, 我在输入凭证时使用失眠测试了这个API,得到了一个JSON响应,因此我知道API工作正常,凭证正确。我不熟悉React Native,我不知道是否使用body:JSON.stringify正确添加了参数。。。显然,我已经用“X”s替换了信息。在swift中,我也能够得到响应,但是当我试图在react native中重新创建API调用时,我得到了错误Java 为什么本机HTTP POST无法工作?,java,node.js,reactjs,react-native,Java,Node.js,Reactjs,React Native,大家好, 我在输入凭证时使用失眠测试了这个API,得到了一个JSON响应,因此我知道API工作正常,凭证正确。我不熟悉React Native,我不知道是否使用body:JSON.stringify正确添加了参数。。。显然,我已经用“X”s替换了信息。在swift中,我也能够得到响应,但是当我试图在react native中重新创建API调用时,我得到了错误 export const login = () => { return async (dispatch) => {

JSON解析错误:意外的EOF
通常是
尝试将不可转换的json响应(如Html响应)转换为json时出错
为了安全起见,我通常首先使用将其转换为字符串,然后(res=>res.text())
再使用console.log()
或alert()
将其转换为字符串,以证明响应是否可转换为json,而不显示react-native的红框消息
如果响应是有效的json,您可以使用json.parse(responseText)
